ABSTRACT

Hyphema (hemorrhage in the anterior chamber of the eye) may present in open or closed-globe eye trauma, may be complicated by ocular hypertension (25%) and may be accompanied by other injuries. Clinical features of eyes with hyphema and presence of additional injuries were identified. Method: Ocular trauma cases evaluated between 1995 and 2003 were reviewed, and the rate of hyphema was determined. Rates and confidence intervals (CI) of ocular hypertension (intraocular pressure > 21 mmHg), open-globe injury, visual deficiency (> 1 grade) and additional injuries in zones II and III were identified in hyphema patients. Results: 67 of 576 patients had hyphema (11.6%); their age averaged 25.1 years, 85.1% were male. Mean intraocular pressure was 13.1 mmHg (SD ± 5.5); four eyes had ocular hypertension (5.9%, 95% CI 0.3-11.5), 20 had open globe injury (29.9%, 95% CI 19.7-40.1), 51 had visual deficiency (76.1%, 95% CI 65.9-86.3), 43 had additional injuries in zone II (64.2%, 95% CI 52.7-75.7) and 19 had zone III injuries (28.3%, 95% CI 17.5-39.1). Discussion: Rates of visual deficiency and additional injuries in zones II and III overtook that of ocular hypertension, which was lower than reported. Identifying an evident ocular injury should not substitute integral ocular evaluation, which could be achieved by using the standardized classification of ocular trauma.
