Effect of 360° episcleral band as adjunctive to pars plana vitrectomy and silicone oil tamponade in the management of myopic macular hole retinal detachment.

Purpose: To report the effect of 360° scleral band in combination with pars plana vitrectomy (PPV) and silicone oil tamponade on the anatomical success and on the closure of macular hole (MH) in cases of myopic macular hole retinal detachment.
Methods: A retrospective consecutive interventional study from medical records on patients who had pars plana vitrectomy and silicone oil. with or without 360° scleral band for the treatment of retinal detachment associated with MH. The cases were operated in the period from February 2006 to May 2012. The included cases were classified into two groups: the first group with scleral band and the second group without scleral band. The primary anatomical success and optical coherence tomography patterns of MH closure were the main outcomes.
Results: After the first procedure, the overall success rate was 90.6% (in both groups). In 9.4%, there was recurrent retinal detachment. In the first group the success rate was 89.5%, and in 10.5% there was recurrent retinal detachment. In the second group 92.5% was success and 7.5% was recurrent retinal detachment. After the second interference, the success rate was 98.4% in both groups. Closure of MH was achieved in 45.2% in both groups. In the first group, there was closure of MH in 43.5%, while in 47.8% the hole remained open flat, in 4.3% the hole closed partially and in 4.3% there was macular scar. In the second group, MH closure was achieved in 47.4%, whereas in 52.6% the hole was open flat.
Conclusion: The use of 360° band in combination with pars plana vitrectomy and silicone oil offered no additional effect on either the anatomical success or the rate of MH closure in the management of myopic macular hole retinal detachment. Four patterns of MH were reported closed MH, partial thickness MH, open flat MH, and macular scar.
