Abstract

PURPOSES: We evaluated the outcome of trabeculectomy using inferonasal bleb in diabetic retinopathy patients awaiting vitrectomy or on whom vitrectomy was performed.
METHODS
We retrospectively reviewed the medical records of patients who had undergone trabeculectomy with an inferonasal bleb from December 2002 to May 2005. Seven eyes had neovascular glaucoma secondary to the proliferative diabetic retinopathy, 6 eyes primary open angle glaucoma, and 4 eyes steroid induced glaucoma. We evaluated postoperative complication, intraocular pressure, the number of ocular hypotensive eye drops, and preoperative and postoperative best corrected visual acuity.
RESULTS
Mean follow-up period was 20.47+/-5.55 months. Most common complication was early ocular hypotony (4 eyes, 24%), but no blebitis and bleb associated endophthalmitis were observed. Mean intraocular pressure was reduced from 30.77+/-5.61 mm Hg preoperatively to 13.72+/-4.61 mm Hg at the most recent follow-up. The number of preoperative ocular hypotensive eye drops was 2.9+/-0.3 and that of postoperative eye dros was 1.4+/-1.0. The difference between these was statistically significant (p=0.000). Eleven eyes (61.11%) had a stable or improved visual acuity.
CONCLUSIONS
Trabeculectomy using an inferonasal bleb appears to be a safe and effective surgical option that may be helpful in certain clinical situations, such as medically uncontrolled glaucomatous eyes with expected vitrectomy or vitrectomized eyes.
