Feline post‐sterilization hyphema

Management of traumatic hyphema.

Hyphema (blood in the anterior chamber) can occur after blunt or lacerating trauma, after intraocular surgery, spontaneously (e.g., in conditions such as rubeosis iridis, juvenile xanthogranuloma, iris melanoma, myotonic dystrophy, keratouveitis (e.g., herpes zoster), leukemia, hemophilia, von Willebrand disease, and in association with the use of substances that alter platelet or thrombin func...

Spontaneous hyphema associated with anterior uveitis.

Few reports have described hyphema in association with anterior uveitis. Five cases of anterior chamber haemorrhage are reported in patients with five different anterior uveitic entities: Reiter's syndrome, juvenile chronic arthritis, ankylosing spondylitis, idiopathic anterior uveitis, and herpes simplex. Hyphema has been reported in association with idiopathic non-granulomatous anterior uveit...

Changes in outflow facility in experimental hyphema.

To characterize the pathophysiology of hyphema clearance, we studied changes in the facility of outflow in experimental hyphema in freshly enucleated rabbit eyes. Hyphemas, with washed normal or sickled red cells (RBCs) (suspended in isotonic phosphate buffer to obtain a hematocrit value comparable to that of whole blood) and occupying 50% to 100% of the anterior chamber volume, caused a marked...
