  1. Outcome of 23-gauge sutureless transconjunctival vitrectomy for endophthalmitis Dr Colin S.H. Tan

  3. Introduction • Endophthalmitis is a potentially devastating eye infection • Postoperative endophthalmitis reported in between 0.04% to 0/12% of cases • Vitrectomy may be useful in treatment of endophthalmitis, especially with visual acuity of light perception or worse. • No previous report on use of 23-G sutureless vitrectomy to treat endophthalmitis

  4. Objectives • To review the feasibility and surgical outcomes of using 23G transconjunctival vitrectomy for the treatment of endophthalmitis

  5. Methods • Non-randomized, interventional case series study • All patients presenting with postoperative endophthalmitis over a 1-year period from April 2005 to March 2006 • Main outcome measures: intraoperative and posteroperative complications (hypotony, wound leak, chemosis)

  6. Results • Vitrectomy was performed on 6 patients (4 acute and 2 chronic endophthalmitis) • Mean surgical time 58.3 minutes (range 40 – 75) • Mean follow-up 13.2 months (range, 9 –17)

  7. Surgical outcomes • Thorough clearance of the vitreous base was achieved • No severe postoperative pain • No wound leak / hypotony • Mean IOP on 1st postoperative day was 17.3 mmHg (SD  3.4, range, 12 – 21 mmHg) • Mean IOP change-4.2 mmHg compared to the preoperative IOP (p=0.239)

  8. Visual outcomes • ≥ 20/40 in 5 of 6 patients (83.3%) overall • ≥ 20/40 in 3 of 4 patients (75%) with acute endophthalmitis • Final visual acuity (VA) significantly improved compared to preoperative VA (p=0.026)

  9. Characteristics of patients

  10. Discussion • Advantages of transconjunctival vitrectomy: • Reduced surgical time • Less postoperative discomfort • Shorter recovery time • Concern about postoperative hypotony due to sutureless sclerostomy • Able to clear vitreous base without difficulty using 23-gauge instruments

  11. Conclusion • 23-gauge transconjunctival vitrectomy can be performed safely for both acute and chronic endophthalmitis • Good final visual acuity • No cases of hypotony or severe complications
