Topical anesthesia for penetrating trabeculectomy
Sauder G; Jonas JBGraefe's Archive for Clinical and Experimental Ophthalmology 2002; 240: 739-742
PURPOSE: To evaluate the efficacy and clinical practicability of topical anesthesia compared to retrobulbar anesthesia for penetrating trabeculectomy. METHODS: The prospective single-surgeon clinical interventional trial included 20 consecutive patients, who were randomly distributed into a topical anesthesia group (n = 10) and a retrobulbar anesthesia group (n = 10). In the topical anesthesia group, patients received preoperatively oxybuprocaine 0.4% eye drops and cocaine hydrochloride 10% eye drops. Patients in the retrobulbar group received 5 ml mepivacaine 2% injected into the retrobulbar space. To assess intraoperative pain, each patient was asked immediately after surgery to quantitate his/her pain using a ten-point pain rating scale. RESULTS: The topical anesthesia group and the retrobulbar anesthesia study group did not vary significantly in duration of survey (21.5 ± 3.37 versus 20.2 ± 4.46 minutes, p = 0.31), preoperative intraocular pressure (IOP; 32.2 ± 14.62 versus 30.6 ± 12.33 mmHg; p = 0.22), postoperative IOP (8.0 ± 4.47 versus 9.12 ± 3.13 mmHg; p = 0.64), subjective pain score by the patient (2.25 ± 1.23 versus 2.33 ± 1.08 relative units; p = 0.71), and practicability score by the surgeon (2.24 ± 1.76 versus 2.56 ± 1.58; p = 0.82). CONCLUSIONS: In view of its clinical feasibility and its minimally invasive character, topical anesthesia may be an option for penetrating trabeculectomy.
