Fifty patients were administered subTenon’s anesthesia for the following surgeries: extra capsular cataract extraction with IOL implant (45), trabeculectomy(four), evisceration(one).
The administration of the anesthesia was painless. The anesthesia was excellent. At the beginning of surgery akinesia was incomplete in all the patients, especially the superior oblique muscle.
In 22 cases, slight action of the superior oblique was noted even after the surgery was over. The residual ocular movement did not interfere with surgery. There were no complications due to anesthesia.
