This is a non-comparative, prospective consecutive case series to evaluates the safety, efficacy and outcomes to established treat rhegmatogenous retinal detachment (RRD) using 27-gauge system and instruments in transconjunctival microincision vitrectomy systems (MIVS).
The study population consisted of patients who had undergone primary retinal detachment repair with primary PPV. A conventional three-port vitrectomy was performed in all patients using 27-gauge system instruments kit (Dorc Inc, Zuidland, The Netherlands), Bright Star Xenon Illumination System (Dorc Inc, Zuidland, The Netherlands) and Accurus vitreous retinal machine (Alcon Laboratories, Inc. Fort Worth, TX, USA). 27-gague system instruments used to perform the surgery.
The study included 14 eyes of 14 patients followed for a mean of 8 months. Pseudophakic RRD was present in all cases, two patients (14%) have history of blunt trauma, extensive lattice degeneration in 5 cases (36%), single tear was present in two patients (14%) and posterior capsule rupture was present in 5 cases (36%). On initial presentation, 10 eyes (71%) had macular involvement. Initial visual acuity was ≥20/40 in 2 eyes (14%), ≥20/400 in 2 eyes (14%), and < 20/400 in 10 eyes (72%). Intraoperative data are summarized in Table 4. All cases undergone to primary PPV with 27-gauge instruments and perfluorocarbon liquid was used in all cases. Internal tamponade was achieved with silicone oil in 4 eyes (29%) and C3F8 with a dilution of 14% in 10 eyes (71%). Reoperation for recurrent retinal detachment was performed in two cases. All cases that underwent initial silicone oil tamponade underwent a second operation for silicone oil removal by last follow-up visit in December of 2012. All retina were attached and all patients had a improvement of visual acuity (VA).
27-gauge in transconjunctival microincision vitrectomy systems (MIVS) for primary pars plana vitrectomy (PPV) were safety, efficacy with a VA recover in all samples of this study.
