  • Title: 25-gauge lens-sparing vitrectomy for stage 4A retinopathy of prematurity.
    Author: Kychenthal A, Dorta P.
    Journal: Retina; 2008 Mar; 28(3 Suppl):S65-8. PubMed ID: 18317348.
    Abstract:
    PURPOSE: To evaluate the feasibility of performing lens-sparing vitrectomies using 25-gauge instruments for the management of stage 4A retinal detachments in Retinopathy of Prematurity (ROP). METHODS: 13 eyes of 10 patients with stage 4A retinal detachments underwent a lens-sparing pars plicata vitrectomy. All patients were operated using a three port transconjunctival 25-gauge sutureless technique. The sclerotomies were made 0.5 to 1.0 mm posterior to the limbus through the pars plicata. Core vitrectomy and membrane peeling were performed. A partial fluid-air exchange was used at the end of the procedure in the majority of the cases. The anatomic status of the retina was determined by ophthalmoscopy during routine follow up visits or under general anesthesia. Per-operative complications were recorded. RESULTS: Eight of the infants were female and two were male. The average postmenstrual age at birth was 26.4 weeks and the average postgestational age at time of surgery was 39.3 weeks (range, 33-44). Three out of the 13 eyes (23%) had zone I ROP. With a mean follow-up of 17 months (range, 4-36) 12 out of the 13 eyes (92%) achieved successful retinal reattachment. One eye developed post operative hypotony with a small choroidal detachment that resolved spontaneously. CONCLUSIONS: Surgical intervention with a three port 25-gauge transconjunctival sutureless vitrectomy is an effective technique to attach the retina in patients with stage 4A retinal detachment in ROP.
