Abstract

The migration of photoreceptors into the subretinal space has been reported to occur in developing and aged rat retina, in aged human retina, in detached owl monkey, and in detached cat retina. Subretinal photoreceptor cells have been observed in aphakic-vitrectomized rabbit eyes with or without intravitreal saline or antibiotic injection. Variety of photoreceptor cell nuclei can be distinguished. The nuclei of photoreceptor cells change their shape so as to pass easily through the juncition and thereafter they returned to their original shape in sub retinal space. The mechanisms and biological significance of this phenomenon are not yet certain, but it may by one of the important factors contributing to decreased vision with aging.
