Abstract

Functional visual loss (FVL) is a decrease in visual acuity or visual field not caused by any organic lesion. It is therefore also called as “nonorganic visual loss “(NOVL). This entity is considered within the spectrum of “conversion disorder”, malingering, somatic symptom disorder, and “factitious disorder” [1]. The decrease in visual acuity may involve one or both eyes and may vary from mild blurriness to complete blindness.
