渗出型老年性黄斑变性的光学相干断层扫描观察

目的 观察渗出型老年性黄斑变性(age-related macular degeneration,AMD)的光学相干断层扫描(optical coherence tomography,OCT)图像特征。 方法 对荧光素眼底血管造影(fundus fluorescein angiography,FFA)确诊的16例渗出型AMD患者的19只患眼作OCT检查，其中4例6只眼并进行吲哚青绿血管造影(indocyanine green angiography, ICGA)检查。对其彩色眼底像、FFA、ICGA和OCT图像资料进行比较。 结果 与FFA、ICGA检查结果比较，AMD患眼的OCT改变主要有：①浆液性神经上皮脱离和层间水肿11只眼；②视网膜层间出血2只眼；③浆液性色素上皮脱离5只眼；④出血性色素上皮脱离10只眼；⑤瘢痕性脉络膜新生血管(choroidal neovascularization,CNV)4只眼；⑥纤维血管膜性色素上皮脱离和隐匿型 CNV 12只眼。 结论 OCT从断面上观察和诊断渗出型AMD病变，对FFA、ICGA有补充作用。(中华眼底病杂志,2000,16:220-223)

Characteristics of exudative age-related macular degeneration optical coherence tomography

Objective To verifying the characteristics of optical coherence tomography(OCT) in exudative age-related macular degeneration (AMD). Methods The patients being investigated in this series included 16 cases (19 eyes) of exudative age-related macular degeneration diagnosed by FFA and OCT examinations, among them 4 cases (6 eyes) were examined with ICGA. The color photographs of ocular fundi, FFA, ICGA and OCT were investigated by contrasting each other. Results As compared with the FFA and ICGA examinations, the characteristic findings found in OCT in patients with exudative AMD in this series were as the following:①serous detachment of neurosensory epithelium in 11 eyes,②retinal hemorrhage in 2 eyes,③serous detachment of retinal pigment epithelium in 5 eyes,④hemorrhagic detachment of retinal pigment epithelium in 10　eyes,⑤disciform scar in 4　eyes,⑥fibrovascular pigment epithelial detachment and occult CNV in 12 eyes. Conclusion OCT can supply a comprehensive survey of exudative AMD, in making the diagnosis as an important complementary examination of FFA and ICGA.(Chin J Ocul Fundus Dis,2000,16:220-223)
