Evaluation of outer nuclear layer overshadowed by retinal vessels in retinitis pigmentosa

We investigated in vivo light-induced photoreceptor damage in retinitis pigmentosa (RP) using spectral-domain optical coherence tomography (SD-OCT) images. We retrospectively reviewed patients with genetic diagnosis of EYS-associated RP. The outer nuclear layer (ONL) thickness under retinal vessels was measured on SD-OCT vertical scans. As a control, we measured adjacent ONL thickness 100 μm superior and inferior from the vessel. Same...
