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 (p0.239)

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 (p0.026)

Characteristics of patients

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
