Association between acute glaucoma and the weather and sunspot activity

Abstract

The dates of presentation of 191 cases of acute closed-angle glaucoma which presented at the Birmingham and Midland Eye Hospital between 1971 and 1974 were analysed and the seasonal incidence of acute glaucoma confirmed (P<0.001). These data were compared with meteorological data for air temperature, rainfall, hours of sunshine, atmospheric pressure, cloud amount, terrestrial magnetic field level, and sunspot numbers. A statistically significant direct association (P<0-05) was found with hours of sunshine and an inverse association (P>005) with cloud amount. A statistically significant inverse association (P<0 05) was found with sunspot count, and this assumed high significance (P<0 0005) on consideration of sunspot activity in the preceding period. The literature is reviewed and the significance of these findings discussed.
