Valsalva Retinopathy

Valsalva retinopathy is a sudden bleed in front of the retina (a preretinal hemorrhage) that happens after an intense, brief strain—like a hard cough, vomiting, lifting heavy weight, or bearing down. When you strain against a closed throat (the classic Valsalva maneuver), pressure rises in your chest and belly. That pressure is transmitted to the veins in the head and eyes. The tiny, fragile blood vessels on the surface of the retina can burst from this rapid pressure spike. Blood then collects in a thin potential space just in front of the retina—often under the internal limiting membrane (sub-ILM) or under the posterior hyaloid/subhyaloid—and this pool of blood blocks light, causing sudden, painless blurring or a dark spot in the vision. In many otherwise healthy people, the blood clears on its own over weeks to months and vision returns, especially when the bleed spares the very center of sight (the fovea). EyeWikiNCBIMedscape

Valsalva retinopathy is a sudden bleed inside the back of the eye (the retina) after a forceful strain—like heavy lifting, hard coughing, vomiting, constipation straining, blowing musical instruments, vigorous exercise, or even a strong sneeze with the mouth closed. The strain (called a “Valsalva maneuver”) briefly raises pressure in the chest and head. That pressure surge can rupture tiny fragile retinal capillaries, letting blood leak into the preretinal space (just in front of the retina under the inner limiting membrane, or into the vitreous gel). Vision may blur or a dark red-brown spot, curtain, or central scotoma appears suddenly. In many healthy people, the bleed clears on its own over days to weeks; some large, dense premacular hemorrhages need office-based laser or surgical help to clear faster. Core treatment is observation, avoiding repeat straining, and addressing the trigger.

Types

Doctors don’t use a single, universal staging scale for Valsalva retinopathy. Instead, they describe it using practical “type” labels that tell you where the blood sits, how much blood there is, what part of the retina is affected, and whether it’s one eye or both. These categories help predict symptoms, guide testing, and set expectations.

1. By hemorrhage plane (the layer where the blood sits)

• Sub-ILM hemorrhage: Blood lies just beneath the retina’s inner “skin” (the internal limiting membrane). It often looks like a smooth, round or dome-shaped, sharply demarcated dark red pool.

• Subhyaloid (premacular) hemorrhage: Blood lies between the posterior hyaloid face of the vitreous and the ILM. This can look “boat-shaped”—flat on the top and curved at the bottom—because the blood levels out with gravity.

• Combined: Some eyes have both sub-ILM and subhyaloid blood at the same time. Modern OCT scans help tell these apart by showing the exact layer; subtle signs along the upper border of the blood help discriminate between the two. PMCScienceDirect

2. By location

• Macular (fovea-involving or fovea-sparing): If blood covers the macula—the center of detailed vision—blur is more severe. If it sits next to the fovea and spares the very center, vision may be better.

• Extramacular: Blood away from the macula may cause less central blur but can still create shadows or blind spots.

3. By size (practical description)

• Small: Less than about one optic disc diameter; might cause mild blur or a small spot.

• Medium: About 1–3 disc diameters; vision is usually noticeably blurry.

• Large: More than 3 disc diameters; vision may be very poor until the blood clears.
  (These are descriptive buckets clinicians use at the slit lamp rather than a formal grading system.)

4. By laterality

• Unilateral (one eye): Most common.

• Bilateral (both eyes): Less common, but can happen with very strong or repeated straining or when there’s an added bleeding tendency.

5. By clinical context

• Isolated Valsalva retinopathy in a healthy person: A one-off strain triggers a bleed; the eye exam is otherwise normal.

• Valsalva retinopathy with a risk factor: The same mechanism but with added “fragility,” such as pregnancy, anemia, a bleeding disorder, blood-thinning medication, or diabetic retinopathy. These contexts don’t change the definition but can increase likelihood or severity. EyeWikiNCBI

Causes

Below are triggers that abruptly raise chest/abdominal pressure or involve forceful exhalation against a closed throat—and predisposing situations that make a small vessel more likely to break. Each cause includes a short, plain-language explanation.

1. Forceful coughing – A harsh, repeated cough can spike chest pressure in an instant and rupture a small retinal vessel. Canadian Journal of Ophthalmology

2. Vomiting or retching – Vomiting combines squeezing belly muscles and closing the glottis, creating a high pressure surge. PMC

3. Heavy lifting/weightlifting – Many people hold their breath while lifting (unintentional Valsalva), sharply increasing venous pressure in the head and eyes. Canadian Journal of Ophthalmology

4. Straining with constipation – Bearing down on the toilet is a classic Valsalva maneuver and a well-known trigger. Canadian Journal of Ophthalmology

5. Sneezing fits – Repetitive, explosive sneezes briefly raise intrathoracic pressure and venous pressure. @WalshMedical

6. Labor/childbirth pushing – Prolonged, intense bearing down during vaginal delivery can cause retinal bleeding in rare cases. Canadian Journal of Ophthalmology

7. Pregnancy-related vomiting (hyperemesis) and physiologic changes – Repeated retching plus pregnancy-related blood and vessel changes can predispose to a Valsalva bleed. PMC

8. Vigorous sexual activity with breath-holding/straining – Short bursts of straining may mimic a Valsalva maneuver. IJRCog

9. Playing or practicing wind/brass instruments – Sustained exhalation against resistance can significantly increase venous pressure. (Mechanism consistent with Valsalva strain.)

10. Blowing up balloons – Repetitive, forceful blowing is essentially repeated Valsalva-like efforts.

11. Powerlifting techniques (deadlift/squat) with breath-hold – “Bracing” with a closed glottis maximizes core pressure but also spikes venous pressure in the head.

12. High-effort yoga or calisthenics with breath-holding – Inversions or strenuous poses with breath retention have been reported as triggers. Austin Publishing Group

13. Gagging/retching during upper endoscopy – Procedural retching has triggered Valsalva retinopathy in case reports. PubMed

14. Choking episodes – Struggling exhalation against an obstruction can mimic a severe Valsalva maneuver.

15. Severe asthma or bronchospasm – Repeated forceful exhalation/coughing bouts can act like repeated Valsalva efforts.

16. Obstructive sleep apnea events – Bearing down and repeated pressure swings may contribute in susceptible people.

17. Acute anemia or a bleeding tendency – By itself this does not create pressure, but it lowers the threshold for a vessel to break during even mild strain. Case reports describe Valsalva retinopathy in severe anemia. PubMed

18. Use of blood thinners or platelet-affecting drugs – Anticoagulants/antiplatelets don’t create strain but can increase the size of a bleed after a small rupture.

19. Diabetic retinopathy or fragile retinal vessels – Pre-existing vessel disease can make bleeding more likely with a Valsalva event.

20. Any abrupt breath-hold “against a closed throat” during intense effort – The common pathway across nearly all triggers is the same: a quick spike in intrathoracic/intra-abdominal pressure is transmitted to the eye’s veins, and a superficial retinal capillary gives way. Medscape

Symptoms

These symptoms usually start suddenly and are typically painless. One eye is often affected, but both can be.

1. Sudden, painless blurry vision – The most common complaint; the blur often follows a clear straining event.

2. A central dark spot (central scotoma) – If the blood sits over the fovea, a round or irregular dark area blocks central sight.

3. A “red haze” or “wine-colored film” – Some people describe looking through a reddish or brownish tint when blood is over the macula.

4. Distorted lines (metamorphopsia) – Straight lines may look bent or wavy when the macular surface is covered or pushed forward by a dome of blood.

5. Floaters – Clumps of blood can cast moving shadows that look like spots or threads drifting in the vision.

6. A horizontal “water level” shadow – Large subhyaloid blood can settle and look like a dark shape with a flat top, matching gravity.

7. Reduced reading ability – Small print becomes difficult when fine central vision is blocked.

8. Reduced contrast and color sensitivity – Colors may look washed out or dull when the macula is covered; red-green discrimination can drop.

9. Patchy, off-center blind spots – If blood sits away from the center, a person may notice side shadows or patchy areas of missing vision.

10. One-eye symptom – Covering one eye reveals the difference; the unaffected eye looks “normal,” the affected eye looks dim or blurred.

11. Recent memory of a trigger – Many patients can point to a coughing fit, vomiting episode, or lift right before symptoms started. Medscape

12. No eye pain – Valsalva retinopathy is usually painless; pain suggests a different problem.

13. No light sensitivity – Photophobia is uncommon; if present, clinicians will also look for other causes.

14. Mild headache or face/neck strain history – Related to the triggering exertion rather than the eye bleed itself.

15. Gradual improvement over weeks – As blood slowly clears, the dark spot shrinks and vision returns unless there is staining or damage at the fovea. EyeWiki

Diagnostic tests

Doctors choose tests to confirm the diagnosis, map the blood’s location, measure visual impact, and screen for risk factors that could worsen or recur. Not every person needs every test; your doctor tailors the list based on history and the exam.

A) Physical exam

1. Best-corrected visual acuity (distance and near)
   What it is: Reading letters on a chart with your usual glasses, and then with the best correction the clinic can provide.
   Why it matters: Measures how much the macula is blocked by the hemorrhage; forms a baseline to monitor recovery.

2. Pupil examination (swinging flashlight test)
   What it is: The doctor checks how pupils react to light and compares the two eyes.
   Why it matters: Valsalva retinopathy rarely causes a relative afferent pupillary defect; finding one may point to other problems.

3. Confrontation visual fields
   What it is: Quick bedside mapping of side vision by comparing what the patient sees versus the examiner’s fingers.
   Why it matters: Large or peripheral hemorrhages can create field defects; this is a rapid screen.

4. Intraocular pressure (IOP) measurement—tonometry
   What it is: A gentle measurement of eye pressure (with a puff, handheld tonometer, or the blue light applanation method).
   Why it matters: Very dense premacular blood can occasionally nudge IOP readings; knowing baseline IOP is also useful before any intervention.

5. Slit-lamp biomicroscopy of the anterior segment
   What it is: A microscope exam of the front of the eye—lids, cornea, anterior chamber, iris, and lens.
   Why it matters: Rules out other causes of decreased vision (e.g., corneal edema, anterior chamber bleeding) and checks for signs of systemic disease.

6. Dilated fundus examination with a contact or non-contact lens
   What it is: After dilation, the clinician inspects the vitreous and retina under high magnification.
   Why it matters: This is the heart of diagnosis—seeing a sharply outlined, preretinal pool of blood (often sub-ILM or subhyaloid) in a pattern that fits a Valsalva trigger. mehdijournal.com

B) Manual/bedside functional tests

7. Amsler grid
   What it is: A simple grid to check central vision at home or in clinic.
   Why it matters: Wavy or missing lines correlate with macular involvement and help monitor improvement as the blood clears.

8. Pinhole test
   What it is: Looking through a pinhole mask during visual acuity testing.
   Why it matters: Improves blur from refractive error but not from a dense central hemorrhage; helps confirm the problem is retinal, not optical.

9. Photostress recovery test
   What it is: Brightly illuminating the eye, then timing how long it takes for reading vision to return.
   Why it matters: Prolonged recovery suggests macular dysfunction; dense macular blood often slows recovery.

10. Color vision (Ishihara plates)
    What it is: Number/shape recognition on colored dot plates.
    Why it matters: Macular coverage can reduce color discrimination; color testing provides a sensitive baseline.

11. Red-cap desaturation test
    What it is: Comparing how “red” a red cap looks between the two eyes.
    Why it matters: Subtle macular or optic pathway impact can reduce the vividness of red in the affected eye.

C) Lab and pathological tests

These are supportive and used when the story or the exam suggests an added bleeding risk. Not everyone needs them.

12. Complete blood count (CBC) with platelet count and smear
    Purpose: Looks for anemia or low platelets that could increase bleeding or slow clearing. Case reports link severe anemia with Valsalva bleeds. PubMed

13. Coagulation profile (PT/INR and aPTT)
    Purpose: Screens for clotting problems or over-anticoagulation that could enlarge or prolong a hemorrhage.

14. Fasting blood glucose and HbA1c
    Purpose: Checks for diabetes, which can make retinal vessels fragile and more likely to bleed.

15. Liver function tests
    Purpose: Some liver diseases alter clotting factor production; abnormal results can point to a bleeding tendency.

16. Targeted vitamin levels (e.g., Vitamin C, Vitamin K) or von Willebrand panel when indicated
    Purpose: In recurrent or severe cases without a clear trigger, these help uncover rare nutritional or inherited bleeding issues.

D) Electrodiagnostic tests

These are specialty studies used selectively—often when dense blood blocks the view and your doctor needs to assess retinal function.

17. Multifocal electroretinography (mfERG)
    What it is: A sensitive test that measures local electrical responses from many small areas of the macula.
    Why it matters: Confirms whether the macula itself still functions normally beneath the blood, aiding prognosis.

18. Visual evoked potential (VEP)
    What it is: Measures the brain’s electrical response to visual stimuli.
    Why it matters: If vision is very poor and the retina cannot be seen, VEP helps confirm that signals still reach the brain.

E) Imaging tests

19. Color fundus photography (including wide-field when available)
    What it is: High-resolution pictures of the retina.
    Why it matters: Documents the size, shape, and location of the hemorrhage; serial photos track clearing over time.

20. Optical coherence tomography (OCT)
    What it is: A non-contact scan that creates cross-section “slices” of the retina.
    Why it matters: The key test to pinpoint whether blood is sub-ILM or subhyaloid and to see if the fovea is under the dome of blood. Certain OCT signs near the upper border help separate sub-ILM from subhyaloid hemorrhage. PMC

21. Optical coherence tomography angiography (OCT-A)
    What it is: An OCT-based flow map without dye.
    Why it matters: Usually normal in Valsalva retinopathy but helpful to rule out abnormal new vessels or macular capillary damage.

22. Fluorescein angiography (FA/FFA)
    What it is: Dye is injected in a vein in your arm while retinal photos are taken.
    Why it matters: FA can help exclude other causes of preretinal blood (like new vessels from diabetes). In pure Valsalva retinopathy, FA often shows blocked fluorescence where the blood sits rather than leaking abnormal vessels. EyeWiki

23. Fundus autofluorescence (FAF)
    What it is: Images that show natural fluorescence from retinal pigment.
    Why it matters: Can highlight the edge of a hemorrhage and later reveal any residual macular “staining” after the blood clears.

24. B-scan ocular ultrasound
    What it is: A probe on the closed eyelid sends sound waves to image the eye.
    Why it matters: If the view is completely blocked (dense vitreous hemorrhage), ultrasound confirms retinal attachment and rules out other structural problems.

Regenerative / stem-cell” drugs — what the science says

There are no approved immune-booster, regenerative, or stem-cell drugs for Valsalva retinopathy. In fact, some interventions advertised online can be harmful. Below are six concepts you might see, with clear guidance:

1. Intravitreal stem-cell injections
   Status: Not recommended; potentially dangerous.
   Rationale: Reports of severe inflammation and blindness after unregulated injections. No evidence for Valsalva bleeds.

2. Systemic “immune boosters” (high-dose herbal blends)
   Status: Not proven; can interact with medicines.
   Rationale: No mechanism to resolve preretinal blood; may affect bleeding risk or liver enzymes.

3. Platelet-rich plasma (PRP) into the eye
   Status: Not used for preretinal hemorrhage clearance.
   Rationale: Adds proteinaceous material; no established benefit; potential risks.

4. Growth-factor eyedrops (e.g., EGF/NGF compounds)
   Status: Experimental in other conditions; not indicated here.
   Rationale: No evidence to clear hemorrhage; theoretical risk of aberrant healing.

5. Systemic corticosteroids for isolated Valsalva bleed
   Status: Generally not indicated.
   Rationale: Steroids don’t dissolve trapped blood and may raise glucose/BP—counterproductive.

6. Hyperbaric oxygen
   Status: Not indicated.
   Rationale: No evidence it speeds clearance of premacular hemorrhage; adds cost and logistics.

The safe, evidence-based “active” options—when observation isn’t enough—are office laser membranotomy or surgical techniques below.

---

Procedures/surgeries

(Each: Procedure • Why it’s done • How it works)

1. Nd:YAG hyaloidotomy / ILM membranotomy (office laser)
   Why: Large, dense premacular (sub-ILM or sub-hyaloid) hemorrhage covering the fovea and not clearing quickly; patient needs faster visual recovery (students, pilots, key workers).
   How: A focused laser makes a tiny opening in the posterior hyaloid/ILM so blood drains into the vitreous, where the body can clear it faster.

2. Intravitreal tissue plasminogen activator (tPA) with gas (pneumatic displacement)
   Why: Very dense sub-macular or premacular blood where rapid displacement is desired and laser isn’t suitable.
   How: tPA helps liquefy clot; a gas bubble (e.g., SF6/C3F8) plus positioning moves blood away from the fovea, improving vision while it resorbs.

3. Pneumatic displacement with gas alone (selected cases)
   Why: To float and shift premacular blood off the fovea when tPA is not used.
   How: Injected intraocular gas forms a bubble; patient postures (often face-down or as instructed) so blood migrates inferiorly.

4. Pars plana vitrectomy (PPV)
   Why: Non-clearing vitreous hemorrhage, very large or organized sub-ILM blood, or when other methods are unsuitable or failed.
   How: Microincision surgery removes vitreous gel and trapped blood; surgeon can peel membranes and clear the visual axis.

5. Combined PPV with ILM peeling (selected, surgeon-judged)
   Why: Very stubborn sub-ILM hemorrhages with taut ILM.
   How: Peeling the ILM releases trapped blood and may reduce future traction; used case-by-case.

Procedure choice depends on location of blood (sub-ILM vs sub-hyaloid vs vitreous), size, duration, visual needs, and surgeon preference. All procedures have risks (e.g., retinal tears, infection, pressure spikes), discussed by your retina specialist.

Practical preventions

1. Breathe out during exertion—never hold your breath while lifting.

2. Keep stools soft: fiber, fluids, routine, and only gentle effort.

3. Manage coughs/allergies promptly so you don’t have explosive episodes.

4. Avoid sudden, maximal weightlifting or power moves; build strength gradually.

5. During colds, sneeze with your mouth open into a tissue/elbow.

6. Keep BP and blood sugar in target ranges with your clinician.

7. Follow safe-practice coaching for brass/woodwind playing or scuba/dive work.

8. Review blood-thinner plans with your prescriber before heavy exertion.

9. Avoid smoking/vaping; they impair microvessels and healing.

10. Get early care for vomiting illnesses (food poisoning, pregnancy hyperemesis).

---

When to see a doctor

• Immediately (same day / emergency eye care): Sudden central dark spot or curtain; severe vision drop; flashes/floaters like “soot shower”; eye pain; vision not improving; vision worse after a new coughing/lifting episode; vision loss after head/eye trauma.

• Soon (within days): Known small bleed but you rely on sharp central vision for work/school; you have one good eye only; you are on anticoagulation; you’re pregnant; you have diabetes or very high BP.

• Routine follow-up: Your eye doctor gave an observation plan and symptoms are improving as expected.

What to eat and what to avoid

What to eat”:

1. Water—steady sips through the day.

2. Fiber-rich foods (oats, legumes, vegetables, fruits like prunes/kiwi).

3. Leafy greens (lutein/zeaxanthin sources).

4. Citrus/berries (vitamin C, bioflavonoids).

5. Fish 1–2×/week (natural omega-3s).

6. Nuts/seeds (magnesium, vitamin E—within daily limits).

7. Whole grains (steady energy, fiber).

8. Fermented dairy/yogurt (gut regularity for some).

9. Olive-oil–based meals (cardiometabolic health).

10. Small, bland meals during nausea (bananas, rice, toast, applesauce).

What to avoid or limit”:

1. Heavy alcohol (bleeding and liver risk).

2. High-salt processed foods (worsens BP).

3. Very spicy/acidic meals during active nausea (triggers retching).

4. Excess caffeine/energy drinks (BP/HR surges for some).

5. Smoking and nicotine products (microvascular harm).

6. Ultra-low-fiber diets (constipation/straining).

7. Mega-doses of vitamin E or fish oil without medical advice (may affect bleeding).

8. Unregulated “blood thinning” herbs/supplements before exertion.

9. Crash dieting/dehydration.

10. Any supplement promising to “dissolve eye blood” (red flag).

Frequently asked questions

1. Will it go away by itself?
   Often yes. Small-to-moderate bleeds commonly clear over days to weeks. Your doctor monitors with exams/OCT.

2. Can I go blind from this?
   Permanent severe loss is uncommon when it’s a straightforward Valsalva bleed and you avoid re-straining. But large premacular bleeds sitting on the fovea for long can damage photoreceptors—this is why timely review matters.

3. How do I know if the blood is in front of or inside the retina?
   Your ophthalmologist uses exam and OCT imaging to identify sub-ILM/sub-hyaloid vs vitreous locations—this guides treatment.

4. Why did it happen to me if I’m healthy?
   Even healthy capillaries can pop under sudden pressure spikes. Some people have a one-off event after an intense trigger.

5. Do I need glasses or eye drops to cure it?
   Glasses won’t clear the blood. Drops are only used selectively (e.g., if eye pressure rises). Time, trigger control, and sometimes a procedure are the keys.

6. Is it the same as diabetic retinopathy?
   No. Diabetic retinopathy is a chronic disease with abnormal vessels and leakage. Valsalva retinopathy is an acute pressure-spike bleed in an otherwise normal retina.

7. Can I fly?
   Commercial flying is usually fine for uncomplicated cases. If you have a gas bubble after a procedure, do not fly until your surgeon clears you.

8. When can I lift weights again?
   Typically after your doctor confirms stability. Restart with lower weights, higher reps, and continuous breathing—never breath-hold.

9. Will the blood stain my retina?
   Prolonged dense blood on the fovea can be toxic. If large and central, your doctor may suggest laser or surgery to speed clearance.

10. Are NSAIDs safe for pain?
    Prefer acetaminophen first. NSAIDs (e.g., ibuprofen) can affect platelets and bleeding; ask your clinician before use.

11. I’m on warfarin/DOAC/antiplatelet therapy—what now?
    Never stop on your own. Your eye doctor and prescriber will balance bleeding vs clotting risk and advise.

12. Could high blood pressure cause it?
    Acute surges contribute. Long-term BP control protects microvessels and lowers recurrence risk.

13. What if it keeps happening?
    Recurrent events prompt a deeper search for chronic cough, severe constipation, blood disorders, or medication contributors—your doctor may coordinate with primary care/hematology.

14. Will a laser harm my macula?
    The laser aims at the membrane over the blood, not the photoreceptors, using carefully chosen energy. Risks exist but are low in experienced hands, and benefits can be rapid vision return.

15. How will I know it’s getting better?
    Vision gradually clears; the dark spot shrinks/fades. Follow-up photos and OCT will show decreasing blood and restored foveal contour.
