TitreReview: Evaluation of feasability, security and efficacy of tranconjunctival sutureless 25-gauge vitrectomy
Abstract Nr.127
ButLitterature review to evaluate feasability, security and efficacy of transconjunctival sutureless (TSV) 25-gauge vitrectomy
MéthodesReview of 5 major studies about outcomes of 25-gauge TSV on: epiretinal membrane (ERM), macular hole (MH), rhegmatogen and tractionnal retinal detachment (RRD, TRD), macular edema from vascular origin (MO) and persistant vitreous hemorrhage (VH).
RésultatsFollow-up varies from 15 to 60 weeks. Significant improvement of visual acuity is seen both globally and for each indication. Three studies showed significant decrease of intraocular tension on postoperative day 1 but complete resolution is seen after 1 week. Two studies used sclerectomy sutures during RRD or TRD cure. Mean intervention times were about 20 minutes, maximum of 30 and 75 minutes when combined with phacoemulsification with implantation. Rare complications were: spontaneously resolving choroidal detachments (0.7-3.8%), retinal detachments by iatrogen breaks (0.6-3%) and one broken vitreous cutter tip (0.6%). Most frequent complication was lens sclerosis. No endophthalmitis or conversion in 20-gauge vitrectomy occured.
ConclusionTwenty-five gauge TSV offers good feasability, safety and global efficacy profile. Prospective and controlled studies more specific to each indication are needeed to confirm its superiority over traditional 20-gauge vitrectomy. Technological improvements like rigidity, endoillumination and faster cutting speed are needed to increase safety and efficacy in more indications. In the meantime, 23-gauge TSV could be an interesting alternative in complex cases.
