The impact of glaucoma on quality of life in Ethiopia: a case-control study

A comparative study of vision-related quality of life (VRQoL) among glaucoma and nonglaucoma patients at a tertiary care center of North India

Purpose

Glaucoma influences vision-related quality of life (VRQoL) of an individual in various ways. There are very limited studies on the Indian population and the northern part of India. Therefore, we conducted the present study to evaluate VRQoL in glaucoma patients as well as the association between the severity of glaucoma and VRQoL.

Methods

An institution-based, cross-sectional, analytical study was conducted from August 2022 to October 2022 involving 190 participants (95 glaucoma patients and 95 controls). The glaucoma quality of life-15 (GQL-15) questionnaire was explained in their vernacular language by the interviewer. The scoring was given according to the validated scoring algorithm for the questionnaire.

Results

Mean GQL score in the control group was 19.66 ± 5.5 and in glaucoma cases was 32.8 ± 10.2, whereas the mean score of mild glaucoma cases was 22.3 ± 4.83, moderate glaucoma cases was 36.3 ± 4.09, and severe glaucoma cases was 47.24 ± 3.03. Therefore, as the severity of glaucoma increases, the GQL score also increases, indicating poorer quality of life. Visual field loss was strongly positively correlated (correlation coefficient = 0.759, P < 0.01) with the GQL-15 score, while a weaker positive correlation was found with best corrected visual acuity (BCVA), cup disc ratio, and duration of treatment.

Conclusion

Besides controlling or reducing intraocular pressure (IOP) to the target level, the goal of glaucoma treatment should be to provide an individual with good functional vision to maintain an acceptable quality of life. It would also help in providing patients with the best possible treatment, not only in terms of good vision but also in maintaining or improving their overall quality of life.

Factors associated with delayed first ophthalmological consultation for primary glaucoma: a qualitative interview study

Background

Glaucoma has an insidious onset with non-specific early symptoms, often leading patients to delay in seeking help. However, postponing the first ophthalmological consultation can result in delayed diagnosis and treatment, with adverse effects on vision. This study explored the factors associated with delayed first ophthalmological consultation in patients with primary glaucoma, with the overarching aim of informing measures to reduce delayed consultation and avoid the consequent adverse outcomes.

Methods

We adopted a phenomenological approach. Semi-structured interviews were conducted with patients admitted to a tertiary eye hospital in Tianjin, China, from January 2021 to April 2021. Data were analyzed by Colaizzi's seven-step method.

Results

We identified 46 patients with primary glaucoma who delayed their first ophthalmological consultation for various reasons. There were four major themes and 16 sub-themes. The major themes were as follows: (1) occult symptoms that are difficult to identify; (2) insufficient knowledge and understanding of glaucoma-related risks and harm; (3) perceived difficulties in accessing medical care; and (4) inadequate support system.

Conclusion

In order to avoid patient delay and consequent irreversible damage to the visual field in patients with primary glaucoma, it is essential that medical staff identify symptoms more effectively, change habitual medical behavior of the patients, adopt a medical union model, and promote the use of a social medical support system to address practical difficulties in delivering adequate care.

Vision-Related Quality of Life and Associated Factors Among an Adult Population with Glaucoma Attending a Comprehensive Specialized Hospital, Northwest Ethiopia

Background

Glaucoma is a group of ocular conditions that leads to irreversible blindness. It can affect the vision-related quality of life in many ways. In Ethiopia, limited information is available on how and to what extent the vision-related quality of life of the glaucoma population has been affected.

Objective

This study attempted to assess the vision-related quality of life and associated factors among an adult population with glaucoma attending Felege Hiwot Comprehensive Specialized Hospital, Northwest Ethiopia.

Methods

The cross-sectional study was conducted on the adult population with glaucoma attending Felege Hiwot Comprehensive Specialized Hospital. Systematic random sampling was employed to select 319 study participants. Descriptive and summary statistics were calculated. Simple and multiple linear regressions were performed to determine factors associated with vision-related quality of life. A p-value of <0.05 in multivariable regression was considered statistically significant at a 95% confidence level.

Results

The mean glaucoma quality of life-15 score in this study was 47.85 ± 15.41. Below primary education, primary education, visual acuity of the better eye, visual acuity of the worse eye, and severe glaucoma were significantly associated with the glaucoma quality of life-15 score.

Conclusion and Recommendation

The study observed poorer vision-related quality of life in the glaucoma population than previously reported in Ethiopia and around the globe. The vision-related quality of life was significantly associated with educational status, visual acuity of the better and worse eye, and stage of glaucoma in the better eye. Educating the glaucoma population on the nature of the disease, advice on early presentation, and better-coping strategies for the condition are warranted.

Primary glaucomas in adults: Epidemiology and public health-A review

Glaucoma is a mixed group of optic neuropathies that lead to irreversible visual field loss and blindness if left untreated. It is estimated that 3.5% of the global population aged 40 to 80 years have any glaucoma, being the primary open-angle and the primary angle-closure glaucoma the most prevalent forms. Although the age-standardised prevalence of blindness caused by glaucoma has decreased substantially over the last decades, population growth and ageing impose many challenges in preventing glaucoma-related morbidities on a global level. In addition, difficulties in diagnoses and treatment, along with its chronic and irreversible nature, urge the development and implementation of innovative approaches in confronting the disease. This manuscript reviews recent literature related to the epidemiology of primary glaucomas in adults, the risk factors attributed to the development of the disease, and discuss challenges and potential solutions from a public health perspective.

Determinants of Intraocular Pressure (IOP) of Glaucoma Patients at Felege Hiwot Referral Hospital, Bahir Dar, Ethiopia

Background. Glaucoma is a leading cause of irreversible blindness in the world associated with characteristic damage to the optic nerve and patterns of visual field loss due to retinal ganglion cell degeneration. The main objective of this study was to investigate determinants for the variation of intraocular pressure of glaucoma patients under treatment at Felege Hiwot Referral Hospital, Bahir Dar, Ethiopia. Methods. A retrospective cohort study design was conducted on 328 randomly selected glaucoma patients in the ophthalmology clinic at the hospital under the follow-up period from January 2014 to December 2018. Glaucoma patients who have two and more than two visits in the study period were included in the study, but patients who are attending medications less than two visits were excluded from the study. A linear mixed-effects model for intraocular pressure change was used for data analysis. Result. The estimated coefficient of fixed effect intercept was 25.1829, which indicates that the average IOP of the patients was 25.1829 mmHg at baseline time by excluding all covariates in the model ( $p$ value <0.0001), age ( $\beta$ =0.07, 95%CI 0.03, 0.11), urban residence ( $\beta$  = −1.60, 95%CI −2.84, −0.36), family history of glaucoma ( $\beta$  = 4.90, 95%CI 3.38–6.43), timolol and pilocarpine medication ( $\beta$  = −2.02, 95%CI −4.01, −0.03), cup-disk ratio >0.7 ( $\beta$  = 2.60, 95% CI 1.24–3.96), and follow-up time ( $\beta$  = −0.34, 95%CI −0.47, −0.21) were significantly associated with intraocular pressure of glaucoma patients. Conclusion. The predictor age, residence, family history of glaucoma, type of medication, cup-disk ratio, and follow-up time were significantly associated with the intraocular pressure of glaucoma patients. Therefore, healthcare providers give more attention and prioritize those identified factors and give frequent counseling about reducing intraocular pressure of glaucoma patients.

Quality of life of low vision patients: a systematic review and meta-analysis

OBJECTIVE

Quality of vision plays an important role in everyday living, and low vision (LV) can take a toll on individual's quality of life (QOL). The objective of this paper is to evaluate the impact of LV on QOL and depressive symptoms in LV patients compared with healthy controls.

DESIGN

Systematic review and meta-analysis.

METHODS

Literature was systematically searched to obtain all relevant records. Covidence software was used to conduct the systematic review. Duplicate records were removed, and 2 independent reviewers screened records for relevance. After screening, risk of bias assessment was carried out. Data were extracted and meta-analysis was performed using STATA 15.0. Fixed-effect and random-effect models were computed based on heterogeneity.

RESULTS

In total, 2870 records were retrieved from database and grey literature searches. Twelve articles (35 341 subjects) were included for quantitative analysis. Overall, the QOL of LV patients was significantly lower compared with healthy individuals. Common QOL questionnaires, including 25-item visual function questionnaire (VFQ-25) (standard mean difference [SMD] = 0.91, confidence interval [CI]: [0.42-1.40]), 36-item short form survey (SMD = 0.53, CI: [0.26-0.80]), VFQ-14 (SMD = 0.58, CI: [0.42-0.74]), and visual function QOL questionnaire (SMD = 0.68, CI: [0.54-0.82]), demonstrated a poor QOL in LV patients compared with healthy controls. Additionally, odds of depressive symptoms were significantly greater (odds ratio = 2.25, CI: [1.58-3.21]) in LV patients compared with controls.

CONCLUSION

LV patients demonstrated a poor QOL and higher odds of depressive symptoms compared with healthy controls.
