Abstract |
PURPOSE To evaluate the efficacy and safety of partial fluid air exchange at the end of 23-gauge transconjunctival sutureless vitrectomy to prevent postoperative hypotony. METHODS: Fifty-five eyes in 49 consecutive patients who underwent partial fluid air exchange at the end of 23-gauge sutureless vitrectomy by a single surgeon at Gil Hospital between August 2007 and February 2008 were recruited for this study. Intraocular pressure (IOP), visual acuity and post-operative complications were evaluated. RESULTS: Surgical indications included proliferative diabetic retinopathy (n=31), epiretinal membrane (n=9), nondiabetic vitreous hemorrhage (n=5), vitreous opacities (n=3), and others (n=7). Two eyes showed hypotony (<6 mmHg) on postoperative day 1 and resolved within a week without any supplemental procedures. Other complications included choroidal detachment in 1 eye, hyphema in 1 eye, and transient IIOP in 2 eyes. In 38 eyes in which combined cataract surgery was performed, air bubble-related complications including iris capture by the IOL in 3 eyes (7.9%) and opacification of the posterior capsule in 11 eyes (28.9%) occurred. No case of retinal detachment or endophthalmitis was observed. The final best corrected visual acuity was 20/40 or better in 14 eyes (25.5%). CONCLUSIONS: The partial fluid air exchange shows promise as an effective and safe procedure for prevention of postoperative hypotony after sutureless vitrectomy. Air bubble-related complications after combined cataract surgery can be avoided by several techniques. |
