| Popis: | ObjectivesTo investigate the prevalence of near-vision impairment (NVI) and effective spectacle coverage for near vision in those aged ≥40 years in Khammam and Warangal district in Telangana, India.DesignA population-based cross-sectional study.SettingKhammam and Warangal district in Telangana, India.ParticipantsOf 6000 people enumerated, 5357 were examined (89%). 4526 participants without distance vision impairment were included in the analysis.Main outcome measuresThe study teams visited selected households and conducted eye examinations. NVI was defined as binocular presenting near vision worse than N6. ‘Unmet need’ was deemed to be present if the unaided near vision was worse than N6 and improved to N6 with near correction among the participants who did not have spectacles for near vision. ‘Met need’ was deemed to be present when unaided near vision was worse than N6 but improving to N6 with their spectacles. The ‘undermet need’ was deemed to be present when aided near vision was worse than N6 but improved to N6 with correction. Based on these definitions, e-near-vision coverage (%) is calculated as follows: e-NVC (%)=met need/(met need+undermet need+unmet need) × 100.ResultsThe mean age was 53.5 years (SD: 10.8 years), 2534/4526 (55.8%) were women, 1819/4526 (41.8%) had at least primary school education and 2368/4526 (52.3%) were from the Khammam district. The prevalence of NVI was 55.8% (95% CI 72.5 to 75.1; n=3343). Overall, the e-NVC (%) was 31.8%. It was 40.0% in Khammam and 23.2% in Warangal.ConclusionNVI is common in Khammam and Warangal districts in Telangana with inadequate effective near-vision coverage. Effective service delivery models are needed to reach out and provide services to address NVI to achieve universal eye health coverage in the region. |
