Retrolental fibroplasia in full-term infants without exposure to supplemental oxygen.

We observed retinal folds identical in appearance to Grade 3 cicatricial retrolental fibroplasia in three infants at birth. In two of them we observed the active lesion of acute retrolental fibroplasia in the fellow eye at birth. These observations lead us to suggest that the active lesion of retrolental fibroplasia can occur in utero and progress to cicatrization in the absence of any obvious precipitating factor.
