PURPOSE: To the best of our knowledge, implementation of artificial intelligence (AI)-based vision screening in community health fair settings has not been previously studied. This prospective cohort study explored the incorporation of AI in a community health fair setting to improve access to eyecare. METHODS: Vision screening was implemented during a community health fair event using an AI-based non-mydriatic fundus camera. In addition, a questionnaire was provided to survey the various barriers to eyecare and assess eye health literacy...

PURPOSE: The prevalence of trachomatous inflammation-follicular (TF) in Papua New Guinea (PNG) suggests antibiotic mass drug administration (MDA) is needed to eliminate trachoma as a public health problem but the burden of trichiasis is low. As a result, WHO issued bespoke recommendations for the region. If ≥ 20% of 10-14-year-olds have both any conjunctival scarring (C1 or C2 or C3) and corneal pannus and/or Herbert's pits, MDA should be continued. Equally, if ≥ 5% of that group have both moderate/severe conjunctival scarring (C2 or C3) and corneal pannus and/or Herbert's pits, MDA should be continued...

PURPOSE: Trachoma is endemic in Kenya. Since baseline trachoma surveys in 2004, a concerted programme has been undertaken to reduce the prevalence of disease. Here, we report on trachoma prevalence surveys carried out between 2017 and 2020 after interventions were implemented in some areas for trachoma elimination purposes. METHODS: A total of 48 cross-sectional population-based trachoma prevalence surveys were conducted in 39 evaluation units (EUs; covering 45 subcounties) of Kenya between 2017 and 2020...

PURPOSE: Conjunctivitis is one of the most common ocular conditions in clinical practice. Human adenoviruses have been the common causative agents known to cause epidemic kerato-conjunctivitis (EKC) in India from 1996 to 2019 with a positivity range of 13.8%-65.2%. The current study was initiated to throw light on the distribution of keratoconjunctivitis causing agents across India covering a span of 3 years. METHODS: A total of 709 swabs were collected from patients in viral transport medium (VTM), and real-time PCR was done to identify agents including Adenovirus (HAdV), Enterovirus, HSV, and Chlamydia...

Participants were evaluated to determine the prevalence of bilateral early and late AMD. In cases in which exudative AMD or geographic atrophy (GA) was diagnosed in a single eye, the fellow eye was evaluated to determine the presence and type of late AMD...

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.

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...
