Microanatomical studies on age related changes in the macula retina of buffaloes (Bubalus bubalis)

Abstract

The retina macula appeared as strip-like and pale in colour located dorsal to the optic disc in buffaloes. Retina macula contained large RPE cells with tightly packed melanin pigment, a relatively larger number of cone cells, cells of inner nuclear, inner plexiform and nerve fibre layers showed less cystoid degeneration when compared to the peripheral retina. The total thickness (µm) of retinal macula in groups I, II and III was 229.05±3.56, 230.55±3.28 and 231.72±2.87 respectively. There were few degenerating changes observed in the macula when compared to the peripheral retina with the advancement of age in buffaloes.
