Esotropia
Conditions
Brief summary
Adult patients requiring surgery for esotropia will be randomized to surgery under topical anesthesia or sub-Tenon's anesthesia. Amount of surgery required with the two anesthetic procedures will be compared. Motor and sensory outcome of the two treatment groups will also be compared.
Interventions
Surgery is carried out after instilling drops for anesthesia and administering lidocaine gel during the procedure
Surgery is carried out after sub-Tenon's injection of xylocaine
