Abstract
Treatment of ocular diseases presents unique challenges and opportunities for the clinician and for the clinical pharmacologist. Ophthalmic pharmaceuticals, typically given as liquids, require consideration of solubility, physiological pH, and osmolarity, as well as sterility and stability, which in turn requires optimal pharmaceutics. Ocular tissue levels are challenging to obtain in humans, and the clinical pharmacokinetics is typically blood levels, which are primarily related to safety, rather than efficacy. The eye is a closed compartment with multiple physiological barriers with esterases and transporters, but relatively little cytochrome oxidases. Delivery routes include topical, intravitreal, and systemic. Patient dosing involves not only adherence issues common to all chronic diseases, but also performance requirements on eye drop instillation. Therapeutically, ocular diseases and their pharmacological treatments include both those analogous to systemic diseases (e.g., inflammation, infection, and neuronal degeneration) and those unique to the eye (e.g., cataract and myopia).

Abdu N, Weldemariam DG, Goitom Tesfagaber A, Tewelde T, Tesfamariam EH. A cross-sectional study on the proper administration of eye medications and its determinants among outpatients attending Brhan Aini Ophthalmic National Referral Hospital in Asmara, Eritrea. BMJ Open 2024; 14:e084168. [PMID: 38604641 PMCID: PMC11015198 DOI: 10.1136/bmjopen-2024-084168] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/11/2024] [Accepted: 03/20/2024] [Indexed: 04/13/2024] Open
Abstract
OBJECTIVE This study aimed to assess the administration technique of eye medications, its determinants and disposal practices among ophthalmic outpatients. DESIGN An analytical cross-sectional study was conducted. SETTING Brhan Aini Ophthalmic National Referral Hospital in Asmara, Eritrea. PARTICIPANTS Samples of ophthalmic outpatients aged >18 years who visited Brhan Aini Ophthalmic National Referral Hospital in Asmara, Eritrea. Systematic random sampling was used to select the study participants. DATA COLLECTION AND ANALYSIS Data were collected from August 2021 to September 2021, using an interview-based questionnaire. The collected data were entered and analysed using CSPro (V.7.3) and SPSS (V.26), respectively. Descriptive statistics and independent samples t-test were performed. P-values less than 0.05 were considered as significant. RESULTS A total of 333 respondents with a mean age of 56.4 (SD: 18.76) years were recruited in the study. More than half of the respondents (57.4%) did not have any information on the time interval between two successive eye medications. However, only 16.5% of the respondents managed to close their tear ducts after the administration of eye medication. The mean (SD) score for proper administration of eye medication was 4.16 (1.07) out of 7.0. Female sex (p=0.002), the absence of glaucoma (p=0.035) and the presence of cataract (p=0.014) were significant determinants of the proper administration technique of eye medication. The most favoured disposal practice for unused and/or expired eye medications was disposing of regular garbage (79.9%). CONCLUSION This research revealed that there was an inappropriate administration technique and disposal practices of eye medications among ophthalmic outpatients. This requires immediate attention from policy-makers, programme managers and healthcare professionals to ensure the appropriate use of eye medications by the patients.

Ophthalmology 2024:S0161-6420(24)00206-9. [PMID: 38582155 DOI: 10.1016/j.ophtha.2024.03.025] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/10/2024] [Revised: 03/22/2024] [Accepted: 03/28/2024] [Indexed: 04/08/2024] Open
Abstract
PURPOSE To compare the effectiveness and safety of a single injection of subconjunctival triamcinolone acetonide (TA) with that of postoperative topical prednisolone acetate (PA) with and without nonsteroidal anti-inflammatory drugs (NSAIDs) for cataract surgery prophylaxis. DESIGN Retrospective, comparative effectiveness cohort study. PARTICIPANTS Patients at Kaiser Permanente Northern California from 2018 through 2021. INTERVENTION Exposure groups included topical PA with or without NSAID and subconjunctival injection of TA (Kenalog; Bristol-Myers-Squibb) 10 mg/ml or 40 mg/ml in a low dose (1.0-3.0 mg) or high dose (3.1-5.0 mg). MAIN OUTCOME MEASURES The adjusted odds ratio (OR) and 95% confidence interval (CI) for the association of postoperative macular edema (ME) and iritis diagnoses 15 to 120 days after surgery (effectiveness measures) and a glaucoma-related event (safety measure) between 15 days and 1 year after surgery. RESULTS Of 69 832 eligible patient-eyes, postoperative ME, iritis, and a glaucoma-related event occurred on average in 1.3%, 0.8%, and 3.4% of eyes in the topical groups and 0.8%, 0.5%, and 2.8% of eyes in the injection groups, respectively. In multivariable analysis, compared with the PA reference group, the PA plus NSAID group had a lower OR of ME (OR, 0.88; 95% CI, 0.74-1.04; P = 0.135). and all injection groups had even lower odds, with the high-dose TA 10-mg/ml group reaching statistical significance (OR, 0.64; 95% CI, 0.43-0.97; P = 0.033). A trend of lower odds of a postoperative iritis diagnosis was noted in the high-strength (40 mg/ml) groups. For postoperative glaucoma-related events, compared with PA, the TA 10-mg/ml low-dose group showed lower odds (OR, 0.69; 95% CI, 0.55-0.86; P = 0.001), the TA 10-mg/ml high-dose group showed similar odds (OR, 0.90; 95% CI, 0.70-1.15; P = 0.40), and the TA 40-mg/ml low-dose and high-dose groups showed higher odds of an event occurring (OR, 1.46 [95% CI, 0.98-2.18; P = 0.062] and OR, 2.14 [95% CI, 1.36-3.37; P = 0.001], respectively). CONCLUSIONS The TA 10-mg/ml high-dose (4 mg) group was associated with a lower risk of postoperative ME and a similar risk of glaucoma-related events compared with the topical groups.

Noninfectious Outcomes of Intravitreal Antibiotic Steroid Injection and Topical Nonsteroidal Antiinflammatory Drugs Versus Triple Drop Therapy After Cataract Surgery. Am J Ophthalmol 2024; 260:37-48. [PMID: 37944685 DOI: 10.1016/j.ajo.2023.11.003] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/10/2023] [Revised: 11/02/2023] [Accepted: 11/02/2023] [Indexed: 11/12/2023]
Abstract
PURPOSE To compare noninfectious outcomes of intravitreal antibiotic steroid (IVAS) injection (moxifloxacin-triamcinolone) and postoperative topical nonsteroidal antiinflammatory drugs (NSAID) with a standard 3-drop therapy (TDT) regimen (topical antibiotic, steroid, and NSAID) in patients after cataract surgery. DESIGN Retrospective comparative clinical cohort study. METHODS In 3 study centers in the United States, a total of 2143 eyes (N = 2143 patients) underwent cataract surgery with IVAS-NSAID or TDT between 2017 and 2022. Preoperative data were included, including patients' age, iris color, medical history, and ocular history. Postoperative data, including best-corrected visual acuity, intraocular pressure (IOP), and the need for IOP-lowering medications, were recorded at 1-week, 1-month, and 6-month time points. The primary outcome measures were postoperative complications, defined as persistent anterior chamber inflammation, persistent corneal edema (PCE), rebound inflammation, and cystoid macular edema, were compared between the 2 groups. RESULTS There were 1079 eyes in the IVAS-NSAID group and 1064 eyes in the TDT group. Best-corrected visual acuity and IOP were similar between IVAS-NSAID and TDT eyes at all time points. A portion (11.6%) of TDT eyes experienced postoperative complications compared with 6.5% in IVAS-NSAID eyes (P < .001). Femtosecond laser-assisted cataract surgery was associated with increased rates of PCE in IVAS-NSAID eyes, and eyes with dark irides had a higher incidence of cystoid macular edema, PCE, and rebound inflammation in the IVAS-NSAID group. CONCLUSION The IVAS-NSAID regimen overall had similar postoperative outcomes and fewer complications compared with the TDT regimen. IVAS-NSAID may be considered a safe alternative to topical regimens in non-femtosecond laser-assisted cataract surgery and patients with light irides.

Ophthalmic Physiol Opt 2024; 44:96-114. [PMID: 37985237 DOI: 10.1111/opo.13245] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/13/2023] [Revised: 10/05/2023] [Accepted: 10/06/2023] [Indexed: 11/22/2023]
Abstract
PURPOSE Nonadherence to medication reduces treatment effectiveness, and in chronic conditions it can significantly reduce health outcomes. In glaucoma, suboptimal adherence can lead to sight loss, which places a greater financial burden on society and reduces patients' quality of life. Interventions to improve adherence have so far had limited success and lack robust theoretical underpinnings. A better understanding of the determinants of medication adherence behaviour is needed in order to develop interventions that can target these factors more effectively. This systematic review aims to identify modifiable barriers and enablers to glaucoma medication adherence and identify factors most likely to influence adherence behaviour. RECENT FINDINGS We searched CINAHL, MEDLINE, PsycINFO, EMBASE, the Cochrane Library and sources of grey literature up to August 2022 for studies reporting determinants of glaucoma medication adherence. Data describing modifiable barriers/enablers to adherence were extracted and analysed using the Theoretical Domains Framework (TDF), a behavioural framework consisting of 14 domains representing theoretical factors that most likely influence behaviour. Data were deductively coded into one of the TDF domains and inductively analysed to generate themes. Key behavioural domains influencing medication adherence were identified by frequency of study coding, level of elaboration and expressed importance. Eighty-three studies were included in the final synthesis. Four key domains influencing glaucoma medication adherence were identified: 'Environmental Context and Resources', 'Knowledge', 'Skills' and 'Memory, Attention and decision processes'. Frequently reported barriers included complex eyedrop regimens, lack of patient understanding of their condition, forgetfulness and difficulties administering eyedrops. Whereas simplified treatments, knowledgeable educated patients and good patient-practitioner relationships were enablers to adherence. SUMMARY We identified multiple barriers and enablers affecting glaucoma medication adherence. Four theoretical domains were found to be key in influencing adherence behaviour. These findings can be used to underpin the development of behaviour change interventions that aim to improve medication adherence.

Abstract
Topical glaucoma medications are effective and safe, but they have numerous well-documented limitations that diminish their long-term utility and sustainability. These limitations can include high rates of nonadherence (with associated glaucoma progression), concerning side effects, inconsistent circadian intraocular pressure (IOP) control, complex dosing regimens, difficulty with self-administration, costs, and decreased quality of life. Despite these limitations, topical medications traditionally have been first-line in the glaucoma treatment algorithm, as no other minimally invasive treatment alternatives existed. In recent years, however, novel interventional therapies-including sustained-release drug-delivery platforms, selective laser trabeculoplasty, and micro-invasive glaucoma surgery procedures-have made it possible to intervene earlier without relying on topical medications. As a result, the topical medication-first treatment approach is being reevaluated in an overall shift toward earlier more proactive interventions.

[PMID: 38054183 PMCID: PMC10695020 DOI: 10.2147/opth.s435467] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/19/2023] [Accepted: 11/20/2023] [Indexed: 12/07/2023] Open
Abstract
Background One of the challenges of treating chronic ocular diseases like vernal keratoconjunctivitis (VKC), glaucoma, and ocular surface disease is patient adherence to topical medication. To support correct eye drop instillation, a variety of delivery aids have been developed for both single-dose and conventional multi-dose containers. Methods To evaluate Dropaid™ Single-dose, an eye drop delivery aid designed for single-dose containers, a usability study was conducted on 30 parents and caregivers of patients with VKC. After assessing the ability to squeeze a single eye drop from the single-dose container onto the eye of a pediatric medical dummy, the delivery aid was evaluated using an 11-point Likert scale on a variety of characteristics: from "very difficult" (-5) to "very easy" (+5). Results The majority of participants rated the task of opening the single-dose units (SDUs), preparing, and positioning the Dropaid™ Single-dose device as "very easy". When providing a single eye drop from the container, 87% of participants rated the Dropaid™ Single-dose device as either "very easy" or "easy", with a median rating score of +5.0 (interquartile range [IQR], 4.0-5.0). For general ease of use, 84% considered the delivery aid as either "very easy" or "easy", with a median score of +4.0 (IQR, 3.0-5.0). Most participants (93%) rated Dropaid™ Single-dose as either "very comfortable" or "comfortable" to hold, with a median score of +5.0 (IQR, 4.0-5.0). Conclusion The Dropaid™ Single-dose delivery aid demonstrated rapid learning and ease of use across all stages of application, including opening the container, eye drop administration, and handling comfort. Although designed for use with single-dose containers to help eye drop instillation in patients with VKC, Dropaid™ Single-dose may provide a wider utility across a range of other ocular diseases such as glaucoma and dry eye.

Abstract
PURPOSE To evaluate eye drop self-administration in a low-vision patient population and test whether a nose-pivoted drop delivery device (NPDD, GentleDrop) can improve eye drop delivery in these patients. DESIGN Repeated-measures case series. PARTICIPANTS Thirty subjects (58 eyes) with low vision, defined as best-corrected visual acuity worse than 20/60 or visual field worse than 20° in the better-seeing eye. METHODS We video-recorded subjects while self-administering eye drops using their own traditional delivery at baseline, after a standardized teaching, and with an NPDD. Two masked graders independently reviewed each drop delivery. Primary success was defined as the drop reaching the eye without the bottle touching the eye or eyelids. Subjects rated ease-of-use (1-10 scale, 10 = easiest) after each drop delivery and completed a satisfaction survey, which included asking whether subjects could place drops independently (1-5 scale, 5 = most independent). MAIN OUTCOME MEASURES Logistic-transformed generalized estimating equation regression to compare technique satisfaction, ease-of-use, independence, no contact, and success. RESULTS Primary success was observed in 30 (52%) of 58 eyes at baseline and increased to 44 eyes (76%) with an NPDD (P = 0.013). Bottle tip contact occurred in 23 (40%) of 58 eyes at baseline and 8 eyes (14%) with an NPDD (P = 0.004). Mean ease-of-use scores were 6.7 ± 3.1 at baseline and 8.3 ± 1.8 (P < 0.001) with an NPDD. Likewise, the NPDD improved success, bottle tip contact, and ease-of-use compared with post-teaching traditional delivery (P < 0.01). Twenty-two (73%) of 30 subjects preferred the NPDD to traditional delivery. Twenty-nine (97%) thought the NPDD was comfortable to use, and all would recommend the device. A subgroup analysis was performed on 16 subjects that self-reported difficulty instilling drops at baseline. The NPDD showed similar results, and it increased confidence in placing drops independently (4.6 ± 0.9) compared with baseline (2.7 ± 1.6, P < 0.001). Fifteen (94%) subjects in this subgroup preferred the NPDD. CONCLUSIONS Low-vision subjects struggled to self-administer eye drops. An NPDD can improve bottle tip contact, ease-of-use, satisfaction, and independence. Eye care providers could consider screening low-vision patients about difficulty with eye drop self-administration and recommending eye drop aids.

Abstract
Purpose: We aimed to determine the therapeutic efficacy of 0.05% topical cyclosporine A (CsA) for chronic ocular surface disease (OSD) in patients using benzalkonium chloride (BAK)-preserved antiglaucoma eye drops. Methods: A prospective, randomized, paired-eye, controlled clinical trial was conducted with participants who had been instilling at least one BAK-preserved topical antiglaucoma drug in both eyes for at least 6 months. Topical CsA was only applied in randomly selected unilateral eyes. Visual field (VF) indices, ocular surface parameters, tear meniscus height (TMH), and matrix metalloproteinase-9 (MMP-9) immunoassay were evaluated at baseline and at 2 and 4 months. Results: Seventy eyes from 35 participants were included in the study. The Schirmer I, tear breakup time, and TMH increased by 4.5 ± 8.6 mm (P < 0.01), 5.0 ± 5.3 s (P < 0.001), and 85.4 ± 159.0 μm (P < 0.01) in the treated eyes at 4 months from baseline, respectively. The ocular staining score and MMP-9 positivity in the treated eyes decreased by 2.2 ± 1.3 (P < 0.001) and 0.7 ± 0.9 points (P < 0.001), respectively, at 4 months. In untreated eyes, only TMH increased by 41.4 ± 92.1 μm (P = 0.016) from baseline to 4 months. In VF indices, the tracking failure frequency was 19.09% ± 21.62%, and the test duration was 336.0 ± 79.5 s in the treated eyes at 4 months, which were lower than 34.37% ± 23.13% (P < 0.001) and 375.9 ± 70.7 s (P < 0.05) in the nontreated eyes. Conclusion: Application of topical 0.05% CsA significantly improved the OSD parameters and the reliability indices of VF tests. This study was registered with the Clinical Research Information Service (CRIS) (number KCT0007124).

Abstract
This multicenter (four institutions), randomized, investigator-masked, parallel-group clinical trial evaluated and compared the efficacy and safety of preservative-free and preserved brimonidine tartrate 0.15% in open-angle glaucoma and ocular hypertension. Sixty eyes of 60 patients with intraocular pressure (IOP) ≥ 15 mmHg diagnosed with open-angle glaucoma or ocular hypertension were randomized to preserved (n = 31) and preservative-free (n = 29) brimonidine groups. The enrolled eyes received brimonidine monotherapy three times daily. Main outcome measures were corneal/conjunctival staining score, ocular surface disease index, patient satisfaction score, drug tolerance, and drug adherence rate 12 weeks post first administration. Secondary outcome measurements included visual acuity, IOP, drug tolerance, tear-film break-up time, hemodynamic changes including blood pressure and heart rates, and ocular adverse events. After 12 weeks, both preserved and preservative-free groups showed similar IOP reduction, corneal and conjunctival staining scores, drug tolerance, and adherence rates. The preservative-free group showed significantly better tear-film break-up time and higher patient satisfaction regarding drug use and management. Systolic and diastolic blood pressure reductions during the 12 weeks were significantly lower in the preserved group than in the preservative-free group. Preservative-free brimonidine tartrate showed comparable efficacy and safety, better corneal tear film stability, and patient satisfaction than preserved brimonidine.

Abstract
PURPOSE To understand the impact of Systane Hydration PF on dryness symptoms and quality of life in digital device users and to determine if participants prefer either the unit-dose or multi-dose dispensing system of Systane Hydration PF. MATERIALS AND METHODS This 2-week, three visit study recruited regular digital device users. Participants were required to score ≤80 on the Impact of Dry Eye on Everyday Life (IDEEL) Quality of Life (QoL) Work domain and between 13 and 32 on the Ocular Surface Disease Index (OSDI) questionnaire. Participants were randomized to either Systane Hydration PF unit-dose or multi-dose for 1 week and switched to the alternative dosing system for the second week. Participations were evaluated by completing the full IDEEL-QoL module and OSDI questionnaire at each visit. Likert surveys were completed to probe dispensing system preferences. RESULTS Thirty participants with a mean ± SD age of 28.6 ± 12.0 years (70% female) were recruited. Participants had significant improvements in all three IDEEL-QoL domains as well as in OSDI scores (all p < 0.0001). Participants had similar preferences for the two dispensing systems, though they were more likely to indicate that they thought that the multi-dose bottle was more environmentally friendly than the unit-dose vials. CONCLUSION Digital device users with dry eye symptoms had meaningful improvements in eye comfort and quality of life scores after being treated with Systane Hydration PF for 2 weeks. Participants did not have a clear dispensing system preference suggesting that the best dispensing system may depend on the patient.

Abstract
PURPOSE OF REVIEW To discuss common reasons for nonadherence and review existing and emerging options to reduce nonadherence with ocular medical therapy and optimize therapeutic outcomes. RECENT FINDINGS Nonadherence can arise from patient-related issues (e.g. physical, cognitive) and healthcare-related issues (e.g. cost, access to care). Multiple strategies have been developed and evaluated to overcome these barriers to adherence. Identifying nonadherence and its cause(s) facilitates the development of strategies to overcome it. SUMMARY Many common causes of nonadherence can be mitigated through a variety of strategies presented.

Abstract
Artificial tears are the mainstay of dry eye disease management, but also have a role in corneal abrasion and wound healing, pain and inflammation management, conjunctivitis, keratitis, contact lens rewetting and removal, and foreign body removal. A systematic review of randomized controlled trials (PROSPERO registration CRD42022369619) comparing the efficacy of artificial tears in patients with dry eye to inform prescribing choices using Web of Science, PubMed and Medline databases identified 64 relevant articles. There is good evidence that artificial tears improve symptoms of dry eye disease within a month of regular use, applied about four times a day, but signs generally take several months to improve. Not all patients with dry eye disease benefit from artificial tears, so if there is no benefit over a month, alternative management should be considered. Combination formulations are more effective than single active ingredient artificial tears. Artificial tears containing polyethylene glycol are more effective than those containing carboxymethylcellulose/carmellose sodium and hydroxypropyl methylcellulose. Those classified as having evaporative dry eye disease, benefit from artificial tears with liposomes, especially of higher concentration. The data available is limited by the definition of dry eye disease applied in published studies being variable, as well as the disease severity examined and compliance with artificial tears being rarely quantified.

Clin Ophthalmol 2022; 16:3841-3849. [PMID: 36438591 PMCID: PMC9698338 DOI: 10.2147/opth.s387111] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/30/2022] [Accepted: 11/10/2022] [Indexed: 03/23/2024] Open
Abstract
PURPOSE To compare OTX-DED, an investigational dexamethasone intracanalicular insert, to loteprednol 0.5% suspension applied QID for 28 days as treatments for acute exacerbations of dry eye disease in terms of patient symptoms, corneal staining, tear breakup time (TBUT), and ocular redness. METHODS Fifty patients with an acute exacerbation of dry eye with at least grade 1 corneal staining were randomized to receive treatment and were each evaluated in one eye at baseline, two weeks and four weeks with the standard patient evaluation of eye dryness (SPEED) questionnaire, the Oxford Scale for corneal stain, Schulze Scale for ocular redness, and intraocular pressure (IOP). RESULTS Forty-four patients completed the study. Significant improvement was noted from baseline to both week 2 and 4 for each treatment in SPEED scores, corneal staining, and TBUT. Ocular redness improved significantly from baseline to week 2 for loteprednol and week 4 for both drugs. No significant difference was noted between treatments in any of these evaluations at any time point. Retention (visibility) of the OTX-DED insert was 95% at week 2 and 90% at week 4. IOP rose significantly from baseline to both week 2 and 4 for eyes receiving loteprednol but not for those receiving OTX-DED. CONCLUSION OTX-DED significantly improved on both signs and symptoms of eyes suffering from acute exacerbations of dry eye disease. This improvement was similar to that seen with loteprednol 0.5% suspension, a well-accepted treatment for this condition. IOP did not change significantly in patients with OTX-DED. These findings support the use of this unique intracanalicular insert for the treatment of acute dry eye once this product is approved and available for use.

Abstract
OBJECTIVE The aim of this study was to describe the placement of subpalpebral lavage (SPL) systems in 12 dogs (15 eyes) intolerant of topical ocular medications to assess the suitability, complications encountered and owner perception of use. ANIMALS STUDIED Retrospective review of dogs that underwent SPL placement for treatment of ocular disease at the Ophthalmology Department, University of Bristol Small Animal Hospital between 2017 and 2021. PROCEDURE(S) Data recorded included signalment, history, diagnosis, treatment, reason for SPL placement, uni- or bilateral placement, duration of placement, complications, and outcome. Owner perception was assessed using an online questionnaire. Statistical analysis included McNemar and Wilcoxon signed-ranks tests. RESULTS Twelve dogs (15 eyes) underwent SPL placement. Eleven owners completed the online questionnaire. Corneal ulceration was the most common disease requiring SPL placement (n = 13/15 eyes, 86.7%). Most cases received multimodal topical therapy (n = 9/15 eyes, 60.0%) via SPL. Owners administered medication 6.63 times daily via SPL (range 1-16 applications/day). All dogs requiring ongoing topical medication (n = 8/12, 66.7%) were trained to accept direct administration during SPL treatment. Statistically significant improvements in medication compliance, ease of application, and reduced perceived risk of iatrogenic ocular injury were reported by owners (p-value = .001, .004, and .031 respectively). Minor complications were infrequently reported but an excellent outcome was achieved for all eyes. CONCLUSION Subpalpebral lavage placement provides a practical and safe solution for the provision of frequent multimodal ocular medication when treating patients with a challenging temperament.

Factors associated with adherence to treatment in patients with open angle glaucoma in Sierra Leone, West Africa: patient demographics and questionnaire. Int Ophthalmol 2022; 42:3479-3493. [PMID: 35556205 DOI: 10.1007/s10792-022-02347-w] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/24/2021] [Accepted: 04/18/2022] [Indexed: 10/18/2022]
Abstract
BACKGROUND Glaucoma is a significant cause of blindness worldwide. It is more common, presents earlier and is more aggressive in those of African descent. Non-adherence and poor knowledge of glaucoma is a significant barrier to treatment and has been associated with low health literacy. We aim to establish the factors contributing to late presentation, treatment non-adherence and disease progression in glaucoma patients in Sierra Leone. This will help better understand the challenges eye services face, highlight fields requiring development in patient-clinician interaction and identify areas or specific vulnerable patient groups in which resources should be focused. METHODS Prospective, consecutive recruitment of 120 patients with POAG attending the Lowell and Ruth Gess Eye Hospital and the Connaught Government Teaching Hospital, Freetown, Sierra Leone between February and April 2020. Data were collected from 3 sources: (1) review of clinical notes since first attendance, (2) semi-structured interviews and (3) assessment of study participant's drop instillation technique using a structured checklist. Descriptive statistics was performed for demographic data and other relevant data points. Logistic regression was used for analysis of target variables. RESULTS The average age was 62 years with more males (52.6%). Agricultural workers and informal street traders represented 13.2% of participants' occupation. 25.8% of participants had no formal school, and 47.4% had either a degree or a diploma. This is out of proportion with the general population and may represent a hidden demographic of glaucoma patients. Drop instillation technique was successful in 52% of study participants. Notable responses to the questionnaire were 30% of patients did not know the name of their eye condition and 22% had no knowledge of glaucoma. CONCLUSION Investment in a wide-ranging and robust screening programme and public health campaigns targeting these vulnerable groups and high-risk individuals, for example with a positive family history, alongside improved patient education and staff training is required to improve glaucoma care. Support from government, international organisations and the private sector is required to reduce the economic burden of blindness in Sierra Leone.

Abstract
BACKGROUND Considerable numbers of individuals present low vision, blindness, illiteracy and other conditions that could possibly impair their identification of medications, such as eye drops. Through helping these individuals to identify their eye drops, they can achieve greater autonomy. Misidentification can be avoided through use of multisensory sleeves that can be adapted to most eye drop bottles. Correct use of eye drops is important for preventing progression of diseases like glaucoma that could potentially lead to blindness. OBJECTIVE To develop bottle sleeves to aid in identification of eye drops and then interview a group of possible users to evaluate the acceptance of the solution. DESIGN AND SETTING Cross-sectional survey performed at an ophthalmological clinic in São Paulo (SP), Brazil. METHODS We describe the development of multisensory sleeves to assist in identification of eye drops. To assess the acceptance of this solution, we interviewed 18 patients who were currently using three or more types of eye drops. RESULTS We developed four prototypes for eye drop bottle sleeves and conducted an acceptance test on them. Most of the patients who answered the survey about the sleeves were elderly. Most (95%) reported believing that the sleeves would help reduce the risk of mixing up eye drops with other medications that also dispense drops. They also believed that these would increase their autonomy in using eye drops. CONCLUSION The solution presented was well accepted and may help increase safety in using eye drops through preventing misidentification.

Abstract
Purpose: To evaluate the effects of an educational intervention using an eye drop chart and supplementary education on glaucoma patients’ adherence.Methods: In this multicenter prospective study, medically treated glaucoma patients were educated on the administration of eye drops using an eye drop chart. At the time of recruitment, all of the patients completed a questionnaire on demographic characteristics and adherence. Three months after the initial educational intervention, the patients were randomly divided into two groups: an education group and a control group. The education group received supplementary education. Immediately thereafter and at 6 months, all of the patients completed the questionnaire on adherence again. Changes in instillation behavior, the relationship between the adherence score and demographic characteristics, and factors contributing to an improvement in adherence and intraocular pressure were then analyzed.Results: The adherence scores were significantly higher in patients with fewer medications, a higher annual income and higher educational level, and an urban residence (p = 0.038, p = 0.033, p = 0.041 and p = 0.047, respectively). Education on the administration of eye drops and use of the eye drop chart improved adherence scores from 23.05 ± 3.52 to 21.30 ± 3.95 (p = 0.021) and significantly reduced the average intraocular pressure from 14.3 ± 2.9 to 12.4 ± 3.1 mmHg (p < 0.001). Working indoors (odds ratio [OR] = 5.47, p = 0.032) and supplementary education at 3 months (OR = 4.53, p = 0.030) were also correlated with improved adherence.Conclusions: An eye drop chart is an effective tool for improving adherence and intraocular pressure control in glaucoma patients. Improvement in adherence was especially notable in patients whose work predominantly involved indoor activity. The effectiveness of the eye drop chart was improved by supplementary education.

Abstract
(1) Background: Eye drops are the most common route of administration for ophthalmic medications. Administering drops can be a major hurdle for patients, potentially resulting in noncompliance and treatment failure. The purpose of this study is to compare the efficacy and safety of two different aids and the conventional bottle for eye drop instillation; (2) Methods: An interventional crossover study involving standard eye drop bottle, Opticare aid and Autodrop aid. The study included healthy subjects without a history of regular eye drop use; (3) Results: Twenty-six subjects were enrolled. Of those subjects, 96% and 92% were able to assemble the eye drop bottle into the Autodrop and the Opticare aids, respectively. Subjective assessment indicated that Autodrop was significantly easier to assemble than Opticare (95% CI: -1.6802 to -0.1659, p = 0.02). When using either aid, there was no contamination of the bottle tip, which occurred in 46% of subjects when no aid was used (p = 0.0005). Fewer drops were expelled when using the conventional bottle as compared to the aids (p = 0.05 compared to Autodrop, p = 0.1 compared to Opticare); (4) Conclusions: Autodrop and Opticare can assist patients with eye drop placement. These aids completely prevented bottle tip contamination, which was frequently observed when the conventional bottle was used alone.

Abstract
PRECIS Patients can be quite amenable to using eye drop instillation aids. We should consider recommending these devices to patients who otherwise struggle with drop instillation and medication adherence. PURPOSE The purpose of this study was to compare patient acceptance of 3 commercially available eye drop instillation aids in a diverse tertiary care population. METHODS In this prospective, randomized controlled study, 39 patients being treated with topical antihypertensives were assigned to Arm A (no intervention) or Arm B (AutoDrop, AutoSqueeze, or SimplyTouch). Subjects in Arm B were instructed to administer their eye drop with the assigned drop aid at every use for ~6 weeks. Satisfaction surveys were administered at 3 and 6 weeks, where patients also reported the number of drops missed. RESULTS Thirty-two of 39 subjects completed study participation and full data analysis. Within this total group, 24 subjects were randomized to drop aids (AutoDrop N=10, AutoSqueeze N=8, SimplyTouch N=6), and 8 were randomized to no drop aid. At the 3 and 6-week timepoints, patients found instillation easier with AutoDrop (70.0%, 60.0%) followed by the AutoSqueeze (62.5%, 75.0%), and lastly SimplyTouch (33.3%, 33.3%). For the AutoSqueeze, the mean number of drops missed with and without the drop aid were significantly different (P=0.015 at 3 wk, P=0.008 at 6 wk). There was no difference in the mean number of drops missed with the AutoDrop and SimplyTouch at either timepoint. CONCLUSIONS For the AutoDrop and AutoSqueeze groups, over 60% of the patients found the devices helpful and would consider using them long-term. Our results suggest that patients would be amenable to using eye drop instillation aids, although more objective data is needed to determine whether these devices would improve medication compliance and clinical outcomes.

Abstract
PRECIS We compared the quality of instillation of topical treatments from single-dose (SGD) or multidose (MTD) containers in glaucoma patients and showed neither a significant difference between the type of container nor a significant relationship to upper limb mobility. PURPOSE To describe and compare the quality of instillation of topical treatments with SGD or MTD containers in glaucoma patients. To assess factors likely to influence instillation, particularly the upper limb mobility. MATERIALS AND METHODS This multicenter, cross-sectional study included open-angle glaucoma patients with the same self-instilled treatment over at least 3 months. Patients were asked to successively self-administer a drop of artificial tears from SGD and MTD containers in front of an observer. The order of instillation (eye and container) was randomized. Correct instillation was defined as the administration of 1 drop in the lower fornix, without any contact between the tip of the device and the ocular surface. The Quick Disabilities of the Arm, Shoulder, and Hand self-questionnaire assessed upper limb mobility. RESULTS A total of 239 eyes from 173 patients were included. For the worst eye group 33% of patients performed correct instillation with MTD versus 32% using SGD (P=1). In the best eye group, 31.7% patients performed a correct instillation with MTD administration versus 27.5% with SGD (P=0.327). Multivariate analysis showed a significant association between an inadequate SGD instillation, old age (P=0.021), the severity of the visual field deficits (P=0.035), and a low quality of life score (P=0.028). No association existed between the Quick Disabilities of the Arm, Shoulder, and Hand score and the quality of instillation. CONCLUSIONS These results suggest that the handling of single-use containers should be practiced by patients and evaluated by physicians, especially for the elderly population and those with advanced glaucoma. No difference in instillation quality was found between SGD and MTD.

Abstract
Contact lenses are ideally suited for sustained ocular drug delivery to bypass the issues associated with eye drop therapy. However, drugs such as bimatoprost loaded by the conventional soaking method show poor drug uptake, high burst release, and altered critical lens properties. In this study, the effect of gold nanoparticles (GNPs) on bimatoprost loading/uptake from the soaking solution and its release kinetics from the lens was investigated. In one method, GNP solutions of varying strength were loaded into the bimatoprost soaking solution (mM-SS batches), and in another method, the GNPs were included in the contact lens matrix during casting (mM-GN-L batches). The GNPs were spherical with average size of 21.1 nm and -20.1 mV zeta potential. The swelling, oxygen permeability, and optical transmittance of the lens were improved compared to those of the lens drug-loaded by the conventional soaking method (SM-L). The mM-GN-L batches showed significant improvement in drug uptake from the soaking solution compared to the SM-L and mM-SS batches. The in vitro studies showed relatively low burst and sustained bimatoprost release up to 72 h compared to 24 h with the SM-L batch. The ability to sustain drug release improved proportionally with an increase in the amount of GNPs in the lens. The presence of GNPs lowered protein adherence. The GNP-laden lenses were deemed safe in ocular irritation and histopathology reports (rabbit model). Further, they showed higher drug retention in the rabbit tear fluid compared to the SM-L lens. In conclusion, the presence of GNPs in contact lenses increased drug uptake from the soaking solution, and improved the in vitro and in vivo release kinetics without affecting the critical properties of the contact lenses for therapeutic application.

Abstract
The key clinical attributes of preserved dorzolamide/timolol fixed combination (DTFC) and the emerging potential of preservative-free (PF) DTFC are reviewed with published evidence and clinical experience. The indications and role of DTFC in current glaucoma management are critically discussed. Preserved DTFC became the first intraocular pressure (IOP)-lowering fixed combination (FC) approved by the US Food and Drug Administration (FDA) and remains one of most commonly used medications worldwide. The pharmacological properties of DTFC reflect those of its two time-tested constituents, i.e., the carbonic anhydrase inhibitor dorzolamide and the non-selective beta-blocker timolol. In regulatory studies DTFC lowers IOP on average by 9 mmHg (32.7%) at peak and by 7.7 mmHg (27%) at trough. In trials DTFC shows equivalence to unfixed concomitant therapy, but in real-life practice it may prove superior owing to enhanced convenience, elimination of the washout effect from the second drop, improved tolerability, and better adherence. PF DTFC became the first PF FC approved, first in unit-dose pipettes, and more recently in a multidose format. Cumulative evidence has confirmed that PF DTFC is at least equivalent in efficacy to preserved DTFC and provides a tangible clinical benefit to patients with glaucoma suffering from ocular surface disease by improving tolerability and adherence. Finally, we identify areas that warrant further investigation with preserved and PF DTFC

Abstract
PURPOSE OF REVIEW Advances in pharmacology offer freedom from topical medical therapy without compromise of anti-inflammatory and antimicrobial coverage in the perioperative period. In this review, we describe the basis for dropless cataract surgery with the goal of improving outcomes and the patient experience. RECENT FINDINGS Phacoemulsification outcomes depend largely on surgeon skill but also on adherence to a complex multidrug regimen of perioperative anti-inflammatory and antimicrobial therapy to prevent sight-threatening complications such as cystoid macular edema or endophthalmitis. Successful administration of this regimen can be limited by noncompliance, difficulty administering eye drops, bioavailability, and side effects, among others. The recent development of sustained-release formulations of dexamethasone - one an intracanalicular insert and the other an intraocular suspension - can provide sustained tapering doses of dexamethasone while reducing or eliminating the need for anti-inflammatory eye drop therapy. Similarly, mounting evidence compellingly demonstrates that intracameral antibiotic use intraoperatively is at least as effective as topical antibiotics in preventing endophthalmitis. SUMMARY Sustained-release dexamethasone coupled with intracameral antibiotics at the time of phacoemulsification can provide antimicrobial and anti-inflammatory prophylaxis without the need for topical eye drop medications. This approach has the potential to improve compliance with therapy, visual acuity outcomes, and the overall patient experience.

Abstract
Oral drug administration provided as solid oral dosage forms (SODF) remains the major route of drug therapy in primary and secondary care. There is clear evidence for a growing number of clinically relevant swallowing issues (e.g., dysphagia) in the older patient population, especially when considering the multimorbid, frail, and polymedicated patients. Swallowing impairments have a negative impact on SODF administration, which leads to poor adherence and inappropriate alterations (e.g., crushing, splitting). Different strategies have been proposed over the years in order to enhance the swallowing experience with SODF, by using conventional administration techniques or applying swallowing aids and devices. Nevertheless, new formulation designs must be considered by implementing a patient centric approach in order to efficiently improve SODF administration by older patient populations. Together with appropriate SODF size reductions, innovative film coating materials that can be applied to SODF and provide swallowing safety and efficacy with little effort being required by the patients are still needed. With that in mind, a literature review was conducted in order to identify the availability of patient centric coating materials claiming to shorten esophageal transit times and improve the overall SODF swallowing experience for older patients. The majority of coating technologies were identified in patent applications, and they mainly included well-known water soluble polymers that are commonly applied into pharmaceutical coatings. Nevertheless, scientific evidence demonstrating the benefits of given SODF coating materials in the concerned patient populations are still very limited. Consequently, the availability for safe, effective, and clinically proven solutions to address the increasing prevalence of swallowing issues in the older patient population is still limited.

Abstract
PURPOSE To develop a mesoporous silica drug delivery system and target drop-free care after cataract surgery with a single subconjunctival injection. SETTING Laboratory. DESIGN Experimental animal study. METHODS Ketorolac was infiltration-loaded into sol-gel mesoporous silica particles encapsulated with poly(allylamine hydrochloride) and poly(sodium 4-styrenesulfonate) using a layer-by-layer adsorption technique (SG-Ket-LBL). The formulation was subjected to an in vitro and in vivo drug release study in addition to ocular toxicology evaluation. RESULTS Thermogravimetric analysis revealed that the drug loading efficiency was 4.4% for the SG-Ket-LBL particles. The in vivo safety study demonstrated that the formulation was well tolerated after subconjunctival injection and aqueous humor pharmacokinetics showed sustained therapeutic drug release for the targeted time window of 6 to 8 weeks. CONCLUSIONS Findings indicated that sol-gel mesoporous silica could be used as a drug carrier for subconjunctival administration. The tested formulation, SG-Ket-LBL, provided therapeutic ketorolac for 6 to 8 weeks, which might be used for a single subconjunctival injection to replace nonsteroidal anti-inflammatory drug eyedrops after cataract surgery.

Abstract
Background Glaucoma treatments are mostly presented in uni-dose or multi-dose format. A certain number of patients with visual acuity and dexterity problems may have problems in instilling eye drops. Aim To assess patient satisfaction and ease of use of a preservative-free glaucoma treatment (dorzolamide/timolol) in a new and innovative patented multi-dose delivery system. Methods Retrospective, international, multicentre, non-interventional study in 788 adult patients using a multi-dose delivery system for at least 28 days. Results Mean patient age was 68.1 ± 12.1 years. Mean duration of multi-dose delivery system use was 132.1 ± 125.1 days; 66.5% of the patients previously used multi-dose and 33.5% uni-dose delivery systems (n = 734); 78.3% of the patients were satisfied or very satisfied with the multi-dose delivery system. A significant majority (all p ≤ 0.045) of patients with a QuickDash® score between [0 to 25[ (66.4%, n = 211) and [50 to 75[ (81.8%, n = 11) rated multi-dose delivery system as easy or very easy to open and significantly more subjects in the [0 to 25[ (72%) score group rated multi-dose delivery system as being better or much better than their previous device (n = 211). Significantly (all p < 0.01) more subjects with available visual acuity results rated multi-dose delivery system as good, better or much better than their previous dispensing device. Conclusion The tested multi-dose delivery system was highly accepted. It is, therefore, suitable for glaucoma patients with decreased visual acuity and/or dexterity problems. Further studies may be necessary to assess the easiness of use of this easy-to-grip delivery system.

Abstract
PURPOSE OF REVIEW Routine prophylaxis for adverse events following cataract surgery is evolving. Prior reliance on topical eyedrop instillation by patients is giving way to surgeon directed injections at the time of cataract surgery. The benefit of this new approach is assured delivery of drugs in standardized doses which should optimize the healing process and reduce the incidence of untoward events with higher confidence. RECENT FINDINGS Adoption rates of intracameral antibiotic injection amongst European and American cataract surgeons is increasing. Techniques to inject periocular corticosteroid for routine inflammation prophylaxis are also in development. In combination with intraoperative pharmacologic dilation, a drop-free modality can be achieved. SUMMARY Intraoperative injections offer the patient and surgeon assured drug delivery and hold promise to avoid the pitfalls of patient adherence, incorrect topical instillation, and topical drop-associated corneal issues.

Improving eye-drop administration skills of patients - A multicenter parallel-group cluster-randomized controlled trial. PLoS One 2019; 14:e0212007.

Abstract
Background Eye-drop administration errors occur in the majority of patients and increase the risk for treatment failure or systemic adverse events. While lacking knowledge is the principal error cause, most patients overestimate their skills and are unaware of often substantial knowledge gaps. Therefore, the impact of including motivational patient education on long-term eye-drop administration skills of patients was investigated. Methods This is a cluster-randomized controlled trial in German community pharmacies. Patient education in both groups comprised observation of the patient during eye-drop administration to identify individual errors, pharmaceutical counseling, and teach-back evaluation of the training. In the intervention group, motivational communication techniques were included to increase error awareness and readiness for patient education. In addition, intervention patients were trained on repeated errors until administration was performed correctly. In contrast, patients in the control group only received feedback on erroneous administration steps without another assessment and reinforced training. Results In total, 152 adult patients were eligible to the study and 91 patients (intervention group N = 46) agreed to participate in a 1-month, 6-month, and 12-month follow-up. Patient education significantly increased the proportion of patients correctly administering eye-drops from 6% (7 out of 56 intervention patients, 1 out of 82 control patients) at baseline to 35% (12 out of 30 intervention patients, 12 out of 39 control patients, p ≤ 0.001) at the 1-month follow-up, and 64% (11 out of 15 intervention patients, 17 out of 29 control patients, p ≤ 0.001) at the 6-month follow-up irrespective of group allocation. In some patients previously resolved errors recurred during follow-up visits. This emphasizes the need for periodical reevaluation of patient administration skills and the provision of prevention strategies besides education. Conclusion Patient education that included demonstration of administration skills and verbal and written counseling on observed errors improved eye-drop administration skills irrespective of the communication technique applied. Whereof, high drop-out rates limited the power to detect a difference between groups. In particular, periodic demonstration of administration skills seemed important for sustainable improvement of administration skills. However, further error prevention strategies such as additional education materials or support by a caregiver may be necessary in some patients.

Abstract
Glaucoma therapy-related ocular surface disease (OSD) is a serious pathology with a broad spectrum of insidious clinical presentations and complex pathogenesis that undermines long-term glaucoma care. Preservatives, especially benzalkonium chloride (BAK), contained in topical intraocular pressure-lowering medications frequently cause or aggravate OSD in glaucoma. Management of these patients is challenging, and to date often empirical due to the scarcity of controlled long-term clinical trials. Most of the available data are extracted from case series and retrospective analysis. Preservative-free prostaglandins and prostaglandin/timolol fixed combinations are novel options developed to remove the harmful impact of preservatives, especially BAK, upon ocular tissues. Based on what is currently known on the value of preservative-free antiglaucoma therapies it is tempting to speculate how these new therapies may affect the future medical management of all glaucoma patients. This article provides a comprehensive and critical review of the current literature on preservative-free prostaglandins and preservative-free prostaglandin/timolol fixed combinations.

Abstract
PURPOSE To assess the efficacy and safety of a sustained-release intracanalicular dexamethasone insert for the treatment of postoperative ocular inflammation and pain in patients having cataract surgery. SETTING Twenty-one United States sites. DESIGN Prospective multicenter randomized parallel-arm double-masked vehicle-controlled phase 3 study. METHODS Patients with planned clear corneal cataract surgery were randomized (1:1) to receive dexamethasone insert or placebo, and the treatment was placed in the canaliculus of the eye immediately after surgery (Day 1). The primary efficacy endpoints were complete absence of anterior chamber cells at Day 14 and complete absence of pain at Day 8. RESULTS The study comprised 438 adult patients (216 in the treatment arm and 222 in the placebo arm). At Day 14, significantly more patients had an absence of anterior chamber cells in the dexamethasone insert arm compared with placebo (52.3% versus 31.1%; P < .0001). At Day 8, significantly more patients had an absence of ocular pain in the dexamethasone insert arm compared with placebo (79.6% versus 61.3%; P < .0001). The dexamethasone insert arm showed no increase compared with placebo in incidence of all adverse events or ocular adverse events. Twice as many placebo patients required rescue therapy, compared with treated patients at Day 14. CONCLUSIONS Both primary endpoints were successfully met. In addition, patients receiving the dexamethasone insert experienced a decrease in inflammation after surgery as early as Day 4 through Day 45, and a decrease in pain as early as one day after surgery (Day 2) through Day 45. The dexamethasone insert was well-tolerated, and the adverse events profile was similar to placebo.

Abstract
Purpose To compare the success rates of eye drop instillation in the sitting position and supine position among Japanese patients with ocular diseases (cataract, glaucoma, or retinal and vitreous diseases). Methods Patients who were hospitalized in Okayama University Hospital for eye surgery were studied. Instillation procedures of each patient in both the sitting and supine positions were recorded using a video camera at the time of instillation. We defined “success” when one drop fell accurately onto the ocular surface at the first attempt. Instillation of two or more drops, drops delivered to a site other than the eye surface, and touching the eyelashes, eyelids, or conjunctiva with the tip of the eye drop bottle were regarded as “failure”. We excluded patients with vision below counting finger. Results One-hundred and two patients (54 males and 58 females, aged 70.2 ± 12.3 years) with ocular disease who were hospitalized for surgery (cataract: 61.8%, glaucoma: 15.7%, retinal and vitreous diseases: 22.5%) were included in this prospective observational study. The mean duration of eye drop use was 3.1 ± 5.2 years. The success rate of eye drop instillation was significantly higher in the supine position than in the sitting position (64.7% vs. 50%, P = 0.0039). The mean age was significantly higher in the failure group than in the success group (74.0 ± 11.5 vs. 67.7 ± 12.4 years, P = 0.0085) for the sitting position, but not significantly different for the supine position (72.3 ± 12.9 vs. 70.1 ± 12.0 years, P = 0.3849). No significant differences in mean duration of drop use, mean corrected VA, and mean spherical equivalent refraction were observed between success and failure groups, for both sitting and supine positions. Conclusions In the present study, the success rate of eye drop instillation was significantly higher when applied in the supine position than in the sitting position.

Abstract
Aim To evaluate eye drop instillation technique and to explore its determinants in glaucoma patients. Methods One hundred and thirteen patients diagnosed with glaucoma and self-administering topical antiglaucoma eye drops for at least 1 month were evaluated. All patients instilled artificial tear solution in one eye as they would do at home. The whole process was evaluated by two study staff. A comprehensive score system associated with eye drop instillation techniques was used to quantify the instillation technique and explore its determinants such as demographic and clinical characteristics. Results Half of the patients (48.67%) finished the administration of eye drop on first attempt.1.7 eye drops were squeezed out on average. 43 patients (37.17%) got contact with ocular surface or adnexa. Only 19.7% patients had eye drop instillation techniques being defined as well. 11 patients (9.7%) had prior instruction regarding using eye drops, while only 4 patients knew to occlude the tear duct by pressing the dacryocyst area. Older age and worse visual acuity were found to be independent risk factors for worse instillation technique. Conclusions Eye drop instillation technique in glaucoma patients deserves great attention from eye care practitioners during their lifelong follow-up, especially those aged older and have worse visual acuity.

Abstract
All the components of the ocular surface and the lacrimal system are affected by aging. Aging induces lacrimal gland fibrosis, Meibomian gland dysfunction, loss of corneal sensitivity, decreased corneal cell density, impairment of immune defences, increased local inflammation associated with hormonal changes, conjunctivochalasis, lid abnormalities, etc. Furthermore, homeostasis of the ocular surface may be altered by various age-related systemic comorbidities and iatrogenic interventions. Altogether, aging is considered the most predominant risk factor for dry eye disease. The increasing knowledge of the pathophysiology of aging of the ocular surface allows for refinement of the management of ocular surface disease in the elderly.

Abstract
PURPOSE OF REVIEW To describe the current state of knowledge regarding glaucoma patients' eye drop technique, interventions attempting to improve eye drop technique, and methods for assessing eye drop technique. RECENT FINDINGS In observational studies, between 18.2 and 80% of patients contaminate their eye drop bottle by touching their eye or face, 11.3-60.6% do not instill exactly one drop, and 6.8-37.3% miss the eye with the drop. Factors significantly associated with poorer technique include older age, lack of instruction on eye drop technique, female sex, arthritis, more severe visual field defect, lack of positive reinforcement to take eye drops, lower educational level, low self-efficacy, and being seen at a clinic rather than a private practice. Among intervention studies, four of five studies using a mechanical device and three of four studies using educational interventions to improve technique showed positive results, but none of the studies were randomized controlled trials. SUMMARY Poor eye drop technique is a significant impediment to achieving good control of intraocular pressure in glaucoma. Both mechanical device interventions and educational interventions offer promise to improve patients' technique, but studies with stronger designs need to be done followed by introduction into clinical practice.

Ocular Drug Delivery Barriers-Role of Nanocarriers in the Treatment of Anterior Segment Ocular Diseases. Pharmaceutics 2018; 10:pharmaceutics10010028.

Abstract
Ocular drug delivery is challenging due to the presence of anatomical and physiological barriers. These barriers can affect drug entry into the eye following multiple routes of administration (e.g., topical, systemic, and injectable). Topical administration in the form of eye drops is preferred for treating anterior segment diseases, as it is convenient and provides local delivery of drugs. Major concerns with topical delivery include poor drug absorption and low bioavailability. To improve the bioavailability of topically administered drugs, novel drug delivery systems are being investigated. Nanocarrier delivery systems demonstrate enhanced drug permeation and prolonged drug release. This review provides an overview of ocular barriers to anterior segment delivery, along with ways to overcome these barriers using nanocarrier systems. The disposition of nanocarriers following topical administration, their safety, toxicity and clinical trials involving nanocarrier systems are also discussed.

Abstract
PURPOSE To evaluate the safety and efficacy of an anterior chamber intracameral dexamethasone drug-delivery suspension (IBI-10090; DEXYCU; Icon Bioscience Inc., Newark, CA) that provides medication for up to 21 days with a single application in treating postoperative inflammation in patients undergoing cataract surgery. DESIGN Prospective, randomized, double-masked, multicenter trial. PARTICIPANTS Patients with preoperative best-corrected visual acuity of 20/30 to 20/200 undergoing unilateral cataract surgery by phacoemulsification were randomized to receive IBI-10090 or placebo. METHODS Three hundred ninety-four patients were randomized 1:2:2 to receive 5-μl injections of placebo or 5-μl injections of 342 or 517 μg IBI-10090 dexamethasone drug delivery suspension injected into the anterior chamber at the conclusion of cataract surgery. Patients were followed for 90 days after surgery. MAIN OUTCOME MEASURES Primary outcome was anterior chamber cell (ACC) clearing (ACC score of 0) in the study eye at postoperative day (POD) 8. Secondary outcome measures were anterior chamber flare and ACC plus flare clearing in the study eye. Ocular and nonocular adverse events were assessed. RESULTS Anterior chamber cell clearing at POD 8 was achieved in 25.0% of eyes in the placebo group and in 63.1% and 66.0% of eyes in the 342- and 517-μg treatment groups, respectively (P < 0.001). Anterior chamber flare clearing at POD 8 was achieved by 63.8% of eyes in the placebo group and in 92.4% and 89.1% of eyes in the 342- and 517-μg IBI-10090 treatment groups, respectively (P < 0.001). Anterior chamber cell plus flare clearing at POD 8 was achieved in 33.8% of eyes receiving placebo and in 63.1% and 67.3% of eyes receiving 342- and 517-μg IBI-10090, respectively (P < 0.001). Adverse events among the 3 groups were similar, and no serious ocular adverse events were reported up to POD 90. CONCLUSIONS The IBI-10090 dexamethasone drug-delivery suspension placed in the anterior chamber after cataract surgery at concentrations of 342 and 517 μg was safe and effective in treating inflammation occurring after cataract surgery and may be an alternative to corticosteroid drop installation in this patient population.

Abstract
Background To investigate the success rate of eye drop instillation in glaucoma patients with visual field defect as well as non-glaucoma volunteers. Factors that may affect the success rate of eye drop instillation were also evaluated. Design A prospective, observational study. Participants Seventy-eight glaucoma patients and 85 non-glaucoma volunteers were recruited in this study. Methods Open angle glaucoma patients with visual field defect as well as non-glaucoma volunteers were asked to video record their procedures of eye drop instillation using a 5-mL plastic bottle of artificial tear solution. Success of eye drop instillation was judged on video based on the first one drop of solution successfully applied on the cornea, by two investigators. Main outcome measures Success rate of eye drop instillation in glaucoma patients and non-glaucoma volunteers. Factors related to success rate of eye drop instillation, such as visual field defect and clinical characteristics, were also analyzed using multivariable logistic regression. Results No significant deference in mean age was observed between two groups (glaucoma: 64.5 ± 14.4 years, non-glaucoma: 60.9 ± 14.1 years, P = 0.1156). Success rate of eye drop instillation was significantly lower (P = 0.0215) in glaucoma patients (30/78; 38.5%) than in non-glaucoma volunteers (48/85; 56.5%). The most frequent reason of instillation failure in glaucoma patients was touching the bulbar conjunctiva, cornea, eyelid or eyelashes with the tip of the bottle (29.5%). Multivariable logistic regression analysis identified lower corrected visual acuity (VA) (≤ 1.0; odds ratio [OR] = 0.20, 95% confidence interval [CI] 0.04–0.93, P = 0.0411), lower mean deviation (MD) (< -12 dB; OR = 0.20, 95% CI 0.05–0.86, P = 0.0307) and visual field defect (VFD) in the inferior hemifield (OR = 0.11, 95% CI 0.02–0.34, P < 0.001) to be significantly related to instillation failure in glaucoma patients. Conclusions Success rate of eye drop instillation was significantly lower in glaucoma patients than in non-glaucoma volunteers. Corrected VA ≤ 1.0, MD < -12 dB and/or VFD in the inferior hemifield may be related to failure of eye drop instillation.

Abstract
Patients play an important role in achieving the desired therapeutic outcomes, as they are frequently responsible for their own medication management. To facilitate drug administration and overcome medication issues, the patients' needs and preferences should be considered in the pharmaceutical drug product design. With the aim to evaluate the current state of evidence for patient appropriateness, acceptability, usability and preference for aspects of this design, a literature search was performed. Comparative clinical studies that assessed such endpoints for different patient populations were included and summarized descriptively. The search identified 45 publications that met the inclusion criteria. A detailed analysis of the studies identified two main areas investigating either packaging design (n=10) or dosage form design (n=35). Studies on packaging design showed preferences for wing top and screw cap openings, push-through blisters and suppositories with slide system. Additionally, child-resistant containers should be avoided concerning specific patient populations. Regarding dosage form design, sprinkles and minitablets were the most preferred in studies involving young patients, while preferences varied considerably depending on route of administration and geographical region in studies with adult patients. Review of the methodology used in the studies revealed that ten studies had used well-defined protocols and observational endpoints to investigate patient appropriateness. Studies focusing on methodology for testing the appropriateness and usability of drug products by patients were not found. In conclusion, more interdisciplinary scientific efforts are required to develop and increase research in understanding patient needs and preferences.

Abstract
Objective. This study aims to evaluate eyedrop self-installation techniques and factors affecting these techniques in glaucoma patients. Methods. Researchers directly observed eyedrop instillation procedures of 66 glaucoma patients. Contact with periocular tissues and instillation onto ocular surface or conjunctival fornices were considered. Correlations of instillation patterns with patient characteristics including age, gender, intraocular pressure, cup-to-disc ratio, visual field loss, and total intake of glaucoma medication and handgrip strength score were searched. Results. The average handgrip strength in the instillation without periocular contact group was 66.4 ± 19.7 kg, while the average handgrip strength score was 55.9 ± 20.9 kg in the instillation with contact group. The difference between the two groups was statistically significant (p = 0.039). No statistically significant correlation was found between handgrip strength and the mean number of glaucoma medications, c/d, intraocular pressure (p > 0.05). Also there was no significant relation between mean handgrip strength score and the severity of the visual field defect (p = 0.191). Conclusion. Patients especially with severe glaucomatous damage should be adequately instructed about the proper techniques for self-instillation of eyedrops and motivated to use a proper technique. Also, it is possible to suggest that patients with a higher handgrip strength, indicating the well-being of general health, may be doing better in properly instilling glaucoma eyedrops.

Abstract
Background: To assess the technique of glaucoma eye drop instillation in patients who have and have not attended glaucoma education sessions. To compare this with their subjective perception of eye drop use and identify factors associated with improved performance. Patients and Methods: An observational study of 55 participants who instill their topical glaucoma medication for more than 1 year. Twenty-five patients attended (A) glaucoma teaching sessions >1 year before the study and were compared to thirty patients who never attended (NA). Patients completed a self-reporting questionnaire. They instilled their eye drop, and the technique was video-recorded digitally and later graded by two masked investigators. The results were analyzed using Fisher's exact test and Chi-square test. Predictors were assessed using logistic regression models. Results: There was no significant difference in overall performance scores between the two groups. Good technique was observed in 16% of (A) group versus 23% (NA) group, (P = 0.498). There was a mismatch between patient's subjective and actual performance. Female gender and higher educational level were found to be predictors of good performance of drop instillation on univariable logistic regression analysis. Conclusion: Glaucoma patients are challenged with eye drop instillation despite receiving education on drop administration. There is a discrepancy between patient's perceptions and observed technique of drop administration.

Abstract
OBJECTIVE To evaluate the effectiveness of a novel mirror-hat drop delivery aid. DESIGN Prospective, observational study. PARTICIPANTS Sixty eyes from 30 subjects with primary open-angle glaucoma or ocular hypertension attending the glaucoma unit at the Toronto Western Hospital. METHODS The mirror-hat device consists of a magnifying mirror attached to a brimmed cap. The aid was provided to subjects who self-administered topical antiglaucoma medications. Drop instillation technique (time taken to instill a drop, number of drops dispensed, drop contact location, and contamination of bottle tip) was evaluated with and without the device. Subjects also completed a survey regarding drop administration and satisfaction with the device. RESULTS Subjects were less likely to contaminate the bottle tip by touching their eye/eyelid when using the device than without the device (13% vs 37%, respectively, p = 0.02). Twenty-six subjects (86.7%) indicated they could see the drop using the device versus 12 (40%) who reported they saw the drop without the device (p = 0.0005). There were no statistically significant differences in any of the other outcomes. No predictive factors were associated with improved drop administration technique while using the device including uncorrected near-visual acuity, lens status, and glaucoma severity. CONCLUSIONS Use of the mirror-hat aid is associated with significantly less bottle-tip contamination and better visualization of the drop than without the device; however, the device did not help to reduce time, number of drops, or accuracy when administering eye drops.
