To document optical coherence tomography (OCT) findings in a series of eyes with group 2A idiopathic juxtafoveal telangiectasia.
This study is a retrospective review of patient charts, OCT, fundus photography, and fluorescein angiography involving 23 eyes (12 patients). Mean retinal thickness in 9 macular areas was calculated and compared to previously published measurements from normal eyes.
OCT in 8 of 13 stage 3 eyes revealed foveal cysts without evidence of cystoid macular edema on fluorescein angiography or biomicroscopy, and 1 lamellar hole. In stage 3 eyes, mild retinal thickening was found in 7 of 9 macular areas (P < .05).
OCT commonly reveals foveal cysts in stage 3 idiopathic juxtafoveal telangiectasia. Consistent findings of associated mild macular thickening and lack of late petaloid hyperfluorescence on fluorescein angiography suggest that these cysts differ in pathophysiology from cystoid macular
记录一系列2A组特发性黄斑旁毛细血管扩张症患者眼睛的光学相干断层扫描（OCT）结果。
本研究是一项对23只眼（12例患者）的病历、OCT、眼底照相及荧光素血管造影的回顾性研究。计算9个黄斑区域的平均视网膜厚度，并与之前发表的正常眼睛测量值进行比较。
13只3期眼中的8只，OCT显示有黄斑囊肿，荧光素血管造影或生物显微镜检查未发现黄斑囊样水肿证据，还有1只存在板层裂孔。在3期眼中，9个黄斑区域中的7个发现轻度视网膜增厚（P < .05）。
OCT通常显示3期特发性黄斑旁毛细血管扩张症存在黄斑囊肿。荧光素血管造影显示相关的轻度黄斑增厚以及缺乏晚期花瓣状高荧光的一致发现表明，这些囊肿在病理生理学上与黄斑囊样水肿不同。
