Funduscopic appearance of the lesion. Note the yellow-white and discrete lesion with a surrounding orange halo a configuration that is consistent with solitary idiopathic choroiditis (A). Normal funduscopic left eye (B). (C) Fundus autofluorescence imaging demonstrates hyperautofluorescence (arrows). (D) B-scan ultrasonography showing a high echogenicity (arrow).

On dilated exam, the left fundus was normal (Figure 1A). Examination of the right fundus revealed a round deep yellow-white mass without visible subretinal fluid, 1.25 mm in diameter, located in the peripapillary area, inferonasal to the optic disc (Figure 1B). Fundus autofluorescence showed mild intrinsic hyperautofluorescence (Figure 1C). There was no evidence of calcification within the mass (Figure 1D).
(A) SS-OCT imaging confirms the diagnosis as the lesion can clearly be seen coming up from the sclera and compressing the overlying choroid and choriocapillaris. The lesion is inactive as there is no sign of yellow intraretinal exudation, localized subretinal fluid or focal retinal hemorrhages and the posterior border (arrows) of the lesion is well defined. (B) Cross-sectional composite OCT angiogram. The lesion is avascular. Overlying choroidal vasculature is thinned. Flow signals are color coded: purple, choroid; red, neuroretina.

Topcon Medical Systems, Inc.) disclosed an intrascleral shape mass with round configuration and visible posterior margin that was associated with compression of overlying choroidal layer. The choroid was almost absent at the apex of the mass (Figure 2).
OCT angiography: resulted in fewer choriocapillaris flow voids (between arrows).

OCT angiography (OCTA), choriocapillaris flow impairment was seen overlying the SIC lesion. OCTA images show an avascular lesion (Figure 3).
