Hyphema occurring after ocular paracentesis has been described as a classic feature of Fuchs' heterochromic uveitis (FHU) (Amsler's sign). We describe a case of hyphema occurring after peribulbar anesthesia in a patient with FHU. The bleeding occurred before the surgery began. Although the occurrence of this phenomenon does not preclude successful surgical outcomes, topical anesthesia may lower the risk preoperatively.
