Combined posterior contusion and penetrating injury in the pig eye. II. Histological features.

Br J Ophthalmol 1982 Dec;66(12):799-804

The main histological features observed after an experimental posterior contusion injury in the pig eye were haemorrhage from the choroidal vessels into the subretinal space and into the vitreous, uveal vessel dilatation, and an inflammatory reaction. These changes resolved during the first 2 weeks, and the subretinal haemorrhage was replaced by a fibrocellular membrane. The addition of a posterior penetrating injury resulted in fibrocellular proliferation at the wound site 6 days after injury and in formation of vitreoretinal traction membranes and subsequent traction retinal detachment. Posterior vitreous separation did not occur.
