PURPOSE: To evaluate the feasibility, reliability and analgesia effect of topical anesthesia combined with subconjunctival anesthesia in anti-glaucomatous surgery.
METHODS: Two hundred and four cases (357 eyes) underwent anti-glaucomatous surgeries under topical anesthesia with 0.5% Alcaine eye drops combined with subconjunctival anesthesia with 2% Lidocaine. The analgesic effect was analysed with visual analogue pain scale.
RESULTS: Among all of 357 eyes, 62 eyes underwent peripheral iridectomy, 67 eyes underwent simple trabeculectomy, 167 eyes underwent compound brabeculectomy and 12 eyes nonpenetrating trabecular surgery. The effects of anesthesia were as follows: 304 eyes (85.2%) were painless (Grade I), 50 eyes (14.0%) were slight painful (Grade II), and 3 eyes (0.8%) were more painful (Grade III) during surgery. And no severe complications were observed in all the cases during surgery and postoperatively. Amaurosis fugax was not observed in the glaucoma patients at the late stage with narrow visual fields and poor visual ability.
CONCLUSION: Topical anesthesia combined with subconjunctival anesthesia is effective, safe and simple anesthesia alternative in routine anti-glaucomatous surgery, especially for the glaucoma patients at the late stage with narrow visual fields and poor visual ability. It is worthy of being applied widely.
