Answer: Hypopyon with severe anterior uveitis, showing layering of leukocytes and fibrinous debris in the anterior chamber. May be sterile or infectious. An intense ciliary flush is seen. Most commonly seen in HLA-B27-positive patients with uveitis. Hypopyon may also be a presenting sign of malignancy (retinoblastoma and lymphoma).
