WebJan 25, 2024 · Outer retinal tubulation (ORT) is a feature of photoreceptor rearrangement after retinal injury.[1][2] Degenerating photoreceptors are arranged in a circular or tubular fashion. ORT is most commonly seen in neovascular age-related macular degeneration (AMD) but is also seen in various chronic degenerative retinal disorders.[1] This … WebOCT can be used to differentiate between true MH and conditions that may appear similar on clinical examination, including lamellar macular hole and pseudohole, among others. …
