title: Outcomes of 20-gauge transconjunctival sutureless vitrectomy.
abstract: OBJECTIVE
  To assess the effectiveness and safety of the 20-gauge transconjunctival sutureless vitrectomy system in vitreoretinal surgeries.
  
  
  METHODS
  The charts of 102 consecutive patients who underwent 20-gauge transconjunctival sutureless vitrectomy by 1 surgeon were retrospectively reviewed. The main outcome measures were intraoperative and postoperative complications and postoperative intraocular pressure and Snellen visual acuity relative to preoperative values. Patients were evaluated before surgery and 1 day, 1 week, 1 month, and 3 months postoperatively.
  
  
  RESULTS
  No trocar-related intraoperative complications were recorded. Two patients (2%) each required suturing of 1 sclerotomy because of leakage at completion of surgery. Mean preoperative visual acuity (in logarithm of the minimum angle of resolution units) was 1.1 ± 0.6. By 3 months after surgery, the mean visual acuity had improved to 0.8 ± 0.5 (P < 0.001). Mean preoperative intraocular pressure was 14.7 ± 5.1 mmHg. Mean postoperative intraocular pressure was 14.2 ± 5.5 mmHg (P = 0.48) at Day 1 and 14.6 ± 4.3 mmHg (P = 0.82) at Day 7 after surgery. Hypotony was present in 3 patients (3%) on the first postoperative day, but their intraocular pressure normalized spontaneously within 1 week. None of the patients developed postoperative endophthalmitis or retinal detachment.
  
  
  CONCLUSIONS
  Twenty-gauge transconjunctival sutureless vitrectomy is a safe and effective technique for the surgical treatment of a variety of vitreoretinal pathologies.
