All patients were injected with up to 1 ml of a 1:1mixture of 2% lignocain with</p><p>epinephrine and 0.75% bupivacaine sub-conjunctivally and operated for trabeculectomy. Intra-operative</p><p>pain, presence of eye movements and complications of anaesthesia were monitored. Bleb leak and ptosis</p><p>were assessed postoperatively. Patient discomfort was assessed intraoperatively and 24 hours</p><p>postoperatively using a standardized verbal descriptive chart with 0 to 4 pain scoring levels.</p><p>Results: Eighty patients underwent sub-conjunctival anaesthesia for trabeculectomy. Sixty-eight (85%)</p><p>patients remained comfortable throughout the procedure. Only 3 (3.75%) patients required supplemental</p><p>subconjunctival anaesthesia block during surgery, while 7 (8.75%) patients required a facial block. Two</p><p>(2.5%) patients needed retrobulbar block. No surgery was postponed and none of the patient required</p><p>general anesthesia. Most common complication noted was chemosis of the conjunctiva (70%). In two cases</p><p>(2.5%) it interfered with the surgery and the surgery time was prolonged. Small sub-conjunctival</p><p>hemorrhage developed in 43 (53.75%) patients; however, this did not interfere with the surgery. No case of</p><p>postoperative bleb leak and ptosis was noted.</p><p>Conclusion: The technique of subconjunctival anaesthesia is safe, effective, tolerable, and convenient. It</p><p>is not associated with any remarkable postoperative complications because it is performed under direct</p><p>visualization.</p></span></span></span> ER -
