Eye Care Service Use and Its Determinants in Marginalized Communities in Pakistan: The Karachi Marine Fishing Communities Eye and General Health Survey

摘要

Purpose: To examine gender, ethnic, and socioeconomic differences in access to eye care services in marine fishing communities in Karachi, Pakistan.Methods: The Karachi Marine Fishing Communities Eye and General Health Survey was a door-to-door, cross-sectional survey conducted between March 2009 and April 2010 in fishing communities in Keamari, Karachi, located on the coast of the Arabian Sea. Adults aged 50 years living on three islands and in four coastal areas were enrolled. Participants underwent a detailed interview regarding sociodemographics, eye problems and eye care service use, testing of presenting and best-corrected visual acuity with a reduced logMAR chart, and detailed eye examination.Results: A total of 700 people were planned to be included in the study; 638 (91.1%) were interviewed and examined. Most participants were extremely poor and had no formal education. Only 45.3% (95% confidence interval, CI, 41.4-49.2%) of participants reported having had an eye examination in the past; 12.1% (95% CI 9.5-14.6%) and 30.9% (95% CI 27.3-34.5%) had seen an eye doctor within the last year or prior 5 years, respectively. In the multivariable analysis, ethnicity was the strongest independent predictor of eye care service use, followed by self-reported eye problems and diabetes. Ethnic Bengalis were 4.2 times less likely (adjusted odds ratio 0.24, 95% CI 0.15-0.38; p<0.001) to have had an eye examination in the past than Kutchis.Conclusions: Despite a high prevalence of visual impairment and blindness, levels of eye care examinations in fishing communities, especially among ethnic Bengalis, are disappointingly low. Such communities deserve particular attention in Vision 2020 and other national and international strategies and plans.
