Indirect choroidal rupture secondary to blunt ocular trauma. A review of eight eyes

We retrospectively studied eight eyes of seven patients sustaining indirect choroidal rupture secondary to blunt trauma. Clinical and fluorescein angiographic findings were reviewed. The ruptures were single in five eyes and multiple in three eyes. Four eyes contained macular ruptures, and three eyes contained extramacular ruptures. Peripapillary ruptures were noted in three eyes. Three eyes developed subretinal neovascularization as a complication. Location of the rupture but not visual acuity at presentation was predictive of visual outcome. All ruptures were concentric with the optic nerve and vertically oriented, consistent with a break in Bruch's membrane and an associated tethering effect by the optic nerve.
