Vertical gaze palsy means a person cannot move both eyes normally up or down on command. The problem is not in the eyeball muscles themselves—it is usually in the brain’s control centers that coordinate vertical eye movements, mainly in the upper midbrain (the rostral interstitial nucleus of the medial longitudinal fasciculus, interstitial nucleus of Cajal, and the posterior commissure). When these tiny centers are damaged—by stroke, bleeding, tumor, inflammation, infection, degeneration (like progressive supranuclear palsy, PSP), hydrocephalus, or head injury—the brain cannot correctly send signals to the eye muscles. People may notice trouble looking up (common), looking down, or both; double vision; abnormal head posture (tilting the chin up or down to compensate); difficulty reading stairs or pouring liquids; and sometimes light-near dissociation of pupils. Because VGP reflects where the damage is rather than one single disease, treatment focuses on the underlying cause, plus safety, rehab, and visual aids.

Vertical gaze palsy means a person cannot move the eyes up, down, or both as freely as normal. The word “vertical” means up and down. The word “gaze” means where your eyes are pointing. The word “palsy” means weakness or loss of movement.

So, vertical gaze palsy is a problem where the eyes cannot look up or look down properly, even though the eyes, eye muscles, and vision may otherwise be healthy. This problem often comes from wiring issues in the brain (especially a small area in the upper brainstem called the midbrain) that normally tells the eye muscles when and how to move.

People with vertical gaze palsy may say:

• “I can’t look up without lifting my chin,” or

• “I miss steps when going down the stairs,” or

• “My eyes feel stuck when I try to look down at a book.”

Some people also have other eye signs, like eyelid pulling up, pupil reaction changes, or jerky eye movements that happen when they try to look up.

How normal vertical eye movement works

To move the eyes up or down, your brain uses a tiny control center in the midbrain:

• The rostral interstitial nucleus of the medial longitudinal fasciculus (riMLF) helps make quick jumps of the eyes called saccades (like when you look from one line of text to the next).

• The interstitial nucleus of Cajal (INC) helps hold the eyes steady after they move.

• The posterior commissure is a crossing bridge that lets signals travel between the two sides of the brain for coordinated up-and-down movement.

• These brain centers send signals down cables called the medial longitudinal fasciculus (MLF) to the eye movement nerves:

  • Oculomotor nerve (III) for upgaze muscles (superior rectus, inferior oblique) and some downgaze control (inferior rectus),

  • Trochlear nerve (IV) for the superior oblique muscle (helps with downward and inward movement).

If these control centers, bridges, or nerve pathways are damaged, the eyes cannot look up or look down normally. This is often called a “supranuclear” problem, meaning the control signal before it reaches the eye movement nerve cells is disrupted.

Types of Vertical Gaze Palsy (with simple explanations)

1. Upgaze palsy (cannot look up well)
   Eyes cannot look up. People lift their chin to see above. Reading signs overhead or reaching high shelves becomes hard.

2. Downgaze palsy (cannot look down well)
   Eyes cannot look down. People drop their chin or tilt the head down to see a phone or book. Going downstairs is risky because looking down at steps is difficult.

3. Complete vertical gaze palsy (both up and down limited)
   Both up and down movements are poor. People rely on moving their head and neck more.

4. Supranuclear vertical gaze palsy
   The problem is in the brain control centers (above the eye nerves). Reflexes that bypass these centers (like the vestibulo-ocular reflex, where the eyes move when the head is quickly turned) may still move the eyes up or down. This helps doctors tell where the problem is.

5. Nuclear vertical gaze palsy
   The problem is in the eye movement nerve nuclei (the actual “eye nerve centers” in the midbrain). Both voluntary and reflex movements may be limited.

6. Infranuclear vertical gaze limitation (a mimic)
   The problem is below the nerve centers, such as eye muscles, eye muscle tendons, or mechanical blocks in the orbit (eye socket). It can look like vertical gaze palsy but is not from the brain control centers.

7. Progressive vertical saccade slowing
   Early stage where quick eye jumps upward or downward become slow before movement is fully lost. Often seen in neurodegenerative diseases (for example progressive supranuclear palsy).

8. Intermittent / fatigable vertical gaze weakness (a mimic)
   Vertical movement may be normal at first but worsens with fatigue and improves with rest or ice (typical of myasthenia gravis). This is not a brain control issue, but it mimics it.

9. Congenital vertical gaze palsy
   Present from birth, due to developmental wiring issues or congenital eye muscle disorders.

10. Dorsal midbrain (Parinaud) syndrome
    A classic upgaze palsy pattern often with eyelid retraction, pupil light-near dissociation (pupil reacts better when focusing near than to light), and convergence-retraction nystagmus (eye jerks backward when trying to look up). Often from pressure on the back of the midbrain.

By pattern and cause

1. Upgaze palsy – difficulty or inability to look upward; classic in dorsal midbrain (Parinaud) syndrome.

2. Downgaze palsy – difficulty looking downward; can cause tripping on stairs and reading problems; seen in PSP or ventral midbrain lesions.

3. Combined up- and down-gaze palsy – severe vertical movement loss in both directions.

4. Supranuclear vertical gaze palsy – command-driven eye movement is impaired, but reflex movements (like the doll’s head maneuver/oculocephalic reflex) may be partly preserved because the final motor pathways and muscles still work.

5. Nuclear/internuclear vertical gaze palsy – direct injury to nuclei or connecting fibers (riMLF/INC/MLF), often more complete loss and poorer reflex sparing.

6. Parinaud (dorsal midbrain) syndrome – upgaze palsy with convergence-retraction nystagmus, light-near dissociation, eyelid retraction (Collier sign); often from pineal mass or hydrocephalus.

7. Degenerative vertical gaze palsy – progressive, typically in PSP (early downgaze difficulty).

8. Vascular vertical gaze palsy – due to ischemic or hemorrhagic stroke of the midbrain/thalamus.

9. Tumor-related vertical gaze palsy – pineal tumors, metastases, gliomas compressing dorsal midbrain.

10. Hydrocephalus-related vertical gaze palsy – enlarged third ventricle stretching the dorsal midbrain.

11. Traumatic vertical gaze palsy – midbrain contusion, shearing, or hemorrhage after head injury.

12. Inflammatory/autoimmune vertical gaze palsy – multiple sclerosis, neurosarcoidosis, autoimmune encephalitis.

13. Infectious vertical gaze palsy – tuberculosis, toxoplasmosis, viral encephalitis affecting midbrain.

14. Metabolic/toxic vertical gaze palsy – Wernicke encephalopathy, drug toxicity (rarely), osmotic demyelination.

15. Congenital vertical gaze limitation – rare developmental pathway issues.

16. Psychogenic/functional mimic – apparent limitation without structural damage (diagnosis of exclusion).

17. Ophthalmoplegia mimics – severe myasthenia gravis or restrictive myopathy can mimic but are not true supranuclear palsies.

18. Intermittent vertical gaze disturbance – fluctuates with raised intracranial pressure or metabolic state.

19. Partial vertical saccade palsy – fast eye jumps (saccades) impaired vertically; smooth pursuit partly spared.

20. Vertical pursuit palsy – smooth tracking vertically impaired more than saccades (suggests specific pathway involvement).

 Causes of Vertical Gaze Palsy

1. Dorsal midbrain (Parinaud) syndrome
   Damage or pressure on the back of the midbrain blocks upgaze signals. Often comes with special eye signs (described above).

2. Pineal region tumor (e.g., germinoma)
   A tumor near the pineal gland sits just behind the midbrain and can press on the posterior commissure and riMLF, leading to upgaze palsy.

3. Hydrocephalus (fluid build-up in brain)
   Extra fluid can stretch or compress the midbrain from above, causing vertical movement problems, especially upgaze.

4. Midbrain stroke (small artery blockage or bleed)
   A stroke in the upper brainstem can hit vertical eye movement centers, stopping upgaze, downgaze, or both.

5. Thalamic stroke spreading into midbrain connections
   The thalamus sits near important vertical gaze pathways. A stroke here can interrupt those connections.

6. Progressive supranuclear palsy (PSP)
   A degenerative brain disease that often first slows vertical eye movements, then causes fixed up/down palsy, balance problems, stiffness, and falls.

7. Parkinson’s disease and related parkinsonian syndromes
   These conditions sometimes cause slowed vertical saccades and later gaze palsy, especially in atypical forms like PSP or MSA.

8. Multiple system atrophy (MSA)
   Another degenerative disease that can slow vertical eye movements and cause balance and autonomic problems.

9. Niemann-Pick disease type C
   A genetic, metabolic disorder that often shows vertical saccade slowing in children or young adults.

10. Wilson disease (copper buildup)
    Excess copper injures brain areas controlling movement, sometimes affecting vertical gaze and causing movement problems and liver disease.

11. Wernicke encephalopathy (severe vitamin B1 lack)
    Thiamine deficiency injures brainstem regions, sometimes causing eye movement problems, confusion, and unsteady walking.

12. Multiple sclerosis (MS)
    Demyelination (damage to nerve insulation) in the midbrain or MLF may cause vertical (and/or horizontal) eye movement problems.

13. Brainstem or tectal glioma
    A tumor in the midbrain (tectum) can compress vertical gaze centers.

14. Basilar tip aneurysm or other vessel malformation
    A swelling of a brain artery or an abnormal vessel bundle can press on midbrain structures and interrupt vertical signals.

15. Traumatic brain injury (TBI)
    A head injury can bruise or shear the midbrain, causing vertical gaze loss.

16. Autoimmune/paraneoplastic brainstem encephalitis (e.g., anti-Ma2)
    The immune system attacks the brainstem; vertical eye movement can be affected, sometimes linked to cancer elsewhere.

17. Neurosarcoidosis
    Granulomas (inflammatory lumps) can form in the midbrain or nearby pathways and limit vertical gaze.

18. Myasthenia gravis (MG) (a mimic)
    A neuromuscular junction disease where signals from nerves to muscles are weak, causing fatigable vertical movement problems and droopy eyelids.

19. Thyroid eye disease (a mimic)
    Swollen eye muscles (especially inferior rectus) can mechanically block upgaze, looking like a brain problem but actually in the orbit.

20. Orbital blowout fracture with muscle entrapment (a mimic)
    After facial trauma, the inferior rectus muscle can get trapped, blocking upgaze. This is a mechanical problem, not a brain wiring issue.

Symptoms

1. Trouble looking up
   People lift their chin to see high objects. Happens when upgaze signals from the midbrain are blocked.

2. Trouble looking down
   People tilt the head downward to read or see steps. Caused by downgaze pathway damage.

3. Slow vertical eye jumps (slow saccades)
   Quick eye movements upward or downward feel sluggish. This is often an early clue in diseases like PSP.

4. Poor smooth vertical tracking
   Following a moving object up or down feels jerky. The brain cannot coordinate the movement smoothly.

5. Double vision (vertical diplopia) or image misalignment
   The two eyes may not stay aligned vertically; some people tilt their head to line up images.

6. Skew deviation
   One eye sits higher than the other. This is a brainstem imbalance sign.

7. Convergence-retraction nystagmus
   When trying to look up, the eyes can jerk backward or pull inward. A classic Parinaud feature.

8. Light-near dissociation of pupils
   Pupils do not respond well to light but do constrict when focusing on a near object. This points to dorsal midbrain involvement.

9. Eyelid retraction (Collier sign) or droopy lids
   Upper eyelids look pulled up (staring look) in Parinaud, or the lids may droop if other nuclei are involved.

10. Difficulty reading, threading a needle, or using a phone
    Close tasks need frequent downward and upward eye movements. People compensate with head movements.

11. Trouble with stairs or curbs (especially going down)
    Without good downgaze, judging steps is hard, increasing falls.

12. Neck strain from compensating
    Constant chin-up or chin-down positioning can strain the neck.

13. Blurred vision during quick vertical shifts
    Because the eyes cannot land steadily on the target, things blur briefly.

14. Oscillopsia (world seems to move)
    Jerky or unstable eye movement makes the world “bounce” or shake for the person.

15. Other neurological signs depending on the cause
    Examples: unsteady gait, slowness, rigidity, thinking changes (PSP or Parkinsonian disorders), or headache and nausea (tumor, hydrocephalus).

Diagnostic Tests

A) Physical Exam

1. Vertical saccade testing (look quickly between two targets)
   What it is: You’re asked to look quickly from the doctor’s finger at eye level to another finger higher or lower.
   Purpose: Checks the speed and range of up/down jumps of the eyes.
   Meaning: Slow or limited jumps suggest a central (brain) control problem, often supranuclear.

2. Vertical smooth-pursuit testing (follow a moving finger up/down)
   What it is: You track a slow up-down target with only your eyes.
   Purpose: Tests tracking circuits in the midbrain and cerebellum.
   Meaning: Jerky or broken tracking supports a central gaze problem.

3. Optokinetic nystagmus (OKN) stripes moving vertically
   What it is: You look at vertical moving stripes. Normally eyes make a smooth-pursuit plus quick reset pattern.
   Purpose: Confirms whether vertical tracking and quick resets work.
   Meaning: Weak or absent vertical OKN supports vertical gaze pathway damage.

4. Pupil light vs near reaction (light-near dissociation)
   What it is: Doctor checks your pupil with light, then asks you to focus on a near object.
   Purpose: Looks for Parinaud pattern (poor to light, good to near).
   Meaning: Suggests dorsal midbrain involvement.

5. Eyelid position check (Collier sign, lid lag, ptosis)
   What it is: Doctor watches your upper eyelids at rest and during up/down gaze.
   Purpose: Eyelid signs often travel with vertical gaze problems.
   Meaning: Eyelid retraction supports dorsal midbrain syndromes; ptosis may suggest nuclear or nerve involvement.

6. Cover–uncover / alternate cover tests (look for skew)
   What it is: Quickly covering and uncovering each eye checks for vertical misalignment.
   Purpose: Detects skew deviation and vertical diplopia.
   Meaning: Skew often points to a brainstem problem.

B) Manual Tests

7. Oculocephalic reflex (“doll’s-head” maneuver)
   What it is: The clinician gently turns your head up/down while asking you to fix your eyes on a point.
   Purpose: Tests the vestibulo-ocular reflex (VOR), which bypasses higher control centers.
   Meaning: If voluntary up/down movement is poor but VOR moves the eyes, this is supranuclear palsy (control center problem). If VOR also fails, the problem may be nuclear/infranuclear.

8. Head impulse test in the vertical plane
   What it is: Small, quick head tilts up or down while you fixate a target.
   Purpose: Assesses vertical VOR stability.
   Meaning: Helps separate central control issues from peripheral vestibular problems that might mimic poor vertical control.

9. Forced-duction test (checks for mechanical block)
   What it is: With numbing drops, the doctor gently moves the eye with forceps.
   Purpose: If the eye won’t move even when pushed, there is a mechanical block (e.g., entrapment, thyroid eye disease).
   Meaning: Confirms infranuclear, mechanical cause rather than a brain control problem.

10. Fatigability and ice-pack tests (for myasthenia gravis)
    What it is: Look up and hold; the eyelids droop or movement worsens with fatigue; placing an ice pack briefly may improve it.
    Purpose: Screens for myasthenia gravis (a mimic).
    Meaning: Improvement with ice or worsening with fatigue supports MG.

11. Near-response and convergence testing
    What it is: You look from far to near; doctor watches pupil constriction and eye convergence.
    Purpose: In Parinaud, near response may be better than light response; convergence-retraction may appear when trying to look up.
    Meaning: Supports dorsal midbrain involvement.

C) Lab and Pathological Tests

12. Thyroid function tests (TSH, free T4 +/- T3)
    Purpose: Looks for thyroid eye disease, which can mechanically limit upgaze.
    Meaning: Abnormal thyroid hormones + exam/orbit imaging suggests thyroid eye disease rather than a brain cause.

13. Acetylcholine receptor (AChR) and MuSK antibodies
    Purpose: Tests for myasthenia gravis.
    Meaning: Positive antibodies support MG as a mimic of vertical palsy.

14. Copper studies (serum ceruloplasmin, 24-hour urine copper)
    Purpose: Checks for Wilson disease.
    Meaning: Low ceruloplasmin and high urine copper suggest Wilson disease causing eye movement and neurologic issues.

15. Thiamine (vitamin B1) level and nutritional panel
    Purpose: Screens for Wernicke encephalopathy and other nutritional causes.
    Meaning: Low B1 with compatible symptoms supports Wernicke, which can impair eye movements.

D) Electrodiagnostic Tests

16. Video-oculography (VOG) / Electro-oculography (EOG)
    Purpose: Precisely measures eye position and speed during up/down saccades and tracking.
    Meaning: Shows slowed vertical saccades or reduced range, confirming and quantifying the deficit.

17. Single-fiber EMG (SFEMG) for myasthenia gravis
    Purpose: Detects abnormal neuromuscular transmission in tiny muscle fibers.
    Meaning: Increased jitter supports MG, helping explain fatigable vertical weakness.

E) Imaging Tests

18. MRI brain with brainstem focus (T1, T2, FLAIR, DWI)
    Purpose: Looks for stroke, tumor, demyelination, inflammation, or midbrain compression.
    Meaning: Lesions in riMLF, INC, posterior commissure, or nearby areas explain vertical palsy.

19. MR angiography (MRA) or CT angiography (CTA)
    Purpose: Checks for aneurysms or vascular malformations pressing on the midbrain.
    Meaning: Basilar tip aneurysm or other vessels can compress vertical pathways.

20. Orbital CT or MRI
    Purpose: Evaluates eye muscles and bones for entrapment or thyroid muscle swelling.
    Meaning: Confirms mechanical causes of limited upgaze (e.g., inferior rectus enlargement or fracture entrapment).

Regenerative/Stem-Cell–Type” Drug Concepts

There is no proven “regenerative drug” that directly restores vertical gaze pathways on demand. Below are realistic immune and neuro-support avenues; some are investigational.

1. Rituximab (CD20 monoclonal antibody; dosing per protocol such as 375 mg/m² weekly × 4 or 1000 mg day 1 & 15)
   Role: For B-cell–mediated autoimmune encephalitis/demyelination affecting midbrain. Mechanism: Depletes B cells → reduces pathogenic antibodies. Note: Immunosuppression risks.

2. Natalizumab / Ocrelizumab (specialist-guided)
   Role: In selected multiple-sclerosis phenotypes with brainstem involvement. Mechanism: Blocks leukocyte trafficking (natalizumab) or depletes B cells (ocrelizumab). Note: Strict eligibility and monitoring.

3. IVIG (0.4 g/kg/day × 5 days; maintenance as needed)
   Role: Immune modulation when autoantibodies suspected. Mechanism: Fc-mediated immune effects; neutralizes autoantibodies. Note: Headache, thrombosis risk.

4. Erythropoietin (experimental neuroprotection dosing varies in trials)
   Role: Investigational neuroprotection in ischemic/traumatic CNS injury. Mechanism: Anti-apoptotic, pro-angiogenic signaling. Note: Not standard; risk of thrombosis, hypertension.

5. Stem-cell therapies (research trials only)
   Role: Exploratory for neurodegeneration (e.g., PSP) and CNS repair. Mechanism: Potential trophic support or cell replacement. Note: Not approved for VGP; consider only regulated clinical trials.

6. Clemastine or remyelination-oriented agents (investigational in MS)
   Role: Promote oligodendrocyte differentiation. Mechanism: Possible remyelination. Note: Early evidence; not a routine VGP therapy.

Bottom line: Immune therapies help when the cause is immune. “Regenerative/stem cell drugs” are not established for VGP; avoid unregulated clinics.

Surgeries

1. Endoscopic third ventriculostomy (ETV) or ventriculoperitoneal shunt
   Procedure: Create CSF bypass or place a shunt. Why: Relieve hydrocephalus compressing the dorsal midbrain (Parinaud features often improve).

2. Pineal or midbrain tumor resection/biopsy (± radiotherapy/chemotherapy)
   Procedure: Neurosurgical removal or tissue diagnosis. Why: Decompress vertical gaze centers and treat the tumor.

3. Aneurysm or vascular malformation repair (clipping/coiling/cavernoma resection)
   Procedure: Endovascular or open surgery. Why: Prevent rebleed and decompress injured midbrain.

4. Posterior fossa decompression/hematoma evacuation (selected cases)
   Procedure: Surgical decompression of mass effect. Why: Reduce pressure on brainstem gaze pathways.

5. Strabismus surgery (select, stable chronic cases)
   Procedure: Eye muscle repositioning to reduce abnormal head posture or diplopia. Why: Not to “fix” the brain lesion, but to improve comfort and function when neurologic deficit is stable.

When to see a doctor

• Immediately/ER: sudden trouble looking up/down, new double vision with headache, vomiting, severe dizziness, weakness, numbness, trouble speaking, or after head injury—possible stroke/bleed/raised ICP.

• Urgent (within 24–72 h): subacute progression over days, new imbalance or falls, new pupil changes, or suspected infection/autoimmunity.

• Soon (1–2 weeks): chronic symptoms affecting daily life, reading, or stairs; suspected degenerative condition (e.g., PSP).

• Anytime: vision changes worry you or you need rehab/assistive devices.

What to eat and what to avoid

Eat more of:

1. Leafy greens & colorful vegetables (spinach, kale, carrots, peppers).

2. Whole fruits (berries, citrus) for antioxidants and fiber.

3. Whole grains (oats, brown rice, quinoa) for steady energy.

4. Legumes (lentils, beans) for vascular health.

5. Fish (fatty fish 2×/week) for omega-3s.

6. Nuts & seeds (walnuts, flax, chia) in modest portions.

7. Olive oil as main fat.

8. Adequate water (unless fluid-restricted).

9. Low-fat dairy or fortified alternatives for vitamin D/calcium as needed.

10. Herbs/spices (turmeric, garlic) for flavor and anti-inflammatory potential.

Limit/avoid:

1. Excess salt (if hypertensive).

2. Processed meats and trans fats.

3. Sugary drinks and added sugars.

4. Excess alcohol (or avoid entirely if on anticoagulants).

5. Mega-doses of supplements without medical advice (interaction/bleeding risk).

6. Grapefruit if on certain drugs (check interactions).

7. Energy drinks/stimulants that spike blood pressure.

8. Unpasteurized or unsafe foods if immunosuppressed.

9. Very low-carb crash diets (risk of dehydration, electrolyte issues) unless supervised.

10. High-dose vitamin A (neurotoxicity risk) unless prescribed.

Frequently Asked Questions (FAQs)

1. Is vertical gaze palsy a disease by itself?
   No. It is a sign that points to a problem in specific brain areas that control vertical eye movements. Doctors must find the cause.

2. Can VGP get better on its own?
   It depends on the cause. Some causes (small strokes, inflammation treated early, hydrocephalus relieved) can improve. Degenerative causes (like PSP) usually progress.

3. Why can I sometimes move my eyes when my head is turned but not on command?
   That’s reflex sparing. The vestibulo-ocular reflex can still move your eyes because it uses partly different pathways than voluntary commands.

4. Is this the same as a muscle or nerve problem in the eye?
   No. The eye muscles and cranial nerves may be normal. The issue is higher up in the brain’s control centers (supranuclear).

5. Why do doctors order MRI even if CT is normal?
   Because the midbrain is small and complex; MRI can see lesions CT misses (demyelination, tiny strokes).

6. What is Parinaud syndrome?
   A pattern of upgaze palsy with other signs (light-near dissociation, convergence-retraction nystagmus) due to dorsal midbrain involvement—often pineal mass or hydrocephalus.

7. Can glasses fix VGP?
   Glasses cannot repair the brain lesion, but prism lenses can make daily vision tasks easier by redirecting images.

8. Will levodopa fix my eye movements?
   In PSP, levodopa often gives limited benefit, but a trial may help movement and stiffness. Eye movement improvement is variable.

9. Are there exercises to restore vertical gaze?
   Exercises can compensate (training scanning strategies, VOR use) but cannot always restore lost function if pathways are damaged.

10. Is surgery on the eyes helpful?
    Eye muscle surgery may help head posture or double vision when the neurologic problem is stable, but it does not treat the brain lesion.

11. What are red flags for emergency care?
    Sudden onset with headache/vomiting/weakness, decreased consciousness, severe imbalance, or after trauma—call emergency services.

12. Can diet cure VGP?
    No. Diet supports overall brain and vascular health, but you still need cause-specific medical or surgical treatment.

13. Are stem-cell treatments proven for VGP?
    No approved stem-cell therapy exists for VGP. Consider only regulated clinical trials; avoid commercial unproven clinics.

14. How is VGP different from myasthenia gravis?
    Myasthenia is a neuromuscular junction disorder causing fatigable weakness that can mimic gaze limits; tests (ice pack test, antibodies, EMG) and response to edrophonium/pyridostigmine help distinguish it.

15. What is the outlook?
    Prognosis is tied to the cause (e.g., hydrocephalus relief → often improves; degenerative PSP → progressive). Early diagnosis and rehab optimize outcomes.
