Traumatic ocular injuries can cause glaucoma, yet few studies have examined the outcomes in assault injuries. We performed a review to evaluate patient characteristics, prognostic factors, and outcomes in assault injuries resulting in glaucoma.
A retrospective review identified 200 patients with a confirmed diagnosis of traumatic glaucoma seen in 2009-2015 at University Hospital. Inclusion criteria were 1) patients intentionally harmed with malicious intent and 2) follow-up of at least one year. Exclusion criteria were trauma due to other causes (motor vehicle accident, falls, sports, other) and nonadherence to medications. Demographic and clinical data were recorded for: LogMAR visual acuity (VA), mechanism of injury, intraocular pressure (IOP), and number of glaucoma medications. Mechanism of injury was classified as blunt or penetrating. Overall success was an IOP of 6-21 at one year follow-up, further defined as absolute success (maintaining IOP with no medication) or qualified success (requiring medication). Failures were sustained pressures >21 or <6 in >3 visits, enucleation, or need for additional glaucoma surgery.
Nineteen patients met criteria (18 males, 1 female; mean age 42.8 years). Mean follow-up time since the trauma was 63 months. Physical assault (n=14) was the most common cause of injury (Table 1). 68.4% of the injuries were blunt compared to 31.6% penetrating. 42.1% required glaucoma surgery, such as tube shunts (87.5%) or trabeculectomy (12.5%). Twelve patients (63%) were overall successes with a mean IOP of 13.67 (p<0.05) at the 12-month follow-up. Five (41.7%) patients were absolute successes, while 7 (58.3%) patients were qualified successes. Seven patients were failures (37%) with a mean IOP of 30.57, even with glaucoma surgery and/or medication (Table 2). As for prognostic factors, initial IOP was outside the normal range of 6-21 (odds ratio 1.87 95% CI: 0.28-12.31) and presenting mean VA was worse at 2.05 or hand movements (odds ratio 4.29 95% CI: 0.39-47.63) in the failure group.
Post-traumatic glaucoma due to assault can be severe with significant loss of vision. However 63.2% were successfully controlled with treatment, and of those 41.7% were surgical successes. Visual prognosis is guarded but control of glaucoma is possible with surgical and medical interventions.
