Focal choroidal excavation (FCE) is a localized excavation of the choroid, which can be diagnosed by enhanced depth optical coherence tomography (OCT). Choroidal caverns are focal cavitation areas in the choroid which appear hyporeflective on OCT. These are angular or round, empty spaces with posterior tail of hypertransmission. A 47-year-old female presented to us for a routine eye check-up. The best-corrected visual acuity was 20/20 in both the eyes. On fundus examination, a localized pigmented lesion was seen in the right eye inferior to the optic disc, while the fundus of the left eye was normal. Spectral-domain OCT scan through the lesion showed an FCE and a giant cavern with a posterior tail of hypertransmission. The diameter of the cavern was 977 μ ×264 μ, with a subfoveal choroidal thickness (SFCT) of 360 μ. The SFCT of the other eye was 300 μ. Coexistence of FCE and cavern in an eye with thickened choroid is not yet reported in the literature, and their coexistence provides possible insight into the formation of FCE and caverns in the setting of thickened choroid.
