Hyphema can lead to increased IOP and corneal blood staining. This is graded on the amount of blood in the anterior chamber. The risk of IOP elevation increases with the grade of the hyphema (Figure 8).11

Goal

Identify significant ocular injuries; protect the eye from further injury.

Minimum

Initiate teleconsultation with photographs.

Best

NOTE: Tranexamic acid for prevention of rebleeding in hyphema has not shown any benefit 13 but may be used in multitrauma patients if otherwise indicated.

Posterior chamber injury: Injuries to the retina and optic nerve as a result of blunt injury will result in vision loss. Findings may include decreased visual acuity, vision loss, loss of red reflex through the pupil, positive RAPD, or evidence of vitreous hemorrhage or retinal detachment on ultrasound evaluation.

Initiate real-time video telemedicine consultation.

 

4. EYELID LACERATION

Lid lacerations can result from either sharp or blunt trauma (Figures 9–11). As with other injuries, the primary concern with lid injuries is the possibility of underlying globe injury. Lid lacerations have a low incidence of infection (unless the causative factor is an animal or human bite). Any avulsed tissue should be preserved in saline and chilled, whenever possible, and sent with the patient—not discarded or debrided. Meticulous closure of eyelid structures with proper magnification is usually required to maintain lid function. If fat is visible in an eyelid laceration, this indicates violation of the orbital septum, a key anatomic barrier to infection. If prolapsed orbital fat is identified, appropriate antibiotic coverage is needed as well as expedited evacuation for surgical exploration and repair. Do not attempt to excise or suture exposed orbital tissue; this can lead to uncontrolled bleeding in the orbit.
