Closure of idiopathic full-thickness macular hole after intravitreal c3f8 injection without vitreomacular traction release: a case report and review of literature.

BACKGROUND:The purpose of this study was to describe a successful closure of macular hole without release of vitreomacular traction after intravitreal perfluoropropane (C3F8) gas injection. CASE PRESENTATION:A 54-year-old woman was referred to our clinic with the history of declined vision after a period of distorted vision in her right eye. After dilated fundus examination and performing optical coherence tomography, a V-shaped vitreomacular traction complicated by full-thickness macular hole was diagnosed and she underwent pneumatic vitreolysis using intravitreal C3F8 gas injection. After 12 weeks, her visual acuity was significantly improved and fundus examination and optical coherence tomography revealed that the macular hole was completely resolved despite persisted vitreomacular traction. CONCLUSION:Intravitreal gas injection would be a promising option to manage idiopathic macular holes not only by releasing the vitreous traction on the macula but also through some not proven or even unknown mechanisms.
