Silicone oil injection after failed primary vitreous surgery in severe ocular trauma

In 42 cases of retinal detachment following a failed vitrectomy (a procedure to remove the contents of the vitreous chamber of the eye), the re-attachment of the retina was successful in 50 percent of the cases. Twenty-eight percent had vision of 5/200 or better. Many patients who had vision of 5/200 or better at six months lost acuity in the three years following, usually due to further retinal detachments or swelling of the cornea. Only 12 percent of the patients had vision of 5/200 or better at the last examination.
