Epidemiology of acute angle-closure glaucoma: incidence and seasonal variations

Abstract

126 cases of acute angle-closure glaucoma were encountered in the total population of the Israel Negev region during 12 years. This constitutes an incidence of 4.2/100,000/year in the total population and 11.1/100,000 in the over-30 population. The female:male ratio was 2.1:1 and the most frequently affected age-group was the 51-60 one; when age adjustment was made for the total population, the risk was equally high for all ages above 50. The ethnic origin had no effect on the incidence. A statistically significant preponderance of attacks occurring during summer and winter was found.
