Isolated Foveal Hypoplasia Assessed by Multi-Focal Electroretinogram: A Clinical Presentation

Abstract

Foveal hypoplasia is a term commonly used to describe the lack of development or underdevelopment of the foveal pit which anatomically and functionally correlates with a region of high visual acuity. Despite the fact that, fovea facilitates more precise and greater visual processing, the absence of foveal pit does not mean, a priori, poor visual acuity. While foveal hypoplasia has been usually associated with variable ocular abnormalities, isolated foveal hypoplasia though rare, has been also described. We present a case of a 31 year-old Caucasian male with an isolated foveal hypoplasia and the clinical evaluation in combination with the imaging findings, documented by multifocal ERG for the first time in literature.
