Macromorphological evaluation of the Rs1tm1Bhfw/Y retina with scanning laser ophthalmoscopy

vision/eye
• at 3 months of age, cyst-like structures appear across the entire retina; large cysts in the retinal periphery occasionally displaced superficial vessels
• at 2 months of age, a severe disorganization of the inner nuclear layer is present
• at 2 months of age, a severe disorganization of the outer nuclear layer is present
• extracellular gaps were present between photoreceptor terminals; gaps filled with membraneous whorls and cellular debris
• three-fold fewer cones were present in mutant retinae
• variable absence of photoreceptor outer segments
• ERG analysis demonstrated a loss of b-waves; a-waves had amplitudes of half the normal state
• ERG responses were absent under light-adapted conditions suggesting dysfunction of the cone system

nervous system
• three-fold fewer cones were present in mutant retinae
• variable absence of photoreceptor outer segments
