Familial chronic central serous chorioretinopathy

Twenty-seven patients with characteristic, mostly bilateral, fundus lesions of chronic central serous chorioretinopathy (CSC) and a progressive course, and 80 of their relatives, mainly siblings, were examined. Ophthalmologic examination included assessment of visual acuity, Amsler grid testing, ophthalmoscopy and fluorescein angiography. The fundus findings were classified as normal fundus, multiple areas of retinal pigment epithelium (RPE) atrophy or chronic CSC: RPE atrophy with leakage of fluorescein. In 14 (52%) of the 27 families, 1 or more relatives were affected. Thirty-five (44%) of the 80 investigated relatives had fundus lesions: 22 had chronic CSC in one eye, 20 of these had chronic CSC or RPE atrophy in the fellow eye. Thirteen relatives had RPE atrophy in one or both eyes. The mode of inheritance could not be established.
