Progress in treatment of submacular hemorrhage due to polypoid choroidal vasculopathy / 国际眼科杂志(Guoji Yanke Zazhi)

ABSTRACT

@#Polypoidal choroidal vasculopathy(PCV)in the past referred to as “Idiopathic polypoidal choroidal vasculopathy(IPCV)”. It is a chronic vascular abnormality resulting in multiple, recurrent, serosanguinous retinal pigment epithelial detachments(PEDs)secondary to leakage and bleeding from choroidal vascular lesions. PCV have two types, including hemorrhagic type and exudative type, in which hemorrhagic type is prone to submacular hemorrhage. In recent years, with the widely used of indocyanine green angiography and optical coherence tomography angiography in ophthalmology, the research on this disease has gradually deepened. At present, the diagnosis of this disease is mainly confirmed by dilated pupil fundus examination, optical coherence tomography(OCT), OCTA, fluorescence fundus angiography(FFA)+ICGA and other auxiliary examinations. When complicated with a small amount of SMH, it can be absorbed by itself. When SMH is large, it is difficult to be absorbed by itself and has a great influence on vision. The main treatment included anti-VEGF drugs, PDT, gas, t-PA and combined vitrectomy. This article combining the latest progress in the study of domestic and foreign, the SMH induced by PCV epidemiology, pathogenesis, diagnosis, treatment were summarized, and the treatment methods were discussed and prospected.
