PURPOSE: While progress was made towards the Vision 2020: The Right to Sight goals, Ethiopia, Ghana, and Zambia fell short of the recommended cataract surgical rate (CSR) on a national level. Post-operative cataract surgical outcomes are also lower compared to other regions. This study aimed to describe perceived barriers to cataract surgical uptake, factors related to surgeon surgical productivity, and surgical offerings in each of these countries. METHODS: An online survey was sent to ophthalmologists practicing in Ethiopia, Ghana, and Zambia...

PURPOSE: Low- and middle-income countries (LMICs) are underrepresented in ophthalmic research, despite carrying the highest burden of visual impairment. To assess the representation of local authors in global ophthalmic research, this cross-sectional, bibliometric analysis measured the proportion of LMIC-affiliated authorship in LMIC-based ophthalmic research. METHODS: We sampled original, primary research conducted in LMICs and published in 1 of 7 high-impact ophthalmic journals between 2017 and 2021...

PURPOSE: Risk factors (RFs), like 'body mass index (BMI),' 'age,' and 'gender' correlate with Diabetic Retinopathy (DR) diagnosis and have been widely studied. This study examines how these three secondary RFs independently affect the predictive capacity of primary RFs. METHODS: The dataset consisted of four population-based studies on the prevalence of DR and associated RFs in India between 2001 and 2010. An Autoencoder was employed to categorize RFs as primary or secondary...

OBJECTIVE: The relationship between smoking and onset of glaucoma has been inconsistent. However, there is a gap in understanding whether tobacco smoking is linked to a worse visual impairment in different glaucoma subtypes. The objective of this study was to examine the association between smoking behavior and vision-related disability in people who have different glaucoma subtypes. METHODS: A total of 283 people with primary open-angle glaucoma (POAG), primary angle closure glaucoma (PACG), normal tension glaucoma (NTG), and pseudo-exfoliative (PEX) were included in this cross-sectional study...

BACKGROUND: Following baseline surveys in 2013 and 2014, trachoma elimination interventions, including three rounds of azithromycin mass drug administration (MDA), were implemented in 13 woredas (administrative districts) of Gambella Regional State, Ethiopia. We conducted impact surveys to determine if elimination thresholds have been met or if additional interventions are required. METHODS: Cross-sectional population-based surveys were conducted in 13 woredas of Gambella Regional State, combined into five evaluation units (EUs), 6─12 months after their last MDA round...

PURPOSE: Trachoma is an infectious eye disease caused by Chlamydia trachomatis . Infection causes conjunctival inflammation, which can be manifested by the sign known as trachomatous inflammation-follicular (TF). Repeated inflammation leads to eyelid scarring, which in susceptible individuals can cause in-turning of the eyelashes, referred to as trachomatous trichiasis (TT). This article describes 23 population-based surveys conducted in northern and central Benin to determine TF and/or TT prevalence for trachoma elimination purposes...

PURPOSE: The survival outcomes of patients with primary uveal melanomas based on Medicaid status have not been previously discussed in the literature. METHODS: The Surveillance, Epidemiology, and End Results Medicaid database were utilized to identify patients with primary uveal melanomas diagnosed between 2006 and 2013. The Kaplan-Meier method was utilized to construct 5-year survival curves in adult, non-elderly patients. Log-rank testing was used to determine differences in survival rates, and multivariate Cox proportional hazards modeling was utilized to perform adjusted survival analysis...

PURPOSE: To study geographic patterns in ophthalmologist supply and patient demand for services in the United States. METHODS: Google Trends data for the keywords "ophthalmology" and "ophthalmologist" between 2004 and 2019 were queried and normalized to determine relative search volumes (RSV) for each United States state. Ophthalmologist density was calculated by dividing the number of practicing ophthalmologists by the State Census Bureau population estimates. RSV values were divided by ophthalmologist density and normalized to calculate the relative demand index (RDI) for each state...

PURPOSE: Indonesia is a rapidly growing county with over 262 million inhabitants, but among highly populated countries it has one of the lowest concentrations of eye care providers. This study evaluated the cost-effectiveness of a program implemented in South Sulawesi, Indonesia that trained school teachers to conduct vision screenings, organized in-school evaluations by opticians, and provided free eyeglasses to school children with refractive error (RE). METHODS: Schoolteachers across 6 districts in South Sulawesi were trained to screen children with possible RE for subsequent evaluation by opticians...
