Purpose: To describe the retinal findings in two cases of Alport syndrome.

Methods: Observational case series. The clinical findings of the two patients were documented with color fundus photography and high resolution spectral domain optical coherence tomography.

Results: Patient 1 was found to have fleck retinopathy in both eyes, inner retinal thinning in the right eye and a full-thickness macular hole in the left eye. Patient 2 was found to have a full-thickness macular hole in the right eye as well as retinoschisis in the temporal macula in the right eye. The left eye revealed inner retinal thinning involving the fovea, a vitelliform lesion of the temporal macula and midperipheral retinoschisis involving multiple retinal layers.

Conclusion: Retinal abnormalities including fleck retinopathy, retinal thinning, macular holes, retinoschisis, and vitelliform lesions are variably present in Alport syndrome. This is only the second report of a vitelliform lesion in a patient with Alport syndrome and the first report of midperipheral retinoschisis. The array of retinal findings is believed to reflect a dysfunctional Type IV collagen present in the internal limiting membrane and Bruch membrane.

Alport syndrome is a rare hereditary condition with variable retinal findings. The authors report two cases of Alport syndrome with both previously reported and novel retinal findings.
