homeostasis/metabolism
• retinas have a selective deficit of 22:6,n-3-containing phospholipids and very long-chain polyunsaturated fatty acids

nervous system
• progressive degeneration of rods and cones as detected by electroretinogram; age of onset is approximately 1 month

vision/eye
• Relative to C57BL/6J controls, homozygotes develop a smaller posterior eye and shorter posterior chamber depth leading to a shorter axial length, although the anterior chamber depth is longer, and decreased corneal radius of curvature
• progressive degeneration of rods and cones as detected by electroretinogram; age of onset is approximately 1 month
• loss of outer nuclear layer progresses more quickly with age than does that of C57BL/6J controls
• age of onset is approximately 7 months (J:64087)
• decreased retinal thickness and outer nuclear later thickness with age relative to C57BL/6J controls, and increased Muller glia by 4 months of age (J:364267)
• subretinal spots oriented in a regular pattern across the retina are apparent by ophthalmoscopic examination at approximately 8-10 weeks of age
