Factors Associated With Health-Related Quality of Life in Medically and Surgically Treated Patients With Glaucoma

Vision-related quality of life in patients with glaucoma before and after trabeculectomy

PURPOSE

To determine vision-related quality of life (VR-QoL) and functional and structural parameters associated with VR-QoL in patients with glaucoma before and 12 months after trabeculectomy.

METHODS

Fifty-eight patients undergoing trabeculectomy were included. Participants completed the 25-item National Eye Institute Visual Function Questionnaire (VFQ-25) prior to and 12 months after trabeculectomy. Functional (visual acuity and visual fields) and structural (ganglion cell layer volume) parameters were evaluated for their association with VR-QoL using multiple linear regression of VFQ-25 subscale scores. Intraocular pressure and the number of glaucoma medications were also included in the analyses.

RESULTS

The VFQ-25 composite score did not change after trabeculectomy (before: 74.9; 12 months: 74.0; p = 0.512). The subscale mental health had a significantly higher score 12 months after trabeculectomy (before: 65.6; 12 months: 71.4; p = 0.017). The VFQ-25 scores for general health (before: 68.5; 12 months: 62.5; p = 0.009) and role difficulties (before: 78.9; 12 months: 53.7; p < 0.001) were significantly lower 12 months after trabeculectomy. No functional or structural parameters were associated with VFQ-25 composite score.

CONCLUSION

Overall, VR-QoL in glaucoma patients was similar before and after trabeculectomy, reflecting the procedure's stabilizing effect on both objective and subjective visual function. The absence of correlations between VR-QoL and clinical parameters emphasizes the multifaceted nature of VR-QoL and highlights the limitations of depending solely on objective clinical metrics to evaluate patients' subjective experiences. Using both objective measures and VR-QoL, clinicians can better understand the challenges patients face due to glaucoma and trabeculectomy, potentially leading to better solutions.

Comprehensive assessment of the quality of life of patients with glaucoma when using various methods of treatment

Background. Research and maintenance of an acceptable quality of life is considered to be the main aim of treating chronic incurable disease including glaucoma.The aim. To perform a comprehensive assessment of the quality of life of patients with glaucoma when using various types of surgical and conservative treatment before treatment and 1 month after treatment.Material and methods. We carried out a randomized controlled study which included 229 patients, divided into 2 groups. The first group of patients (133 people) received various types of surgical intervention for glaucoma, consisted of 6 subgroups. They had the following types of surgeries: sinus trabeculectomy with the use of “Glautex” drainage implant; classical sinus trabeculectomy; sinus trabeculectomy with implantation of drainage made of a collagen hemostatic foam; transscleral laser cyclocoagulation of the ciliary body; cataract phacoemulsification in comorbid primary open-angle glaucoma and in primary closed-angle glaucoma. The second group consisted of 96 patients who received conservative treatment; it consisted of 4 subgroups. Patients of subgroups of the 2nd group received various types of conservative therapy against the background of local antihypertensive therapy: complex treatment with the use of vasoprotectives, vitamins, nootropics in a hospital setting; neuroprotective therapy in the form of Retinalamin intramuscular injection. After receiving informed voluntary consent to participate in the study, all patients underwent a comprehensive assessment of the quality of life using universal, specific and psychological questionnaires (SF-36, visual analogue scale, EQ-5D, VFQ-25, GQL-15, VF-14 and HADS) before treatment and 1 month after treatment.Results. The therapy had a positive effect on the quality of life in both groups of patients, however the most pronounced positive dynamics is registered in patients having conservative therapy as compared with those having surgical treatment. The use of valid, reliable questionnaires makes it possible to fully assess the quality of life in glaucoma.

Quality of life in glaucoma patients: Comparison of medical therapy, trabeculectomy, and glaucoma drainage device surgery

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.

[Why trabeculectomy is better than its reputation]

BACKGROUND

Trabeculectomy (TE) remains one of the most frequently performed glaucoma procedures. This surgery enables sufficient reduction of intraocular pressure (IOP) and freedom from using eye drops; however, complication management and time-consuming postoperative care make many ophthalmic surgeons reluctant to include TE in their treatment regimen.

AIM

This review presents the value of TE compared to other forms of filtering and nonfiltering glaucoma surgery.

CONCLUSION

The use of TE is still the most effective method for lowering IOP and in comparison to other forms of glaucoma surgery in most cases enables freedom from eye drops with a subsequent high quality of life. Postoperative complications occur more frequently, but usually heal spontaneously or can be treated adequately and safely by surgery; however, TE requires intensive postoperative care, which should not be neglected. Repeated surgery due to insufficient IOP reduction is less frequent compared to other forms of glaucoma surgery.

Socio-Demographic, lifestyle and eye-related factors associated with quality of life Among people with glaucoma in Serbia

PURPOSE

The purpose of this study was to examine socio-demographic, lifestyle and ophthalmological factors associated with poorer Vision Related Quality of Life (VRQoL) in people with glaucoma.

METHODS

This cross-sectional study included 306 consecutive patients with glaucoma who presented for regular check-ups at the referral center in Belgrade (Serbia) from August 2015 to September 2016. The diagnosis of glaucoma was based on the glaucomatous disc cupping and reproducible visual field impairment on one or both eyes. Quality of life was examined using the validated Glaucoma Quality of Life-15 (GQL-15) and the National Eye Institute Visual Function Questionnaire 25 (NEI VFQ 25).

RESULTS

A series of adjusted linear regression models showed that glaucoma patients with higher educational attainment, who were employed and still driving had better VRQoL. Worse visual acuity and visual field defect, being in later glaucoma stages, having lower intraocular pressure, having two laser interventions as well as having pseudo-exfoliative glaucoma was associated with worse VRQoL. Intake of fewer medications and having had no trabeculectomies on better eye as well as taking less drops per day on worse eye were associated with better VRQoL.

CONCLUSIONS

Several socio-demographic, lifestyle and ocular factors can impact VRQoL in glaucoma patients. Identifying people who are at risk of having worse VRQoL could allow for earlier interventions, such as changes in therapy, undergoing surgery, use of mobility aids etc.

What Glaucoma Patients Are Reading on the Internet: A Systematic Analysis of Online Glaucoma Content

PURPOSE

To systematically assess the content, quality, accuracy, navigability, and readability of the highest ranked online information regarding glaucoma.

DESIGN

Internet-based, cross-sectional study.

PARTICIPANTS

Not applicable.

METHODS

The top 15 Google websites that resulted from the search term "glaucoma" were independently evaluated by 3 glaucoma specialists for content, accuracy (1-4 scale), and navigability (1-3 scale) in March 2020. Content was evaluated by answers to 25 questions regarding information most relevant to glaucoma patients (0-2 scale). Readability (Flesch-Kincaid grade level) and quality (Quality Component Scoring System) were also analyzed.

MAIN OUTCOME MEASURES

Overall content, accuracy, navigability, quality component scores, and reading grade level as described. Additional analyses included type of websites, presence and type of graphic content.

RESULTS

The mean (standard deviation) content score for all websites was 28 (7.6) of 50 possible points (range, 15-45). Inter-rater reliability for content score was good (0.619, 0.746, 0.872 for 3 pairwise comparisons between graders). Mean accuracy score was 9.8 (2.2) of 12 possible points (range, 5-12). Mean navigability score was 7.5 (1.4) of 9 possible points (range, 5-9). Mean reading grade level was 9.3 (1.7) with a range of 7-13 reading grades. Mean quality component score was 7.7 (2.6) of 13 possible points (range, 3-11). Six websites (40%) attempted to visually simulate glaucoma symptoms as tunnel vision (n = 5) and black spots (n = 1). Google rank did not correlate with any of the measures.

CONCLUSIONS

The most readily accessible online information about glaucoma varies in content, quality, accuracy, navigability, and readability. This systematic analysis identifies potential areas of improvement.

Rates of Diplopia in Ahmed FP7, Baerveldt 250, and 350 Glaucoma Patients Compared With Medical Controls

PRECIS

Diplopia was present in ~20% of patients with Ahmed FP7 (FP7) or Baerveldt 350 (B350), compared with 5% to 6% in those with Baerveldt 250 (B250) or controls, suggesting risk of diplopia should be included in preoperative counseling.

PURPOSE

The purpose of this study was to examine the prevalence of diplopia and strabismus in patients with B250, B350, or FP7 glaucoma drainage devices (GDD).

MATERIALS AND METHODS

In this cohort study, glaucoma patients 18 years and above who had received, or would be receiving, a B250, B350, or FP7 GDD, and medically treated controls were consecutively enrolled from August 8, 2017, through July 31, 2019. The Diplopia Questionnaire was administered ≥30 days postoperatively, and upon enrollment to the controls. All diplopic patients underwent orthoptic measurements, which were reviewed by a strabismus specialist. Patients with GDDs in quadrants other than superotemporal, multiple GDDs, or scleral buckles were excluded. Bonferroni correction was applied for pairwise comparisons.

RESULTS

Diplopia was reported in 23/129 (17.8%) GDD patients and 5/99 (5.1%) control patients (P=0.003): 8/35 (22.9%) FP7, 2/32 (6.3%) B250, and 13/62 (21.0%) B350, with significant differences between FP7 versus controls (P=0.014) and B350 versus controls (P=0.011). Diplopia was attributable to GDD in 2 FP7 (5.9%, 95% confidence interval: 0.7-19.2), 0 B250, and 4 B350 (6.5%, 95% confidence interval: 1.7-15.2) patients, without significant differences between the GDDs.

CONCLUSIONS

Patients with the larger (B350) or the higher profile plate (FP7) GDDs were more likely to experience diplopia than controls, and diplopia was attributable to the GDD in ~6% of patients with either a FP7 or a B350 GDD. Since diplopia can affect patients' quality of life, preoperative counseling for GDD surgery, particularly B350 and FP7, should include a discussion of the risk of diplopia.

Occurrence of motility disorders in patients undergoing tube surgery-consecutive, retrospective follow-up case series analysis

BACKGROUND

The two glaucoma drainage devices (GDD) Ahmed and Baerveldt tubes are most commonly used for the treatment of refractory glaucoma. We noticed a significant number of patients with postoperative motility disorders resulting in diplopia. We investigated the occurrence and patterns of postoperative motility disorders overall and between the two GDD tubes using the Hess Screen Test.

METHODS

Retrospective single-center matched case series of 20 patients undergoing Ahmed and 20 patients undergoing Baerveldt tube implantation with a follow-up of at least 1 year. In order to investigate the dynamic of GDD-induced motility disorder over time, from 25 patients, a follow-up examination from two different time periods (3 to 6 months and 12 to 24 months postoperatively) was available. From these 25 patients, 12 had received an Ahmed and 13 a Baerveldt GDD. To compare the different Hess Screen Tests, we developed nine categories of possible emerging motility disorder in the operated eye as a primary endpoint: Motility restriction in up-gaze, in down-gaze, in abduction, in adduction; combined motility disorders in up-gaze and adduction, up-gaze and abduction, down-gaze and adduction, down-gaze and abduction. If there was no motility disorder, this was also separately classified.

RESULTS

Regardless of the used device, Ahmed or Baerveldt, most patients experienced motility disorders to some extent; mainly down-gaze and adduction were affected. However not every motility disorder resulted in diplopia. Although over time a decrease in ocular misalignment was seen, the incidence of diplopia was stable. Nevertheless, only few required therapy. We noted no difference between Ahmed and Baerveldt tube implant devices.

CONCLUSION

Ocular misalignment and restriction of motility is a common finding after GDD. Although not every motility disorder results in diplopia, it is frequent. Therefore, it needs to be taken into consideration in informed consent.

The Effect of Glaucoma on the Quality of Patient’s Life

Glaucoma is a chronic, progressive opticopathy with morphological optic disc changes and visual field disturbances. Visual field disturbances change the patient’s life habits. Medical as well as surgical treatments also disturb patients` activities of daily living. According to this, glaucoma is the disease which affects quality of patient’s life (QQL). Visual field (VF) evaluation is very important in glaucoma disease diagnostic process. Location of the VF defects also have an impact on the QOL. Patient`s daily activities, such as walking, low light condition adaptation, peripheral seeing of the objects, can be affected by glaucoma progression and with VF defects. All social, religious, cultural and traveling events are more difficult for the severe glaucomatous patients (MD<-12dB) in comparison with mild glaucomatous, defined as patients with MD > −6 dB. Every day usage of the local antuglaucomatous therapy disturbs patients’ QOL. The side effects of the eye drops can produce burning sensation, bronchospasm, bradycardia, increased iris pigmentation, increased eyelash length. Also, locally applied therapy provokes ocular surface disease. Benzalkonium chloride provokes destruction of the epithelial cells junction with development of the epitheliopathy and ocular surface disease. Surgically treated glaucoma patients can have disturbed QOL due to ocular surface disease symptoms (foreign body sensation, eye pain, redness, and increased tearing). These symptoms are caused by trabeculectomy and they are correlated with filtering bleb existence.To achieve QOL of the glaucomatous patients, different founded instruments are used. They are classified in: general health, vision specific, and glaucoma specific.

Health-related quality of life in Ahmed FP7, and Baerveldt 250 and 350 patients compared with medical controls

PURPOSE

To compare health-related quality of life (HRQoL) in patients with Ahmed FP7 (FP7), Baerveldt 250 (B250) and Baerveldt 350 (B350) glaucoma drainage device (GDDs), and medically treated controls.

METHODS

This was a prospective cohort study from August 2017 to July 2019. The NEI 25-Item Visual Function Questionnaire (VFQ-25), the Adult Strabismus-20 questionnaire (AS-20) and the Diplopia Questionnaire were conducted ≥30 days postoperatively in GDD patients, on enrolment for controls. Age, sex, treatment type, visual acuity, mean deviation and diplopia were evaluated for association with HRQoL RESULTS: Of the 128 GDD patients enrolled, 35 (27.3%) had FP7, 32 (25.0%) had B250 and 61 (47.7%) had B350. In univariate analysis, decreased HRQoL was associated with younger age (r² range 0.042-0.071), diplopia (r² range 0.039-0.119), GDD treatment (r² range 0.023-0.103), lower visual acuity (r² range 0.021-0.215) and worse mean deviation (r² range 0.029-0.131). All GDD groups had lower HRQoL subscores than the controls. HRQoL scores were lower compared with controls among B350 patients for AS-20 Self-perception subscale, B250 and B350 for Reading and General Function subscales, and FP7 and B350 for VFQ-25 Visual Functioning subscale. There were no significant differences among the GDDs.

CONCLUSIONS

Glaucoma patients with a younger age, diplopia, lower visual acuity, worse mean deviation or a GDD had lower HRQoL. Those with B350 had lower self-perception scores, consistent with previous reports in the literature. This subscale was not diminished in FP7 or B250, so the decreased self-perception scores may be due to greater visibility or awareness of the B350.

Does functional assessment predict everyday visual functioning? Visual function testing and quality of life in mild/moderate age-related macular degeneration

PURPOSE

To prospectively assess correlations between self-reported vision-related quality of life (VR-QoL) and clinical functional assessments in mild/moderate age-related macular degeneration (AMD).

METHODS

Cross-sectional analysis of 64 participants with bilateral mild/moderate AMD. Microperimetry (MP), flicker perimetry (FP), multifocal electroretinogram (mfERG) findings, best-corrected visual acuity (BCVA) and the National Eye Institute Visual-Function Questionnaire-25 (NEI VFQ-25) were assessed for correlation between clinical testing results and NEI VFQ-25 findings.

RESULTS

MP findings in the better eye were weakly correlated with NEI VFQ-25 subscales for colour, general, near and distance vision (p < 0.05 and R² < 0.3 for all). FP findings and mfERG response density were not correlated with any subscale, apart from mfERG ring 1 response density and general health (p < 0.05, R² = 0.41). mfERG latency was weakly correlated with general vision in the better eye in rings 2 and 4 (p < 0.05, R² < 0.2).

CONCLUSION

Functional assessment in mild/moderate AMD is at best, weakly correlated with patient-reported VR-QoL. Despite the growing awareness of the importance of VR-QoL outcomes in improving patient outcomes and satisfaction, surrogate markers of these outcomes remain elusive, and testing of VR-QoL in regular clinical settings remains difficult.

Self-Reported Quality of Life in Patients with Long-Standing Vogt-Koyanagi-Harada Disease

Purpose: To assess health-related (HR-) and vision-related (VR-) quality of life (QoL) in patients with long-standing Vogt-Koyanagi-Harada disease (VKHD).Methods: Cross-sectional study of 49 patients with disease duration ≥12 months followed at Uveitis Service, Universidade de São Paulo, BR, for at least 12 months. HR- and VR-QoL were evaluated using SF-36 and NEI VFQ-25 questionnaires, respectively. Demographic, clinical and visual function data were compared with questionnaire scores.Results: After generalized linear models, lower mensal household income was associated with lower scores in both questionnaires while unemployment was associated with SF-36 questionnaire only. Treatment with peri-/intraocular medications and ocular surgery were associated with higher scores on SF-36 questionnaire. Worse visual acuity (VA), ocular complications and no ocular surgery were related to lower scores on NEI VFQ-25 questionnaire.Conclusions: On HR- and VR-QoL questionnaires difficulties perceived by patients with long-standing VKHD were mainly associated with socio-economic aspects, VA, local treatment and ocular complications.

Beyond intraocular pressure: Optimizing patient-reported outcomes in glaucoma

Glaucoma, an irreversible blinding condition affecting 3-4% adults aged above 40 years worldwide, is set to increase with a rapidly aging global population. Raised intraocular pressure (IOP) is a major risk factor for glaucoma where the treatment paradigm is focused on managing IOP using medications, laser, or surgery regimens. However, notwithstanding IOP and other clinical parameters, patient-reported outcomes, including daily functioning, emotional well-being, symptoms, mobility, and social life, remain the foremost concerns for people being treated for glaucoma. These outcomes are measured using objective patient-centered outcome measures (PCOMs) and subjective patient-reported outcome measures (PROMs). Studies using PCOMs have shown that people with glaucoma have several mobility, navigational and coordination challenges; reading and face recognition deficits; and are slower in adapting to multiple real-world situations when compared to healthy controls. Similarly, studies have consistently demonstrated, using PROMs, that glaucoma substantially and negatively impacts on peoples' self-reported visual functioning, mobility, independence, emotional well-being, self-image, and confidence in healthcare, compared to healthy individuals, particularly in those with late-stage disease undergoing a heavy treatment regimen. The patient-centred effectiveness of current glaucoma treatment paradigms is equivocal due to a lack of well-designed randomized controlled trials; short post-treatment follow-up periods; an inappropriate selection or availability of PROMs; and/or an insensitivity of currently available PROMs to monitor changes especially in patients with newly diagnosed early-stage glaucoma. We provide a comprehensive, albeit non-systematic, critique of the psychometric properties, limitations, and recent advances of currently available glaucoma-specific PCOMs and PROMs. Finally, we propose that item banking and computerized adaptive testing methods can address the multiple limitations of paper-pencil PROMs; customize their administration; and have the potential to improve healthcare outcomes for people with glaucoma.
