Abstract:
Traumatic hyphema can induce increased intraocular pressure through various mechanisms. In this report, we provide imaging evidence of pupillary block secondary to traumatic hyphema. Ultrasound biomicroscopy may be a valuable imaging modality for assessing anterior chamber anatomy when visualization is obscured by hyphema, helping to guide the surgical approach for evacuation.
