vision/eye
short photoreceptor inner segment ( J:181417 )
• by 2 months of age, the inner segments of the retina are shortened
short photoreceptor outer segment ( J:181417 )
• by 2 months of age, the outer segments of the retina are shortened
disorganized photoreceptor outer segment ( J:181417 )
• outer segments are disorganized with disruption of the conventional parallel arrangement of disc membranes and poorly defined outer segment morphologies; perimeters are undefined and disc diameters are greatly expanded
• stacks of disc membranes are occasionally arranged parallel to the long axis of the outer segments instead of the normal perpendicular orientation
abnormal retina cone cell morphology ( J:181417 )
• cone opsins show mislocalization in the inner segment, perinuclear regions and synaptic terminals
retina photoreceptor degeneration ( J:181417 )
• photoreceptor cell loss is seen by 2 months of age
• retinal cell degeneration is rapid with complete loss of photoreceptors by 8 months of age
abnormal retina outer nuclear layer morphology ( J:181417 )
• by 2 months of age, mutants show a decrease in the number of nuclei in the outer nuclear layer
