Secondary hemorrhage in traumatic 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...

Nerf gun eye injuries: traumatic hyphema.

Three unrelated patients attended the accident and emergency department with pain and blurred vision after ocular injury with a Nerf gun. Two were adults and one was a child, all of which presented within a 3 months' period. All three cases were found to have ≥1 mm of traumatic hyphema (pooling of blood in anterior chamber of the eye), indicating significant ocular trauma. The two adult patient...

Traumatic hyphema in children: risk factors for complications.

OBJECTIVE To identify risk factors associated with higher rates of ocular complications in children with traumatic hyphema. METHODS Consecutive inpatient records from July 1990 through December 1997 were retrospectively reviewed for all children (aged < or = 18 years) who were admitted to the Wilmer Ophthalmological Institute, Baltimore, Md, within 48 hours of a closed-globe injury leading to...

Effect of melanin on traumatic hyphema in rabbits.

OBJECTIVE To investigate the role of melanin in influencing the clearance of traumatic hyphema and in the incidence of rebleeds following the hyphemas. METHODS Hyphemas were induced in 30 eyes of New Zealand white albino rabbits using an Nd:YAG laser. A total of 3.75 mg of synthetic melanin suspended in 0.1 mL of balanced salt solution was introduced into the anterior chambers of 16 animals. ...
