yphema is blood that is grossly visible in the anterior chamber of the eye and can cause permanent vision loss. It is a rare

complication that usually occurs after ocular trauma. Spontaneous or nontraumatic hyphema may result from underlying

bleeding disorders, anticoagulation or antiplatelet medications, vascular malformations, ocular abnormalities, closed-angle

glaucoma, sickle cell anemia, acute leukemia, rheumatologic disorders, or lymphoma. Rarely, spontaneous hyphema may

present after non-ophthalmic surgery due to intra-operative heparin administration, coagulopathy, severe hypertension, or

during emergence from anesthesia. Here we present a case of a man with acute respiratory distress syndrome (ARDS) as a

result of Influenza B infection who underwent lung protective mechanical ventilation strategy, sedation, paralysis, and prone

positioning to assist with oxygenation. This is the first reported case of non-traumatic hyphema in a patient undergoing prone

positioning as part of the management of ARDS. We postulate that the patient’s thrombocytopenic state coupled with the

increased venous drainage pressure in the eyes from the face-down prone positioning likely led to his development of bilateral

spontaneous hyphemas. Positioning his head to the side normalized venous drainage pressure and allowed rapid reabsorption

of the anterior chamber blood. Hyphema should be considered a potential complication of prone positioning in patients with

ARDS, especially in patients with a concomitant bleeding diathesis. In our patient, early recognition and medical intervention

led to complete resolution. Ophthalmology evaluation and management is important for successful recovery.
