The aim was to describe a pathogenic mechanism for a rhegmatogenous retinal detachment in a 69-year-old man with the morning glory syndrome.
During vitreous surgery for a retinal detachment, a membrane was removed that covered the optic disc anomaly and produced traction on the peripapillary retina. A retinal hole was found in tissue lying within the optic cup, and the hole was sealed using a autologous plasma-thrombin mixture. Silicone oil was used for retinal tamponade.
A retinal hole in tissue lying within the optic cup provided a fluid pathway between the vitreous cavity and the subretinal space. Following vitrectomy surgery, bubbles of silicone oil passed through the retinal hole into the subretinal space of the macula.
This case demonstrates that a retinal hole in tissue lying within the optic disc anomaly of the morning glory syndrome provides a communication for fluid between the subretinal space and the vitreous cavity, resulting in a rhegmatogenous retinal detachment. Vitreous replacement with silicone oil resulted in the migration of silicone bubbles into the subretinal space.
目的是描述一名患有牵牛花综合征的69岁男性孔源性视网膜脱离的致病机制。
在视网膜脱离的玻璃体手术中，切除了覆盖视盘异常并对视乳头周围视网膜产生牵引的膜。在视杯内的组织中发现一个视网膜裂孔，并用自体血浆 - 凝血酶混合物封闭该裂孔。使用硅油进行视网膜填塞。
视杯内组织中的视网膜裂孔提供了玻璃体腔与视网膜下间隙之间的液体通路。玻璃体切除术后，硅油气泡通过视网膜裂孔进入黄斑的视网膜下间隙。
该病例表明，牵牛花综合征视盘异常内组织中的视网膜裂孔为视网膜下间隙与玻璃体腔之间的液体提供了连通，导致孔源性视网膜脱离。用硅油置换玻璃体导致硅油气泡迁移到视网膜下间隙。
