Amblyopia and the monofixation syndrome.
Children with a Monofixation syndrome often show a small angle constant esotropia with an overlying esophoria of variable and often large angle. Commonly the phoria is well controlled unless the child is very tired, or the eyes are dissociated. Treatment of a concomitant amblyopia by patching may result in an inability to control the phoria, with breakdown of the strabismic angle to a large esotropia. Illustrative cases are presented.
