To evaluate 25-gauge transconjunctival sutureless vitrectomy for primary repair of rhegmatogenous retinal detachment.


A retrospective, non-comparative interventional case series including 37 consecutive eyes of 37 patients who underwent 25-gauge transconjunctival sutureless vitrectomy to repair primary rhegmatogenous retinal detachment was performed. Variables collected for the study were patient demographics, lens status, preoperative visual acuity, tear location, number of breaks and macular status. Outcome measures included single surgery anatomical success rate, final anatomical success rate, postoperative visual acuity, and surgical complications.


Thirty-one eyes were phakic and six eyes were pseudophakic states. Twenty eyes had superior quadrant retinal tear, thirteen eyes had inferior quadrant tear and four eyes had both. 25-gauge transconjunctival sutureless vitrectomy was performed with Constellation Vision System (Alcon laboratories, Inc.). At the end of surgery endolaser photocoagulation was performed. Tamponade materials were C3F8 gas (32 eyes), air (1 eye) and silicone oil (4 eyes). Twelve eyes underwent 360 degrees prophylactic barrier laser during surgery. The mean operation time was 58.92 minutes. The single surgery anatomical success rate was 94.6% (35/37). Two eyes with superior retinal tear underwent fluid-gas exchange in out-patient clinic, and the final success rate was 100%. The best corrected visual acuity improved form 1.07 LogMAR to 0.60 LogMAR (p<0.05) in macular off cases (21 eyes) and 0.29 LogMAR to 0.34 LogMAR in macular on cases (16 eyes) at 6 months. 2 eyes were sutured with 10-0 nylon due to wound site leakage. Postoperative complications were cataract progression (9 eyes), vitreous hemorrhage (2 eyes), transient hopotony (1 eye), and increased intraocular pressure (6 eyes). Most of them were controlled with or without medication but one eye with increased intraocular pressure required filtering surgery and thee eyes required cataract surgery. None of the patients had choroidal detachment and endophthalmitis.


Primary repair of rhegmatogenous retinal detachment using 25-gauge transconjunctival sutureless vitrectomy resulted in excellent final anatomical success rate and postoperative visual outcomes.
