Abstract:  The posterior ciliary artery occlusion (PCAO) can manifest multiple patterns, with totally different clinical characteristics associated with stages, ranging from unrecognizable retinal abnormality to severe pigmented fundus. Great variability can be noted in the distributions, morphology, sizes and extents of ischemia lesions. What’s more, different degrees of ischemia can be appeared in a same fundus of PCAO because of complex compensatory mechanisms. The clinical features of optic nerve head ischemia caused by PCAO also varies depending on different etiologies, such as non-arteritic, arteritic, diabetic. (Ophthalmol CHN, 2024, 33: 169-177)
