Abstract
Vascular casts were made of the choriocapillaris (CC) of rabbits that received sodium iodate intravenously 6-28 days prior to examination, in order to augment studies of CC regeneration in sectioned material. Regeneration of CC was evident 6 days after administration of iodate where zones of spared CC bordered zones of atrophic CC. Venular as well as capillary sprouts created foci of regenerating CC at this border. These foci to create an extended capillary plexus similar to mature CC. The observations corroborate those obtained in sectioned material as regards the geography of the CC response and the origins of new CC during the sodium iodate retinopathy, and provide new information on the way in which CC regenerates.
