Lid retraction
1. SYMPOSIUM ON LID RETRACTION
Presenter- Dr. Tanvi Gupta
Moderator- Dr. Jayanta Kumar Das
2. Abnormally high/ low lid position in primary position of upper/ lower lid respectively that
exposes the superior/ inferior sclera
Upper lid retaction
Lower Lid Retraction
3. Etiopathology
In the Upper Lid, the mechanisms of retraction could be due to:
LEVATOR MUSCLE
Overactivity or contracture (Specially in thyroid ophthalmopathy)
Abberant or increased innervation
Decreased inhibition
MULLER’S MUSCLE
Sympathetic hyperactivity
In the Lower eyelid
Fibrosis of inferior rectus / inferior tarsal muscle -> retracting action to the lower lid via its
capsulopalpebral head.
In the cases of lower eyelid trauma and postsurgical trauma -> intralamellar scarring or anterior
lamellar shortening may vertically shorten the eyelid.
5. I. Inflammatory causes of lid retractions are:
Thyroid eye disease
Orbital Pseudotumour
Cicatricial conjunctival Disease
Thyroid eye diseases are most common cause of lid retraction seen in
clinical practice.
Upper lid
1. Levator muscle contraction – inflammation, fibrosis
2. Levator adhesions to the orbicularis and septum
3. Hyperactivity of the sympathetic nervous system (in hyperthyroidism)- activation of Muller's muscle,
inflammatory fibrosis of Muller’s
Lower eyelid
Fibrosis of the inferior rectus/ inferior tarsal muscle, exerting a retracting action to the lower lid
via its capsulopalpebral head, is the probable mechanism.
6. Common finding in thyroid-related eyelid retraction is lateral flare.
In this condition, the eyelid retraction is more severe laterally than medially, resulting
in an abnormal upper eyelid contour that appears to flare upward along the lateral half
of the eyelid margin.
7. II. Involutional/ Congenital/ Neurogenic
Congenital
typically result from neurological causes.
Primary congenital eyelid retraction is a diagnosis of exclusion.
Lid retraction may be due to a combination of both anterior and posterior lamellar
shortening that results from developmental abnormalities.
May involve the upper, lower, or both eyelids.
Congenital hyperthyroidism, aberrant innervation of the third cranial nerve, Marcus
Gunn (jaw-winking) syndrome, seventh cranial nerve palsy, and orbital tumor must be
ruled out.
8. Aberrant regeneration of Third Nerve
Acquired - Slow growing intra-cavernous aneurysm or meningioma can press upon the 3rd
nerve.
Congenital - Marcus gunn jaw winking phenomenon (commenest form of trigemino oculo
synkinesis)
Midbrain lesion (pretectal syndrome) –lid retraction mostly results from damage to
supranuclear posterior commissure.
Supranuclear lesion (disinhibition of levator muscle)
Nuclear lesion (+/- lid syndrome) - ipsilateral ptosis, contra lateral eyelid retraction
Sympathetic overactivity
Claude Bernard syndrome- cyclic spasm of pupil and lid retraction (associated with facial
hyperhidrosis and headache)
Anxious & psychotic pts
10. III. Mechanical
Prominent globes- high myopes, Buphthalmos, Proptosis, Craniostenosis,
Paget'disease
Cicatricial scarring of lid
Contact Lens wear / lost Contact Lens under eyelid
Neoplastic (eyelid tumour)
Infection- herpes zoster ophthalmicus (severe inflammation) & scleroderma
11. IV. Postoperative
Blepharoplasty overcorrection-lower lid
Overcorrection of Ptosis
Excessive Levator Resection
Eyelid tumour resection & reconstruction of lid
Orbital floor fracture repair -> external subciliary approach- lower lid
Orbicularis myectomy
Retinal detachment surgery with encircling buckles
Excessive vertical superior rectus surgery due to the anatomical connections between the
superior rectus and the levator muscle
Shortening of anterior lamella from excessive skin removal
13. V. Pharmacologic
Sympathetic agents – Phenylephrine, Apraclonidine, Corticosteroids
VI. Traumatic
Eyelid disruption of upper or lower lid with scarring
Lid laceration
Orbital floor fracture-
Inferior Rectus disinsertion
Traumatic lid disruption – lower lid

16. Transient
Normal infants-80% of normal infants (eye popping reflex)
Preterm infants - due to immature myelinisation of extrageniculate visual pathway
Maternal hyperthyroidism
Dorsal mesencephalic lesions (Collier's Lid retraction sign)
Multiple sclerosis (third nerve fascicle involved)
Bilateral episodic lid retraction in petitmal /myoclonic seizures
Oculogyric crisis
17. Voluntary/ non organic finding
Myasthenia gravis
Post tetanic facilitation of levator muscles.
19. Ocular discomfort,
foreign body sensation,
photophobia,
epiphora,
other symptoms of exposure keratopathy- due to decreased excursion and lagophthalmos
Alteration in appearance and disfigurement.
In thyroid-related orbitopathy, upper eyelid retraction present in primary gaze is called
Dalrymple sign.
SYMPTOMS
20. Palpebral fissure and levator function - measured with a millimeter ruler.
Great care should be taken to maintain the ruler perpendicular to the line of gaze, to
ensure that the patient maintains exact primary gaze, and with the examiner sitting at eye
level relative to the patient.
Patients is instructed to relax their eyebrows and eyelids during clinical examination and
measurement procedures.
The amount of eyelid retraction is assessed quantitatively in each eye individually as
fixation is maintained.
Vertical phoria and tropia are coincidentally assessed.
EXAMINATION
23. The presence of proptosis, lid lag, lid edema or ophthalmoplegia with the retraction
should prompt evaluation for thyroid eye disease (TED)
Laboratory testing
Thyroid Profile
Thyroid Stimulating Hormone (TSH)
Free T3
Free T4
Some patients with thyroid ophthalmopathy have no serologic evidence for thyroid
disease
Thyroid autoantibodies may be useful in testing for euthyroid - Grave’s
ophthalmopathy, Hashimoto thyroiditis
anti-TPO antibodies,
anti thyroglobulin(TG) antibodies
Orbital ultrasound or orbital computed tomography may confirm thyroid eye disease.
24. Autoantibodies against various eye muscles membrane antigens are detected in
96% patients of lid retractions, but may be present in 20% of normal patients.
‘64-K Da’ membrane antigens is most specific for eyelid retraction
26. The treatment of lid retraction should be aimed at the underlying etiology.
27. Corneal exposure is the most serious complication of lid retraction.
Prior to correction of lid retraction surgically , the immediate treatment
goal is to protect the cornea.
1. Preservative-free tear supplements,
2. Lubricating ointment or gels
3. Punctal plugs
4. Moist chamber shields
5. Taping the eyelid during sleep
28. Temporarily treat eyelid retraction secondary to thyroid-related orbitopathy, because
of its effect on striated fibers in the levator muscle.
The effects of a single injection can last for 3 to 4 months.
Botulinum A toxin injection can be used to reduce the lid retraction in symptomatic
cases.
30. Retraction can be with-
Shortage of skin
Shortage of Conjunctiva
No shortage of skin or conjunctiva
1. Shortage of skin- Ectropion, retraction of lid-> Skin Graft, Z plasty
2. Cicatricial changes in Conjunctiva- mostly with entropion- lengthening of
posterior lamella
3. No shortage of skin or conjunctiva
Retraction due to shortened lid retractors
(i) Muller’s muscle excision (upto 2 mm)
(ii) Muller’s + Levator aponeurosis recession/ myotomy (upto 3 mm)
(iii) Muller’s + Levator aponeurosis + Spacers (4 mm or more)
31. As a general principle for Upper Lid retractions:
Up to 3 mm eyelid retraction -> a graded Muller's muscle resection.
For larger amounts of lid retraction (3 mm to 4 mm)
Complete extirpation of Muller's muscle
+
stripping or recession of the levator aponeurosis or marginal myotomy of the levator aponeurosis and
Mueller's muscle
+/-
adjustable sutures and interposition of spacers between distal end of levator and tarsus
For Lower Lid retractions
Though, no conclusive approach is present, the lower eyelid retractors may be approached through an
infraciliary incision or conjunctival approach.
Less than 2mm of retractions, -> recession of Lower Lid retractors
For larger retractions (>2mm) -> Lower Lid retractor lengthening
Retraction due to shortened lid retractors
32. This may be combined with implantation of spacers like
1. Ear cartilage graft
2. Tarsal conjunctival grafts
3. Hard palate grafts
4. Autologous and banked fascia lata
5. Donor sclera- Preserved sclera has been reported as a spacer in the recession of the
levator aponeurosis, with minimal complications.
6. Processed collagen
7. Gortex
8. AlloDerm grafts (alloplastic material)
between the tarsus and capsulopalpebral fascia with superior placement of the lateral
canthal tendon
The purpose of the anterior superior placement of the lateral canthal tendon is to
counteract the lower lid retraction and proptosis.
34. Dysthyroid lid retraction
Classically divided into five groups, each of which is performed through an external or conjunctival approach:
1. Excision of Muller's muscle
2. Levator aponeurosis weakening or recession
3. Excision of Muller's muscle combined with levator aponeurosis weakening or recession
4. Marginal myotomy of the levator aponeurosis
5. Use of spacers such as tarsus, sclera, hard palate, ear cartilage, or AlloDerm (LifeCell,
Branchburg, NJ), dermal fat graft, skin graft, SOOF (Subocularis ocular fat).
35. For retractions with other etiologies, the general surgical principles followed are:
In traumatic scarring -> excision of scar, and closure of healthy tissue
Tissue transfer - Z plasty or VY plasty
36.
37. In ant lamellar shortening- > release the scar and place full thickness skin graft
For facial nerve palsy - Mullers muscle excision and lateral tarsorrhaphy
In greater degree of Lid Retraction- lid loading with gold weight, palpebral spring,
temporalis muscle transfer, or levator recession.
A graded recession of Levator-Muller muscle complex, more temporal & central than nasal;
leaving the orbital septum intact, severing all the fibrotic bands between Muller’s muscle
and conjunctiva- gives satisfactory outcome.

PROPTOSIS
These include inflammatory fibrosis of Müller’s muscle, abnormal sympathetic
tone in Müller’s muscle, proptosis, contracture of the inferior rectus muscle with superior rectus hyperactivity (fixation duress), and overmedication
with thyroid replacement
With inferior rectus restriction (thyroid, trauma), any effort to maintain vertical eye alignment results in overaction of the superior rectus muscle, and because the levator muscle is linked to the superior rectus muscle action, increased innervation of the levator muscle will also occur secondarily.
If upper eyelid retraction increases on attempted upgaze and resolves on downgaze, tight inferior rectus muscles are probably contributing to the upper eyelid retraction and should be surgically recessed first, before surgical correction of the eyelid retraction is entertained.
Unmasking Pseudoretraction- Hering’s test
Manual elevation of ptotic eye- > measurement of MRD
this permits the patient to continue fixation with the eye but removes the need for excessive innervation to both eyelids in an attempt to reduce the ptosis. As a result, the contralateral lid returns to its normal position after several seconds. Once the manually elevated lid is then released, the afferent input is once again increased to both eyelids and results in an increase in the lid position of the contralateral eye.
Lagophthalmos- inability to close eyelids completely
abnormally high upper eyelid in downgaze is called the von Graefe sign or lid lag
