Vortex Vein Varix (Vortex Vein Varicosity)

A vortex vein varix is a localized, balloon-like widening of a vortex vein, which is one of the large choroidal drainage veins inside the eye. The choroid is the vascular layer that sits between the retina and the white wall of the eye (sclera). Blood from the choroid drains through several “vortex” veins that spiral out through the sclera toward the outer surface of the eye and then into the superior and inferior ophthalmic veins.

A vortex vein varix (also called vortex vein varicosity or choroidal varix) is a benign balloon-like widening of a vortex vein ampulla—one of the main drainage veins of the choroid (the vascular layer under the retina). It usually sits near the equator of the eye and can look like a round, dark, slightly elevated spot under the retina. Importantly, this spot changes with body position, eye position, or gentle pressure on the eye, sometimes filling and looking raised, and other times flattening or disappearing. That dynamic behavior is the key clue that it is not a tumor (like choroidal melanoma) but a harmless venous dilation. Most patients have no symptoms, and the condition is often found by chance during a routine dilated exam or widefield imaging. EyeWiki+1Retina TodayRetina Image Bank

In a varix, a short segment of this venous channel becomes abnormally distended but still communicates with the rest of the vein. Because it is a thin-walled venous pouch, its size can change with body position, breath-holding, straining (Valsalva), or jugular pressure, all of which alter venous pressure. On a dilated eye exam, a vortex vein varix typically looks like a bluish-gray, dome-shaped, soft elevation in the fundus (usually in the mid-periphery), often expanding with Valsalva and collapsing when the patient sits up or relaxes.

Most cases are benign and asymptomatic. The big clinical challenge is not to mistake a vortex vein varix for a choroidal melanoma, metastasis, hemangioma, or other mass. Imaging and simple positional testing help confirm the diagnosis. True complications are uncommon, but the varix can occasionally thrombose (develop a clot) or bleed, causing visual symptoms.

Types

1. Idiopathic (primary) varix
   The varix develops without a clear external cause. The venous wall in a short segment is weak or compliant, so it balloons when venous pressure rises and shrinks when it falls.

2. Positional (intermittent) varix
   The varix is minimally visible at rest but enlarges with posture changes (e.g., bending over, lying down) or with Valsalva, then collapses again when the provoking factor stops.

3. Persistent (non-collapsible) varix
   The dilation is present at baseline and changes less with position. Often reflects a larger or more rigid pouch, longstanding venous wall remodeling, or chronically elevated venous pressure.

4. Compressive (secondary) varix
   Outflow from the orbit is hindered by external compression (e.g., an orbital mass such as a cavernous hemangioma, thyroid eye disease crowding, or a neck mass compressing jugular veins). The backup pressure dilates the vortex vein segment.

5. Thrombosed varix
   The pouch develops a venous clot, becoming firmer, possibly tender, and less responsive to position. It can trigger local inflammation, edema, or hemorrhage.

6. Complicated varix with hemorrhage
   The dilated vein leaks or ruptures, causing subretinal or intraretinal bleeding. Patients may notice a sudden floater, a dark spot, or blurred vision.

7. Unilateral vs bilateral varix
   Most are unilateral; bilateral cases raise the possibility of generalized venous or outflow problems (e.g., cardiopulmonary disease or jugular vein issues).

8. Ampullary (ampulla-type) varix
   The dilation sits at the ampulla, where multiple choroidal venules join before exiting the sclera; appears as a rounded, compressible pouch.

9. Segmental (channel-type) varix
   A longer, tubular portion of the vortex vein is affected rather than a saccular pouch.

10. Associated-orbital-varix phenotype
    The eye finding coexists with orbital venous varices (abnormally distensible orbital veins) that can cause intermittent proptosis (eye bulging) with Valsalva.

---

Causes

1. Congenital venous wall laxity
   Some people are born with slightly weaker or more elastic venous walls, allowing a portion of a vortex vein to balloon under pressure.

2. Normal anatomic variance in outflow patterns
   The choroidal venous tree varies among people; a dominant drainage pathway can face higher flow and pressure, predisposing a segment to dilate.

3. Valsalva and strain (coughing, heavy lifting, constipation)
   Forceful exhalation against a closed glottis raises chest and venous pressure, temporarily engorging ocular veins and expanding a susceptible pouch.

4. Frequent head-down positions
   Work or exercise with bending or inverted postures (e.g., certain yoga inversions) increases episcleral/jugular venous pressure, expanding the varix.

5. Obesity with elevated intrathoracic pressure
   Extra body mass can raise central venous pressure and reduce venous return, encouraging episcleral venous hypertension and varix enlargement.

6. Obstructive sleep apnea
   Nighttime intrathoracic pressure swings and hypoxia can increase venous pressures, contributing to distensible venous segments.

7. Right-sided heart disease (e.g., tricuspid regurgitation, pulmonary hypertension)
   These conditions elevate central venous pressure and can transmit higher pressure to orbital/choroidal veins.

8. Superior vena cava (SVC) obstruction
   SVC syndrome from thrombosis or tumor compression obstructs venous return from the head and neck, engorging ocular veins.

9. Internal or external jugular vein obstruction or compression
   Thrombosis, catheter-related scarring, or large neck masses impede outflow, raising pressure back to the orbit and eye.

10. Carotid-cavernous fistula (direct or dural)
    Abnormal arterial-to-venous shunting into the cavernous sinus elevates venous pressure in ophthalmic veins, distending choroidal outflow channels.

11. Cavernous sinus thrombosis
    A clot in the cavernous sinus blocks venous drainage from the orbit, producing venous congestion that can enlarge vortex vein segments.

12. Thyroid eye disease
    Orbital tissue enlargement compresses venous pathways, raising episcleral venous pressure and favoring varix formation or enlargement.

13. Orbital mass (e.g., cavernous hemangioma, schwannoma)
    Space-occupying lesions impede venous egress or distort the vortex vein pathway, leading to focal dilation.

14. Hyperviscosity syndromes (polycythemia, Waldenström macroglobulinemia)
    Thicker blood flows sluggishly and elevates venous pressure, making a compliant venous segment dilate.

15. Pregnancy
    Increased blood volume and venous capacitance can transiently engorge ocular veins; susceptible segments may balloon.

16. Chronic cough or COPD
    Repeated intrathoracic pressure spikes elevate venous pressure, promoting venous distensibility in the choroid.

17. Post-surgical venous changes (e.g., after scleral buckling)
    Altered scleral geometry or scarring can redirect or narrow venous exit channels, causing upstream dilation.

18. Idiopathic intracranial hypertension (IIH)
    Elevated intracranial venous pressures can transmit to the orbital veins, producing choroidal venous engorgement.

19. Systemic hypertension with episcleral venous hypertension
    While arteries are the main target, some patients develop elevated episcleral venous pressure, which can enlarge venous pouches.

20. Local venous injury or inflammation
    Focal phlebitis or micro-trauma may weaken a venous wall, creating a site of compliant dilation.

Symptoms

1. No symptoms at all
   Many varices are incidental findings on a routine dilated exam.

2. Transient blurred vision
   Vision can briefly blur during Valsalva, bending, or strenuous effort, then clear when venous pressure normalizes.

3. A small gray shadow or spot
   If the varix lies near the macula or causes local retinal changes, some people notice a fixed smudge or paracentral dark spot.

4. Positional visual change
   Bending over or lying flat may trigger a temporary change in clarity or a sense of “fullness” in the eye.

5. Metamorphopsia (wavy lines)
   Mild retinal contour changes overlying a varix can make straight lines look slightly wavy, especially on an Amsler grid.

6. Floaters
   If a small bleed occurs in the retina or vitreous, people can see moving specks or cobwebs.

7. Photopsia (brief light flashes)
   Mechanical tugging on the retina over an enlarged vein can sometimes cause tiny flashes.

8. Scotoma (blind spot)
   Rarely, overlying retina becomes compressed or altered, creating a small area of reduced sensitivity.

9. Eye pressure or fullness sensation
   During venous engorgement, patients may describe a dull pressure without true pain.

10. Headache with straining
    If venous issues are systemic, head pressure or headache may accompany eye symptoms during Valsalva.

11. Intermittent redness
    Episcleral veins can become more visible during engorgement episodes.

12. Mild ache with thrombosis
    A thrombosed varix can feel tender and make the eye sore.

13. Sudden blur from hemorrhage
    A subretinal or intraretinal bleed near the macula can cause acute vision drop.

14. Worse vision in certain positions
    Symptoms may be clearly position-dependent (e.g., worse when supine).

15. Proptosis with orbital varices (associated)
    If orbital venous varices coexist, the eye can bulge intermittently with Valsalva or bending.

Diagnostic tests

A) Physical examination

1. Comprehensive history and symptom mapping
   The clinician asks about onset, triggers (Valsalva, bending, exercise), and systemic issues (heart, lung, thyroid, neck masses, sleep apnea). Position-dependent symptoms strongly suggest a venous problem.

2. Visual acuity and refraction
   Basic measures to capture baseline vision and exclude refractive blur. Stability suggests a benign lesion without macular involvement.

3. Pupil exam and color vision
   Checks for relative afferent pupillary defect and color desaturation, which would hint at optic nerve or macular disease—usually absent in simple varix.

4. Slit-lamp and dilated fundus exam with indirect ophthalmoscopy
   The cornerstone. The examiner looks for a bluish-gray, dome-like choroidal elevation in the mid-peripheral fundus that expands with Valsalva and collapses upright; absence of lipofuscin clumps, orange pigment, drusen-like changes, or intrinsic solid mass features helps distinguish it from melanoma or hemangioma.

5. External exam and exophthalmometry (if indicated)
   If orbital varices or outflow problems are suspected, measuring proptosis and observing episcleral venous congestion adds clues.

B) Manual tests (simple bedside maneuvers)

6. Valsalva provocation during ophthalmoscopy (clinician-guided)
   With safe instruction, the patient bears down gently. A true vortex vein varix visibly enlarges; when the patient relaxes, it shrinks. This dynamic behavior is highly suggestive.

7. Posture testing (supine vs sitting vs head-down)
   The lesion is observed lying down and sitting up. Expansion supine and collapse upright support a venous varix.

8. Gentle jugular vein compression test (specialist-only, with caution)
   Temporary jugular outflow impedance increases orbital venous pressure; transient enlargement of the lesion favors varix. (This should only be done by trained clinicians and avoided in carotid disease or elevated intracranial pressure.)

C) Laboratory and pathological tests

9. Complete blood count and hematocrit/hemoglobin
   Screens for polycythemia or anemia. High hematocrit can raise viscosity, promoting venous engorgement.

10. Serum viscosity or protein electrophoresis
    Evaluates hyperviscosity conditions (e.g., Waldenström macroglobulinemia) that can worsen venous congestion.

11. Coagulation profile (PT/INR, aPTT) and D-dimer if thrombosis suspected
    Helps assess clotting tendency and investigate suspected varix thrombosis or systemic thrombotic disorders.

12. Thyroid function tests
    Screens for thyroid eye disease associations that can compress orbital veins.

13. Inflammatory/infectious screens when differential is unclear
    ESR/CRP, syphilis serology, TB testing may be used to exclude inflammatory or infectious choroidal lesions mimicking a mass.

D) Electrodiagnostic tests

14. Full-field ERG (electroretinography)
    Usually normal in a benign varix; used if wider retinal dysfunction is suspected or to exclude diffuse retinal disease.

15. Multifocal ERG or EOG (electro-oculography)
    If the lesion lies near the macula or if subtle photoreceptor dysfunction is suspected, these can help. Normal or near-normal results back a benign venous cause.

E) Imaging tests

16. Color fundus photography (including widefield)
    Documents the appearance and size at rest and after provocation; serial photos show dynamic change rather than growth—a key melanoma distinction.

17. Optical coherence tomography (OCT, ideally enhanced-depth imaging or swept-source)
    Provides cross-sectional views: a smooth choroidal elevation with intact overlying retina and RPE, minimal intraretinal edema, and a hyporeflective choroidal cavity consistent with a venous pouch. EDI or swept-source better shows choroidal depth.

18. OCT angiography (OCT-A)
    Maps slow flow patterns. A varix may show low-signal venous channels without the solid, dense flow pattern seen in vascular tumors; helps rule out choroidal neovascularization.

19. B-scan ultrasonography with (if available) color Doppler
    Shows a compressible, low-to-medium reflectivity elevation that changes with Valsalva; Doppler can demonstrate venous flow within the pouch, supporting the diagnosis.

20. Fluorescein angiography (FA) and Indocyanine green angiography (ICGA)
    FA may be nonspecific; ICGA is more helpful for choroidal circulation, showing a filling venous sac without the early, intense hyperfluorescence pattern of a choroidal hemangioma or the intrinsic circulation pattern of melanoma. Dynamic sequences can capture size change with maneuvers.
    (CT/MRI/MRV of the orbit and brain are reserved for cases with red flags—proptosis, bruit, cranial neuropathies—when a carotid-cavernous fistula, cavernous sinus thrombosis, or orbital mass is suspected.)

Non-pharmacological treatments (therapies & practical care)

1. Reassurance and education: explain that this is a benign venous dilation, not a cancer, and that its on-off appearance is normal. Purpose: reduce anxiety and prevent unnecessary procedures. Mechanism: informed consent and understanding. Retina TodayEyeWiki

2. Document the dynamic sign: obtain photos/videos in filling and flattened states. Purpose: future comparisons; Mechanism: proves venous behavior. Retina Image Bank

3. Scheduled observation: periodic dilated exam and OCT/ICGA if needed. Purpose: ensure stability; Mechanism: surveillance. PMC

4. Avoid unnecessary biopsy: strongly discourage invasive diagnostics when classic dynamic features are present. Purpose: safety; Mechanism: risk avoidance. Retina Today

5. Trigger management (Valsalva): advise gentler breathing during lifting/straining; treat constipation to avoid straining. Purpose: reduce venous spikes; Mechanism: lower episcleral/choroidal venous pressure. Retina Today

6. Posture awareness: if the lesion only appears when supine, reassure; no special restriction is required. Purpose: reduce worry; Mechanism: education. Retina Image Bank

7. Shield from misdiagnosis: include the diagnosis and dynamic photos in the chart/letters so other providers don’t mistake it for melanoma. Purpose: continuity of care.

8. Stress reduction if the eye has a pachychoroid tendency (e.g., history of CSC). Purpose: possibly lower sympathetic/venous load; Mechanism: lifestyle balance. PMC+1

9. Sleep hygiene & screen for sleep apnea if vascular congestion symptoms are present (snoring, daytime sleepiness). Purpose: reduce nocturnal venous surges; Mechanism: better oxygenation/less Valsalva-like strain. (Physiology-based supportive step).

10. Blood pressure control (general cardiovascular health). Purpose: healthier choroidal perfusion; Mechanism: fewer peaks. (General vascular principle.)

11. Stop smoking. Purpose: better microvascular health; Mechanism: reduces endothelial dysfunction. (General ocular vascular health.)

12. Eye-rub avoidance and avoid prolonged external compression (tight goggles, VR headsets that press). Purpose: reduce local venous pressure spikes. (Dynamic pressure principle.)

13. Healthy hydration: avoid extremes (dehydration → viscosity; overhydration → venous load). Purpose: stable hemodynamics. (General vascular principle.)

14. Blue-light/contrast optimization in near tasks if near macula (rare need). Purpose: comfort; Mechanism: visual ergonomics.

Drug treatments

There is no routine medication for vortex vein varix itself.
Drugs are only considered if there is a separate condition present (for example, secondary choroidal neovascularization, or a coexisting pachychoroid/CSC problem). Most patients need no drugs at all. EyeWikiPMC

Below are conditional examples to show what might be used for associated issues, not for the varix per se. Do not self-start; these are specialist-directed:

1. Anti-VEGF injections (e.g., ranibizumab, aflibercept) – if secondary CNV ever develops (very rare). Purpose: stop CNV leakage; Mechanism: VEGF inhibition; Typical schedule: monthly loading then PRN; Side effects: transient discomfort, rare endophthalmitis. (General CNV evidence.)

2. Photodynamic therapy (verteporfin) – not for varix, but sometimes used in pachychoroid/CSC when indicated. Mechanism: selective vascular modulation; Risks: photosensitivity. PMC

3. Mineralocorticoid receptor antagonists (e.g., eplerenone) – considered in some CSC protocols; not for varix itself. Mechanism: choroidal vascular modulation; Side effects: hyperkalemia. (CSC literature, evolving.) PMC

4. Topical/Oral IOP-lowering agents – not indicated unless there is a separate glaucoma/IOP issue. Mechanism: reduce pressure load.

5. Antihypertensives – for systemic BP control (general health), not as a direct varix therapy.

6. Lipid-lowering therapy – cardiovascular risk reduction; indirect ocular benefits only.

7. Antireflux/asthma meds if chronic cough is provoking Valsalva (indirect).

8. OSA therapy (CPAP) – a device, not a drug, but sometimes accompanied by meds; aims at nocturnal breathing stability (indirect).

9. Smoking-cessation pharmacotherapy (varenicline, NRT) – general vascular health.

10. Anxiolytics/CBT (non-drug first) if fear of “melanoma” causes major distress—prefer non-drug strategies first.

Dietary molecular supplements

No supplement is proven to shrink or “cure” a vortex vein varix.
The items below are general eye-/vascular-health supports used in other conditions. Discuss with your doctor, especially if you have kidney disease, are pregnant, or take blood thinners.

1. AREDS2 antioxidant formula (vitamins C, E, lutein, zeaxanthin, zinc, copper) – used for AMD risk reduction; typical per-capsule amounts per labeling; may support retinal oxidative balance.

2. Omega-3 fatty acids (EPA/DHA) ~1 g/day – cardiovascular and endothelial support; watch for bleeding risk at high doses.

3. Magnesium 200–400 mg/day – smooth muscle/vascular tone; avoid in renal failure.

4. Coenzyme Q10 100–200 mg/day – mitochondrial/vascular support (mixed evidence).

5. L-citrulline/L-arginine (vascular NO pathway) – may enhance endothelial function; avoid if hypotensive/migraine-prone.

6. Bilberry/anthocyanins standardized extract – antioxidant/vascular support (evidence modest).

7. Curcumin 500–1,000 mg/day – anti-inflammatory effects; interacts with anticoagulants.

8. Vitamin D per deficiency status – overall health; do not exceed safe limits.

9. Resveratrol 100–250 mg/day – endothelial signaling; limited ocular evidence.

10. Probiotics – indirect systemic inflammation modulation.

(Again, these do not treat the varix; they support general vascular health.)

Regenerative / stem-cell drugs

None are indicated. There are no regenerative or stem-cell therapies for vortex vein varix. Such treatments are experimental for other eye diseases and should not be used for this benign venous finding. If you see claims online, be cautious and consult a retina specialist. (Consensus from reviews/guidelines; condition is benign and observed.) EyeWiki

---

Surgeries or procedures

1. Surgery on the varix itself – not done. There is no role for cauterizing or ligating a vortex vein varix.

2. Diagnostic biopsy – avoided. A dynamic, compressible lesion with classic angiography should not be biopsied because of bleeding risk and because imaging already gives the diagnosis. Retina Today

3. Enucleation – absolutely not for a proven varix.

4. Laser photocoagulation – not for varix. It does not address the venous dilation.

5. Photodynamic therapy – only for other diseases (e.g., selected pachychoroid/CSC or CNV) and not for an uncomplicated varix. PMC

Preventions

You cannot fully prevent a naturally variant venous ampulla, but you can reduce venous spikes and keep overall vascular health strong:

1. Avoid forceful Valsalva (heavy straining); use proper lifting technique. Retina Today

2. Treat constipation/chronic cough to limit repeated straining.

3. Manage blood pressure and cardio-metabolic risk.

4. Stop smoking.

5. Maintain healthy weight and exercise regularly (as cleared by your doctor).

6. Optimize sleep; evaluate sleep apnea if suspected.

7. Avoid tight external eye pressure (goggles/headgear); don’t rub eyes.

8. Keep hydration steady (avoid extremes).

9. If you have pachychoroid/CSC history, be careful with steroids and discuss alternatives. PMC

10. Keep regular eye check-ups with documentation images.

When to see a doctor

• Right away (urgent) if you notice sudden vision loss, a new dark curtain, many new floaters/flashes, eye pain, or new distortion near the center of vision.

• Soon (within days–weeks) if the known lesion looks different than usual, you develop new central blur, or if another clinician raises concern for a tumor.

• Routine follow-up: as your retina specialist recommends (often 6–12 months) to reconfirm stability with photos/OCT ± ICGA. PMC

---

What to eat and what to avoid

Eat more:

• Leafy greens & colored vegetables (lutein/zeaxanthin, antioxidants)

• Fish (fatty fish 1–2×/week for omega-3s)

• Fruits, legumes, whole grains, nuts (fiber and vascular health)

• Olive oil & other unsaturated fats

Limit/avoid:

• Smoking (not a food, but crucial)

• Excess salt, trans fats, ultra-processed snacks, sugary drinks

• Excess alcohol

• High-dose supplements without medical advice (especially if you take anticoagulants or have kidney issues)

(Diet supports overall vascular health; it does not “shrink” a venous varix.)

Frequently Asked Questions (FAQ)

1. Is a vortex vein varix cancer?
   No. It’s a vein dilation, not a tumor. The dynamic collapse/filling helps confirm it’s venous, not malignant. Retina Today

2. Why does it look like a mass?
   Because the dilated vein can raise the choroidal surface and look pigmented. Imaging shows the venous lumen. PubMed

3. Can it go away by itself?
   Sometimes the appearance changes over time, and there are reports of spontaneous resolution. Many remain stable for years. PMC

4. Do I need treatment?
   Usually no. Observation and documentation are standard. EyeWiki

5. Could it affect my vision?
   Rarely. If near the macula or if RPE changes occur, you may notice subtle symptoms. Most people have normal vision. PMC+1

6. How do doctors confirm the diagnosis?
   By showing dynamic behavior (gaze/posture/pressure) and using ICGA, OCT/EDI-OCT, B-scan to confirm venous features and exclude tumors. PubMed+1

7. Can it turn into melanoma?
   No—it is not a precursor to melanoma. The problem is mistaking one for the other; proper imaging prevents that. Retina Today

8. Will exercise make it worse?
   Normal exercise is fine. Avoid forceful Valsalva/breath-holding with heavy lifts. Retina Today

9. Is there a medicine or vitamin to fix it?
   No medicine or vitamin has been proven to shrink a varix. Supplements may support general vascular health only.

10. What about eye pressure?
    Routine IOP checks are fine; pressure changes can influence venous filling but are not the cause in most cases. EyeWiki

11. Can pregnancy affect it?
    Pregnancy changes venous dynamics; visibility may vary. No special treatment is needed unless you have symptoms (rare).

12. Should I worry if it looks bigger some days?
    Dynamic size is expected. Report new, persistent changes or new symptoms for re-evaluation. Retina Today

13. Is it common in high myopia?
    Posterior vortex variants are linked with high myopia/posterior staphyloma. PMC

14. Could it be related to pachychoroid/CSC?
    Vortex vein congestion and intervortex anastomoses are part of pachychoroid physics; the varix may coexist in that setting. PMCPubMed

15. How often should I follow up?
    Commonly every 6–12 months, customized to your eye and clinician judgment. PMC
