OBJECTIVE
To observe the characteristics of optical coherence tomography (OCT) for exudative age-related macular degeneration (AMD).
METHODS
Thirty-eight patients (42 eyes) diagnosed as exudative AMD by color fundus photography, fundus fluorescein angiography (FFA) and indocyanine green angiography (ICGA) were examined by OCT. The results of OCT were analyzed and compared with that of FFA and ICGA.
RESULTS
The characteristics of OCT for exudative AMD: fibrotic choroidal neovascularization (34 eyes), serous detachment of neurosensory epithelium (38 eyes), detachment of the nerve fiber layer (8 eyes), and hemorrhagic and serous detachment of retinal pigment epithelium (11 eyes and 9 eyes, respectively).
CONCLUSION
The major characteristic of OCT of exudative AMD is fibrotic choroidal neovascularization combined with serous and hemorrhagic detachment of neurosensory epithelium or retinal pigment epithelium, which would be helpful for diagnosing and evaluating exudative AMD.
目的
观察光学相干断层扫描（OCT）对渗出性年龄相关性黄斑变性（AMD）的特征表现。
方法
对38例（42只眼）经彩色眼底照相、眼底荧光血管造影（FFA）及吲哚菁绿血管造影（ICGA）诊断为渗出性AMD的患者进行OCT检查。分析OCT结果并与FFA和ICGA结果进行比较。
结果
渗出性AMD的OCT特征表现为：纤维性脉络膜新生血管（34只眼）、神经感觉上皮浆液性脱离（38只眼）、神经纤维层脱离（8只眼）以及视网膜色素上皮出血性和浆液性脱离（分别为11只眼和9只眼）。
结论
渗出性AMD的OCT主要特征是纤维性脉络膜新生血管合并神经感觉上皮或视网膜色素上皮的浆液性和出血性脱离，这有助于诊断和评估渗出性AMD。
