SUMMARY
This paper describes a case of a patient with macular hole associated to vitreoretinal traction caused by corioretinal scar, that underwent a pars plana vitrectomy to release the traction.
After surgery a epiretinal membrane appeared and its contraction closed the borders of the hole, improving the visual acuity and metamorfopsia.
The development of a epiretinal membrane, spontaneous or provoked by stimulus (endodiatemy, endophotocoagulation or a gentle touch at the exposed pigmented epithelium) may lead to a closure of the hole that may cause an improvement of the visual function if the photoreceptors are viable in that site.
