Vitrectomy and autologous platelet concentrate for the treatment of idiopathic macular holes

Purpose To assess the efficacy of pars plana vitrectomy,autologous platelet concentrate and gas tamponade for the treatment of full-thickness idiopathic macular holes. Methods The procedures consisted of pars plana vitrectomy with removal of posterior cortical vitreous，air-fluid exchange, instillation of autologous platelet concentrate onto the posterior pole and 20%～30%SF6 tamponade,were performed in treating 6 eyes of 6 patients with idiopathic macular holes. The patients were instructed to lie in a supine position for l hour after surgery,then adviced to remain in a facedown position for 2 weeks. Results Flattening of the surrounding retina and closure of the hole were achieved postoperatively in all the 6 affected eyes.Visual acuity improved two lines or more in 5 eyes (83.3%).Four eyes(66.7%)reached a postoperative visual acuity of 0.3 or more. Retinal detachment ocurred in one eye owing to peripheral new hole formation. Conclusion Pars plana vitrectomy, autologous platelet concentrate and gas tamponade for the treatment of full-thickness idiopathic macular holes are able to close macular hole and improve the visual acuity.
