Repeat vitrectomy successfully closes macular holes in 83% of patients after initial surgery failure. Visual acuity improved in over half, suggesting repeat surgery is a viable option for persistent macular holes.

Area of Science:

  • Ophthalmology
  • Retinal Surgery

Background:

  • Macular holes can persist after initial surgical repair.
  • Reoperation rates for failed macular hole surgery are significant.

Purpose of the Study:

  • To determine the anatomic and visual success rates of repeat vitrectomy for patients with failed primary macular hole surgery.

Main Methods:

  • Retrospective analysis of 48 patients undergoing repeat vitrectomy.
  • Standardized protocol using transforming growth factor-beta 2 (TGF-beta 2) and perfluoropropane gas.
  • Visual acuity measured using Early Treatment Diabetic Retinopathy Study (ETDRS) guidelines.

Main Results:

  • Anatomic closure achieved in 83% of reoperated eyes.
  • Visual acuity improved by ≥3 ETDRS lines in 52% of patients.

  • Final visual acuity of ≥20/63 and ≥20/40 achieved in 54% and 25% respectively.
  • Preoperative visual acuity >20/80 was the only factor predicting better final visual acuity.

    • Conclusions:

    • Repeat vitrectomy is effective in achieving macular hole closure in previously failed cases.
    • Visual improvement is frequent but lower than in primary surgeries.
    • Repeat vitrectomy should be considered for persistent macular holes.
