title: Statistical study of pseudopapillits vascularis.
abstract: In pseudopapillitis vascularis the male sex is preponderant. There are two peaks of frequency in the male as well as in the female group, although 72% of the cases appear between 51 and 70 years of age. The onset may be sudden or progessive. The most important aetiological factors are diabetes, arterial hypertension and arteriosclerosis. The disease is bilateral in 46% of the cases. The vision is less than 3/10 in 77% of the cases. An improvement of the visual acuity is observed in 52% of the unilateral cases, but only in 15% of the bilateral cases. The treatment is ineffective. The biopsy of the temporal artery shows an obvious arteriosclerosis in more than two-thirds of the cases.
