    Outer retinal tubulation (ORT) is a feature of photoreceptor rearrangement after chronic retinal damage due to refractory cme, long standing CNVM or old trauma. Photoreceptors lose adhesions to surrounding structures, resulting in outward folding and formation of new lateral contact between photoreceptors to form round structure. They generally remains stable over time. It is important to recognize ORT on OCT because it indicates a refractory state of the pathological condition and poor visual prognosis, and likely not to benefit from any treatment. Here is a case of 62-year-old female with history of 4 previous anti-VEGF injection in left eye for CNVM, with the recent OCT showing formation of ORT with subfoveal scarred membrane.
