Topical anaesthesia in Trabeculectomies
Sauder G , Jonas J. B.
Department of Ophthalmology and Eye Hospital Mannheim, Faculty of Clinical Medicine , University of Heidelberg, 68167 Mannheim, Germany
Objective: To evaluate possibility and efficiacy of topical anesthesia
for trabeculectomies combined with the use of 5-FU or Mitomycin.
Patients and Method: The prospective unicenter clinical interventional
trial included 10 consecutive patients. (Five patients with 5-FU, 5 patients
with Mitomycin). The patients received preoperatively Oxybuprocaine 0,4%
eye drops and cocaine hydrochloride 10%eye drops. To assess intraoperative
pain, each patient was asked immediately after surgery to quantitate his/her
pain using a 10 point pain rating scale. Additionaly they were asked to
compare the pain during surgery with the pain for placing an intravenous
needle and the pain during a dentist`s treatment.
Result: For allpatients, it was possible to perform the trabeculectomy
with topical anesthesia. The duration of surgery was 21,5 ± 3,37
min. (range 15 - 25 min.), preoperative IOP was 37,2 ± 18,62 mmHg
(Min.-Max.: 20 - 75 mm Hg) compared to 8 ± 4,47 mmHg (range 4-15
mmHg) postoperatively at day 1. Subjective pain score was 2,25 ±
1,23 on a 10 point scale ranging from 1-5 points. Compared with the pain
for placing an intravenous needle 6 out of 10 Patients quoted that the
pain during surgery was better and 4 patients quoted equal. All patients
stated that the pain during surgery was less than the pain at a dentists
treatment. Complications encountered so far, were a slight hyphema at
ay 1 postoperatively (n=1), and flattening of the anterior chamber postoperatively
(n=2).
Conclusion: Trabeculectomies combined with 5-FU or Mitomycin can
efficiantly and safely performed under topical anesthesia, with the advantages,
that the superior rectus muscle does not have to be grasped and fixated
anymore, and that the disadvantages of peribulbar or retrobulbar injections
disappear.
