Purpose: To report a macular hole secondary to an idiopathic epiretinal membrane in a 14- year- old girl. Design: Interventional case report. Methods: A 3- year- old girl who failed a public visual- screening test was examined. Since then, she had been followed- up for her epiretinal membrane, which began to peel spontaneously in the left eye for 11 years until a macular hole was observed. She was treated by vitrectomy and membranectomy, and the membrane was histologically examined. Result: The macular hole was successfully closed, and her visual acuity improved. The membrane appeared to have a homogenous structure and contained no cells. Conclusions: The juvenile idiopathic epiretinal membrane sometimes peels spontaneously. However, long- term follow- up is needed because vitreous traction of the membrane by intraocular aging change may result in a macular hole.
