INTRODUCTION: To report the safety and efficacy of ciliary sulcus implantation of Ahmed Glaucoma Valve (AGV) in patients with corneal decompensation risk.
METHODS: Cases with corneal decompensation risk in whom AGV were implanted included in this retrospective study. Patients’ preoperative intraocular pressure (IOP), best corrected visual acuity and the number of antiglaucomatous drops values were compared with the postoperative ones. Success criteria was defined as postoperative IOP within 5-21 mmHg and no loss of light perception.
RESULTS: Twenty-three eyes of 23 (16 male, 7 female) patients were included into the study. Mean age of the patients was 64.6±14.6 years and mean follow-up was 15.8±8.3 months. Preoperative mean IOP was reduced from 33.6±9.1 mmHg to 16.9±5.1 mmHg in the last follow-up (p=0.000). Preoperative mean antiglaucomatous drop values were 3.5±1.3. However, postoperatively it was 1.7±1.4 in the last follow-up (p=0.000). The rate of total success was detected as 78 %. Although postoperatively mean BCVA was not chaneged significantly one patient was lost his light perception. No decrease was observed in corneal clarity except one patient (4,3%). Postoperative complications were; bleb encapsulation (43%), hyphema (39%), tube occlusion(13%), choroidal detachment (8.7%), decompression retinopathy (8.7%) and corneal decompensation (4.3%).
DISCUSSION AND CONCLUSION: Ciliary sulcus implantation of AGV was found to be effective both in IOP and the number of antiglaucomatous drug decrease in short term. This technique could be preffered due to posterior chamber implantation in patients with corneal decompansation risk.
