Purpose: Many school-going children experience physical, social, and academic challenges due to uncorrected refractive errors. This study aims to uncover the prevalence of spectacle compliance, identify factors that encourage regular use, and explore the barriers that lead to non-compliance.
Methods: A retrospective exploratory study assessed compliance with free spectacles provided through the REACH project after three months of spectacles being dispensed.
Purpose: To identify the main barriers and determinants to cataract surgery as perceived by 50 years and older Nepali people with severe visual impairment & blind due to cataracts.
Methods: This was part of the Rapid Assessment for Avoidable Blindness (RAAB), held in all provinces of Nepal from 2018 to 2021. Cataract blindness was defined as a person having the best-corrected vision, < 6/60 in the better eye, and an unoperated cataract, which was the principal cause of visual disability.
Background: Diabetic retinopathy (DR), a microvascular complication of diabetes mellitus (DM), is a leading cause of vision loss worldwide. There is limited national data to inform about the prevalence of DM and DR and its associated factors, which led to the basis of conducting this survey, which would guide us for the same as part of the Rapid Assessment of Avoidable Blindness (RAAB) survey conducted across Nepal.
Methods: A population-based cross-sectional RAAB survey was conducted using multistage cluster random sampling.
Trachoma.
Lancet
May 2025
Trachoma, the leading infectious cause of blindness worldwide, is one of several neglected tropical diseases targeted by WHO for elimination by 2030. The disease starts in childhood with repeated episodes of conjunctival Chlamydia trachomatis infection. This infection is associated with recurrent conjunctivitis (active trachoma), which, if left untreated, leads to cicatricial trachoma characterised by scarring of the conjunctiva, and potentially in-turned eyelashes (trachomatous trichiasis) in later life.

Methods: This cross-sectional study used multistage stratified sampling to select 2148 individuals from Salyan and Surkhet, following the World Health Organization's Ear and Hearing Survey Handbook.
Results: Among 1946 participants, 38.
Purpose: To determine the prevalence and causes of blindness and vision impairment among people 50 years and older in Nepal.
Methods: We conducted seven provincial-level Rapid Assessment of Avoidable Blindness (RAAB) cross-sectional, population-based surveys between 2018-2021. Provincial prevalence estimates were weighted to give nationally representative estimates.
Tropical Data: Approach and Methodology as Applied to Trachoma Prevalence Surveys.
Ophthalmic Epidemiol
December 2023
Purpose: Population-based prevalence surveys are essential for decision-making on interventions to achieve trachoma elimination as a public health problem. This paper outlines the methodologies of Tropical Data, which supports work to undertake those surveys.
Methods: Tropical Data is a consortium of partners that supports health ministries worldwide to conduct globally standardised prevalence surveys that conform to World Health Organization recommendations.
Gender differences in the surgical management of trachomatous trichiasis: an exploratory analysis of global trachoma survey data, 2015-2019.
Int Health
December 2023
Article Synopsis
- Trachomatous trichiasis (TT) is a painful eye problem that can cause blindness, and women are affected more than men.
- Researchers studied data from 20 African countries to see how men and women are treated for TT and if there are differences.
- The results showed that women are more likely to have complications after surgery and are more likely to refuse surgery, suggesting there are some gender differences in how TT is managed.
Article Synopsis
- Health inequalities can worsen as service coverage expands unless countries use equity-focused strategies to address these disparities.
- The developed model prioritizes disadvantaged groups by collecting sociodemographic data, identifying those left behind, engaging with them for insights, and testing solutions through practical trials.
- This model aims to operationalize equity in service delivery, providing a structured approach for program managers to incorporate equity into their practices, particularly in eye-health programs across several countries.
Article Synopsis
- Cataracts are the top cause of blindness worldwide, and effective cataract surgical coverage (eCSC) is crucial to gauge the success of surgical interventions across different populations.
- The World Health Assembly aims to increase eCSC by 30 percentage points by 2030, prompting the analysis of existing survey data to establish a baseline for this metric.
- Findings show significant disparities in eCSC among countries, with high-income nations having better access and outcomes compared to low-income ones, and men generally experiencing higher eCSC than women.
Background: Attendance rates for eye clinics are low across low- and middle-income countries (LMICs) and exhibit marked sociodemographic inequalities. We aimed to quantify the association between a range of sociodemographic domains and attendance rates from vision screening in programmes launching in Botswana, India, Kenya and Nepal.
Methods: We performed a literature review of international guidance on sociodemographic data collection.
Knowledge, Attitude and Practice Regarding Eye Health and Eye Health Services in Nepal.
J Nepal Health Res Counc
August 2019
Article Synopsis
- The study aimed to evaluate the public's knowledge, attitudes, and practices regarding eye health in various districts of Nepal.
- A survey was conducted with 150 households randomly selected from 100 clusters across 15 districts, utilizing a semi-structured questionnaire analyzed using specific software.
- Results showed a majority of respondents had basic knowledge about eye diseases and highlighted the need for improved education methods tailored to different geographical areas, as well as better awareness of eye health-seeking behaviors.
