Refractive error, eye care needs and attitude towards spectacle wearing among older Zanzibari craftswomen and implications for developing women-targeted services: a cross-sectional study

Abstract

BackgroundAged Zanzibari women are in a disadvantaged position, having high demand for near-vision spectacles. Currently, there is no information on the eye health status of craftswomen, which makes planning a women-targeted project to deliver eye health services to older craftswomen in Zanzibar difficult. We assessed the prevalence of vision impairment, refractive error, presbyopia, effective spectacle coverage (distance and near) and attitude towards spectacle wearing among older Zanzibari craftswomen.Methods and analysisThis was a cross-sectional study. Unaided and presenting distance and near vision of craftswomen 35 years and older were assessed at the women’s co-operatives. We determined the number of those with distance vision poorer than 6/12 and their causes (distance-vision impairment), the number of those with near vision poorer than N8 at 40 cm (presbyopia) and the number of those whose distance and/or near-vision needs were met adequately with their habitual spectacles (effective distance and near spectacle coverages). A piloted and validated questionnaire (15 statements) was used to determine their attitude towards spectacle wearing.ResultsIn all, 263 craftswomen participated in the survey (mean age 52.1 years±9.4 years). The prevalence of distance vision impairment among the craftswomen was 29.7% (95% CI 24.2% to 35.6%), the primary cause being uncorrected refractive error (n=51, 65.4%), and none were corrected. The prevalence of presbyopia was 86.6% (95% CI 81.5% to 90.7%, n=231) and the effective near spectacle coverage was 0.99%. The craftswomen showed a positive attitude towards spectacle wearing (strongly agree or agree) based on 12 out of 15 statements.ConclusionThe high burden of vision impairment, uncorrected distance refractive error and presbyopia, and a positive attitude towards spectacle wearing among older craftswomen in Zanzibar indicated the need for women-targeted eye health programmes in low-resource settings.

“…A survey was then carried out to assess the eye health needs and attitudes towards eye health among elderly craftswomen. 27 The survey revealed a significant prevalence of uncorrected presbyopia (86.6%), accompanied by remarkably low spectacle coverage (0.99%). 27 These findings establish a baseline for assessing the impact of spectacle correction.…”

“…Subsequently, a survey among craftswomen in Zanzibar found that the prevalence a high proportion of older craftswomen (29.7%) had vision impairment. 27 More than two-thirds needed either distance or near corrective spectacles and the rest needed further ophthalmological care due to posterior eye diseases. 27 …”
