This case report comprises studies of four Goeldi's monkeys (Callimico goeldii) from the same enclosure. Globe samples from two related C goeldii (the female C goeldii and her male offspring) were available for a histopathological evaluation. Both cases presented histopathologically evident outer retinal degeneration with differences in severity. There was marked outer retinal atrophy characterized by loss of the outer and inner photoreceptor segments, and depletion of the outer retinal nuclear layer. Furthermore, we report a reduction in the thickness of the outer retinal plexiform, inner retinal nuclear layer, and inner retinal plexiform layer in these C goeldii monkeys. To the authors’ knowledge, these findings have not yet been reported in wild‐ or captive‐bred population of C goeldii.
