ABSTRACT
PURPOSE: To evaluate the efficacy and long-term prognosis of pars plana vitrectomy and Ahmed valve implantation for intractable glaucoma comorbid with retinal disorders. METHODS: A retrospective review of 34 eyes of 30 patients receiving pars plana vitrectomy and Ahmed valve implantation for intractable glaucoma comorbid with retinal disorders was performed. Preoperative and postoperative intraocular pressure (IOP) and visual acuity, the usage of IOP-lowering medications and postoperative complications, and surgical success rate were evaluated. RESULTS: IOP and the number of IOP-lowering medications showed a significant decrease after pars plana vitrectomy and Ahmed valve implantation, as compared to before surgery (p < 0.001). The success rate was 88%, 88%, 84% and 85% postoperatively at 1 month, 6 months, 1 year and 3 years respectively. The mean follow up period was 24.21 +/- 14.99 months. Complications related to surgery included hyphema in 2 eyes, recurrent corneal epithelial erosion and defect in 2 eyes, corneal ulcer in 2 eyes and vitreous hemorrhage in 4 eyes. Visual acuity improved in 14 eyes (41.1%), no changes in 13 eyes (38.2%) and decreased in 7 eyes (20.6%). CONCLUSIONS: Pars plana vitrectomy and Ahmed valve implantation for intractable glaucoma comorbid with retinal disorders show long-term efficacy in lowering IOP.

PURPOSE: To evaluate the clinical effect of amniotic membrane (AM) graft and drainage valve implantation for the treatment of bullous keratopathy combined with intractable glaucoma. METHODS: Total 15 patients (15 eyes) were analyzed who underwent the operation for bullous keratopathy combined with intractable glaucoma, from Feb. 2002 to Aug. 2003. Under retrobulbar anesthesia, Ahmed valve was implanted under the supratemporal conjunctiva and exposed valve was covered with AM. And then, AM graft was performed after lamellar keratectomy for treatment of keratopathy. Serial check of IOP, corneal status and complications were performed after operation and during follow up. RESULTS: Mean IOP at last follow up was 11 mmHg. Corneal epithelium was stabilized within 10days. No serious complication was found and the drainage tube was well positioned. Especially, there is no pain in all cases. CONCLUSIONS: AM graft and valve implantation was clinically effective method for treatment of bullous keratopathy, combined with intractable glaucoma.

1. Three cases demonstrating two forms of epithelial invasion of the anterior chamber are presented. In all the cases it is believed that inadequate wound closure was the main factor in the causation of the condition2. Differential and clinical diagnosis of epithelization of the anterior chamber is emphasized3. Preventive and therapeutic measures are suggested. (Summary)
ABSTRACT
Fifteen patients, 15 eyes with medically uncontrollable glaucomas and poor surgical prognoses underwent one-stage, single plate Molteno implatation without postoperative adjunctive systemic antifibrosis therapy. The Molteno implant procedures were successful in 12 (80%) of the 15 eyes. The visual acuity was improved in 2 eyes (13%), but worsened in 2 eyes (13%). Complications included hyphema in 5 eyes (33%), choroidal detachment in 4 eyes (26%), shallow anterior chamber in 3 eyes (20%), tube-iris touch in one eye (6%).
