Lighting conditions and perceived visual function in ophthalmic conditions.

To determine the influence of different lighting conditions on perceived visual function in patients of different age, gender, race, and in various ophthalmic diseases. A prospective study. A survey given to patients seen in general ophthalmic and retina clinics. Patients were asked four questions: Is your vision better, worse, or the same in (1) bright light vs dim light, (2) indoors or outdoors, (3) beginning or end of the day, and (4) sunny or cloudy day? Parameters tested were age, race, gender, visual acuity, and a variety of ophthalmic conditions. Multivariable models for each question were fit using multinomial regression. Association was considered significant if p < 0.05. A total of 722 patients were enrolled in the study. Patients with lower vision (LogMAR ≥ 0.3) were more likely to indicate they either had better vision indoors or outdoors compared with better vision patients (LogMAR < 0.1). Patients with pseudophakia were also more likely to indicate they had better vision on a cloudy day (OR = 1.9). White patients had double the odds of selecting bright light compared with others. Males were less likely than females to indicate better vision indoors (OR = 0.62). There were no significant associations with age-related macular degeneration (AMD) in the multivariable model. Most patients did not note any difference in lighting conditions, and although there is explanatory rational for some of the findings in this study, those questions concerning lighting conditions or time of day are not useful for screening of disease. Gender and ethnicity were found to have associations with lighting preferences which needs to be further studied.
