Hi osimo,
I found a list that will be of interest to you. In answer to your
question about head injury - yes it could be a cause of a head injury.
Central Retinal Vein Occlusion: Systemic Considerations
http://www.nova.edu/~jsowka/vascocc.html
Hypertension*
Diabetes mellitus*
Cardiovascular disease (some studies feel that the CRVO pt. Has no
greater incidence of cardiovascular disease than age matched controls)
Hyperviscosity syndromes:
Hypergammaglobulinemia, paraproteinemia, hyperfibrinogenemia, cryofibrinogenemia
Hyperviscosity states:
Malignancy, paraproteinemia, nephrotic syndrome, chronic lung disease,
Behcet's disease.
AIDS:
Infectious vasculitis
Collagen vascular disease:
Lupus and lupus-like diseases- Antiphospholipid antibodies, common in
these diseases, interfere with endothelial cells and prevent
interaction with platelets and anticoagulants, thus increasing
thrombus formation.
Primary antiphospholipid antibody syndrome
Same reasons as collagen vascular disease, but phenomenon is primary entity
Syphilis:
Infectious vasculitis
Sarcoid:
Localized vein inflammation
Polycythemia (hyperviscosity)
Leukemia (blood dyscrasia-hyperviscosity)
Autoimmune disease:
Infectious vasculitis and antiphospholipid antibodies
Oral contraceptive use (causes a potentially hyperviscosity state)
Head injuries
Carotid artery disease:
Slow flow and increased viscosity
Hyperlipidemia
Mitral valve prolapse
Migraine
Pressure profusion abnormalities at ONH
Retrobulbar compression
Sickle cell disease (blood dyscrasia- hyperviscosity) - elevated hematocrit
Increased erythrocyte aggregation
Decreased plasma volume (causing increased viscosity and erythrocyte aggregation)
Best regards,
