Abnormal Foveal Avascular Zone in Nanophthalmos

Nanophthalmic patients rarely have best-corrected visual acuity (BCVA) better than 20/40 at any point in their lives, even with an absence of known complications, such as uveal effusion or glaucoma. In many patients, this visual deficiency may correspond to an absent or rudimentary foveal avascular zone and lack of a normal foveal pit.
