RESUMO
PURPOSE: To compare the safety and performance clinical outcomes of the 27-gauge (G) two-dimensional cutting vitrectomy probe versus a standard 25-G probe for retinal procedures. METHODS: In this large randomized prospective study, all candidates for epiretinal membrane or macular hole surgery were randomized to the 27-G group or 25-G group. Outcome measures included surgery time, changes in best-corrected distance visual acuity, intraocular pressure, and central macular thickness between baseline and 1-month and 3-month follow-up time points. Moreover, intraoperative and postoperative complications were evaluated as well as the rate of sutureless vitrectomy. RESULTS: A total of 463 patients were included in this study, 227 patients in the 27-G group and 236 patients in the 25-G group. A similar total surgery time was found between both groups ( P = 0.0911). Similar best-corrected distance visual acuity and central macular thickness changes were observed between baseline and the 1-month and 3-month follow-up visits. No significant differences were reported in intraoperative and postoperative complications rates. The rate of sutureless vitrectomy was 96.5% for the 27-G group and 91.1% for the 25-G group ( P = 0.0170). CONCLUSION: These results suggest that 27-G vitrectomy probe is similar to 25-G probe in surgery time and complications, while decreasing the need for vitrectomy sutures.

INTRODUCTION: Progressive outer retinal necrosis (PORN) is a rare but devastating infectious retinitis associated with varicella zoster virus (VZV) and responsible for severe visual loss. CASE REPORT: A 59-year-old man treated for generalized myasthenia with oral azathioprine and prednisone presented with severe unilateral necrotizing retinitis. Polymerase chain reaction of the aqueous and vitreous humors was diagnostic for VZV PORN. CONCLUSION: VZV PORN is a severe potential ocular complication of immunosuppression, prompting urgent diagnosis and appropriate treatment.
