<p>Study definitions.</p>

Two Rapid Assessments of Avoidable Blindness (RAAB) surveys conducted in Uganda's Karamoja subregion in 2015 and 2023. The data includes 3,727 participants examined in 2015 and 3,159 examined in 2023, tracking changes in blindness prevalence and cataract surgical coverage. The study, authored by Gladys Atto, analyzes trends by gender and highlights disparities in effective surgical outcomes.

Use Cases

• Analyze trends in all-cause blindness prevalence based on survey data from 2015 and 2023.
• Compare Cataract Surgical Coverage (CSC) and effective CSC (eCSC) rates across different visual acuity thresholds.
• Investigate gender disparities in cataract service access and outcomes based on reported male-female eCSC gaps.
• Model changes in visual impairment causes and service coverage over an eight-year period.

Strengths

• Provides longitudinal data from two standardized surveys conducted eight years apart (2015 and 2023).
• Includes specific prevalence figures (e.g., 6.0% blindness in 2015, 4.9% in 2023) and detailed CSC/eCSC percentages.
• Explicitly examines gender-based disparities in effective cataract surgical coverage.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data is geographically limited to the Karamoja subregion of Uganda.
