Myopic submacular hemorrhage (SMH) usually arises from either a break in Bruch's membrane (lacquer cracks) that damages the underlying choriocapillaris or the development of a choroidal neovascular membrane (CNVM) at the sites of prior lacquer cracks.1,2 In pathologic myopia (PM), axial elongation leads to thinning of the choroid and retinal pigment epithelium, predisposing to rupture of Bruch's membrane.3 If large hemorrhages involving the fovea are left untreated, subretinal hemorrhage and CNVM can cause devastating long-term vision loss due to irreversible retinal atrophy.4 In this video, the authors describe their technique of using a subretinal injection of recombinant tissue plasminogen activator with a concurrent gas tamponade to displace SMH.
近视性黄斑下出血(SMH)通常源于Bruch膜破裂(漆裂纹),其会损伤下方的脉络膜毛细血管,或者源于先前漆裂纹部位脉络膜新生血管膜(CNVM)的形成。1,2 在病理性近视(PM)中,眼轴延长会导致脉络膜和视网膜色素上皮变薄,易引发Bruch膜破裂。3 如果累及黄斑中心凹的大量出血未得到治疗,视网膜下出血和CNVM可因不可逆的视网膜萎缩导致严重的长期视力丧失。4 在本视频中,作者描述了他们使用视网膜下注射重组组织型纤溶酶原激活剂并同时进行气体填塞来置换SMH的技术。
