This cohort study was designed to evaluate risk factors for the development of posttraumatic glaucoma after ocular contusion.
Data from the United States Eye Injury Registry (USEIR) were obtained from a total of 6021 patients who experienced blunt ocular contusion. Logistic regression was used to evaluate the association between these baseline structural and functional ocular characteristics and posttraumatic glaucoma. Odds ratios with 95% confidence intervals were obtained.
The 6-month incidence of developing posttraumatic glaucoma was 3.39%. The development of glaucoma was independently associated with: advancing age (OR = 1.02; 95% CI = 1.02, 1.03), visual acuity worse than 20/200 (OR = 1.92; 95% CI = 1.19, 3.10), iris injury (OR = 1.60; 95% CI = 1.05, 2.44), lens injury (OR = 1.86; 95% CI = 1.11, 3.11), hyphema (OR = 2.23; 95% CI = 1.40, 3.54), or angle recession (OR = 1.71; 95% CI = 1.00, 2.90).
This study provides an estimate for the risk of developing glaucoma after ocular contusion in a large cohort of patients and has determined several independently predictive factors that were significantly associated with the development of posttraumatic glaucoma including poor initial visual acuity, advancing age, lens injury, angle recession, and hyphema.
