This case report describes a 19-year-old Caucasian man presented with decreased visual acuity in the right eye for 3 months. Dilated funds exam revealed optic disk pit associated with serous macular detachment. Optical coherence tomography identified communication between the optic disk pit and the macular serous detachment, and optical coherence tomography angiography displayed a subfoveal area suggestive of subfoveal choroidal neovascularization. However, there was no evidence of leakage in the fluorescein angiogram and no evidence of choroidal neovascularization in optical coherence tomography in the area corresponding to the suspicious subfoveal choroidal neovascularization. The patient underwent 23-gauge pars plana vitrectomy in the right eye. Six weeks after surgery, multimodal imaging was repeated and there was near-complete resorption of the subretinal fluid. Optical coherence tomography angiography signal superimposed on optical coherence tomography B-scan also demonstrated normal choriocapillaris signal throughout the macula. In conclusion, optical coherence tomography angiography may produce artifacts in optic disk pit maculopathy that simulate choroidal neovascularization.
本病例报告描述了一名19岁的白种男性，右眼视力下降3个月。散瞳眼底检查发现视盘凹陷伴浆液性黄斑脱离。光学相干断层扫描确定视盘凹陷与黄斑浆液性脱离之间存在连通，光学相干断层扫描血管造影显示黄斑下区域提示黄斑下脉络膜新生血管形成。然而，荧光素血管造影未显示渗漏迹象，在对应于可疑黄斑下脉络膜新生血管形成的区域，光学相干断层扫描未发现脉络膜新生血管形成的证据。该患者右眼接受了23G经平坦部玻璃体切除术。术后六周，重复进行多模态成像，视网膜下液几乎完全吸收。光学相干断层扫描血管造影信号叠加在光学相干断层扫描B超上，也显示整个黄斑区脉络膜毛细血管信号正常。总之，光学相干断层扫描血管造影在视盘凹陷性黄斑病变中可能产生模拟脉络膜新生血管形成的伪像。
