| description | Marie Jeremy B San Pedro,1 James Paul S Gomez,1 Edgar U Leuenberger1– 3 1Asian Eye Institute, Makati, Philippines; 2Department of Ophthalmology, University of the East Ramon Magsaysay Memorial Medical Center Inc., Quezon City, Philippines; 3Department of Ophthalmology, Ospital ng Makati, Makati City, PhilippinesCorrespondence: Marie Jeremy B San Pedro, Email mariejeremy.sanpedro@gmail.comPurpose: This study aimed to compare the success and complication rates among patients implanted with Ahmed Glaucoma Valve (AGV) using the short and long tunnel technique through retrospective chart review.Patients and Methods: We reviewed 54 charts of adult patients who underwent AGV implantation using a Short-Needle Track (SNT) or Long-Needle Track (LNT) technique. Intraocular pressures (IOP), Best Corrected Visual Acuity (BCVA) and number of medications were recorded pre-operatively, and at Day 1, 3, 7, Month 1, 3, 6 post-operatively. Treatment success, occurrence of Hypertensive Phase (HP), complication and procedures done after AGV implantation were compared between the two groups using one-tailed Z-test of proportions.Results: A total of 20 (LNT) and 21 (SNT) charts were included in the study. There was no significant difference between the median postoperative IOP, BCVA, and number of anti-glaucoma medications between the two groups at each time interval. The comparison between the occurrence of HP (P = 0.435) and success rates (P = 0.476) between the two groups yielded no significant difference. Flat/shallow anterior chamber (AC) was seen exclusively in three eyes (14%) in the SNT group (P = 0.039). There was one occurrence of plate exposure in the LNT group (P = 0.149).Conclusion: The LNT technique of AGV Implantation may be used as an alternative to the traditional SNT (with autologous graft). The long needle track offers the advantage reducing the risk of complications arising from shallow anterior chamber post-operatively.Keywords: glaucoma drainage device, Ahmed glaucoma valve, long needle track technique, short needle track technique |
