[Echographic studies in cases of excentric posterior scleral ectasias (author's transl)]

Excentric posterior scleral ectasias are rarely recognized correctly. They can cause uncharacteristic visual disturbances and refractive scotomas, which may cause a mis-diagnosis of bitemporal hemianopia. In this report 10 such cases are shown. The diagnosis was verified by the ultrasonographic measurement of the meridional length of the eye. Posterior scleral ectasias of maximum 4.5 mm were found.
