Prevalence of presbyopia in a semi-urban population of southwest, Nigeria: a community-based survey.

Uncorrected presbyopia is a major cause of poor near vision in the developing countries. To determine the prevalence and demographic characteristics of presbyopia among adult populations (40 years and above) in a sub-urban population, southwest Nigeria, a population-based cross-sectional study was carried out from April to May 2014. A multi-stage sampling method was used to select eligible respondents. All participants had distance visual acuity assessment done and participants with visual acuity of less than 6/6 were refracted. Near vision was then assessed at 40 cm with distance correction in place if required. Information on near vision was obtained from the participants using interviewer administered questionnaires. Data collected were analysed using SPSS version 22. A total of 440 subjects aged 40 years and above were studied. Prevalence of presbyopia was 75 % and was significantly associated with increasing age. There was higher prevalence of presbyopia among females than males (76.3 % vs. 73.5 %), though not statistically significant. Also prevalence of presbyopia was not significantly associated with educational and occupational status in the study. This study demonstrated a high prevalence of presbyopia. There is need for improved awareness on presbyopia screening and available correction in the local government.
