Chorioretinal degenerative changes in the tilted disc syndrome.
Ninety patients (163 eyes) with tilted disc syndrome were examined in order to show possible chorioretinal degenerative lesions associated with the typical ectasia of the infero-nasal fundus observed in this anomaly. Eighteen out of the 163 eyes had pigmentary accumulations, either branched, linear or dotted and five had roundish areas of chorioretinal atrophy. Furthermore, in 7 eyes areas of pigmentary atrophy at the posterior pole were observed. The most serious lesions were represented by macular choroidal neovascular membranes, seen in 3 eyes, which were responsible for the loss of vision in these eyes. A relationship was found between the depth of the ectasia, the degree of tilt of the optic disc and the development of chorioretinal degeneration. Because of possible complication by macular choroidal neovascularization, the tilted disc syndrome can not be regarded in every case as a benign and not evolutive ocular anomaly.
