Is the season of birth a risk factor in glaucoma?

    Several lines of research suggest that some systemic diseases, often associated with age-related conditions, may present with enhanced prevalences owing to very early influences on human development. This paper describes an analysis of 1264 adult Caucasian patients presenting either with primary open angle or narrow angle/angle closure glaucoma on the one hand, or with age-related cataract on the other. In addition, data on cataracts and primary open angle glaucoma on 254 patients of Caribbean origin and 190 of south east Asian origin were also examined. Patients were classified with respect to sex and season of birth. These variables can play a statistically significant role in the prevalence of glaucoma, which raises the possibility that environmental influences may be involved.
