Purpose: To evaluate the anatomical and functional outcomes of pars plana vitrectomy without adjuvant scleral buckling, prophylactic 360° endolaser photocoagulation, or perfluorocarbon liquid use for the treatment of primary uncomplicated rhegmatogenous retinal detachment.
Methods: Retrospective interventional case series of consecutive patients undergoing vitrectomy for noncomplex rhegmatogenous retinal detachment over a 10-year period. Main outcome measures included primary anatomical success rate, defined as retinal reattachment at final follow-up after a single operation, proportion of eyes achieving a final best-corrected visual acuity ≤ logarithm of the minimum angle of resolution 0.3 (≥ Snellen 20/40), and postoperative complications.
Results: With a mean follow-up of 31 months, primary anatomical success was achieved in 95.7% (89 of 93) of eyes. Final anatomical success, defined as retinal attachment at final follow-up without regard to additional procedures, was achieved in 98.9% (92 of 93). Final best-corrected visual acuity of ≤ logarithm of the minimum angle of resolution 0.3 (≥ Snellen 20/40) was achieved in 77.4% of eyes in the cohort. Postoperative proliferative vitreoretinopathy developed in 3.2% of eyes. No new retinal breaks developed postoperatively in the absence of clinically evident proliferative vitreoretinopathy.
Conclusion: Thorough pars plana vitrectomy alone, without adjuvant scleral buckling, 360° endolaser photocoagulation, or routine perfluorocarbon liquid use, yields high anatomical and functional success rates and low complication rates in the treatment of primary uncomplicated rhegmatogenous retinal detachment. In the absence of observable proliferative vitreoretinopathy, postoperative vitreous base contraction does not appear to be a clinically relevant phenomenon.
