Abstract

To evaluate the effect of trabeculectomy on glaucoma following penetrating keratoplasty, we analyzed surgical results of patients who had taken trabeculectomy because of glaucoma associated with penetrating keratoplasty during the last two years. We evaluated success rate of trabeculectomy and possible causative factors which evoked filtering surgery failure. Mean follow-up period was about one year (11.98+/-3.2months) after trabeculectomy. Among the eyes with trabeculectomy, 61.9% maintained their intraocular pressure below 21 mmHg until last visit. Early elevation of increased intraocular pressure after keratoplasty was the only risk fator of filtering surgery which was stastically significant (P<0.05). However, aphakic or pseudophakic eyes, eyes with inflammatory disease and large donor trephine size were also estimated for possible risk factors. Corneal graft failure was single most common complicagion (5 eyes, 23.9%) after trabeculectomy. In conclusion, we think that early filtering surgery on the glaucomatous eyes associated with keratoplasty possible improved the surgical results. However, further studies to increase success rate of filtering sugery and to reduce graft failure rate, were warranted.
