Abstract
PURPOSE This study evaluates the recent trends in ocular morbidities and vision-related practices in "out-of-school" children in urban slums of Gurugram in North India. METHODS In this observational study, a validated questionnaire was administered to 161 students from two nonformal slum schools. Sociocultural, demographic data, vision-related practices, and visual acuity with subjective refraction of the children were recorded. RESULTS A total of 80 boys and 81 girls (9.17 ± 2.58 years) participated in this study. About 40% of the children were from lower socioeconomic status. The visual acuity recorded for all the children, except three children, was 6/6 in both eyes. One child had a pre-phthisical eye with no light perception, following a childhood trauma, with the other eye having 6/6 vision. Two children had refractive errors (myopia and compound myopic astigmatism), with a best corrected visual acuity (BCVA) of 6/6. Thirteen children (8%) had Bitot's spots and 67 (35.4%) had allergic conjunctivitis. Eight (5%) children complained of dry eye-related symptoms like redness and watering of eyes, while 19 (11.8%) had diffuse headache. Average number of years spent in school for these children was less than 1.7 years (range: 1 month-6 years). Only 10.5% of the children gave the history of watching television more than 30 h/week. Significant association was found between the income of father and use of digital devices in children below 10 years (P = 0.003) and children playing outdoors (P = 0.001). There was a significant association noted for age and use of digital devices (P = 0.037). CONCLUSION The prevalence of refractive errors in "out-of-school" children of urban slum was much less than the national average. Almost one in three children suffered from eye allergies, while 8% children had Bitot's spots. The data about the prevalence of ocular comorbidities in underserved areas like urban slums can be used to update and strategize eye health-care delivery models for out-of-school children.

Abstract
PURPOSE Assessment of central and peripheral contrast sensitivity (CS) in thyroid eye disease (TED) with and without dysthyroid optic neuropathy (DON). METHODS This cross-sectional study enrolled 33 eyes of 18 treatment-naïve TED patients and 18 age- and sex-matched healthy controls for comparative analysis. A detailed ophthalmic examination included visual acuity (VA), intraocular pressure measurement, slit-lamp biomicroscopy, and CS testing (central and four peripheral regions) using Spaeth-Richman Contrast Sensitivity test was done. RESULTS The average age of TED patients was 47.17 ± 13.99 years and a female preponderance was noted (66.66%, n = 12). Twenty-five eyes (75.8%) were diagnosed as TED without DON, while eight eyes (24.2%) had DON. Nine eyes (27.2%) were in the active stage of disease and 29 eyes (87.8%) had proptosis. The difference in mean logMAR visual acuities between TED patients and controls was statistically insignificant (P = 0.189), but a significant difference was noted in central and total CS score (P < 0.001, Wilcoxon-Mann-Whitney test). On CS comparison between DON and non-DON eyes, a significant difference in average scores was noted in central and all peripheral areas (P < 0.05, Wilcoxon-Mann-Whitney test). With increasing clinical activity score, a statistically significant reduction was noted in CS in three out of four peripheral regions (Spearman correlation, P < 0.05). CONCLUSION Visual function compromise can be detected in TED in the presence of intact VA, by testing CS. Peripheral CS deteriorates with increasing inflammation and in DON. Serial monitoring of both central and peripheral CS may help in diagnosing DON early.

Abstract
Background Glaucoma is an optic neuropathy associated with characteristic structural damage to the optic nerve and associated visual dysfunction that may be caused by various pathological processes. A number of pharmacological agents are used to reduce the intraocular pressure (IOP), involving the usage of two or three medications concurrently. Literature is sparse regarding prescription patterns of antiglaucoma drugs, especially regarding variability in public sector vs private sector hospitals. Drug utilization studies can add insight for crafting rational, affordable, and ocular surface friendly prescriptions. Aim This study assessed the prescription pattern in glaucoma patients of a public sector, tertiary care hospital vs a private sector tertiary care hospital. Materials and methods In this retrospective study, pertinent data of diagnosed and labeled glaucoma patients were reviewed. Data collected included demographic details, type of glaucoma, number and nature of drugs prescribed, whether innovator or generic drugs were prescribed, if fixed-drug combinations (FDCs) and preservative-free formulations were prescribed. The prescription patterns between the two sectors were compared, as were the prescription patterns between primary open-angle glaucoma (POAG) and primary angle-closure disease (PACD). Results A total of 336 prescriptions were evaluated (216 from public sector, group I; 120 from private sector, group II). Travoprost 0.004% was the most prescribed antiglaucoma medication in both group I (30.09%) and group II (38.33%). Brimonidine and brinzolamide (14.17%) was the most prescribed combination in group II, while Brimonidine with Timolol (7.87%) in group I. In group I, Timolol and Travoprost were the most prescribed medications for both PACD and POAG. Conclusion This study showed that both public sector as well as private sector tertiary care centers prescribe antiglaucoma medications in tune with current principles of rational drug use. Preservative-free drugs were preferred in both the groups for better adherence.

Abstract
Ocular thermal burns are medical emergencies that require immediate intervention before the standard management protocol, which involves obtaining a detailed history and performing an ophthalmic examination. In this case report, we report the clinical manifestations of ocular burns caused by molten iron and the steps taken for good clinical outcomes. The patient presented with an inferior epithelial defect and limbal and lower lid ischemia at four hours post-injury. Over the course of treatment, due to non-resolving epithelial defect and increased superior lid notching, amniotic membrane transplantation (AMT) and lid repair by pentagon wedge excision were performed. Following AMT, the corneal surface completely healed with residual opacity and neovascularization. Additionally, limbal ischemia was significantly reduced with the restoration of normal lid anatomy. Corneal burns initiate a cascade of inflammatory reactions disrupting the balance between pro- and anti-angiogenic factors, leading to corneal neovascularization. The eyelid damage can lead to necrosis of tissues with eschar formation and eventually quantitative tissue loss. Therefore, timely intervention is the key to the successful management of ocular burns.

Abstract
Effective and safe ophthalmic anesthesia is essential for the delivery of ophthalmic perioperative care both for children and adults. Recent years have seen a major change in form of smaller incisions for most ophthalmic surgical techniques, thus making them less invasive. Additionally, most ophthalmic surgeries are now day-care surgeries at ambulatory surgical centers. The parallel advancements in the field of anesthesiology have boosted the standard of perioperative care. The purpose of this narrative review was to evaluate current trends in anesthetic agents and techniques for ophthalmic anesthesia primarily centered around deep sedation and general anesthesia as per the concerns of practicing anesthesiologists while briefly acquainting with local anesthesia advances.

Abstract
Aim In this study, we analyze the content quality and characteristics of the most viewed search results on various internet platforms related to lifestyle measures for patients with glaucoma. Materials and methods In this internet-based cross-sectional study, we used search keywords "glaucoma," "lifestyle," "glaucoma," and "exercise" on the most popular internet platforms-Google, Facebook, YouTube, and Reddit. The top 30 Google searches about each of the keyword combinations were identified. We also assessed the first 30 videos on YouTube and Facebook Watch, the first 30 Reddit posts and the first 30 Google images about each of the keyword combinations. The quality of content from the platforms was evaluated by three independent reviewers using the well-established Sandvik score, Health on Net (HON) code, and risk score for different uploaders. The quality of content regarding lifestyle measures in glaucoma uploaded by healthcare professionals (HCPs) was further evaluated. Results The established criteria resulted in 48 websites from the Google search engine, 22 videos from YouTube, 37 posts from Reddit, and 28 videos from Facebook Watch, which were included in the final analysis. The mean Sandvik scores were 11.14 ± 1.8 (Google webpages), 10.4 ± 2.19 (YouTube videos), 10.54 ± 2.21 (Facebook Watch), and 4.24 ± 1.18 (Reddit). The mean risk scores were 0.22 ± 0.68 (YouTube videos), 0.18 ± 0.47 (Facebook Watch), and 0.11 ± 0.31 (Reddit). The mean HON code scores were 5.45 ± 1.62 (YouTube), 6.55 ± 1.44 (Google webpages), 5.29 ± 1.04 (Facebook Watch), and 8.27 ± 3.05 (Reddit). The content uploaded by HCPs was primarily from ophthalmologists and had significantly (p < 0.05) higher content quality scores. The majority of the content recommended aerobic exercise as a lifestyle measure in patients with glaucoma as an adjuvant to medical and surgical management. Conclusion The majority of the content regarding lifestyle measures in glaucoma was uploaded by HCPs and had medically accurate and well-referenced information, especially on Google and YouTube. Clinical significance Primary care physicians and ophthalmologists can reliably use social media content to guide recently diagnosed patients about the requisite lifestyle measures.

Abstract
PURPOSE The aim of this study was to evaluate the cases of herpes simplex and zoster ophthalmicus after SARS-CoV-2 vaccination and assess the clinical presentations in patients. METHODS A retrospective analysis of cases reported to the Centers for Disease Control and Prevention (CDC) Vaccine Adverse Event Reporting System (VAERS) between December 11, 2020, and July 1, 2022. Patients diagnosed with herpes simplex ophthalmicus (HSO) and herpes zoster ophthalmicus (HZO) after vaccination with BNT162b2 (Pfizer-BioNTech), mRNA-1273 (Moderna), and Ad26.COV2.S (Janssen) were included in the study. We performed a descriptive analysis of patient demographics, history, and ophthalmic and systemic clinical presentations. The correlations between vaccine type and continuous variables were assessed by the one-way analysis of variance test. In addition, we used the Pearson χ 2 test to assess the association between 3 vaccines and categorical variables. A post hoc analysis was performed between HSO and HZO onset intervals after vaccination, dose, and vaccine type. The 30-day risk analysis was also performed for HSO and HZO onset postvaccination using the reverse Kaplan-Meier analysis. RESULTS A total of 1180 cases of HZO (983, 83.30%) and HSO (180, 15.25%) were reported. The mean age of patients with HZO and HSO was 59.02 ± 19.05 and 52.68 ± 17.83 years, respectively. Most of the cases of HZO (795, 80.87%) and HSO (131, 72.78%) were reported in patients who received BNT162b2. In the cohort, 63.28% and 65.56% diagnosed with HZO and HSO were women. About one third of HZO (36.52%) and HSO (35.56%) cases were reported after the first dose. More than half of the cases of HZO (61.34%) and HSO (64.45%) were reported within the first 2 weeks after vaccination. The estimated crude reporting rate (per million doses) in the United States was 0.25, 0.22, and 0.47 for BNT162b2, mRNA-1273, and Ad26.COV2.S, respectively. The onset interval for HZO was significantly shorter in patients who received BNT162b2 (20.51 ± 56.20 days, P = 0.030) compared with patients who received mRNA-1273 (36.56 ± 108.67 days) and Ad26.COV2.S (39.66 ± 60.15 days) vaccines. The 30-day risk analysis showed a significantly higher risk of HZO after BNT162b2 than the other 2 vaccines ( P = 0.011). CONCLUSIONS The low crude reporting rate suggests that HZO and HSO after SARS-CoV-2 vaccination occur rarely. This study provides insights into the possible temporal association between reported HSO and HZO after SARS-CoV-2 vaccines; however, further investigations are required to delineate the possible underlying immunological mechanisms.

Abstract
PURPOSE The use of video-based social media platforms is increasing among trainee residents, fellows, and practicing ophthalmologists. In this study, we objectively evaluate the quality of Ahmed glaucoma valve (AGV) implantation videos on open access, video-based internet platforms. DESIGN Internet-based cross-sectional study. PARTICIPANTS Not applicable. METHODS In this cross-sectional study, 23 websites publishing medical surgery training video content were queried using the keyword "Ahmed glaucoma valve implantation". MAIN OUTCOME MEASURES The descriptive statistics of video parameters were noted, and the videos were assessed using established scoring systems-Sandvik, Health on the Net Foundation Code of Conduct (HON code), mDISCERN, and Global Quality Score (GQS) scores. Video Quality Score (VQS) was determined based on the 14 steps per the AGV implantation rubric. RESULTS One hundred and nineteen videos were evaluated, and 35 were excluded. The total quality of all 84 videos according to their Sandvik, HON Code, GQS, DISCERN, and VQS scores was 11.79 ± 1.70 (excellent quality), 6.86 ± 0.75 (excellent quality), 3.97 ± 0.93 (good quality), 3.26 ± 0.66 (fair quality) and 11.45 ± 2.67 (good quality), respectively. No significant correlation was found between the descriptive parameters and video quality score. However, no significant correlation was found between the descriptive parameters and video quality score. CONCLUSIONS The objective analysis showed that the video quality ranged from good to excellent. AGV implantation videos were sparse on exclusive ophthalmology surgical video portals. Therefore, more peer-reviewed videos following standardized rubric are needed on open-access surgical video platforms.

Abstract
Purpose To evaluate the outcome of glaucoma drainage device (GDD) insertion of tube through ciliary sulcus (CS) versus anterior chamber (AC) placement in the North Indian population. Methods This retrospective comparative case series included 43 patients in CS group and 24 in AC group, who underwent GDD implantation, from March 2014 to February 2020. The main outcome measures were intraocular pressure (IOP), number of anti-glaucoma medications, best corrected visual acuity (BCVA), and complications. Results Sixty-seven eyes of 66 patients were included in study with mean follow-up of 25.04 months (range, 12-69 months) in the CS group and 17.4 months (range, 13-28 months) in the AC group. Preoperatively the two groups were similar except for postpenetrating keratoplasty glaucoma (PPKG) and pseudophakic patients, which were higher in the CS group (P < 0.05). Both groups showed statistically insignificant difference in postoperative IOP and BCVA at last follow-up (P = 0.173, P = 0.495, respectively). Postoperative complications were similar, except for corneal decompensation which was significantly higher in the AC group (P = 0.042). Conclusion Our findings suggest that there was no statistically significant difference in mean IOP between the CS and AC groups at the last follow-up. CS placement of tube of GDD appears to be effective and safe technique. However, CS placement of tube resulted in lesser corneal decompensation and thus should be preferred in pseudophakic/aphakic patients, especially PPKG.

Abstract
Introduction This study aimed to assess quality of surgical training videos for management of open globe injury (OGI) on online platforms. Material and Methods Twenty-three websites with surgical training videos were queried using the search keyword “open globe repair.” Video content characteristics and quality assessment scores using Sandvik score, Health on the Net Foundation Code of Conduct (HON code), mDISCERN scoring, and global quality score (GQS) were recorded. To evaluate the relevance of the surgical videos to the surgical procedure, steps were analyzed as per the Ophthalmology Surgical Competency Assessment Rubric (OSCAR) for Open Globe Surgical Management. Results One hundred and twenty-three videos were evaluated, and 63 analyzed. Majority videos were uploaded by solitary ophthalmologists (53/63; 84.13%). Mean video quality score (VQS) and GIS scores were 6.55 ± 1.59 and 7.95 ± 1.39, respectively. Mean mDISCERN, GQS, HON Code and Sandvik scores for all the videos were 2.87 ± 1.07, 3.77 ± 1.08, 5.14 ± 1.67, 12.06 ± 1.84, respectively. Videos with background audio and descriptive subtitles had significantly better quality ( p < 0.05). All Quality assessment scores showed a statistically significant ( p < 0.000) positive correlation with each other. On linear regression analysis, number of video likes, comments and views had a significant ( p < 0.05) positive relation with quality of video, whereas video length showed a negative relation with different scores. Conclusion Nearly two-thirds of surgical videos showing OGI repair had good quality assessment scores. Consensus guidelines should be developed to guide uploaders as regards the essential features required for good quality surgical videos using a standardized rubric.

Abstract
Background Ultra-thin Descemet stripping automated endothelial keratoplasty (UT-DSAEK) is a recently developed surgical procedure that has shown promising results for the management of various corneal endothelial diseases. Objectives To evaluate the outcomes of the UT-DSAEK to the Descemet membrane endothelial keratoplasty (DMEK). Design A systematic analysis of the studies comparing UT-DSAEK with DMEK by evaluating one or more outcomes (vision, complications, and post-operative endothelial cell counts) was performed. The meta-analysis was done if two or more studies reported a common outcome. Methods We used PubMed, EMBASE, and SCOPUS databases to identify articles comparing the outcomes of UT-DSAEK with DMEK and performed a meta-analysis using RevMan, version 5.4. Results A total of six studies were included in this review (two randomized clinical trials and four non-randomized comparative studies). Our analysis showed the patients who underwent DMEK cases showed better visual outcomes with a mean difference of 0.06 LogMAR (95% CI: 0.04-0.09) in BCVA, albeit with i 2 of 52% (heterogenous values). The evidence was weak, with the most weightage on retrospective studies. UT-DSAEK showed significantly fewer complications such as graft dislocations, with an odds ratio of 0.25 (95% CI: 0.13-0.48). There was no significant difference in the endothelial cell counts with a mean difference of 86.34 (95%CI: -133.09 to -305.77). Conclusion Although the literature is limited on UT-DSAEK with post-operative visual acuity that could be practically at par with DMEK, lesser complication rates and comparable post-operative endothelial cells could be a suitable alternative to DMEK for corneal endothelial pathologies.

Abstract
The coronavirus disease-19 (COVID-19) infection may remain asymptomatic or may have several different presentations. Although this disease primarily affects the respiratory system, systemic manifestations affecting the gastrointestinal, cardiovascular, neurological, otorhinolaryngologic, and ophthalmic systems have been reported. Ophthalmic signs may be the first and only sign of COVID-19 infection in children. In the current narrative review, we report the ophthalmic manifestations of COVID-19 in the pediatric age cohort. We performed a comprehensive literature search for the publications on ophthalmic manifestations of COVID-19 in children between 1 March 2020 and 1 January 2022 and compiled the ophthalmic manifestations of this entity among the pediatric population. Conjunctivitis is the most common ophthalmic manifestation in children and can develop at any stage of the disease. Ophthalmic manifestations are seen more commonly in children with severe systemic disease. Long-term and indirect consequence of the COVID-19 disease is the rise of myopia among children. Ophthalmic signs may be the first and only sign of COVID-19 infection in children. Pediatricians, as well as ophthalmologists, must keep observing all children with COVID-19 closely for ophthalmic signs.

Abstract
Purpose To compare the quality of life (QoL) in patients with glaucoma on medical therapy and after trabeculectomy and glaucoma drainage device (GDD) using vision, glaucoma, and surgery-specific questionnaires. Methods This cross-sectional study enrolled 30 patients of moderate to severe glaucoma, each in medical, trabeculectomy, and GDD groups. National Eye Institute Visual Function Questionnaire 25 (NEIVFQ-25), Glaucoma Quality of Life (GQL-15), and Surgery Specific Questionnaire (SSQ) were administered, and cumulative scores were compared. Results The mean age of the participants was 58.95 ± 13.6 years with a male preponderance (73.3%, n = 66). The mean scores (SD) in the medical, trabeculectomy, and GDD groups using NEIVFQ-25 were 68.97 (6.98), 72.83 (7.81), and 75.20 (8.77), respectively, those using GQL-15 were 20.63 (6.00), 26.23 (9.12), and 28.43 (7.74), respectively, and for the SSQ, they were 74.33 (8.75) and 72.10 (5.92) in trabeculectomy and GDD groups, respectively. NEIVFQ-25 showed a better QoL in the GDD group compared to the medical group, whereas GQL-15 showed a better QoL in the medical group and comparable QoL in trabeculectomy and GDD. Both these QoL scores correlated to the LogMAR visual acuity. SSQ scores did not show a significant difference in the QoL across both surgical groups. Conclusion NEIVFQ-25 questionnaire scores provided a holistic measure of QoL. GQL-15 assessed the activity limitation and visual disability of the patients but did not take into account the general health and psychological factors influencing the QoL. We did not find a significant difference between trabeculectomy and GDD using the SSQ. For QoL assessment in medically or surgically treated glaucoma, vision-specific and disease-specific questionnaires should always be used in conjunction.

Abstract
BACKGROUND To address the pandemic caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), vaccination efforts were initiated across the globe in December 2020 and are continuing. We report the onset interval and clinical presentations of ocular adverse effects following SARS-CoV-2 vaccination. METHODS For this narrative review, articles in the English language, published between 1 January 2020 to 1 September 2022, were included to formulate a list of the reported ocular adverse effects of different COVID-19 vaccines. RESULTS During this period, ocular adverse effects have been reported with BNT162b2 (Pfizer), mRNA-1273 (Moderna), AZD-1222 (AstraZeneca), and Ad26.COV2.S (Johnson & Johnson) vaccines. Endothelial graft rejection, herpes simplex virus keratitis, herpes zoster ophthalmicus, anterior uveitis, eyelid edema, purpuric rashes, ischemic optic neuropathy, and cranial nerve palsies were the most reported with BNT163b2. Retinal hemorrhages, vascular occlusions, and angle closure glaucoma were the most reported with AZD-1222. Most of the ocular adverse effects reported in the literature had a good to fair prognosis with appropriate management. CONCLUSIONS Evidence regarding the ocular adverse effects does not outweigh the benefits of SARS-CoV-2 vaccination in patients with pre-existing systemic or ophthalmic diseases. This review provides insights into the possible temporal association between reported ocular adverse events and SARS-CoV-2 vaccines; however, further investigations are required to identify the link between potential causality and pathological mechanisms.

Abstract
Purpose To ascertain normative database of contrast sensitivity (CS) using Spaeth/Richman CS test (SPARCS) in the Indian population. Methods This cross-sectional study enrolled 200 healthy individuals, and CS was tested in both eyes of each participant using SPARCS. A detailed ocular examination was done before enrollment to rule out pathologies that may affect CS. A practice test was performed in the right eye (OD), followed by uniocular testing in each eye and a final binocular test. Results Data of 400 eyes of 200 subjects who fulfilled the inclusion criteria was evaluated. The average age of subjects was 46.57 ± 16.77 years (range 21-79 years), with a slight female preponderance (53%, n = 106). A statistically significant decline in average SPARCS scores was noted with increasing age (P < 0.05), ranging from 86.68 (20-29 years age group) to 67.44 (70-79 years age group). Higher scores were noted in binocular testing than uniocular testing (Interclass correlation coefficient [ICC] = 0.83; P < 0.001). Females achieved statistically significant higher total scores in uniocular SPARCS testing (both OD and OS), but there was no significant difference noted between the two genders in binocular testing. Correlation between practice and main tests was statistically Significant with an interclass correlation coefficient of 0.54 (P < 0.001). Conclusion Normative database for SPARCS was established for Indian eyes, with a decreasing trend noted in peripheral as well as central CS scores with increasing age.

Abstract
Background: To counter the rapidly spreading severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), global vaccination efforts were initiated in December 2020. We assess the risk of glaucoma following SARS-CoV-2 vaccination and evaluate its onset interval and clinical presentations in patients. Methods: We performed a retrospective analysis of the glaucoma cases reported to the Vaccine Adverse Event Reporting System (VAERS) database between 16 December 2020, and 30 April 2022. We assessed the crude reporting rate of glaucoma, clinical presentations, onset duration, and associated risk factors. Results: During this period, 161 glaucoma cases were reported, with crude reporting rates (per million doses) of 0.09, 0.06, and 0.07 for BNT162b2, mRNA-1273, and Ad26.COV2.S, respectively. The mean age of the patients was 60.41 ± 17.56 years, and 67.7% were women. More than half (56.6%) of the cases were reported within the first week of vaccination. The cumulative-incidence analysis showed a higher risk of glaucoma in patients who received the BNT162b2 vaccines compared with mRNA-1273 (p = 0.05). Conclusions: The incidence of glaucoma following vaccination with BNT162b2, mRNA-1273, or Ad26.COV2.S is extremely rare. Amongst the patients diagnosed with glaucoma, the onset interval of adverse events was shorter among those who received the BNT162b2 and rAd26.COV2.S vaccines compared with mRNA-1273. Most glaucoma cases were reported within the first week following vaccination in female patients and from the fifth to seventh decade. This study provides insights into the possible temporal association between reported glaucoma events and SARS-CoV-2 vaccines; however, further investigations are required to identify the potential causality link and pathological mechanisms.

Abstract
Tablet based perimetry has the potential to be used as a low-cost, portable method for glaucoma screening. With the advent of tablets with large dynamic luminance range and high spatial resolution, perimetry applications can test visual field locations within the central 30 degrees, just like bowl perimetry. Tablet perimetry has garnered interest in this COVID era as it can be promptly done in the waiting room or even from the comfort of home. The current review focuses on evaluating glaucoma detection sensitivities, diagnostic abilities and correlation of each parameter and examination time of the iPad based perimetry applications with those of HFA.

Abstract
Purpose COVID-19-associated mucormycosis (CAM) was a serious public health problem during the second wave of COVID-19 in India. We planned to analyze public perceptions by sentiment analysis of Twitter data regarding CAM. Methods In this observational study, the application programming interface (API) provided by the Twitter platform was used for extracting real-time conversations by using keywords related to mucormycosis (colloquially known as "black fungus"), from May 3 to August 29, 2021. Lexicon-based sentiment analysis of the tweets was done using the Vader sentiment analysis tool. To identify the overall sentiment of a user on any given topic, an algorithm to label a user "k" based on their sentiments was used. Results A total of 4,01,037 tweets were collected between May 3 and August 29, 2021, and the peak frequency of 1,60,000 tweets was observed from May 17 to May 23, 2021. Positive sentiment tweets constituted a larger share as compared to negative sentiment tweets, with weekly variations. A temporal analysis of the demand for utilities showed that the demand was high in the initial period but decreased with time, which was associated with the availability of resources. Conclusion Sentiment analysis using Twitter data revealed that social media platforms are gaining popularity to express one's emotions during the ongoing COVID-19 pandemic. In our study, time-based assessment of tweets showed a reduction over time in the frequency of negative sentiment tweets. The polarization in the retweet network of users, based on sentiment polarity, showed that the users were well connected, highlighting the fact that such issues bond our society rather than segregating it.

Abstract
Background: Deterioration in peripheral contrast sensitivity (CS) can be an indicator to detect progressive deterioration of visual function in patients with idiopathic intracranial hypertension (IIH). Objectives: The aim of this study was to evaluate the changes in central and peripheral CS and optical coherence tomography (OCT) parameters and in patients with IIH. Design and Methods: In this pilot observational study, data of 20 eyes of 10 ‘treatment-naïve’ IIH patients were analyzed. Detailed ocular examination was performed including CS assessment using both Pelli–Robson (PR) test and Spaeth–Richman Contrast Sensitivity Test (SPARCS) along with the OCT for macular and optic nerve head (ONH) parameters. A comparative analysis was done for CS and OCT parameters from baseline to a follow-up visit > 12 months (range: 18–24 months). Results: The study population had a female preponderance (80%, n = 8), and mean age at diagnosis was 31.9 ± 10.3 years. Mean follow-up period was 21.2 months (range: 15–24 months). At presentation, 6/6 visual acuity was noted in 75% eyes ( n = 15) while all eyes had 6/6 vision at the last follow-up. Average PR score increased from 1.96 ± 0.36 to 2.30 at the last visit (Wilcoxon test: V = 0.0, p ⩽ 0.001) while average SPARCS score (total) increased from 71.85 ± 9.10 to 77.55 ± 6.20 (Paired t-test: t = −2.3, p = 0.035). Change in SPARCS score was significant in average total score ( p = 0.035), and quadrant-wise score in superonasal ( p = 0.014), inferonasal ( p = 0.001), and inferotemporal ( p = 0.021) quadrants. Same trend in SPARCS scores was observed when eyes with and without recurrence were analyzed. Statistically significant difference in retinal nerve fiber layer (RNFL) thickness ( p = 0.007) and macular thickness (MT) in nasal quadrant ( p = 0.006) was seen between the eyes with recurrence and without recurrence. Conclusion: Peripheral CS showed significant difference in all eyes over time. It showed significant change in eyes with recurrence, even in the presence of intact visual acuity and preserved central CS. Changes in RNFL thickness and nasal MT could differentiate eyes which developed recurrence from normal eyes.

Abstract
BACKGROUND Laser peripheral iridotomy (LPI) is the current standard of care for primary angle-closure glaucoma. The existing literature lacks evidence regarding the effects of LPI on contrast sensitivity (CS) after the procedure. OBJECTIVE This study evaluates central and peripheral CS in patients undergoing LPI using the computer-based, Spaeth/Richman Contrast Sensitivity (SPARCS) test. METHODS We performed a pilot, prospective, interventional cohort study including 30 patients of primary angle-closure suspect (PACS) or primary angle closure (PAC) in both eyes. LPI was performed after a detailed history and clinical examination using standard procedure in all eyes. Intraocular pressure (IOP) and CS testing using SPARCS was performed before, 2 weeks and 3 months after LPI. RESULTS Data analyses revealed female predominance (66.67%, 20/30); the mean age of enrolled patients was 49.93 ± 10.43 years, and presenting acuity was 0.02 ± 0.06 (Log of Minimum Angle of Resolution [LogMAR]). The mean vertical cup-to-disc ratio (VCDR), mean deviation (MD in dB) and pattern standard deviation (PSD in dB) were 0.34 ± 0.09, -2.36 ± 1.72 and 2.34 ± 0.81, respectively. There was a statistically significant decrease between the pre- (15.17 ± 3.83 mmHg) and 2 weeks post-LPI (11.70 ± 1.53 mmHg) IOP (p < 0.001). However, CS in the pre- (73.47 ± 9.88) and 3 months post-LPI (75.20 ± 11.98) SPARCS scores did not reveal any statistical difference. The group-wise analysis showed a similar trend between PAC and PACS patients. CONCLUSION LPI does not affect central as well as peripheral CS assessment in patients with the primary angle-closure disease.

Abstract
Purpose: To study the impact of moderate and severe primary open-angle glaucoma (POAG) on the quality of life (QoL) due to activity limitation using glaucoma-specific questionnaires. Methods: This cross-sectional study enrolled 122 participants, 50% (n = 61) being controls and 50% were diagnosed cases of moderate/severe POAG. Three orally administered glaucoma-specific QoL instruments were used: Glaucoma Activity Limitation (GAL-9), Glaucoma Quality of Life (GQL-15), and Viswanathan questionnaires. The questions related to activity limitation were identified and analyzed for each questionnaire separately. Results: The mean age of the participants was 61.04 ± 9.88 years and a majority were males (64.8%, n = 79). The mean scores in controls, moderate glaucoma, and severe POAG patients for GAL-9 questionnaire were 9.77 ± 1.36 (P = 0.44), 13.75 ± 4.76 (P < 0.001), and 23.45 ± 5.62 (P < 0.001), for GQL-15, these were 16.39 ± 2.18 (P = 0.5), 22.75 ± 7.89 (P < 0.001), and 39.34 ± 9.42 (P < 0.001), respectively, while for the Viswanathan questionnaire, they were 9.49 ± 0.94 (P = 0.38), 7.91 ± 1.59 (P < 0.001), and 4.41 ± 2.20 (P < 0.001), respectively. The GQL-15 and GAL-9 questionnaires concluded that activity limitation pertaining to dark adaptation-related tasks affected the QoL the most in moderate as well as severe POAG (P < 0.001). Using the Viswanathan questionnaire, it was observed that the peripheral vision-related activity limitation was most significant for the decrease in QoL in moderate POAG while near vision-related activity limitation affected the QoL the most in severe POAG (P < 0.001). Conclusion: All three questionnaires concluded that the activity limitation due to moderate and severe glaucoma has a negative impact on the QoL. The limitation of the tasks involving dark adaptation/glare and peripheral vision has the most significant impact on the QoL in moderate glaucoma. As the disease progresses to a severe category, the limitation of activities requiring central and near vision causes the most significant worsening in QoL.

Abstract
Although the healing effect of music has been recognized since time immemorial, there has been a renewed interest in its use in modern medicine. This can be attributed to the increasing focus on holistic healing and on the subjective and objective aspects of well-being. In ophthalmology, this has ranged from using music for patients undergoing diagnostic procedures and surgery, as well as for doctors and the operation theatre staff during surgical procedures. Music has proven to be a potent nonpharmacological sedative and anxiolytic, allaying both the pain and stress of surgery. This review aims to explore the available evidence about the role of music as an adjunct for diagnostic and surgical procedures in current ophthalmic practices.

Abstract
Purpose Macular diseases often lead to metamorphopsia, which is traditionally tested using the Amsler grid. This study evaluates a novel method for assessing metamorphopsia, based on the software AMD-A Metamorphopsia Detector, application MacuFix®. Methods In this observational study, the usability of a new smartphone-based testing method to assess metamorphopsia was evaluated in 45 patients experiencing metamorphopsia in at least one eye using the questionnaire “System Usability Score (SUS).” Additionally, the diagnostic adherence of self-monitoring with the Amsler grid was compared to self-monitoring with the novel software MacuFix®. Results The average score of the SUS questionnaire in this study was 76.7 ± 15.5, corresponding to the “good” score on the grading scale. The average interval between two home administered tests was significantly shorter (6 days) when the application was used as compared to using the Amsler grid (19 days). The odds ratio of the frequency of patients using the application to the patients using the home test was 4.
Conclusion MacuFix® application can help in effective home monitoring of macular function as high user satisfaction and increased testing frequency was observed in its use in patients with macular diseases.

Abstract
Purpose Ophthalmology has seen numerous novel uses for smartphones over the years including fundus photography, telemedicine, and operative videography. However, anterior segment photography for assessing and documenting trabeculectomy bleb morphology using a smartphone has not been explored in detail. With the current study, we aim to characterize ideal illumination for the anterior segment smartphone photography in trabeculectomy patients. Methods Thirty status post-trabeculectomy patients were enrolled in this study. Native camera application and FiLMiC pro camera application were used on iPhone X to compare bleb images using yellow and white pen-torches as illumination source. Measured bleb area was compared using ImageJ software from the two apps in different illumination settings by charting boxplots and using one-way ANOVA test using R software to establish consistency. Bland-Altman interoperability for repeatability of bleb-area measurements was analyzed by plotting Bland-Altman plots. Signal-to-noise ratio was calculated using ImageJ for native camera images using slit-lamp camera images as reference. Subjective rating of these images was then performed by two experienced ophthalmologists and kappa coefficient was calculated for inter-operator repeatability. Statistical analysis was performed. Results The measured bleb area from images taken from both apps showed no significant difference, thereby establishing consistency, and Bland-Altman analysis indicated good repeatability and reproducibility. It was noted that SNR was lower for images shot in close illumination as compared to the ones shot in intermediate and distant illumination. Cohen's kappa coefficient was 0.7 for images with distant illumination using white light and 0.65 for images clicked with illumination at an intermediate distance using yellow light, suggesting substantial agreement between the observers. Conclusion Smartphone photography is a reliable tool for morphological assessment trabeculectomy blebs. Optimal illumination helps achieve results free from digital noise and better delineation of specific morphological features. Intermediate illumination and distant illumination provides much better results in terms of high SNR while avoiding overexposure and clipping of highlight information in the images.

Abstract
Purpose: The aim of this study was to determine the correlation between the perimetric outcomes using a free application program of the iPad, 'Visual Fields Easy' (VFE), and Humphrey Visual Field Analyzer (HVFA), in normal as well as eyes with glaucomatous damage of varying severity. Methods: In this prospective, cross-sectional, observational pilot investigation, visual field testing was carried out in 210 eyes of 210 patients (60 Normal, 150 Glaucoma), using suprathreshold VFE application (Version 8) on the iPad and Standard White-on-White using HVFA. Severity of glaucoma was categorized using Hodapp-Anderson-Parrish criteria for visual field defects. The results of the VFE program were compared to the 24-2 SITA FAST HVFA. Results: Data of 210 patients, 100 (47.6%) females, and 110 (52.4%) males, age ranging from 42 to 78 years, Mean 56.64 ± 10.67 years, was analyzed. The Spearman correlation coefficient showed a significant inverse relationship between missed points on the VFE app with MD (S = –0.783) and a parabolic relationship with PSD (S = 0.646) values obtained with the HVFA. As regards missed points, for mild glaucoma, missed points were 37.5, sensitivity was 77.8% and specificity was 52.6%; for moderate glaucoma, missed points were 33.5, sensitivity was 90% and specificity was 48% while for severe glaucoma, missed points were 23, sensitivity was 97% and specificity was 70%. AROC for eyes with mild glaucoma versus normal was 0.419 (95% CI: 0.343-0.495), moderate glaucoma versus normal was 0.705 (95% CI: 0.630-0.780) and severe glaucoma versus normal was 0.857 (95% CI: 0.806-0.908). Conclusion: Suprathreshold perimetry using VFE is not suitable as a rapid screening tool for mass screening of glaucoma. VFE cannot be used as a substitute for HVFA in clinic because of its inability to detect early or moderate glaucoma.

Abstract
INTRODUCTION Hydroxychloroquine (HCQ), is known to cause visual dysfunction during its prolonged course of administration. Optical Coherence Tomography (OCT) and field tests are the commonly used screening tests. Not much is known about the role of contrast sensitivity (CS) as method for early detection of HCQ toxicity. This pilot study was designed to study the change in central and peripheral contrast sensitivity for detecting early signs of HCQ toxicity. DESIGN Prospective study conducted at Government Medical College & Hospital, Chandigarh, India. PARTICIPANTS Twenty eyes of 10 treatment naïve, autoimmune patients. METHODS All patients underwent functional tests, contrast sensitivity tests: Pelli Robson and Spaeth Richman Contrast Sensitivity (SPARCS). Average and quadrant wise SPARCS score; Pelli Robson score and structural parameters viz., macular OCT parameters were compared at baseline, 3- and 6-month post treatment with HCQ. MAIN OUTCOME MEASURES Change in CS using SPARCS and Pelli Robson were recorded at each visit and compared with the baseline. Structural and functional parameters were correlated. RESULTS The average SPARCS scores at baseline, 3-month post HCQ and at 6-month post HCQ were 82.37 ± 8.40, 73.17 ± 9.63 and 70.37 ± 10.08, respectively. Quadrant wise change from first visit to third visit was statistically significant only in superotemporal (p = 0.002), inferotemporal (p = 0.02) and central (p = 0.01) quadrants. There was no correlation between SPARCS and Pelli Robson (S = 0.1454, p = 0.466). Similarly, there was no significant correlation between the structural and functional parameters. CONCLUSIONS HCQ affect the CS by virtue of its action on bipolar and ganglion cells. Decrease in central and peripheral CS as measured by SPARCS can be a sign of early visual dysfunction, hence must be considered as an early indicator of HCQ toxicity.

Abstract
BACKGROUND Idiopathic Intracranial Hypertension (IIH) is a neurological disorder with varied presentation, visual morbidity being the most important one. Literature is sparse as regards the effects of IIH on the visual system in Asians. OBJECTIVE Assessment of visual morbidity and change with treatment in IIH patients in North India through a prospective interventional study. MATERIALS AND METHODS Sixty eyes of newly diagnosed IIH patients were evaluated for functional and structural tests of visual system. Lumbar puncture was performed to establish IIH diagnosis and received oral Carbonic anhydrase inhibitor thereafter. Change in visual function was studied from baseline to 6-month follow-up visit. RESULTS Mean age of participants at presentation was 33.27 ± 10.68 years and majority were females (73.3%). Seventy percent eyes (n = 42) had visual acuity 20/20 at presentation. Average Pelli Robson contrast sensitivity (CS) improved from 1.86 ± 0.34 to 2.11 ± 0.24 (Friedman Test: X2 = 59.2, p ⩽ 0.001) while number of eyes with detectable visual field deficits reduced from 70% to 43.7%. Retinal nerve fibre layer (RNFL) thickness reduced from 176.27 to 114.97 µ (Friedman Test: X2 = 69.3, p ⩽ 0.001). CONCLUSIONS The socio-demographic profile in our study showed higher male incidence than noted in previous studies. Visual function deficits were present in patients, even in those with 20/20 visual acuity. Significant improvement was seen after lumbar puncture and initiation of medical treatment. CS and RNFL thickness showed significant improvement even after 1 month of treatment and can be used for monitoring IIH patients.

Abstract
Background: Fibrous histiocytoma (FH), a mesenchymal tumour, usually have an orbital presentation. Rarely, FH in both benign and malignant forms have been reported at limbus and conjunctiva. Present narrative review was conducted to determine demographic profile, clinical presentation and management options for this rare tumour.Methods: PubMed database was searched to identify articles presenting with fibrous histiocytoma of conjunctiva, cornea and limbus. Data was tabulated for age of presentation, sex, eye involved, area of involvement, if tumor was benign or malignant, management and recurrences.Results: Total of 35 articles were selected, which included 42 cases, of which 27 were benign and 15 malignant. 25 cases showed presence of limbal FH, 12 conjunctival, 4 caruncular and 1 corneal FH. Mean age of presentation was 30.9 years with male preponderance (females-10, males-17) in benign FH while malignant FH presented with mean age of 44.5 years and sex distribution of 7 females and 8 males. 4 cases of benign FH showed recurrence, which required re-excision and immunotherapy, while recurrence in malignant FH was 60%, where 4 needed exenteration, 3 enucleation and 1 expired due to metastasis.Conclusion: FH is one of the rare ocular tumours of eye presenting usually at the limbus and conjunctiva and rarely cornea. Histopathological examination along with immunostaining has a definite role in the diagnosis. Surgical excision with tumour free margins is the corner stone of treatment. Recurrences in benign varieties need re-excision or immunotherapy, while malignant cases need aggressive surgical options like exenteration or enucleation.

Abstract
Purpose: The aim of this study was to evaluate the changing trends in terms of patient load, presenting complaints, surgical procedures and resource utilization in a multispeciality tertiary care hospital after lockdown due to COVID-19. Methods: Retrospective data were collected from Ophthalmology in-patient and emergency services of a government medical college and multispecialty tertiary care hospital in North India. Data pertaining to patient census, presenting complaints, surgical procedures and resource consumption were compared in the 6-month period (March 25 to September 30, 2020) following national lockdown and subsequent gradual unlock to data of same time period last year. Results: A total of 1152 new patients visited Ophthalmology emergency service, whereas 324 sought tele-ophthalmology consultation. Majority were males (61.8%, n = 712), whereas average age of presentation was 34 ± 7.2 years. The number of patients seeking emergency ophthalmic care reduced by 23.9% in the current year, in-patient record reduced by 96.53% and number of surgeries reduced by 98.13%. Tele-ophthalmology services comprised 21.95% of the total patient load. Use of triple layered surgical masks increased by 85.7%, use of disposable gloves increased by 89.5% but interestingly the availability of chlorhexidine hand rub fell by 15.9%, in the current year compared to last year. Conclusion: COVID-19 pandemic and lockdown have reduced the number of patients visiting tertiary health care facility for ophthalmic care. As manpower and resource consumption has increased, smart management is needed to tackle the current scenario efficiently. Tele-ophthalmology must be promoted and we must understand the changing trends to plan for the future accordingly.

Abstract
A 22‑year‑old female presented with bilateral, progressive diminution of vision. Slit‑lamp examination revealed bilateral sectoral corneal edema. Gonioscopy showed broad‑based peripheral anterior synechiae and a membrane obscuring angle structure in both the eyes. On ultrasound biomicroscopy (UBM), a membrane extending from corneal endothelium to anterior iris surface causing traction was seen. Confocal microscopy showed an "epithelium‑like" transformation of the corneal endothelium. This case demonstrates a bilateral Chandler variant of the iridocorneal endothelial (ICE) syndrome where the diagnosis of Chandler's disease was confirmed by confocal microscopy, after the mechanism of secondary angle closure was demonstrated by the UBM.

Abstract
Purpose: To assess changes in the central and peripheral contrast sensitivity in severe primary open-angle glaucoma (POAG) patients using a computer-based Spaeth/Richman contrast sensitivity test (SPARCS) over a period of 24 months. Methods: Our pilot, observational study included 15 patients (30 eyes) with severe POAG. Visual acuity, intraocular pressure, number of anti-glaucoma drugs, visual fields, and SPARCS score were recorded at first visit and at 12 and 24 months. Results: We observed changes in mean deviation (MD) from −19.37 ± 5.04 to −20.63 ± 4.07, mean pattern standard deviation (PSD) from 11.49 ± 2.61 to 11.35 ± 2.01, and mean SPARCS score from 54.97 ± 15.66 to 53.50 ± 16.42. We found no statistically significant difference between visual field parameters and SPARCS scores associated with the number or type of prescribed anti-glaucoma drugs. Spearman’s correlation coefficient of SPARCS at baseline (SPARCS1) versus MD at baseline (MD1) was 0.274 (p = 0.142) and SPARCS1 versus PSD at baseline (PSD1) was −0.163 (p = 0.389). The correlation coefficient between SPARCS at 12 months (SPARCS2) versus MD (MD2) at the same time point was computed to be 0.391 (p = 0.03), whereas SPARCS2 versus PSD at 12 months was −0.212 (p = 0.262). Similarly, we found the coefficient to be 0.336 (p = 0.069) for SPARCS3 (SPARCS at 24 months) versus MD3 (MD at 24 months) and −0.242 (p = 0.197) for SPARCS3 versus PSD3 (PSD at 24 months). Correlation coefficients between SPARCS1/2, SPARCS1/3, MD1/2, MD1/3 PSD1/2, and PSD1/3 were 0.856, 0.865, 0.748, 0.722, 0.497, and 0.562, respectively (p < 0.001). MD changed by 9.46% ± 12.73%, PSD by 0.64% ± 14.03%, and average SPARCS by 3.31% ± 12.73% over 24 months. Conclusion: The data from our study indicate the utilitarian application of SPARCS, an inexpensive and readily available tool for monitoring functional deterioration in cases with advanced glaucomatous damage, especially in resource-poor settings. Furthermore, it is a useful and reliable alternative to the imaging modalities where retinal nerve fiber layer measurement can be erroneous in advanced cases secondary to the floor effect.

Abstract
Background: Idiopathic Intracranial Hypertension (IIH) is a disease of elevated intracranial pressure without any known cause. Visual dysfunction is the major morbidity of this disease but not much is known about the way the contrast sensitivity (CS) function is affected. Objective: This prospective, interventional study attempted to evaluate the change in central and peripheral contrast sensitivity, after treatment in patients diagnosed with IIH. Materials and methods: Twenty eyes of 10 IIH patients underwent an internet based, Spaeth Richman Contrast Sensitivity (SPARCS) test. Average and quadrant wise SPARCS scores were compared at presentation (treatment naïve), 1-month post treatment and 3 months post treatment. Results: The average SPARCS scores pre-treatment, 1-month post-treatment and at 3 months post treatment were 68.8 + 10.16, 74.45 + 11.17 and 75.7 + 10.81 respectively. At 3 months visit, the average SPARCS score was nearly comparable to the average score in normal Indian subjects, observed in a previous study of ours. Quadrant wise change in contrast sensitivity from first visit to third visit was significant in superonasal (p=0.003), inferonasal (p=0.029) and inferotemporal (p= 0.007) quadrants. Discussion: Effect of IIH on visual system is still a relatively unexplored area, especially in the Indians. Not many studies have concentrated on its impact on central as well as peripheral CS. Previous studies have hinted at a possible role of CS as a better indicator of visual dysfunction than other parameters. Conclusions: IIH affects both central and peripheral contrast sensitivity and therapy results in the improvement of contrast deficit. Poor contrast can possibly be explained by relatively more involvement of Magnocellular pathway over the Parvocellular pathway. Abbreviations: IIH = Idiopathic Intracranial Hypertension, CS = Contrast Sensitivity, SPARCS = Spaeth Richman Contrast Sensitivity Test, BMI = Body Mass Index, MC = Magnocellular pathway, PC = Parvocellular pathway

Abstract
Objectives The use of benzalkonium chloride (BAC)-preserved medications is associated with ocular surface disease (OSD) that can negatively affect quality of life (QoL) in glaucoma patients. This study aimed to compare QoL and correlate it with OSD in glaucoma patients receiving BAC-preserved and BAC-free travoprost. Materials and Methods A total of 110 subjects were divided into 3 groups: 40 primary open-angle glaucoma (POAG) patients using BAC-preserved travoprost, 40 POAG patients using BAC-free travoprost, and 30 age-matched controls. All patients were assessed using a single interviewer-administered format of the Ocular Surface Disease index (OSDI) and Glaucoma Quality of Life-15 (GQL-15) questionnaires. Results Mean GQL-15 score in the BAC group was significantly higher than in the BAC-free group (24.71±7.42 vs. 17.58±3.06; p<0.05). The mean difference in GQL-15 scores between controls and the BAC-free group (1.24) was insignificant (p>0.05). There was a strong positive correlation between OSDI scores and GQL-15 scores in all the groups (r values: BAC: 0.63, BAC-free: 0.23, controls: 0.29), with higher OSDI scores (severe OSD) associated with higher GQL-15 scores (worse QoL). Cronbach's alpha was 0.84 for GQL-15 and 0.75 for OSDI. Conclusion BAC-preserved travoprost leads to higher OSDI scores, which correlate strongly with poor QoL scores as compared to BAC-free travoprost. The use of BAC-free formulations should be encouraged to reduce the onset or worsening of OSD and impaired QoL in glaucoma patients.

Abstract
The delivery of ophthalmic drugs is challenging despite easy accessibility via the ocular surface. Topical instillation of eye drops is a relatively easy and most commonly used as a conduit for drug delivery for treating a myriad of ocular morbidities, particularly involving the anterior segment, and has an additional benefit of avoiding the first-pass metabolism while passing through the systemic circulation. The primary challenges of drug administration through traditional methods include-inadequate patient education for proper drug instillation technique, compliance, adherence, and persistence. Various dynamic (choroidal and conjunctival blood flow, lymphatic clearance, and tear dilution) and static (namely, different layers of cornea, sclera, and retina including blood aqueous and blood-retinal barriers) ocular barriers limit drug delivery to the target ocular tissues. The maintenance of the therapeutic drug levels on the ocular surface for a prolonged duration is an added challenge, thus preventing persistent delivery for longer durations. These factors result in inadequate management, leading to poor prognosis in vision loss in as many as 27% of the patients diagnosed with glaucoma. We have reviewed the research and advancements in the development of novel and well-tolerated drug delivery systems with the common goal of overcoming the factors limiting adequate drug delivery to the target tissues in glaucomatous patients with traditional techniques. In the recent past, multiple research groups have successfully designed noninvasive, sustained drug delivery systems, promoting the efficacy as well as the feasibility of delivering topical drugs to the anterior segment.

Abstract
Purpose: To compare a general vision-specific patient-reported outcomes (PRO) instrument, National Eye Institute Visual Function Questionnaire-25 (NEIVFQ-25) with two disease-specific PRO instruments, Glaucoma Quality of Life-15 (GQL-15), and Viswanathan 10 in patients with varying severity of primary open angle glaucoma (POAG). Methods: This hospital-based, prospective study enrolled 140 glaucoma patients. The patients were classified into mild, moderate, and severe glaucoma based on visual field defects. All these patients were administered the three PRO instruments and the results were statistically analyzed. Results: All the three instruments showed high internal consistency (Cronbach's alpha for GQL-15, NEIVFQ-25, and Viswanathan 10 were 0.918, 0.937, and 0.929, respectively) There was a statistically significant difference between patients with mild, moderate, and severe POAG with all instruments (P ≤ 0.001). The instruments correlated well across several parameters especially the peripheral vision and glare/dark adaptation. The disease-specific scales however are simpler and faster to administer. Conclusion: All three instruments were reliable in assessment of mild, moderate, and severe glaucoma. They correlated strongly with each other in most of the related subscales, domains, and questions. NEIVFQ-25 additionally gave information regarding the general, psychological, and social effects of the disease.

Abstract
PURPOSE To evaluate the use of digital devices, reading habits and the prevalence of eyestrain among urban Indian school children, aged 11-17 years. METHODS The study included 576 adolescents attending urban schools who were surveyed regarding their electronic device usage. Additional information on the factors that may have an effect on ocular symptoms was collected. RESULTS Twenty percent of students aged 11 in the study population use digital devices on a daily basis, in comparison with 50% of students aged 17. In addition to using these devices as homework aids, one third of study participants reported using digital devices for reading instead of conventional textbooks. The majority of students preferred sitting on a chair while reading (77%; 445 students), with only 21% (123 students) preferring to lie on the bed and 8 students alternating between chair and bed. There was a significant association between the students who preferred to lie down and those who experienced eyestrain, as reported by a little over one fourth of the student population (27%). Out of 576 students, 18% (103) experienced eyestrain at the end of the day after working on digital devices. CONCLUSIONS The increased use of digital devices by adolescents brings a new challenge of digital eyestrain at an early age. Our study reports the patterns of electronic device usage by school children, evaluates factors associated with eyestrain and highlights the need for further investigation of these issues.

Abstract
Introduction. The topical medications containing benzalkonium chloride (BAK) as preservative is known to induce corneal toxicity and ocular surface disease (OSD) in glaucoma patients. Newer preservatives like SofZia or polyquaternium-1 (Polyquad) have been developed to replace BAK in many medications. The present study aimed at comparing the OSD in glaucoma patients receiving BAK preserved travoprost versus travoprost with polyquad as preservative and controls not receiving any medications. Methods. This prospective, controlled, observational study was conducted on patients of primary open angle glaucoma (POAG) on medications for more than 6 months. The first group comprised of 40 patients receiving BAK preserved travoprost, the second group included 40 patients receiving polyquad preserved travoprost and 30 of control group not receiving any medical treatment. Ocular Surface Disease Index (OSDI) scores using Ocular Surface Disease Index (OSDI) Questionnaire were assessed and compared in all subjects. Results. The mean OSDI score was 29.09 ± 13.45 in BAK group, 12.4 ± 5.085 in polyquad group and 10.93 ± 7.36 in controls. The mean difference in OSDI scores between BAK and polyquad group 16.63 (p < 0.05) and between the BAK and control group was 18.96 (p < 0.05). The mean difference in OSDI scores between the polyquad and control group was 1.53 (p > 0.05). The mean IOP in the BAK group was 19.2 ± 3.5 and in polyquad group was 20.1 ± 4.2. The IOP measured at 12 months of treatment was 13.2 ± 2.1 in BAK group and 12.8 ± 3.3 in polyquad group. The IOP measured at baseline and 12 months showed statistically significant difference in both the groups (p <o.oo1, p=o.ooo, respectively). Conclusions. OSDI scores revealed significantly lesser symptoms in polyquad preserved travoprost when compared to BAK preserved travoprost. The OSDI scores in polyquad group were also comparable to the control group. Hence, for long term glaucoma management polyquad containing travoprost should be preferred over the BAK preserved travoprost.

Abstract
Purpose: To compare the efficacy of AT-TORBI plate haptic toric intraocular lens (IOL) (Carl Zeiss Meditec AG, Jena, Germany) and AcrySof loop haptic toric IOL (Alcon Laboratories, Inc., Fort Worth, TX, USA) for correcting preexisting astigmatism of ≥1 diopters (D) in patients undergoing phacoemulsification and to compare the rotational stability of these two toric IOLs. Methods: In this prospective randomized controlled trial. Forty-two eyes of 42 cataract patients with preexisting astigmatism of 1 D or more were randomized to receive plate haptic toric (AT TORBI) or loop haptic toric (AcrySof) IOLs, with 21 in each group. Postoperative evaluation was done at day 1, 1 week, 1 month, and 3 months. Uncorrected distance visual acuity (UDVA), best corrected visual acuity (VA), and IOL position were noted in both the groups. Results: At 3 months postoperatively, the mean log MAR UDVA was 0.23 ± 0.20 and 0.20 ± 0.13 in Groups I and II, respectively (P = 0.7), the mean residual cylindrical refractive error in plate haptic toric group was 0.40 ± 0.31 D and in loop haptic group was 0.45 ± 0.33 D (P = 0.64). The mean IOL rotation at 3 months follow-up in plate haptic group was found to be 3.52 ± 3.84° and in loop haptic group was 2.05 ± 2.56° (P = 0.25). Conclusion: Both types of toric IOLs were equally efficacious for attaining good uncorrected VA and correcting preexisting astigmatism between 1–5 D. Both of them were rotationally stable at 3 months follow-up.
