Abstract



Objective: To determine the pattern of ocular disorders among computer users in Enugu. Methods: A cross-sectional survey of computer users was conducted in Enugu metropolis between August and December 2000. 560 subjects were selected by simple random sampling method. Examination methods include use of interviewer-administered structured questionnaire, visual acuity tests for distance and near, external eye examination, tonometry, direct ophthalmoscopy, retinoscopy and measurement of the distance between the operator and the computer. Result: A total of 354(63.2%) females and 206(36.8%) males were recruited for the study. Majority of the subjects (85.6%) were under 34 years of age. Two hundred and eleven (37.7%) out of five hundred and sixty subjects interviewed and examined had ocular disorders. Common ocular disorders seen include refractive errors (55%), presbyopia (16.6%), Pterygium (14.7%), conjunctivitis (6.6%). 7 subjects (1.3%) had monocular blindness with VA<3/60. 37 (3.3%) subjects had low vision with VA < 6/18-3/60. Conclusion: Most of the subjects were young people. Ocular disorders were encountered in computer users. Ocular health status of computer users can be improved through periodic ocular examination and health education.
