Fusional Vergence Dysfunction a Case Report

Fusional vergence dysfunction is a binocular condition that is relatively easy to diagnose and treat but is often overlooked. FVD can negatively impact an individual’s ability to function, particularly when performing near work. A 17-year-old white female presented to our clinic with visual symptoms associated with sustained near work. The findings were characterized by normal phorias, poor but relatively balanced vergence ranges and low positive/ negative relative accommodation. A comprehensive eye/vision examination with a complete binocular vision evaluation revealed a fusional vergence dysfunction and a secondary accommodative dysfunction. The patient was successfully treated with a combination of a near vision spectacle correction and a course of optometric vision therapy.
