title: [Traumatic macular hole and posterior vitreous].
abstract: We studied retrospectively the clinical features of 18 eyes of 18 patients with traumatic macular hole. The macular hole was elliptical with irregular edges in 17 eyes (94%) and its size ranged from 1/5 to 1/2 of the disc diameter. Posterior vitreous detachment was found in 3 eyes (17%); the vitreous was detached from the macula in only one of these 3 eyes. Commotio retinae, vitreous hemorrhage, hyphema, or choroidal rupture was also found in several eyes. These findings suggest that traumatic macular hole develops usually in the absence of posterior vitreous detachment and its pathogenesis is independent of the occurrence of posterior vitreous detachment. We speculate that blunt trauma-induced deformity of the eyeball or impact on the posterior pole provides a mechanical cause for the macular rupture.
