Abstract
PURPOSE: The purpose of this study was to report a case with a cup-shaped choroidal excavation in the fovea. This condition was detected only by optical coherence tomography (OCT) and seems to be rare. METHOD: This was an observational case report. RESULT: A 29-year-old man had a central scotoma in his right eye. Color photography showed a reddish lesion in the fovea of the right eye, which was shown as a window defect on fluorescein angiography. Tomography with time-domain OCT showed a retinal pigment epithelial and choroidal excavation corresponding to the reddish macular lesion in the right eye. By using spectral-domain OCT, the inner segment and outer segment junctions of photoreceptors line thickening was detected by tomography, and the retinal pigment epithelium line was observed in the area of choroidal excavation by segmentation analysis. CONCLUSION: The reddish lesion on ophthalmoscope corresponded to the excavation lesion, detected in the fovea only by OCT; this indicates a new clinical availability of OCT in clinical diagnosis.
