Subretinal perfluorocarbon liquid for dissection of proliferative vitreoretinopathy.

Proliferative vitreoretinopathy (PVR) is a frequent condition following complex retinal detachments or trauma, and subretinal PVR is a common cause of retinal redetachment. Subretinal PVR removal is challenging and may require creating multiple or large retinotomies, making manipulation of the retina difficult and sometimes hazardous. We propose a novel surgical technique that may facilitate subretinal removal of PVR.

A modified technique for extracting a dislocated lens with perfluorocarbon liquids and viscoelastics.

The authors describe a modified technique for extraction of a dislocated crystalline lens or large and hard lens fragments displaced into the vitreous cavity. An ophthalmic viscosurgical device was used around and on top of the heavy liquid bubble to keep the lens centered and less mobile for easier phacofragmentation or removal by the cutting-suction probe. This technique was used in 10 eyes, including cases of traumatic dislocation and Marfan syndrome, with excellent anatomical results and no complications that could be attributed to the surgical technique.

The uvea in ocular trauma.

The uveal tissue is frequently affected in ocular trauma. Its anatomic and physiologic changes are responsible for many of the early and late clinical manifestations seen in the traumatized eye. Together with the retina, the uvea may be the tissue most responsible for the final visual and functional outcomes of the eye.
