Unprompted Closure of Spontaneous Macular Hole Secondary to Retained Subfoveal Perfluorocarbon Liquid.

Purpose: To report unprompted closure of spontaneous macular hole secondary to inadvertent subfoveal perfluorocarbon liquid (PFCL) after vitrectomy surgery. . We present a case of a retained large single subfoveal PFCL droplet following vitrectomy and silicone oil injection for subtotal rhegmatogenous retinal detachment that showed spontaneous release 3 weeks postoperatively, with subsequent development of full thickness macular hole (FTMH) which completely closed later on after silicone oil removal without internal limiting membrane peeling with marvelous anatomic and visual improvement after spontaneous closure of MH.

Conclusions: Different fates of subfoveal PFCL droplets may happen. Spontaneous release of subfoveal PFCL without surgical interference has rarely been reported.
