Abstract
The optic disc pit is a congenital anomaly, presenting as a round or oval depression in the optic disc, 0.1–0.7 disc diameters in size, located mainly along its lower-temporal margin. Approximately in 45-75% of the eyes with congenital optic disc pit a serous detachment of neuroepithelium (NED) in the macular area develops, which could become a cause for an erroneous diagnosis of an intraocular tumor. The article presents a clinical case of the optic disc pit, which required a differential diagnosis with an intraocular tumor. It is shown that OCT signs of the optic disc pit are: the connection of optic disc structures with the subretinal space, as well as the presence of signs of invagination of the retinal nerve fiber layer in the optic disc structures.
