Abstract:
PURPOSE: To identify a subtype of cone photoreceptor in the mammalian retina using enzyme histochemical method. METHODS: In human, rabbits and cats, identification of cone photoreceptor was tried with carbonic anhydrase after retinal tissue isolation and section. RESULTS: In human, subtype of cone photoreceptor was identified. In rabbits, one type of carbonic anhydrase negative regular cell was detected and suspected as rod cells. In cats, only blue cone cell and rod cell were detected and no red-green cone cell was detected. CONCLUSIONS: In cats and rabbits, identification of red-green cone cell and blue cone cell was difficult. So, enzyme histochemical identification of cone photoreceptor using carbonic anhydrase need more research to imply in mammalian retina.
