Abstract
Background: The aim of this study is to provide a quantitative evaluation of the blood-aqueous barrier (BAB) in patients with ocular blunt trauma and evaluate its association with intraocular pressure (IOP) elevation. Methods: This is a prospective case-control study, and the following 3 groups were included: elevated IOP (45 patients with an elevated IOP secondary to ocular blunt trauma), normal IOP (27 patients with a normal IOP after ocular blunt trauma), and healthy controls. The main outcome measures were IOP and BAB function evaluated using a laser flare-cell meter (LFCM). Results: Patients had significantly higher flare intensities and cell counts than the normal controls (both p < 0.001), and the elevated-IOP group displayed even higher LFCM readings than the normal-IOP group. Aqueous flare and cell readings were positively correlated with IOP (r = 0.529 and 0.590, respectively, p < 0.001). LFCM readings in the elevated-IOP group were still significantly high even on postraumatic day 120 following anti-inflammatory treatment. Conclusion: BAB dysfunction occurred following ocular blunt trauma. Eyes with an elevated IOP displayed a more seriously disturbed BAB and a longer recovery course. Examination with a LFCM provides insight into the pathophysiology of IOP elevation and assists in making decisions concerning anti-inflammatory treatment during follow-up.
