To present a new phenotype of torpedo maculopathy on spectral domain optical coherence tomography imaging (SD-OCT).
A 31-year-old female presented with a multi-partite yellowish lesion in the macula of her left eye, with a central fovea-involving component and a temporal tail-like component. The lesion showed mixed hyper- and hypoautofluorescence on fundus autofluorescence imaging. The fovea-involving component exhibited disruption of ellipsoid zone without outer-retinal cavitation on SD-OCT, consistent with the prior-described type 1 OCT morphology. The temporal tail showed subtle inner choroidal excavation with preservation of the ellipsoid zone and outer-retinal structures.
Inner choroidal excavation with preservation of the overlying outer-retinal structures represents a novel morphological phenotype on SD-OCT in torpedo maculopathy. This case demonstrates that distinct morphological subtypes may co-exist in different regions of the same torpedo maculopathy lesion.
在频域光学相干断层扫描成像（SD-OCT）上呈现鱼雷状黄斑病变的一种新表型。
一名31岁女性左眼黄斑区出现多部分淡黄色病变，有累及中央凹的成分和颞侧尾状成分。该病变在眼底自发荧光成像上显示混合性高自发荧光和低自发荧光。累及中央凹的成分在SD-OCT上表现为椭圆体带破坏但无视网膜外层空洞，与先前描述的1型OCT形态一致。颞侧尾部显示脉络膜内层细微的挖空，椭圆体带和视网膜外层结构保存。
脉络膜内层挖空且上方视网膜外层结构保存是鱼雷状黄斑病变在SD-OCT上的一种新形态表型。该病例表明，在同一鱼雷状黄斑病变的不同区域可能共存不同的形态学亚型。
