Abstract:

Objective To evaluate the effects of 25G vitrectomy with sterile air tamponade in primary rhegmatogenous retinal detachment(RRD) surgery. Design Retrospective case series. Participants RRD cases who underwent 25G minimally invasive vitrectomy with three channels through the pars plana of ciliary body with sterile air tamponade were consecutively collected from Aug. to Dec. 2016. Methods Best corrected visual acuity(BCVA), intraocular pressure(IOP), slit lamp microscope, indirect ophthalmoscope, color fundus photography, color doppler ultrasound and optical coherence tomography (OCT) were performed before surgery. Patients were followed up after operation, and the BCVA, IOP, retinal reattachment and complications were observed. Main Outcome Measures BCVA, IOP, retinal reattachment and complications. Results At the last follow-up visit, the retina reattached in all 13 eyes (100%). Choroidal detachment occurred in 3 cases on postoperative day 3, which improved after oral prednisone. Postoperative BCVA was logMAR 0.63±0.43, which  improved significantly compared to preoperative value (Compared rank sum test, S=-34, P=0.005). At the last follow up visit, the average IOP was 15.95±4.12 mmHg, significantly different from pre-operative value(t=-2.65, P=0.02). Conclusion Short-term air tomponade combined with 25G vitrectomy can be used as an alternative choice for primary rhegmatogenous retinal detachment with tear located above and not exceeding 3 quadrants.
