Purpose: To determine the prevalence and causes of blindness and visual impairment among adults in Kogi, Nigeria.
Methods: A Rapid assessment of avoidable blindness (RAAB) protocol was used with additional tools measuring disability and household wealth to measure the prevalence of blindness and visual impairment (VI) and associations with sex, disability, wealth, cataract surgical coverage and its effectiveness.
Results: Age- and sex-adjusted all-cause prevalence of bilateral blindness was 3.6% (95%CI 3.0-4.2%), prevalence of blindness among people living with additional, non-visual disabilities was 38.3% (95% CI 29.0-48.6%) compared to 1.6% (95%CI 1.2-2.1%; [Formula: see text] = 771.9, p<0.001) among people without additional disabilities. Cataract was the principal cause of bilateral blindness (55.3%). Cataract surgical coverage (CSC) at visual acuity (VA) 3/60 was 48.0%, higher among men than women (53.7% vs 40.3%); 12.0% among people with non-visual disabilities; 66.9% among people without non-visual disabilities, being higher among people in the wealthiest two quintiles (41.1%) compared to the lowest three (24.3%). Effective Cataract Surgical Coverage at Visual Acuity 6/60 was 31.0%, higher among males (34.9%) than females (25.5%), low among people with additional, non-visual disabilities (1.9%) compared to people with no additional disabilities (46.2%). Effective CDC was higher among people in the wealthiest two quintiles (411%) compared to the poorest three (24.3%). Good surgical outcome (VA>6/18) was seen in 61 eyes (52.6%) increasing to 71 (61.2%) eyes with best correction. Cost was identified as the main barrier to surgery.
Conclusion: Findings suggest there exists inequalities in eye care with women, poorer people and people with disabilities having a lower Cataract Surgical Coverage, thereby, underscoring the importance of eye care programs to address these inequalities.

Objective: Retinopathy of prematurity (ROP) is a leading cause of preventable childhood blindness in preterm infants with low birth weight. The efficacy and safety of prophylactic agents, including vitamin A, propranolol and lipids, in reducing ROP incidence remain unclear. This systematic review and meta-analysis evaluated the effectiveness and safety of these agents in preventing ROP.

Background: Little is known about the impact of PM on people with disabilities. We aimed to explore the association between PM and hospitalization via the emergency department (ED admission) among people with disabilities, together with the attributable ED admission cases and costs.
Methods: We applied a time-stratified case-crossover design adjusting ozone, holiday, and temperature using seven years (2015-2021) of claim-based data on ED admissions from the Korean National Health Insurance Database.
Aim: Evaluation of screening and treatment of retinopathy of prematurity (ROP) at the Department of Pediatric Ophthalmology.
Material And Methods: Retrospective evaluation of the medical records of premature babies, born in the period 2012-2022 and treated at the Neonatology Department and the Neonatology ICU at the University Hospital Brno. On average 150 children annually are put forward for screening of ROP.

Background: Diabetic retinopathy (DR) is a common complication of diabetes and the leading cause of visual impairment and blindness. It has a serious impact on the mental and physical health of patients.
Aim: To evaluate the anxiety and depression status of patients with DR, we examined their influencing factors.

Background: (CT), a Gram-negative intracellular bacterium, is differentiated into three biovars associated with distinct clinical syndromes, ranging from trachoma, the world's cause of preventable blindness, to the most common sexually transmitted infection. This variability underscores CT's significant impact on public health, particularly in low-resource settings. In Kenya, where the demographic is predominantly younger, the burden of CT remains poorly understood and potentially underestimated.
