A patient with a macular pit, defined as a focal scleral excavation, was examined. The axial length of the pit was 30.0 mm. Ophthalmoscopic examination showed a yellowish oval lesion within a wide area of chorioretinal atrophy. A ringlike low reflectance pattern was detected on infrared examination (Figure, A). Spectral-domain optical coherence tomography revealed a focal scleral ectasia with no overlying retina (Figure, B). The sclera was approximately one-third thinner (98, 77, and 50 μm for the pit’s floor, temporal wall, and nasal wall, respectively), and the choroid was obliterated. The pit had a homogeneous low autofluorescence. Fluorescein angiography showed a branch of a posterior ciliary artery in the vicinity of the lesion. The pit was slightly hyperfluorescent in the late frames.
