Multi-modal retinal imaging consistent with diagnosis of retinitis pigmentosa. A. Wide field retinal photograph depicting mid peripheral bone spicule pigmentation and perivascular atrophy. Superonasal artifact from finger holding up eyelid, eyelashes from lower lid. B. Red-free wide-field photograph demonstrating widespread areas of chorio-retinal atrophy in the left eye, seen as hypofluorescent /dark patches (indicated by arrow). C. OCT image of Right Macula depicting lamellar macular hole (indicated by large arrow). There is disruption of the inner retinal layers, however the thinned retinal pigment epithelium is intact (smaller arrow). D: Control wide field retinal photographa (Optos, 2022. Healthy.
