pigmentation
|
• retinal pigment epithelium exhibits increased irregular-shaped dark granules indicative of lipofuscin deposits
|

pigmentation
|
• increase in lipofuscin autofluorescence in the fundus
|
vision/eye
|
• cone responses appear somewhat faster than those of control single Gnat1 homozygotes
• the maximum cone response amplitude is about 20% lower than in single Gnat1 homozygous controls
• the later phase of cone dark adaptation in vivo is delayed, however the early phase of cone recovery is not affected
