Clinical characteristics of traumatic macular holes

Abstract

The clinical characteristics of 20 eyes of 20 consecutive patients with traumatic macular hole were studied retrospectively. The macular holes were elliptical with irregular edges in 19 eyes (95%) and ranged in size from 0.2 to 0.5 DD (disc diameter). Posterior vitreous detachment (PVD) was found in only 3 eyes (15%); the vitreous was detached from the macula in only one of these 3. Other conditions found in the 20 patients included commotio retinae, vitreous hemorrhage, hyphema, and choroidal rupture. These findings strongly suggest that most traumatic macular holes develop in the absence of PVD and that the pathogenesis is independent of the occurrence of PVD. We believe that the macular rupture (hole) is caused mechanically by the force of the impact on the posterior pole and the ocular deformity which result from blunt trauma.
