Q

What does percussion of the thyroid gland involve?

A
  1. Percuss downwards from the sternal notch.

  2. Soft bruit is indicative of incr. blood flow which is characteristic of the hyperthyroid goitre seen in Graves.
  3. You may beed to occlude venous return within the IVJ to rule out a venous hum
  4. Listen over the aortic area to ensure that the thyroid bruit is not, in fact, an outflow obstruction murmur conducted to the root of the neck.

  4. Feel the palms - sweat/dry?
  5. Look for peripheral tremor - Ask patient to stretch out their arms.
  6. Inspect the face - Exophthalmos, proptosis, hypothyroid features.
  7. Examine the eyes.
  8. Examine the thyroid and neck.

  4. Ensure both eyes can close!
64
Q

What is termed “proptosis”?

A

The eyeball appears to sit forward - best seen from above.

65
Q

Is it a problem if the eyes of the patient can’t close?

A

It is a medical emergency.

66
Q

What is the von Graefe’s sign?

A

Lid lag.

  1. Hold your finger high and ask the patient to look at it and follow it with their eyes as it moves (keeping their head still).
  2. Quickly move your hand downwards - in this way the patient is made to look upwards and then quickly downwards.
  3. Watch the eyes and the eyelids - do they move smoothly and together?
67
Q

How can proptosis be formally assessed?

A

Using Hertel’s exophthalmometer.

68
Q

What is the difference between proptosis and exophthalmos?

A

Exophthalmos is a severe form of proptosis.

69
Q

What happens in severe exophthalmos, in which patient can’t close his eyes?

A
  1. Corneal ulceration
  2. Chemosis - edema of the conjunctiva and sclera caused by obstruction of the normal venous and lymphatic drainage.
  3. Conjunctivitis
70
Q

What is termed “lid retraction”?

A

Upper eyelid is retracted such that you are able to see white sclera above the iris when the patient looks forwards.

71
Q

What causes lid retraction?

A

Caused by incr. tone and spasm of levator palpebrae superioris as a result of thyroid hormone excess.

72
Q

How do we call the sign of incr. tone and spasm of levator palpebrae superioris as a result of thyroid hormone excess?

A

Dalrymple’s sign.

73
Q

To sum up, what does the examination of the eyes in thyroid disease involve?

A
  1. Inspection
  2. Visual fields
  3. Eye movements
  4. Lid lag
74
Q

What are the common findings when examining the eyes in thyroid disease?

A
  1. Proptosis
  2. Exophthalmos
  3. Lid retraction
  4. Lid lag
75
Q

Thyrotoxicosis leads to proptosis and exophthalmos?

A

NO - Proptosis/exophthalmos may be seen in 50% of patients with Graves - HOWEVER, proptosis may persist once thyroid hormone levels have been normalized.

76
Q

What are the eye signs of thyrotoxicosis?

A
  1. Lid retraction

2. Lid lag

77
Q

What are the eye signs of Graves disease (Graves ophthalmopathy)?

A

  4. Lid retraction and lid lag ONLY when thyrotoxicosis is present
78
Q

What does visual blurring may indicate?

A

Optic neuropathy - Fundoscopy should be performed.

79
Q

Q

Why do we call it “10g monofilament”?

Because it is designed to bend under approximately 10g of pressure.
