ANATOMICAL RECOVERY FOLLOWING RETINAL DETACHMENT.

Abstract
The histological findings in experimental retinal detachment and reattachment of the cat retina are described. Loss of photoreceptor outer segments, mounding of the apical surface of the retinal pigment epithelium, and loss of the apical villi of the retinal pigment epithelium are prominent features of the detached cat retina. Reattachment within the 1st wk of retinal detachment is followed by good photoreceptor regeneration and orientation. Longer term detachment of 2-6 wk results in poorer photoreceptor outer segment regeneration and orientation 4 wk following reattachment surgery. These experimental results are consistent with [human] clinical data concerning visual recovery following retinal reattachment surgery.
