What is the best treatment for this condition? When is the optimum time to intervene?
The deviation is best treated with surgery. The standard procedure is to do this between 6 months and 2 years of age to in order to achieve peripheral fusion (1). However, some authors found that doing surgical intervention earlier than 6 months of age may result to good alignment and high-grade stereopsis (2). Early surgery is indicated when the amount of deviation is very large (40 prism diopters or larger), and when the deviation is found to be becoming constant or increasing in amount documented in two consecutive visits several weeks apart. Of course, the child has to be healthy enough to undergo the surgery under general anesthesia. Spontaneous resolution is a possibility in small deviations; however, it is highly unlikely to happen in large deviations.
