Ocular Trauma
Inflammation
Acute and chronic inflammation are common sequelae of ocular trauma. Severe uveitis may mimic infectious endophthalmitis. Fibrin membranes on the iris lead to synechiae formation, pupil seclusion, and miosis; these are treated with pupil-enlarging maneuvers (described previously in the section Small Pupil). In an inflamed eye, a peripheral iridotomy can help prevent pupillary block glaucoma. Inflamed uveal tissue bleeds upon the slightest manipulation. OVDs should be used liberally to protect the corneal endothelium and to improve visualization into the anterior segment. Postoperative IOP elevation is typical and is exacerbated by the use of OVDs. Control of inflammation warrants cycloplegia as well as intensive topical and possibly oral corticosteroid therapy.
