No laboratory studies are routinely indicated in the diagnosis of central retinal vein occlusion (CRVO). In older patients, laboratory testing should be directed toward identifying systemic vascular problems. In young patients, laboratory testing may be tailored depending upon individual findings, to include the following:

  • Complete blood cell (CBC) count

  • Glucose tolerance test

  • Lipid profile

  • Serum protein electrophoresis

  • Chemistry profile

  • Hematologic tests

  • Syphilis serology

  • In addition, thrombophilic screening, activated protein C resistance, lupus anticoagulant, anticardiolipin antibodies, protein C, protein S, and antithrombin III may be completed.
