The list of diagnostic tests mentioned in various sources as used in the diagnosis of Double vision includes:

    • Visual acuity

    • Look for associated proptosis (forward displacement of the eyeball). If bilateral may suggest hyperthyroidism from Graves disease. If unilateral
    • Look for associated chemosis (swelling of the conjunctiva), ecchymoses (bruising around the eye) or periorbital edema (swelling of the eyelids) which can suggest cavernous sinus thrombosis
    • If unilateral chemosis (swelling of the conjunctiva), ecchymoses (bruising around the eye and proptosis (forward displacement of the eyeball) consider arteriovenous aneurysm
  • Physical examination

  • Blood tests
  • Radiological investigations
    • Skull X-Ray and Sinus X-Ray - if fever is present.
    • CT Brain, sinuses and orbits - if fever is present or suspect orbital or brain tumor.
