Retrolental Fibroplasia and ERG

From the prognostic point of view, an electroretinogram is important in retrolental fibroplasia. Of the 98 personally examined cases in the last years, 65 (66%) had an extinguished ERG and belonged to the cicatricial stage grade IV or V. Thirty-two cases (34%) had some ERG response in one or both eyes (55 eyes). It may be predicted that a case with extinguished ERG has a poor prognosis and that vitrectomy with retinal attachment will not improve the function.
