evaluation of ptosis
• head posture,Eyebrow position, eyelid masses, inflammation, proptosis
• pupillary size, reaction, heterochromia
• Best corrected Visual Acuity: In infants, make sure infant can fix and follow light with each eye
• Cycloplegic Refraction
evaluation of ptosis• Strabismus Evaluation• Extraocular Muscles Motility: Note

In children
• Presence or absence of Lid fold • Head tilt• Iliff test
Measurements
• Vertical fissure height• Margin reflex distance• LPS action• Lid crease level• Lid level on down gaze
Vertical fissure height
• The distance between the upper and lower eyelid in vertical alignment with the center of the pupil in primary gaze, with the patient’s brow relaxed.
• Normal – 9-10mm in primary gaze• Should be seen in up gaze, down gaze and
primary gaze• Amount of ptosis = difference in palpebral
apertures in unilateral ptosis or Difference from normal in bilateral ptosis
Grading of severity of ptosis
< or = 2mm : mild ptosis= 3 mm : moderate ptosis= or > 4 mm : severe ptosis
MRD• Margin-to-reflex distance 1 (MRD1) : is the
distance from the central pupillary light reflex to the upper eyelid margin with the eye in primary gaze.
• A measurement of 4 - 5 mm is considered normal.
• If the margin is above the light reflex the MRD 1 is a +ve value.
• If the lid margin is below the corneal reflex in cases of very severe ptosis the MRD 1 would be a –ve value.
MRD
• Margin-to-reflex distance 2 (MRD2) : is the distance from the central pupillary light reflex to the lower eyelid margin with the eye in primary gaze. .
• The MRD1 plus the MRD2 should equal the palpebral fissure measurement
Levetor function
• is the distance the eyelid travel from downgaze to upgaze while the frontalis muscle is held inactive at the brow.
• The normal levator function is between 13-17mm
• Lid excursion is a measure of the levator function. The frontalis action is blocked by keeping the thumb tightly over the upper brow and asking the patient to look up from down gaze and measuring the amount of upper lid excursion at the center of the lid.
Berkes method
Grading of levator action
< 4mm – poor levator function5-7 mm – fair levator function8-12 mm – good levtor function
Lid crease
• Position is the distance from the crease to lid margin
• Normal – 8 to 10mm in primary gaze• An absent lid crease is often accompanied
by poor levator function. • If a lid crease is present but is higher than
normal and if a deeper upper lid sulcus is found on that side, note these as signs of a levator aponeurosis disinsertion.
Phenyl ephrine test
• Patients with minimal ptosis (2 mm or less) should have a phenylephrine test performed in the involved eye or eyes
• Either 2.5 or 10% phenylephrine is instilled in the affected eye or eyes. Usually two drops are placed and the patient is reexamined 5 minutes later.
• The MRD1 is rechecked in the affected and unaffected eyes .
• A rise in the MRDl of 1.5 mm or greater is considered a positive test. This indicates that Müller's muscle is viable
Ice test
Investigation
• Serum acetylcholine receptor assay• Tensilon test• EMG• ECG• ERG• T3, T4, TSH
Surgical management
• Wait till 3-4 years of age• Pupil covered operate immeditely

Surgical management
Case 1
• A 25 year old man is seen in OPD 2 months after blunt trauma to right orbit. Examination is normal except for blepharoptosis in RE. Levator function is normal on bothsides and the patient states the eyelid positions were equal on both sides prior to injury. There is no enophthalmous, and the patient does not complain of diplopia.
Case 1
• CT scan to rule out orbital fracture• Tensilon test to rule out myasthenia• Surgical exploration and repair of
aponeurosis• Close observation

Case 2
• Levator aponeurosis advancement• Blepharoplasty• Frontalis suspention• Levator muscle resection
Case 3
• A 10 year old girl has bulging and blepharoptosis of both upper eyelids and recurrent episodes of eyelid inflammation and swelling. The diagnosis is
• Dermatochalasis• Blepharochalasis • Steatoblepharon• blepharospasm
