Anterior Segment Optical Coherence Tomography Findings in Corneal Blood Staining

Corneal blood staining is a complication that usually occurs after total hyphema of prolonged duration, associated with increased intraocular pressure (IOP).1 An IOP >25 mmHg for >5 days may result in corneal blood staining. Its reported incidence is 2–11% of traumatic hyphema cases and even higher for total hyphema. Other causes include hyphema induced by intraocular surgery or bleeding in the anterior chamber due to other causes. In cases of total hyphema, the management should aim to prevent cornea staining, as it can cause vision loss due to corneal opacity, requiring corneal transplantation.2 Very rarely, corneal blood staining can occur at a low IOP.3 Anterior segment optical coherence tomography (AS‑OCT) features in corneal blood staining has been described as highly refractive particles in the stroma, infiltrated by red blood cell products.
