[Central serous chorioretinitis. Therapy experience over 20 years with and without laser coagulation].

Since 1969, 1,179 eyes with central serous chorioretinopathy have been examined with fluorescein fundus angiography. The classic form with fluorescein leakage (type I) decreased in incidence from 86.4% to 55.4%, while an atypical form with frequent serous pigment epithelial detachment (type II) increased from 12.6% to 33.0%, and the mixed form (type I + II) increased from 1 to 11.6%. In type I with delayed healing laser coagulation of the leakage was performed, which improved the visual acuity from 0.64 to 0.92 an average (n = 122), while in cases without laser coagulation the percentage improved only from 0.66 to 0.84 on average (n = 34) with a statistically significant difference (t = 2.64, P < 0.01). Laser coagulation was especially beneficial in the mixed form (n = 16), in which the visual acuity improved from 0.42 to 0.86 on average. The proportion of women increased from 10.7 to 17.9%. The patient age tended to be higher in women more than in men.
