Abstract Details


To report the surgical outcome of L-shaped macular buckle combining posterior vitrectomy with gas in recurrent myopic macular hole retinal detachment


Prospective consecutive case series, single centre


Consecutive cases of recurrent myopic macular hole retinal detachment with or without choroidal detachment were recruited since Nov 2013 at a tertiary eye hospital in Hong Kong. They all underwent L-shaped macular buckle as described by Parolini B et al combining with posterior vitrectomy and gas tamponade (20% SF6) by single surgeon. L-shaped buckle was prepared using Labtician 507 oval sponge and malleable titanium stent. Internal limiting membrane (ILM) peeling was confirmed intraoperatively using ILM blue stain. Preoperative visual acuity, axial length, retinal status and postoperative visual acuity, macular and retinal status, multifocal electroretinogram and optical coherent tomography findings, choroidal circulation as assessed by indocyanide green fundus imaging were reported. Cases with at least 3 months follow up were analyzed.


Three out of four cases had retina reattached. Among them, two out of three macular holes were closed. All have improved visual acuity and no diplopia encountered. The failure case was suffered from posterior vitreo-retinopathy with retina reattached after silicone oil injection


L-shaped macular buckle combined with posterior vitrectomy and gas tamponade may be a feasible option for recurrent myopic macular hole retinal detachment in addition to traditional silicone oil tamponade.
