Functional vision disorders in adults: a paradigm and nomenclature shift for ophthalmology
2022, Survey of OphthalmologyCitation Excerpt :With binocular testing, the “good” eye can compensate for the defect in the “bad” eye; however, patients with FVD may exhibit a persistent defect in the pattern of the monocular field defect on binocular testing (Fig. 4) [40]. Loss of the blind spot in binocular VFs in a patient with monocular blindness suggest FND [47]. Automated perimetry: Though some Goldmann manual perimetry findings suggestive of FND can be elicited on automated kinetic perimetry, the result of a constricted VF on automated monocular static perimetry cannot distinguish between a patient with ophthalmic disease and a patient with FVD [40].
Functional (Nonorganic) Visual Loss

2014, OphthalmologyCitation Excerpt :This phenomenon was first described by Glovinsky et al,3 who demonstrated that it was easy for an ophthalmologist to create a quadrantic field defect by ignoring the initial stimulus presented by the perimeter in that quadrant. Stewart5 subsequently demonstrated that healthy volunteers were able to produce quadrantic defects that were “more neurologic” than patients with pituitary adenomas and there were no visual field criteria to differentiate from a true defect. In a similar but much smaller study compared with ours, Thompson et al6 asked 6 volunteers to simulate 6 different visual fields and repeat them on a Goldmann perimeter.
