An unusual complication of blunt ocular trauma: A horseshoe-shaped macular tear with spontaneous closure.

ABSTRACT

A case of horseshoe‑shaped macular tear after blunt trauma with the course of the tear and the relevant findings obtained by spectral‑domain optical coherence tomography (SD‑OCT) is described. A 21‑year‑old man who had suffered blunt trauma 5 days previously visited our clinic complaining of vision loss in his left eye. Ophthalmic examination and SD‑OCT images revealed a horseshoe‑shaped macular tear. A month later at the second visit, the macular tear was found to have spontaneously closed. There have been many cases reported previously of the spontaneous closure of traumatic macular holes. A horseshoe‑shaped macular tear is an atypical clinical presentation. However, the mechanism of spontaneous closure is hypothetically as same as that for a macular hole. High‑resolution images and three‑dimensional maps taken with SD‑OCT can provide more details on macular diseases and are more useful than time‑domain OCT images.
