Abstract:
PURPOSE: To evaluate the incidence and risk factors for ocular hypertension (OHT) in traumatic hyphema within 7 days after trauma. METHODS: A retrospective case series study of 265 traumatic hyphema inpatients from 2010–2016. OHT was defined as intraocular pressure (IOP) that exceeded 21 mmHg using two consecutive measurements by a Goldmann applanation tonometer within 7 days after trauma. The subjects were divided into two groups (OHT group and non-OHT group). Age, sex, best-corrected visual acuity (BCVA), IOP, hyphema grade, presence of systemic disease, and past history of glaucoma were compared between the two groups. RESULTS: Of the 265 patients, 95 (35.8%) developed OHT after traumatic hyphema. Of those 95 patients, 70 (73.7%) developed OHT within 1 day after trauma; 18 (18.9%) developed OHT 2–3 days after trauma; and 7 (7.4%) developed OHT 4–7 days after trauma. Compared to the non-OHT group, the OHT group had a lower visual acuity (p = 0.018) and higher IOP (p < 0.001). In addition. if the hyphema grade was higher the incidence of OHT was significantly higher (p = 0.017). Using multivariate logistic regression analysis, the BCVA (p = 0.045) and hyphema grade (p = 0.006) were associated with the incidence of OHT in traumatic hyphema within 7 days after trauma. CONCLUSIONS: The incidence of OHT in traumatic hyphema within 7 days after trauma was 35.8%. The BCVA and hyphema grade were associated with the incidence of OHT within 7 days after trauma.
