VITRECTOMY FOR MACULAR DETACHMENT ASSOCIATED WITH OPTIC-NERVE PITS

Objective. To describe the pathogenic mechanism for a central retinal detachment in eyes with a pit of the optic disc. Design. Three patient s with macular detachment associated with optic nerve head pits were p rospectively controlled following pars plana vitrectomy. Methods. Thre e cases of macular detachment associated with congenital optic nerve p it were treated with pars plana vitrectomy and air-fluid exchange and sulphur hexafloride (SF6) gas injection. During vitrectomy posterior h yaloid removal caused visible traction on the elevated retina, when th e hyaloid detached. Removing the posterior hyaloid resulted in reattac hment of the macular and an increase in the visual acuity without lase r treatment. Conclusion. We recommend the removal of the posterior hya loid face during pars plana vitrectomy in patients with central macula r detachment associated with a pit of the optic disc.
