[A case of microvascular anomalies in myopic retinoschisis].

It is a case found during routine reexamination one year after implantable Collamer lens (ICL) implantation. The patient had no complaints. The naked eye visual acuity of the left eye was 1.0, and abnormal blood vessels were seen in the supranasal retina. After fluorescein fundus angiography and sweep source OCTA, it was finally diagnosed as retinoschisis with microvascular anomalies of the left eye. This case suggests that the fundus of patients with high myopia without complaint should also be examined in detail and comprehensively. In addition to paying attention to peripheral retinopathy, the posterior pole and middle peripheral retina should be carefully examined, especially the areas that cannot be covered by conventional OCT.(Chin J Ophthalmol, 2021, 57: 944-945).
