vision/eye

abnormal retina morphology ( J:265859 )

• at 18 days of age there are areas of retinal depigmentation lacking fluorescein leakage, the number and size of spots increases and some fluorescein leakage is found at 25 days of age, by 3 weeks of age subretinal vascularization and disturbance of the outer retina are found, and eventually the depigmented spots become large areas of depigmentation with aberrant blood vessels spaning from the retinal pigment epithelium to the inner nuclear layer accompanied by photoreceptor cell degeneration
