Abstract
Delayed visual maturation (DVM) is a term used to describe infants who do not exhibit the ability to fix or follow objects in the environment, but subsequently improves by the age of 6 months without treatment. Infants with these features were first described in the 1920s by Beauvieux, but today there remains little consensus as to the etiology of this phenomenon. This article reviews the existing literature on DVM and summarizes what is known about the classification, clinical characteristics and prognosis of this condition. In this article diagnosing DVM is discussed as well as a summary of other conditions to consider on the differential. Current thought on the etiology of this condition is explored. Ocular examination, electrophysiology tests, imaging results and central eye movements appear normal. These findings imply anterior and posterior sensory pathways as well as cortical motor pathways are intact in these patients. Given that these pathways are intact, a possible explanation for these symptoms includes temporary injury to the attention centers in the developing infant’s brain. Further research is needed to better understand the causes of this condition as well as the long-term sequela.
