Amblyopia and amblyopia treatment study

Abstract

Amblyopia comes from the Greek word meaning dull sight or blunt sight. Amblyopia occurs to abnormal visual experience early in life. It can be both unilateral (U/L) and/or bilateral (B/L). Amblyopia itself produces no change in the appearance of ocular structures, but it nearly always develops in association with some other condition that is evident on physical examination, and which is responsible for abnormal visual experience. It is one of the most common causes of visual impairment in childhood. Unless it is successfully treated in early childhood, amblyopia usually persists into adulthood. In 1997, the pediatric eye disease investigator group (PEDIG) was formed to conduct clinical research in eye disorders affecting children. The studies were conducted through simple protocols with limited data collection and implemented by both university and community based pediatric eye care practitioners as part of their routine practice in USA. Hence PEDIG has laid emphasis on studies of treatment modalities of amblyopia, the Amblyopia Treatment Studies (ATS). The recent general guidelines for occlusion therapy are based on ongoing ATS. New concepts of management on amblyopia are practiced now- a-days based on ATS. This article is an update on amblyopia and its management.
