[A long-term study of morphological and functional developments after central serous chorioretinitis].

Of 163 patients suffering from central serous chorioretinopathy, 40 who had been treated by light coagulation and 40 who had been treated conservatively were selected at random. They were examined at intervals averaging 5.7 and 4.6 years respectively after the initial treatment. Central visual acuity, central visual fields and the fundus were examined. The central visual acuity of the light-coagulated patients was normal both after initial treatment as well as at re-examination. In contrast, only one-half of the conservatively treated patients had normal visual acuity following initial treatment. However, after an average of 4.6 years it was normal in 34 cases. Neither quantitatively nor qualitatively was there any significant difference in the functional defects of the central visual fields in the two groups. The incidence of degenerative central retinal changes - above all at the level of the pigment epithelium - was considerably higher in the conservatively treated group than in the light-coagulated one.
