Strabismus after retinal detachment surgery is temporary in most cases. Long-term diplopia, however, is seen in 5% to 25% of patients. In most cases the cause is restrictive strabismus due to adhesions, muscle fibrosis, or scarring involving the buckling material. Deviations due to direct muscle injury and 'sensory' deviations due to poor vision also occur. Nonsurgical treatments include prisms and botulinum toxin injections. Surgical intervention using adjustable sutures is successful in most cases. (C) 2000 Lippincott Williams and Wilkins, Inc.
