Screening and Diagnosis for Vision Loss


All children, youth, and adults are unique, and vision loss can be as unique as each child, so detection of vision loss can be challenging. Diagnosing a problem for a young child may be something that is immediate due to congenital conditions, the appearance of the eyes, or it may become more obvious due to signs that appear as the child matures. If you have concerns about vision in an individual with whom you live or work, following up with that concern and getting it checked is a good plan of action.

Vision screenings can be performed using a number of methods depending on the age of a child to determine if there is a suspected visual impairment or eye condition. The initial screening usually begins at birth with an examination of the newborn’s eye, pupil, and reflex.

Early detection, diagnosis, and treatment of any degree of vision loss helps improve communication and connection with the world. The types of tools used to begin to identify issues related to vision through screening become the baseline for what a optometrist or ophthalmologist may address in a follow-up clinical exam.
