To report our findings in a case with bilateral horseshoe-shaped macular tears. Both eyes of a 68-year-old woman developed horseshoe-shaped macular tears in the absence of vitreous traction due to prior vitrectomy in one eye and a posterior vitreous detachment in the other eye. Vitrectomy with the inverted internal limiting membrane flap technique led to a successful closure of the macular tear bilaterally, and an improvement of her visual acuity in both eyes. The cause of horseshoe-shaped macular tear was most likely due to a retinal rupture from a blunt trauma.
