PURPOSE
To define the structure of optic disk pit maculopathy.
METHODS
A patient was examined with optic coherence tomography before and after an intravitreal gas tamponade.
RESULTS
Before intravitreal gas injection, optic coherence tomography defined a separation between the inner and outer layers of the retina that connected with the optic disk pit. An outer retinal layer detachment that centered on the fovea was also present. After pneumatic displacement of the intraretinal and subretinal fluid, optic coherence tomography disclosed that the two layers were opposed and in contact with the retinal pigment epithelium.
CONCLUSIONS
Optic coherence tomography confirmed the two-layer structure of optic disk pit maculopathy and demonstrated the positive effect of pneumatic displacement.
目的
明确视盘小凹黄斑病变的结构。
方法
对一名患者在玻璃体内气体填塞前后进行光学相干断层扫描检查。
结果
在玻璃体内注入气体前，光学相干断层扫描显示视网膜内层和外层之间存在与视盘小凹相连的分离。还存在以黄斑为中心的外层视网膜脱离。在视网膜内和视网膜下液进行气体置换后，光学相干断层扫描显示两层相对并与视网膜色素上皮接触。
结论
光学相干断层扫描证实了视盘小凹黄斑病变的两层结构，并显示了气体置换的积极效果。
