Abstract:  As focal ischemic lesions of retinal pigment epithelium (RPE) resulted from choroidal lobule infarction, Elsching spots are characters of accelerated hypertensive choroidopathy. A localized injury or even necrosis of the RPE will be resulted from focal ischemia, presenting as multiple, isolated round orange-yellow or yellow-white subretinal spots, i.e. Elschnig spots. Subsequently, depigmentation and atrophy of the RPE gradually occur. In the acute phase, RPE ischemia can be manifested as thickening and elevation of the RPE by optical coherence tomography, and a V-shaped adhesion is formed between the RPE and the overlying partly detached neurosensory retina. This is an important characteristic for differentiating it from other diseases such as Vogt-Koyanagi-Harada (VKH) disease. (Ophthalmol CHN, 2025, 34: 185-193)
