Questions Your Doctor May Ask - and Why!

During a consultation, your doctor will use various techniques to assess the symptom: Double vision. These will include a physical examination and possibly diagnostic tests. (Note: A physical exam is always done, diagnostic tests may or may not be performed depending on the suspected condition) Your doctor will ask several questions when assessing your condition. It is important to openly share any pertinent information to help your doctor make an accurate diagnosis.

It is also very important to bring an up-to-date list of all of your all medical conditions, medications including dosages, and names of numbers of any specialist you see.

  1. How long have you had the double vision?

    Why: to determine if acute or chronic.

  2. Is it unilateral or bilateral?

    Why: Unilateral double vision (i.e. double vision that persists when one eye is covered) is rare, but it can be encountered in dislocated lens (as associated with Marfan's syndrome), as well as in congenital double pupil, cataracts, astigmatism, corneal opacities and hysteria.

  3. Is the double vision intermittent or continuous?

    Why: Intermittent double vision may suggest myasthenia gravis or Eaton-Lambert syndrome.

  4. Are the two images side by side or one above the other?

    Why: Double vision is an early sign of eye muscle weakness and this question will help determine which eye muscles are weak e.g. if images are side by side the lateral or medial recti are responsible. If the images lie one above the other then superior or inferior oblique or superior or inferior recti may be involved.

  5. In which direction is there maximal image separation?

    Why: helps determine which pair of eye muscles are responsible. e.g. separation is greatest in the direction in which the weak muscle has its purest action.

  6. At the point of maximal separation, cover one eye and determine which image disappears?

    Why: e.g. if the outermost image disappears the covered eye is the one that is responsible for the double vision.

  7. History of head trauma?

    Why: may cause double vision by several different mechanisms e.g. damage to nerves to the eye muscles themselves or by orbital damage with eyeball displacement.

  8. Have you had a recent dental anesthetic?

    Why: may cause temporary double vision.

  9. Past medical history?

    Why: e.g. diabetes may cause cranial nerve palsies; thyroid disorders.

  10. Alcohol history?

    Why: e.g. Wernicke's encephalopathy due to Vitamin B1 deficiency may cause 6th nerve palsy and consequent double vision.

  11. Fever and chills?

    Why: may suggest orbital abscess, cavernous sinus thrombosis or rarely diphtheria.

  12. Headache?

    Why: may suggest brain stem tumor, cavernous sinus thrombosis associated with sinusitis, intracranial aneurysm or temporal arteritis.

  13. Symptoms of vertebrobasilar artery insufficiency?

    Why: e.g. nausea, vomiting, bilateral blurring of vision or blindness, double vision, dizziness and difficulty speaking.

  14. Symptoms of multiple sclerosis?

    Why: e.g. impaired vision, limb weakness, limb numbness or tingling, tremor of hands, dizziness.
