The eyes of three patients with trisomy 18, the second most common human autosomal trisomy, were examined histopathologically. In the posterior retina transmission and scanning electron microscopic examinations reveal cytological details characteristic of immature neural retinas. We are able to confirm the report that the posterior retinal pigment epithelium in trisomy 18 has a paucity of mature melanosomes and, in fact, resembles human albino retinal pigment epithelium. The association of hypopigmentation and retinal immaturity suggests pigmentation plays a role in the control of the maturation of the neural retina.
