title: Chronic cystoid macular edema and predictors of visual acuity.
abstract: Of 141 patients who had clinically significant cystoid macular edema (CME) following cataract surgery, 42 had a visual acuity of 20/200 or worse. Logistic regression demonstrated that of all the systemic and ocular factors studied, the best predictors of visual acuity of 20/200 or worse were the presence of iris in the wounds (odds ratio = 2.86, P = .011) and a fluorescein angiogram grade of 4 (odds ratio = 2.91, P = .0076). Entering into the logistic regression variables such as integrity of the posterior capsule, iritis, vitreous in the wound, or type of intraocular lens did not significantly improve the ability of the model to predict which patients would have poor visual acuity. This study suggests that iris incarceration in the wound may have a more important association with poor vision in patients with chronic postsurgical CME than previously thought.
