When is Ptosis not “just” Ptosis?
Cat Burkat, MD, FACS Associate Professor
Oculoplastic, Facial Cosmetic, & Orbital Surgery
University of Wisconsin- Madison
March 7, 2015
Typical Ptosis
• Complains of drooping – Heavy lid, fatigue, has to lift lid
manually
• MRD low, approaches pupil • Droopy lid triad:
1. Skin excess 2. Levator muscle dehiscence
(Involutional ptosis) 3. Brow/forehead ptosis

So…we all sag as we age
When can’t we blame it on age?
• 52 yo M with progressive RUL ptosis over 1 year - Hard to put contacts in OD
• Motility, pupils, SLE nl • MRD 0.5 mm OD, 4 mm OS • LVF 11 mm OD, 16 mm OS • Recommend internal ptosis repair
Case

3
• Intraoperative findings: – Eversion – Thick lid
H&E. 40x
H&E. 10x Case
• Diagnosis: RUL ptosis-- yes… but – MRD 0.5 mm OD, 4 mm OS – LVF 11 mm OD, 16 mm OS
• Levator dehiscence alone (which can occur with CL use) should =normal levator function!
Patient:
Ptosis with poor levator function was due to infiltration of levator muscle from lymphoma

• Levator function: – Normal ≥ 15mm – Must negate forehead
movement
• 43 yo M, never seen MD for 30 yrs, with eyelid drooping and “lumps” OU.
Patient: LUL ptosis yes… but also lower lid elevation (or reverse ptosis), eyelid thickening, enophthalmos
- If you don’t ask about the remote history, they often won’t tell
- Ptosis in this pt due to enophthalmos

Metastasis to the Orbit • Accounts for ≈ 10% of all orbital neoplasms. (5% hematogenous,
5% from adjacent structures)
• What is the most common malignancy to spread to orbit? – Breast Cancer (42%) – Lung Carcinoma (11%) – Unknown Primary Cancer (11%) – Prostate (8%) – Melanoma (5%) Average survival after dx is 9 months
• 25% of metastatic tumors to the orbit are the initial presentation
– Metastatic neuroblastoma – Leukemia, lymphoma
• In pediatric population, metastatic disease is far less common
Enophthalmos
• 10% of metastatic cases – 80% breast cancer – Contraction of fibroblasts in the scirrhous tumor →
posterior traction on globe
• Breast > GI > prostate, lung

Case
• 64 yo M with droopy RUL x 3 wks after picked up new glasses. Also complains of intermittent diplopia before then.
• No dysarthria, systemic weakness
• VA: 20/40 OD, 20/20 OS
• Pupils, motility nl. Orthotropic
• MRD minus 2mm OD, +1mm OS
• LVF 12mm OU
• Diagnosis: RUL ptosis-- yes… but – MRD minus 2mm OD, +1mm OS – Acute onset – Intermittent diplopia preceding
• Levator dehiscence alone should = slowly progressive ptosis
Patient: Variable measurements or true fluctuating symptoms should warrant additional evaluation

Ice Pack test • Cheap, safe, quick bedside test • Apply ice to closed lids for 2–5 minutes
– Positive if improvement of diplopia or elevation of MRD by 2 mm – Physiological theory: by cooling skeletal muscle fibers (below 28˚C), the activity of acetylcholinesterases is inhibited
Previous pt: MRD minus 2mm OD, +1mm OS After ice test: MRD +1.5mm OD, +1mm OS
Another Case of MG
• Ice test: – Much over 3 minutes, reduction of muscle fiber temperature below 22˚C may reduce contractile force of the muscle potential false-negative result
• Acetylcholine receptor antibody test
potential false-negative? Patient:
Ptosis due to neuromuscular junction abnormality resulting in decreased muscle contraction

14
Case
• 28 yr old F with ptosis “since she was little” worsening over past yr, resulting in neck pain
– Adopted chin-up position – Severe ptosis BUL – Levator function 4-5mm – Motility nl – No lagophthalmos – Bell’s phenomenon
• Diagnosis: BUL ptosis-- yes… but – Minus MRD – LVF 4-5 mm OU – high arched brows – “small eye openings”
• Ask for family history or photos
Patient:
Ptosis with poor levator function due to hypoplasia of levator muscle (myogenic)

Developmental defects in muscle structure
• Histopathology: levator muscle and aponeurosis are dystrophic, infiltrated or replaced by fat and fibrous tissue – In severe cases,
may be little or no striated muscle
• Higher risk of: – Reoperation – Lagophthalmos
Case • 73 yo M with BUL droopy lids x 25 yrs. Previous lid repair.
– No diplopia, dysarthria – Mild dysphagia – VA, pupils, SLE nl
• Extreme forehead flexion and chin-up position • MRD 0mm OD, minus 2mm OS • LVF 7mm OU • Motility limited in all gazes, except fair in downgaze

CPEO Chronic progressive external ophthalmoplegia
• Slowly progressive paralysis of EOM and eyelid muscles
– Bilateral symmetric severe ptosis followed by ophthalmoparesis later
• Often do not notice diplopia due to symmetric nature
• Mitochondrial myopathy • Rule out Kearns-Sayre syndrome if young pt:
– CPEO – Onset prior to 20 – Pigmentary “salt & pepper” retinopathy – Cardiac conduction defects, seizures, death
• Regular cardiac exams
Case
• 52 yo F with sudden RUL drooping. No trauma. No pain, decreased vision, diplopia. Not presentable for her public job. • PMH unremarkable • VA, SLE, motility nl

Dx: RUL ptosis but…
• Ptosis • Reverse ptosis • Miosis • Other findings: anhidrosis, anisocoria worse in dark
Patient: Ptosis due to Horner’s Syndrome. Don’t forget the exam basics!
Sympathetically-innervated Muller’s muscle and inferior retractors
Case
• 58 yo F with OS drooping, FBS and redness x 2 mos • Hx of multiple nonhealing corneal ulcers • PMH bipolar disorder with psychosis • VA: HM OS • Corneal scar and pannus • Loss of lashes
Definitely not just ptosis!

• Differential Dx: – Conjunctival intraepithelial neoplasia – Sebaceous cell carcinoma – Lymphoproliferative process – Severe follicular conjunctivitis
