Definition
Thyroid eye disease(TED) is an autoimmune disease
caused by the activation of orbital fibroblasts by
autoantibodies directed against thyroid receptors.
TED is a rare disease, which had an incidence rate of
approximately 19 in 100,000 people per year .

Introduction
These changes havealso been called as :
Endocrine Exophthalmos
Malignant Exophthalmos
Dysthyroid Ophthalmopathy
Ocular Graves’ Disease (OGD)
Thyroid Eye Disease (TED)
5.
Introduction
Incidence of ThyroidEye Disease depending on thyroid
disorder
Hyperthyroidism-90%
Primary hypothyroidism-1%
Hashimoto thyroiditis-3%
Euthyroid -6%
6.
Thyroid gland
Location: Anteriorneck beneath the larynx
Endocrine gland and highly vascular and supplied by
autonomic nervous system.
Has over a million follicles that secrete thyroglobulin, a
precursor of the thyroid hormones, On activation the
thyroglobulin is re-absorbed, converted into the
thyroid hormones triiodothyronine (T3) and thyroxine
(T4),
Hyper Thyroid
Hyperthyroidism isa condition that results from an over-
secretion of thyroid hormones.
It is usually caused by an autoimmune disease known as
Graves’ disease,
Common causes :
Thyroiditis
Toxic adenomas,
Toxic nodular/ multinodular goiters
Thyroxine overdoses
Excess iodine dietary intake.
9.
Hypo Thyroid
Hypothyroidism isdue to an underactive thyroid gland and
results in a deficiency of thyroid hormones.
Thyroid hormones are essential for normal development
between birth and puberty and a deficiency causes
irreversible mental retardation.
Hypothyroidism can be caused by Hashimoto’s thyroidism,
Pathophysiology
TED being anautoimmune disease with orbital fibroblast as the
primary target inflammatory attack and the EOM are secondarily
involved
Also the target antigen is shared b/w thyroid follicular cells and
orbital fibroblast
The activated T cells acts on fibroblast – adipocyte lineage with in
orbit and will stimulate adipogenesis, fibroblast proliferation and
GAG synthesis as a result of which EOM are enlarged due to
infiltration and odema
13.
Pathophysiology
There is anincrease in the volume of the orbital contents,
particularly the muscles, which can swell to eight times their
normal size.
There may be a secondary elevation of intraorbital pressure, and
the optic nerve may be compressed.
Later muscle fibres eventually leads to fibrosis, which exerts a
tethering effect on the involved muscle, resulting in restrictive
myopathy and diplopia
Common Risk Factors
Female(4-6 times) and middle aged
Smoking (no of cigarettes per day)
H/O auto immune thyroid disorder
HLA-DR3 and HLA-B8 positive
Genetic predispsition
Life style

33.
Rare Associations

system
34.
Differential Diagnosis
Orbital orPreseptal cellulitis
Carotid-cavernous fistula
Idiopathic orbital inflammation (Pseudotumour)
TED must be ruled out in all cases of B/L proptosis
35.
Disease Course andPhases
The pattern of the disease follow the Rundle’s curve which
describe the plot of orbital disease severity against time
1.Initial phase- inflammatory phase duration may last from 6 –
18 months with orbital and periorbital signs i.e. proptosis and
retraction.
2.Static phase- decrease in the inflammatory phase and
minimal improvement.
3.Quiescent phase- gradual improvement with improved
motility and retraction of the muscles
Investigations (IMAGING)
USG (BSCAN)
To visualize the orbital structures and determining recti muscle
enlargement.
low cost, lack of ionizing radiation and relatively short
examination time
CT/MRI
Detects proptosis, muscle thickness, thickening of optic nerve
and anterior prolapse of the orbital septum (due to excessive
orbital fat and/or muscle swelling), erosion of wall of orbit,
Basic Investigations
1. Correctedvisual acuity and Refraction
2. Color vision testing
3. Examination for an afferent pupillary defect
4. Extraocular muscle motility examination
5. Measurement of the lid fissure height in primary
gaze
46.
Basic Investigations
1. Measurementof upper and lower scleral show,
2. Exophthalmometry to detect proptosis
3. Slit-lamp biomicroscopy to assess the tear film and
fluorescein pattern
4. Fundus examination to detect optic disc swelling or
pallor.
47.
Treatment
Treatment can beclassified into that of
1. Mild disease (most patients),
2. Moderate to severe active disease,
3. Post inflammatory complications.
4. The first measure taken in all cases should be the
cessation of smoking.
5. Thyroid dysfunction should also be managed
adequately
48.
Treatment (Mild disease)
1.Topical artificial tear drops in the day time and
ointment at bed time are useful for relief of ocular
surface drying
2. Head elevation with three pillows during sleep to
reduce periorbital oedema.
3. Eyelid taping during sleep may alleviate mild
exposure keratopathy.
4. Oral NSAIDs may be used for periocular pain.
49.
Treatment (Optometry pointof view)
1. For diplopia, Fresnel prisms or occlusion therapy
may be considered.
2. Prism for restricted ocular motility
3. Base in prism for reduced convergence
4. Others are lifestyle modifications e.g. sodium
restriction to reduce water retention and tissue
edema
50.
Treatment (Moderate toSevere disease)
1. Guanethidine 5% eyedrops may decrease the lid
retraction caused by overaction of Muller’s muscle.
2. Systemic steroids may be indicated in acutely
inflamed orbit with rapidly progressive chemosis
and proptosis with or without optic neuropathy
3. Radiotherapy (2000 rads given over 10 days period).
It may help in reducing orbital oedema in patients
where steroids are contraindicated
51.
Treatment (Moderate toSevere disease)
5. Lateral tarsorrhaphy
Performed in patients with exposure keratopathy (with
mild to moderate proptosis) not responding to topical
artificial tears
6. Extraocular muscle surgery.
It should be carried out for left-out diplopia in primary
gaze, after the congestive phase of disease is over and
the angle of deviation is constant for the last 6
months.
52.
Treatment (Post complications)
7.Orbital wall decompression
It involves the orbital floor, medial wall, and lateral
wall. In rare cases the roof of the orbit may also be
decompressed surgically.

#19 The most common cause of unilateral or bilateral upper eyelid retraction is Graves’ ophthalmopathy, or thyroid eye disease. Early in Graves’ disease, eyelid malposition may result from increased sympathetic activity. With time, the levator palpebrae superioris and Müller’s muscle become hypertrophic, fibrotic, and adherent to orbital tissues. Patients with thyroid eye disease often have associated globe proptosis and lid lag along with eyelid retraction. Lower lid retraction is usually not seen in patients with Graves’ ophthalmopathy without concomitant retraction of the upper lids. Upper eyelid retraction in thyroid eye disease often has temporal flare, when retraction is more pronounced at the lateral aspect of the eyelid.
