Pars plana vitrectomy and silicone oil tamponade as a primary treatment for retinal detachment caused by macular holes in highly myopic eyes: a risk-factor analysis.

Objectives: To determine (i) the efficacy of silicone oil tamponade as a primary treatment for a retinal detachment (RD) resulting from a macular hole (MH) (MHRD) in highly myopic eyes, and (ii) identify variables associated with successful retinal re-attachment. Methods: We retrospectively reviewed 28 eyes of 26 high myopia MHRD patients in one hospital. All eyes had been treated with pars plana vitrectomy (PPV) and silicone oil tamponade (PPV/silicone oil tamponade). Binary logistic regression was used to determine the factor(s) influencing initial anatomical success. Results: The initial anatomical success rate was 75% (21 of 28 eyes); after silicone oil removal, the anatomical success rate was 96.4% (27 of 28 eyes). MH diameter was the only variable associated with initial anatomical success. Conclusion: PPV/silicone oil tamponade is a practical choice for treatment of MHRD in high myopia. While RDs occasionally re-occur after silicone oil treatment, these events are limited and can be managed with simple measures. A large MH is a risk factor for recurrent RD.
