How do you examine for exophthalmos?

Diagnosing exophthalmos

  1. check how well you’re able to move your eyes.
  2. use an instrument called an exophthalmometer to measure how far your eyeball protrudes.
  3. arrange for a CT scan or MRI scan.
  4. arrange for a blood test to check how well your thyroid gland is working.

How is clinical proptosis measured?

Clinical methods for measurement of proptosis:  A) PLASTIC RULER: can measure proptosis from the lateral orbital rim to the corneal apex,holding the ruler parallel to ground.  B)LUEDDE’S EXOPHTHALMOMETER: has several advantages -notch confirms to lateral orbital rim.

What are the symptoms of exophthalmos?


  • pain in the eyes.
  • dry eyes.
  • eye irritation.
  • photophobia, or sensitivity to light.
  • lacrimation, or eye secretions, and shedding of tears.
  • diplopia, or double vision caused by weakening of the eye muscles.
  • blurred vision.
  • blindness if the optic nerve is compressed.

How do you know you have proptosis?

Proptosis can be confirmed with exophthalmometry, which measures the distance between the lateral angle of the bony orbit and the cornea; normal values are < 20 mm in whites and < 22 mm in blacks. CT or MRI of the orbits is often useful to confirm the diagnosis and to identify structural causes of unilateral proptosis.

How do you find the degree of exophthalmos?

An exophthalmometer is an instrument used for measuring the degree of forward displacement of the eye in exophthalmos. The device allows measurement of the forward distance of the lateral orbital rim to the front of the cornea.

What is the difference between exophthalmos and Proptosis?

Proptosis can describe any organ that is displaced forward, while exophthalmos refers to only the eyes. Proptosis can include any directional forward displacement.

How is eye protrusion measured?

Proptosis is measured using an exophthalmometer. This device takes a millimeter measurement of the distance between the anterior cornea and the temporal orbital rim for each eye. For an individual patient the measurement base is the distance between the two temporal orbital rim margins.

What is the difference between Exophthalmos and Proptosis?

What is treatment for thyroid eye disease?

The treatment options for vision-threatening problems in thyroid eye disease include corticosteroids or other anti-inflammatory medications, radiation and surgery. A combination of these may be necessary to protect vision.

What’s the difference between Exophthalmos and proptosis?

Does blepharospasm cause blindness?

In severe cases, the spasms may intensify to the point where the eyelids are closed several hours at a time. Although an individual’s vision remains unaffected, prolonged closure of the eyelids may cause a person to become functionally blind.

How can I tell if I have bilateral exophthalmos?

To identify exophthalmos, inspect the eye from the front, the side and from above. Exophthalmos is bulging of the eye anteriorly out of the orbit. Bilateral exophthalmos develops in Graves’ disease, due to oedema and lymphocytic infiltration of orbital fat, connective tissue and extraocular muscles.

How to diagnose bilateral exophthalmos with Graves disease?

Bilateral exophthalmos is associated with Graves’ disease, caused by abnormal connective tissue deposition in the orbit and extra-ocular muscles. 1. Ask the patient to keep their head still and follow your finger with their eyes 2. Move your finger through the various axes of eye movement (“H“ shape) 3.

What should an ophthalmologist consider when diagnosing exophthalmos?

In performing a thorough medical history and a review of systems, the ophthalmologist should consider orbital involvement secondary to systemic pathology. Past trauma and family history also may aid in the diagnosis. Evaluation of the patient with exophthalmos begins with a thorough ophthalmic and medical history.

When do you need a speculum for exophthalmos?

Evaluation of the patient with exophthalmos begins with a thorough ophthalmic and medical history. When concomitant sinus disease or an intranasal source is suspected, a speculum or endoscopic intranasal examination is warranted. Special emphasis on the duration and rate of progression of the patient’s signs and symptoms is essential.
