Blepharoptosis, often shortened to ptosis, means the upper eyelid hangs lower than normal. In plain terms: the top eyelid droops and may cover part of the pupil. This can block the top part of vision, make the eyes look uneven, or make a person tilt their head back to see better. Ptosis can be present at birth (congenital) or appear later (acquired). It can affect one eye (unilateral) or both eyes (bilateral). The droop can be constant or come and go during the day.
Normal eyelid height depends on several parts working together:
The levator palpebrae superioris muscle (the main lifting muscle), controlled by the oculomotor nerve (cranial nerve III).
The Müller’s muscle (a small helper muscle), controlled by the sympathetic nervous system.
The eyelid skin and connective tissues that hold the muscle tendon (called the levator aponeurosis) to the tarsal plate (the firm part of the lid).
The brow and forehead muscles (especially the frontalis, cranial nerve VII) that can “help” lift the lid when it droops.
Ptosis happens when any of these parts is weak, stretched, disconnected, blocked, or poorly controlled by the nerves. Sometimes the eyelid is not truly weak but looks low because the eyeball sits deeper in the socket (enophthalmos) or because extra skin or swelling weighs the lid down (pseudoptosis). Understanding which part failed is the key to treatment.
Ptosis is not only a cosmetic issue. It may:
Reduce the upper visual field, making reading, driving, walking upstairs, and sports harder.
Cause neck strain due to chin-up head posture.
Signal serious nerve problems, such as a third nerve palsy or Horner syndrome.
Affect children’s visual development, leading to lazy eye (amblyopia) or astigmatism if the pupil is covered.
Because ptosis has many possible causes—from simple age-related tendon stretching to urgent neurologic disease—a careful exam is essential.
Types of Blepharoptosis
Aponeurotic (involutional) ptosis
This is the most common type in adults. The levator tendon (aponeurosis) becomes stretched, thinned, or partially detached from the tarsus, usually with age, repeated eyelid rubbing, or long-term contact lens use. The levator muscle is healthy, but its “tendon” no longer transmits full lifting power. The eyelid crease is often high and well-defined, and the lid droop can be worse when tired.Neurogenic ptosis
Here the nerves that control lid lifting are affected. The main patterns are:Cranial nerve III (oculomotor) palsy: levator weakness plus eye movement problems; may be due to diabetes, stroke, aneurysm, or head injury.
Horner syndrome: mild ptosis from Müller’s muscle weakness, small pupil (miosis), and subtle lower-lid changes; due to interruption of the sympathetic nerve pathway.
Aberrant regeneration or miswiring after nerve injury can also cause odd lid movements.
Myogenic ptosis
The muscle itself is weak. Typical examples are myasthenia gravis, chronic progressive external ophthalmoplegia (CPEO), oculopharyngeal muscular dystrophy (OPMD), and other muscular dystrophies. The droop may be variable, may worsen with fatigue, and may be bilateral.Mechanical ptosis
The eyelid is heavy or blocked from lifting. Causes include dermatochalasis (extra skin), large chalazia or tumors, scarring, swelling, or anything that adds weight or stiffness to the lid.Traumatic ptosis
Injury can tear the levator, damage the aponeurosis, or injure the nerves. Surgery, blunt trauma, or lacerations around the upper lid are common triggers.Pseudoptosis
The lid appears low, but the true cause isn’t the lifting mechanism. Examples: enophthalmos (the eye sits deeper in the orbit), prosthetic eye, brow ptosis (sagging eyebrow), or contralateral eyelid retraction making the other side seem lower by comparison.Congenital ptosis
Present at birth. Usually due to poor development of the levator muscle (levator dysgenesis). Children often use the chin-up posture and lift their brow to compensate. This must be monitored carefully to protect vision.
Common Causes of Blepharoptosis
Age-related levator aponeurosis dehiscence
With age, the levator tendon stretches or partially detaches. The muscle is fine, but the “rope” connecting it to the lid is loose, so the lid sags.Long-term hard contact lens wear
Repeated insertion and removal can pull on the levator aponeurosis, speeding tendon stretching and ptosis.Chronic eyelid rubbing or allergies
Frequent rubbing and swelling can stress the tendon and thin the tissues, leading to a slow, acquired droop.Cranial nerve III palsy (oculomotor nerve)
Damage from diabetes, microvascular ischemia, stroke, tumor, aneurysm, or head trauma weakens the levator and eye muscles. This can be urgent if pupil involvement suggests aneurysm.Horner syndrome
Disruption of sympathetic nerves (in the neck, chest, or brainstem) weakens Müller’s muscle, causing mild ptosis with a small pupil and sometimes decreased facial sweating.Myasthenia gravis (MG)
An autoimmune disorder that blocks the neuromuscular junction, causing fluctuating ptosis and double vision, often worse at day’s end and better after rest or cold.Chronic progressive external ophthalmoplegia (CPEO)
A mitochondrial muscle disease causing slowly progressive ptosis and limited eye movements over years.Oculopharyngeal muscular dystrophy (OPMD)
A genetic disorder, usually adult-onset, causing ptosis and swallowing difficulties due to muscle weakness.Congenital levator dysgenesis
The levator muscle is underdeveloped at birth, giving a stiff, poorly functioning eyelid with a low or absent crease.Trauma (blunt or sharp) to the eyelid
Direct injury can tear the levator or aponeurosis, or cause scarring that mechanically restricts lift.Post-surgical changes
Eyelid or orbital surgery, even some non-lid surgeries, can unintentionally weaken or disinsert the levator.Eyelid tumors or large chalazia
A mass adds weight or distorts tissue planes, making lift harder (mechanical ptosis).Dermatochalasis (excess eyelid skin)
Heavy extra skin weighs the lid down, especially in older adults.Eyelid edema (swelling) or inflammation
Allergies, thyroid eye disease, infection, or fluid retention add weight and stiffness to the lid.Cicatricial changes (scarring)
Scars shorten or tether the eyelid so it cannot glide upward normally.Botulinum toxin diffusion
Cosmetic forehead or crow’s-feet injections can sometimes spread to the levator region, causing a temporary ptosis.Enophthalmos or orbital fat atrophy
When the globe sits deeper or the orbit loses volume, the lid may appear lower (pseudoptosis).Phthisis bulbi or prosthetic eye
A shrunken globe or prosthesis changes lid support, causing apparent ptosis.Diabetes-related neuropathy
Diabetes can injure the oculomotor nerve (microvascular palsy), leading to ptosis that often improves over months.Stroke, tumor, aneurysm, or cavernous sinus disease
Central or skull-base problems can disrupt nerve pathways to the lid elevators; these require urgent evaluation if suspected.
Typical Symptoms and Functional Complaints
Droopy upper eyelid
The most obvious sign—one lid sits lower, sometimes covering the pupil.Reduced upper (superior) visual field
Objects above eye level are harder to see; people often lift their chin or eyebrows to compensate.Eye fatigue and heaviness
The droopy lid feels heavy, especially later in the day.Headache or brow ache
Constant frontalis muscle overuse to lift the brow can cause discomfort or headache.Neck or back strain from chin-up posture
To see under the droopy lid, people may tilt the head back, leading to soreness.Uneven eyelids in photos or mirror
Asymmetry is especially noticeable in pictures or at the end of the day.Variable droop (worse with fatigue, better after rest)
Strong clue for myasthenia gravis.Double vision (diplopia)
If nerves or eye muscles are involved (e.g., CN III palsy), eye alignment problems can cause double vision.Eye strain while reading
Compensating for blocked upper vision can make near work tiring.Tearing or watery eye
Reflex tearing can occur due to surface irritation or abnormal blink patterns.Dryness or grittiness
Irregular blink and lid position can disturb the tear film.Frequent forehead wrinkling
Brow lifting becomes a habit to raise the eyelid a little higher.Narrowed eye opening (palpebral fissure)
The vertical opening from upper to lower lid is smaller.Difficulty driving, climbing stairs, or sports
Losing the upper field makes these tasks harder or unsafe.Child holds things close or tilts head
In congenital ptosis, children may raise chin or use brow lift to keep the pupil clear.
Diagnostic Tests
Below are the most useful tests, grouped by category. Each one helps answer a key question: Is the problem muscle, nerve, tendon, weight, or “look-alike” (pseudo)? We also want to catch urgent causes (like aneurysm-related CN III palsy) and vision-threatening issues in children.
A) Physical Exam
General inspection of eyelid height and symmetry
The examiner compares the resting lid position in both eyes, checks if the lid covers the pupil, and notes asymmetry. They also observe if the droop changes with fatigue or improves after rest, which hints at myasthenia gravis.Pupil exam (anisocoria) and light reactions
Unequal pupils with mild ptosis suggests Horner syndrome (small pupil on the ptotic side), while a large, poorly reactive pupil with ptosis may suggest a compressive CN III palsy. This distinction helps guide urgency and imaging.Extraocular movement testing
The doctor checks how the eyes move in all directions. Abnormal movements plus ptosis point toward nerve or muscle disease (e.g., CN III palsy or CPEO), rather than a simple tendon problem.Brow and forehead assessment (frontalis overaction)
Prominent forehead wrinkling and raised eyebrows indicate the patient is compensating for a droopy lid using the frontalis muscle. This is common in aponeurotic ptosis.Eyelid skin, crease, and lash position
A high lid crease with a thin upper lid often means aponeurotic ptosis; absent/low crease suggests congenital levator dysgenesis. Skin excess (dermatochalasis), edema, or masses suggest mechanical ptosis.
B) Manual (Bedside) Tests
MRD1 (Margin–Reflex Distance 1) measurement
MRD1 is the distance from the corneal light reflex to the upper lid margin in primary gaze. Normal is ~4–5 mm. A smaller MRD1 means more ptosis. It’s a simple ruler-based measure that quantifies severity.Palpebral fissure height
This is the vertical opening between upper and lower lids. Measuring it in straight gaze and in upgaze/downgaze helps show levator strength and whether the droop worsens with fatigue.Levator function (excursion) test
The brow is gently stabilized (to stop the frontalis from helping). The patient looks down then up while the examiner measures how many millimeters the upper lid travels. Good levator function suggests aponeurotic (tendon) ptosis; poor function points to myogenic or congenital causes.Fatigue (sustained upgaze) test
The patient looks up for 30–60 seconds. If the lid drops more during the effort, it suggests myasthenia gravis or fatigable muscle. Short rest may partially improve it.Cogan’s lid twitch sign
In myasthenia gravis, when the patient looks down then quickly to straight ahead, the upper lid may overshoot upward briefly, then falls. This twitch supports neuromuscular junction problems.Pharmacologic eyelid drop tests (phenylephrine or apraclonidine)
Phenylephrine 2.5% on the ptotic eye can temporarily lift the lid if Müller’s muscle is responsive. This predicts success for Müller’s Muscle–Conjunctival Resection (MMCR) surgery.
Apraclonidine can reverse the small-pupil and mild ptosis of Horner syndrome by stimulating alpha receptors, helping confirm the diagnosis.
These are quick in-office tests that point to sympathetic pathway or Müller’s muscle involvement.
C) Lab / Pathological Tests
Acetylcholine receptor (AChR) antibody test
A blood test looking for antibodies that block neuromuscular transmission in myasthenia gravis. A positive test supports MG, though some patients (especially with only eye symptoms) can be antibody-negative.MuSK (± LRP4) antibody test
If AChR antibodies are negative, testing MuSK (and sometimes LRP4) can find other autoimmune targets in MG. This helps confirm the diagnosis and guide treatment.Thyroid function tests (TSH, free T4 ± T3)
Thyroid disease, especially thyroid eye disease, can alter eyelid position and cause swelling or retraction that mimics ptosis. Checking thyroid hormones helps find or rule out this contributor.Glucose/HbA1c for diabetes screening
Diabetes can cause microvascular nerve palsies (including CN III), leading to ptosis. Finding elevated glucose or HbA1c supports a diabetic cause for a nerve droop.
D) Electrodiagnostic Tests
Repetitive nerve stimulation (RNS)
Nerve stimulation is repeated while measuring the muscle’s electrical response. A decremental response is supportive of myasthenia gravis, though it is less sensitive for purely eye symptoms.Single-fiber electromyography (SFEMG)
This is the most sensitive test for neuromuscular junction transmission problems. It looks for jitter (inconsistent activation) in tiny muscle fibers, supporting a diagnosis like MG when routine tests are unclear.
E) Imaging Tests
MRI of brain and orbits with contrast
MRI checks the brainstem, cranial nerves, cavernous sinus, orbit, and eyelid tissues. It can reveal nerve inflammation or compression, muscle disease, apical/orbital masses, and other causes that explain ptosis.MRA/CTA of head and neck
If a compressive CN III palsy is suspected—especially with a dilated or poorly reactive pupil—vascular imaging looks for an aneurysm or other vascular problems that may need urgent treatment.CT orbit and sinuses
CT shows bone and acute trauma well. It helps in fractures, foreign bodies, sinus disease, or when masses or calcifications are suspected to be weighing the lid down.Orbital/eyelid ultrasound
A quick way to see superficial masses, cysts, chalazia, or orbital lesions contributing to mechanical ptosis, especially when MRI/CT is not immediately needed.
Non-pharmacological Treatments (Therapies & Other Measures)
Below are practical, evidence-informed options you can discuss with your eye doctor. For each item, you’ll see Description, Purpose, and Mechanism (how it helps). None of these replace medical care if you have red-flag symptoms (see “When to see a doctor”).

Side effects: Serious infection risk (e.g., meningococcal with C5 inhibitors)—vaccination required; specialist management only.
Note: Most drops (oxymetazoline/apraclonidine/phenylephrine) only give temporary lift. Definitive correction of structural ptosis is usually surgical.
Dietary & Supportive Supplements
There is no supplement that can “fix” ptosis. These options may support nerve, muscle, skin, and ocular surface health. Discuss with your clinician, especially if pregnant, on blood thinners, or with kidney/liver disease.
Vitamin B12 (methylcobalamin) — 1000 mcg/day oral
Supports nerve myelination and neuromuscular function; correct deficiency that can worsen fatigue.Vitamin D3 — 1000–2000 IU/day (or per level)
Immune modulation and muscle strength support; correct low levels.Omega-3 (EPA/DHA) — 1 g/day
Anti-inflammatory; may improve meibomian gland function and tear film (comfort).Coenzyme Q10 — 100–200 mg/day
Mitochondrial energy support; may help muscle endurance.Magnesium (citrate/glycinate) — 200–400 mg/day
Neuromuscular stability; avoid excess if kidney disease.Acetyl-L-carnitine — 500–1000 mg twice daily
Mitochondrial fatty-acid transport; nerve support.Alpha-lipoic acid — 300–600 mg/day
Antioxidant; commonly used in neuropathy support.Folate (L-methylfolate) — 400–800 mcg/day
DNA synthesis; correct deficiency that impairs tissue repair.Vitamin B1 (thiamine) — 50–100 mg/day
Nerve conduction support.Vitamin C — 250–500 mg/day
Collagen synthesis and antioxidant defense for skin/soft tissues.Zinc — 10–15 mg/day

Retinal/neuromuscular support; generally well tolerated.Lutein + Zeaxanthin — 10 mg + 2 mg/day
General macular/ocular surface antioxidant support (cosupportive, not ptosis-specific).
Regenerative / Stem-Cell–Type” Therapies
Important: There are no approved stem-cell or regenerative drugs that directly “repair” a stretched levator tendon or instantly correct ptosis. The options below are advanced immunotherapies used for generalized myasthenia gravis (gMG) or severe autoimmune disease when MG is the cause of ptosis. They require specialist oversight.
Eculizumab (C5 inhibitor)
Dose: 900 mg weekly ×4, then 1200 mg every 2 weeks.
Mechanism: Blocks terminal complement; reduces AChR damage.
Note: Meningococcal vaccination required; infection risk.Ravulizumab (long-acting C5 inhibitor)
Dose: Weight-based loading, then every 8 weeks.
Mechanism: Same pathway as eculizumab, longer interval.
Note: Same vaccination/infection precautions.Efgartigimod alfa (IV) / Efgartigimod hytrulo (SC)
Dose: Weight-based weekly for 4 weeks, then cycles as needed.
Mechanism: FcRn blockade lowers pathogenic IgG.
Note: Monitor for infections; individualized scheduling.Rozanolixizumab-noli (SC)
Dose: Weekly SC injections for defined cycles (weight-based).
Mechanism: FcRn blockade lowering IgG.
Note: Headache, nausea possible; infection risk.Rituximab (anti-CD20)
Dose: Commonly 375 mg/m² weekly ×4 or alternative regimens.
Mechanism: B-cell depletion reduces autoantibody production.
Note: Screen for hepatitis B; infusion reactions.Autologous hematopoietic stem-cell transplant (HSCT) (rare, experimental for refractory autoimmunity)
Mechanism: Resets immune system after ablative therapy.
Note: Significant risks; not a standard ptosis treatment—reserved for select, life-impacting autoimmune disease under trials/specialists.
Surgeries
Surgery is the definitive fix for structural ptosis. The choice depends on levator function and severity.
External levator advancement/resection
Procedure: Through a skin incision in the lid crease, the surgeon tightens or advances the levator aponeurosis and sets lid height/symmetry.
Why it’s done: Most common for aponeurotic ptosis (age, contact lenses).
Mechanism: Restores the tendon connection to lift the lid.Müller muscle–conjunctival resection (MMCR / “posterior approach”)
Procedure: From the inside of the eyelid, a measured strip of conjunctiva + Müller’s muscle is removed; no skin incision.
Why: Good cosmetic recovery and predictable lift when the phenylephrine test is positive.
Mechanism: Shortens/activates Müller’s muscle to elevate the lid a few millimeters.Fasanella–Servat (limited posterior resection)
Procedure: Small resection of tarsus + conjunctiva + Müller’s in mild ptosis.
Why: Quick procedure for selected cases with mild droop.
Mechanism: Shortens posterior lamella → modest lift.Frontalis sling (suspension)
Procedure: Silicone or fascia sling connects the lid to the forehead (frontalis) muscle.
Why: For very poor levator function (e.g., severe congenital ptosis).
Mechanism: The forehead muscle becomes the lifter—patient raises brow to lift lid.Combined ptosis repair with blepharoplasty/brow lift
Procedure: Corrects true ptosis plus excess skin and/or low brow in the same sitting.
Why: Many adults have mixed problems; combined surgery optimizes vision and appearance.
Mechanism: Structural tightening + skin/fat sculpting + brow elevation.
Risks across surgeries: Over/undercorrection, asymmetry, dry eye, contour change, bleeding, infection, need for revision. Outcomes are usually excellent with proper selection.
Prevention Tips
While not all ptosis is preventable, these habits help protect your eyelids and reduce worsening:
Avoid vigorous eye rubbing.
Manage allergies early to limit lid swelling.
Use contact lenses wisely: proper fit; limit overwear; consider daily disposables.
Tell injectors about ptosis before any cosmetic Botox.
Practice gentle makeup/cleanser routines—no harsh scrubbing.
Wear eye protection to prevent trauma.
Stop smoking and avoid secondhand smoke.
Sleep with slight head elevation to reduce morning swelling.
Control systemic illnesses (diabetes, thyroid, autoimmune disease).
Seek assessment early if you notice new droop, double vision, or unequal pupils.
When to See a Doctor Urgently
Sudden ptosis with severe headache, eye pain, double vision, or unequal pupils (possible nerve problem or aneurysm).
Ptosis in a child (risk of amblyopia).
Droop that fluctuates through the day with fatigue or chewing trouble (possible myasthenia gravis).
After head/eye trauma.
With new neurologic symptoms (weakness, numbness, facial asymmetry).
If eyelid blocks the pupil and affects driving/reading.
What to Eat and What to Avoid
What to eat (supportive patterns):
Protein-rich foods (fish, eggs, legumes, lean meats) to support muscle repair.
Leafy greens & colorful vegetables (spinach, kale, bell peppers) for vitamins A/C and antioxidants.
Omega-3 sources (fatty fish, flax, walnuts) for anti-inflammatory support.
B-vitamin sources (eggs, dairy, fortified cereals) to support nerves; include B12 if you’re vegetarian/vegan.
Citrus and berries for vitamin C and collagen support.
Hydration: water or unsweetened tea for tear film comfort.
What to limit/avoid:
Excess salt (can worsen eyelid puffiness).
Excess alcohol (dehydration, swelling next day).
Highly processed, high-sugar foods (systemic inflammation).
Irritating cosmetics or adhesives if you have sensitive lids.
Unverified “miracle” eye drops or supplements sold online—risk of harm.
Frequently Asked Questions
Can ptosis go away on its own?
If droop is from fatigue or temporary swelling, it can improve. Structural ptosis usually needs surgery for a lasting fix.Are there exercises to lift the eyelid?
No exercise reliably fixes true ptosis. Gentle care may help comfort but won’t tighten a stretched tendon.Will Upneeq® (oxymetazoline) cure my ptosis?
It temporarily lifts the lid (hours). It doesn’t repair the tendon; effect wears off daily.Do eye creams help?
Creams may improve skin texture but cannot lift a weak or stretched lid.Is surgery safe?
When performed by an oculoplastic surgeon, ptosis surgery is commonly safe and effective. As with any surgery, there are risks and a small chance of revision.How do doctors decide which surgery I need?
They test levator function, lid height, response to phenylephrine, brow position, and skin excess, then choose levator advancement, MMCR, sling, or a combination.Can Botox cause ptosis?
Yes—if the toxin spreads to the levator. It’s usually temporary (weeks). Experienced injectors reduce this risk.Is ptosis the same as dermatochalasis (extra skin)?
No. Dermatochalasis is “heavy skin.” Ptosis is a low lid margin. You can have both.Will insurance cover ptosis surgery?
If the lid blocks vision and testing shows visual improvement with lifting, insurers often cover it. Purely cosmetic cases may not be covered.How long is recovery after surgery?
Most people return to light activity in a few days; bruising/swelling improve over 2–3 weeks; full settling 6–12 weeks.What if only one eye is droopy?
The surgeon may adjust both lids for symmetry; the brain’s adaptation can make the other eye look different after a unilateral repair.Can children outgrow ptosis?
Congenital ptosis doesn’t usually go away. Early treatment prevents amblyopia and abnormal head posture.What tests might I need?
A complete eye exam; sometimes ice test or edrophonium history for MG, apraclonidine test for Horner’s, and imaging if a nerve problem is suspected.Are “stem cells” available to fix ptosis?
No approved stem-cell treatment directly corrects ptosis. Be cautious about marketing claims.Can lifestyle changes help?
Yes—for comfort and appearance (sleep, hydration, allergy control, contact lens habits), but structural ptosis still needs surgery for a lasting lift.
