Abstract

Purpose

This study aimed to investigate the incidence of increased intraocular pressure (IOP) and the clinical course of traumatic hyphema.

Methods

We retrospectively reviewed the medical records of traumatic hyphema patients from March 2016 to January 2019. Based on whether the IOP exceeded 21 mmHg, the patients were divided into two groups: increased IOP (IIOP) hyphema grade, and intraocular damage. We compared the two groups based on sex, age, cause of trauma, IOP, visual acuity, follow-up period, and hyphema grade. The IIOP group was also divided into two groups: treatment continuation and treatment termination. We compared the two groups on the same aforementioned basis.

Results

Of the 181 eyes, 53 (29.3%) were in the IIOP group. The initial IOP (p < 0.001), hyphema grade (p < 0.001), rebleeding incidence (p = 0.011), and intraocular damage (p = 0.027) were statistically significant between the two groups. The treatment continuation group for IIOP had 11 (20.8%) eyes, and the age (p = 0.029) and intraocular damage (p = 0.010) were statistically different from the treatment termination group.

Conclusions

The incidence of increased IOP was 29.3%. Continuous treatment was needed in 20.8% of the increased IOP cases, and the age and intraocular damage were related.

Values are presented as the mean ± standard deviation or number (%) unless otherwise indicated.

IIOP = increased intraocular pressure; M = male; F = female; IOP = intraocular pressure; V/A = visual acuity; logMAR = logarithm of minimal angle of resolution; F/U = follow-up.
