cross fixation

A condition where a patient with a large, alternating esotropia uses the adducted eye to fixate on objects in the opposite temporal field. It frequently occurs in cases of infantile esotropia. The patient alternates fixation between the two eyes, with one eye fixating on objects in the nasal field while the other eye crosses over to fixate on objects in the temporal field. This adaptation allows the patient to maintain some degree of binocularity despite the misalignment of the eyes.
