After sealing peripheral retinal tears in retinal detachment surgery by means of cryoapplications, neovascularization appeared, stemming from the choroidal circulation. This complication was noted in three cases of retinal detachment with tears in an area of latticelike degeneration. The neovascularization, clearly originating from the choroid, extended into the vitreous cavity through the chorioretinal scar created by the cryoapplication. Repeated attempts to destroy the neovascularization with argon laser applications proved unsuccessful. In the 4--6-year follow-up of the cases recurrent hemorrhages were observed. The etiology of the neovascularization remains unknown, but it is probably related to the presence of subretinal pigment epithelium neovascularization encountered in a high percentage of adults in the retinal periphery. The choroidal neovascularization described provides evidence that, in addition to xenon arc and argon laser applications, cryoapplication on the retina can also cause this rare complication.
在通过冷冻疗法封闭视网膜脱离手术中周边视网膜裂孔后，出现了源于脉络膜循环的新生血管形成。在三例伴有格子样变性区域裂孔的视网膜脱离病例中发现了这种并发症。新生血管明显起源于脉络膜，通过冷冻疗法造成的脉络膜视网膜瘢痕延伸至玻璃体腔。多次尝试用氩激光破坏新生血管均未成功。在对这些病例进行4至6年的随访中观察到了复发性出血。新生血管形成的病因尚不清楚，但可能与视网膜周边高比例成年人中出现的视网膜下色素上皮新生血管形成有关。所描述的脉络膜新生血管形成提供了证据，表明除了氙弧光和氩激光应用外，视网膜冷冻疗法也可导致这种罕见的并发症。
