This study is a retrospective analysis of medical findings of patients treated at the
Department of Ophthalmology, Clinical Hospital Split, Croatia in the period of 1995–
1999. Seventy-three cases of acute closed-angle glaucoma were analyzed and compared
in relation to the meteorological factors – hours of sunshine, air temperature and atmospheric
pressure. No significant statistical correlation was found between the development
of acute closed-angle glaucoma and air temperature, atmospheric pressure and
mean sunshine hours in all months, except in November (z = 2.1; p = 0.03). The mean
daily sunshine hours on the day of the acute closed-angle glaucoma onset were found to
be lower than the mean monthly sunshine hours. An increased incidence of acute closedangle
glaucoma was found in the winter months (2 = 14.4; p < 0.01). Seasonal variations
of the incidence of acute closed-angle glaucoma in Split cannot be directly attributed
to the meteorological factors, although the correlation between acute glaucoma and
sunshine seems to have a slightly inverse ratio
