Binocular visual field changes after surgery in esotropic amblyopia.

Purpose: To determine binocular visual field (BVF) changes after strabismus surgery in children with large angle esotropia, and whether these changes can be predicted, using a prism to correct the preoperative angle of deviation.

Methods: Monocular visual field (MVF) and BVF were measured by Goldmann perimetry in healthy adults (n = 6) using a range of prisms. Visual fields were then measured in normal children (n = 19) and in children with large angle esotropic amblyopia (n = 28).
