Roth Spots

Roth spots are small bleeds inside the retina—the light-sensitive tissue at the back of the eye—with a pale or white center in the middle of the bleed. The white center is usually made of clotted fibrin and platelets, or sometimes white blood cells, bits of bacteria, or dead tissue. The bleed itself sits in the nerve fiber layer of the retina, so it can look flame-shaped or round depending on the layer and direction of the nerve fibers. In simple words, a Roth spot is a tiny red spot with a white dot in the middle on the back wall of the eye.

Roth spots are not a disease by themselves. They are a sign that something is stressing or damaging the small blood vessels in the retina or the blood itself. They often mean there is inflammation, infection, clotting problems, high blood pressure, diabetes damage, or low blood counts. Because they can point to serious illnesses—especially infective endocarditis (a heart valve infection)—doctors take them seriously. Sometimes they cause no eye symptoms at all and are found during a routine eye exam. Sometimes they happen with blurred vision or a small dark spot in the vision if they sit near the center of sight.

Roth spots are tiny retinal hemorrhages with a pale or white center that an eye doctor can see when they looks at the back of the eye (the retina) with special lenses. The red rim is a small bleed under the inner surface of the retina. The white center is usually a mix of clotted platelets and fibrin, sometimes with trapped immune cells or damaged tissue. Roth spots are not a disease by themselves. They are a warning sign that the blood vessels or the blood itself are under stress somewhere in the body.

Roth spots were first linked to infective endocarditis (a heart valve infection) because bacteria and tiny clots can break off from an infected valve and travel to the eye, causing these small retinal “micro-infarcts.” Today we know they can also appear with severe anemia, leukemia, poorly controlled diabetes, high blood pressure, autoimmune vasculitis, HIV infection, sepsis, preeclampsia, and severe trauma (such as Purtscher retinopathy). Most Roth spots fade on their own once the underlying problem is treated. They rarely cause permanent vision loss by themselves, but they matter because they point to a potentially serious systemic condition that needs attention.

How a Roth spot forms (simple mechanism): a tiny retinal capillary is injured or blocked. Blood leaks out and forms a small hemorrhage. In the center of the hemorrhage, a fibrin-platelet plug or other pale material settles, making the white center. As the body heals, the blood is slowly reabsorbed. The white core may fade last. If the cause is treated, Roth spots usually resolve over weeks to months.

Types

1. By cause

• Infectious-related Roth spots: often from infective endocarditis or severe sepsis, where septic micro-emboli injure retinal vessels.

• Hematologic (blood) Roth spots: from leukemia, severe anemia, low platelets, or clotting disorders that make vessels fragile or bleeding more likely.

• Vascular/metabolic Roth spots: from diabetes or high blood pressure, where small vessels are chronically damaged.

• Autoimmune/vasculitic Roth spots: from diseases like lupus or ANCA-associated vasculitis that inflame and narrow small vessels.

• Embolic/traumatic Roth spots: from fat embolism, Purtscher retinopathy after chest trauma, or other embolic events.

• Nutritional/toxic/hypoxic Roth spots: from scurvy (vitamin C deficiency) or severe hypoxia (like carbon monoxide exposure).

• Iatrogenic Roth spots: linked to chemotherapy-induced low platelets or strong blood thinners.

2. By appearance

• Flame-shaped white-center hemorrhage: follows the nerve fiber layer pattern.

• Round or blot-type white-center hemorrhage: deeper location, more dot-blot like.

• Macular vs peripheral Roth spots: near the center of vision vs towards the edges.

• Single vs multiple: one spot vs many spots, which can hint at systemic severity.

3. By time course

• Acute Roth spots: new, bright red with a sharp white center.

• Resolving Roth spots: fading red, shrinking white core, sometimes leaving a tiny scar or none.

Causes

1. Infective endocarditis
   A bacterial infection grows on a heart valve and throws tiny infected clots into the bloodstream. These micro-emboli can reach the retina, injure small vessels, bleed, and form white-center spots.

2. Sepsis or severe bloodstream infection
   Widespread infection triggers inflammation and clotting, which damages fragile retinal capillaries and causes white-centered hemorrhages.

3. Leukemia (especially acute types)
   Abnormal white blood cells crowd the marrow and spill into blood. They make vessels leaky and change blood flow, leading to retinal hemorrhages with white centers that may include leukemic cells or fibrin.

4. Severe anemia
   Very low red blood cell levels reduce oxygen delivery and make retinal vessels fragile, so small bleeds happen more easily, sometimes with fibrin centers.

5. Thrombocytopenia (low platelets) or platelet dysfunction
   If there are too few platelets or they do not work well, tiny bleeds occur in the retina and may show white cores of fibrin or cellular debris.

6. Disseminated intravascular coagulation (DIC)
   Uncontrolled clotting uses up platelets and factors, causing bleeding in many places, including the retina, with white-center hemorrhages.

7. Diabetic retinopathy
   High sugar damages small vessels over years. Fragile new vessels or leaky capillaries can bleed and form Roth-like spots with pale centers.

8. Hypertensive retinopathy
   Long-standing high blood pressure stresses and narrows retinal arterioles. Weak points bleed and can leave white-center hemorrhages.

9. Systemic lupus erythematosus (SLE)
   Autoimmune attack inflames small vessels (vasculitis), blocks blood flow, and causes hemorrhages with pale centers.

10. ANCA-associated vasculitis (e.g., GPA)
    Inflamed small vessels in many organs, including the retina, can rupture and bleed, forming white-center lesions.

11. Antiphospholipid syndrome (APS)
    Sticky blood and small clots block retinal capillaries. The injured vessels bleed and build a fibrin-platelet core in the center.

12. HIV retinopathy or opportunistic infections
    Low immunity allows infections and microvascular damage, leading to retinal hemorrhages with white centers.

13. Purtscher retinopathy (after chest trauma, acute pancreatitis, or compression injuries)
    Emboli and complement activation injure retinal capillaries abruptly, causing hemorrhages and white lesions that can include Roth spots.

14. Fat embolism syndrome
    After long-bone fractures or orthopedic surgery, fat droplets enter blood, lodge in retinal vessels, and cause white-center hemorrhages.

15. Shaken baby syndrome / abusive head trauma
    Severe acceleration-deceleration forces tear small retinal vessels, creating multiple hemorrhages, sometimes with Roth spots.

16. Preeclampsia/eclampsia
    Pregnancy-related high blood pressure and endothelial stress can leak and bleed in the retina, forming white-centered hemorrhages.

17. Scurvy (vitamin C deficiency)
    Weak collagen in vessel walls makes them fragile, so small retinal bleeds appear, sometimes with white centers.

18. High-altitude retinopathy
    Low oxygen and pressure changes at altitude make capillaries leaky, causing hemorrhages that may have a white core.

19. Severe hypoxia or carbon monoxide exposure
    Oxygen lack injures endothelium and alters clotting, so retinal hemorrhages with pale centers can appear.

20. Iatrogenic causes (chemotherapy, anticoagulants, antiplatelets)
    Drugs that lower platelets or thin the blood make retinal bleeding easier, sometimes with fibrin centers.

Symptoms

1. No symptoms at all
   Many Roth spots cause no vision change and are found by chance during an eye exam.

2. Blurred vision
   A spot near the center of sight can smudge or blur letters or faces, especially when reading.

3. A small dark spot or blind area (scotoma)
   If the bleed lies on the visual pathway, it can leave a tiny blank area in that part of vision.

4. Floaters
   Small clumps of blood or debris can drift in the gel of the eye and look like moving specks.

5. Distorted lines (metamorphopsia)
   If the macula is involved, straight lines may look bent or wavy.

6. Glare or light sensitivity
   Retinal irritation can make bright light uncomfortable.

7. Mild eye discomfort
   Roth spots themselves do not usually hurt, but other eye problems may cause ache or pressure.

8. Color vision seems dull
   Macular involvement may make colors look faded or less bright.

9. Poor night vision in the involved eye
   Low-light tasks may feel harder if the center of vision is affected.

10. Headache
    Headache may come from high blood pressure or infection that is also causing Roth spots.

11. Fever and chills
    This is a warning sign for infection like endocarditis, which can come with Roth spots.

12. Unexplained tiredness
    Anemia or sepsis can cause deep fatigue along with retinal signs.

13. Easy bruising or bleeding
    Low platelets or clotting problems may show as bruises, nosebleeds, or gum bleeding, with Roth spots in the eyes.

14. Unintentional weight loss or night sweats
    These can point to leukemia or chronic infection that also produces Roth spots.

15. Shortness of breath or chest pain
    These can signal endocarditis, anemia, or clots, and should prompt urgent care.

Diagnostic Tests

The total below is 20 tests across five groups: Physical Exam (4), Manual Tests (4), Lab/Pathology (6), Electrodiagnostic (2), Imaging (4).

A) Physical Exam

1. Vital signs (temperature, blood pressure, pulse, oxygen level)
   Fever can suggest infection. High blood pressure can point to hypertensive retinopathy. Low oxygen can signal hypoxia or lung/heart disease.

2. Cardiac exam for murmurs and heart failure signs
   A new heart murmur or heart failure signs can support infective endocarditis, a classic cause of Roth spots.

3. Skin and mucosal exam (petechiae, bruises, mouth and gums)
   Tiny red dots (petechiae), easy bruising, or gum bleeding suggest low platelets or clotting problems linked to retinal hemorrhages.

4. General exam for pallor, jaundice, lymph nodes, and neurologic checks
   Pallor points to anemia; jaundice may indicate liver disease; enlarged nodes can suggest leukemia or infection; neurologic deficits could reflect emboli.

B) Manual (Bedside/Ophthalmic) Tests

5. Visual acuity (Snellen chart)
   Measures sharpness of vision and tracks whether the Roth spot is affecting the macula or central sight.

6. Pupil exam for RAPD (swinging flashlight test)
   Checks for asymmetric optic pathway stress; severe retinal involvement can produce a relative afferent pupillary defect.

7. Confrontation visual fields or Amsler grid
   Screens for blind spots, scotomas, or distortion, especially if the hemorrhage lies in key retinal areas.

8. Direct ophthalmoscopy (in-office retinal look)
   Allows a close view of the retina to spot the red hemorrhage with a white center, confirm location, and see other vessel changes.

C) Lab and Pathological Tests

9. Complete blood count (CBC) with differential
   Looks for anemia, high or low white cells (infection or leukemia), and low platelets, all tied to Roth spots.

10. Peripheral blood smear
    A microscope look at blood to identify blast cells (leukemia), abnormal platelets, or other cell changes that explain bleeding.

11. Blood cultures (three sets before antibiotics if infection suspected)
    Aim to grow the bacteria causing endocarditis or sepsis, which directly supports the diagnosis behind the Roth spots.

12. Inflammatory markers (ESR and CRP)
    High levels support inflammation or infection, which often travels with retinal hemorrhages.

13. Coagulation profile (PT/INR, aPTT, fibrinogen, D-dimer)
    Finds clotting problems or DIC, which can cause retinal bleeding with white centers.

14. Glucose and HbA1c (± kidney/liver panel)
    Checks for diabetes control and organ function, because diabetes and systemic disease can drive retinal vessel damage.

D) Electrodiagnostic Tests

15. Visual evoked potential (VEP)
    Measures how signals travel from the retina to the brain. It helps if vision is worse than the exam suggests or if optic pathway stress is suspected.

16. Electroretinography (ERG)
    Measures retinal electrical responses to light. It helps judge whether vision loss is from widespread retinal dysfunction versus a focal hemorrhage.

E) Imaging Tests

17. Color fundus photography
    Takes high-resolution photos of the retina to document Roth spots, count them, and monitor healing over time.

18. Optical coherence tomography (OCT)
    Creates a microscopic cross-section of the retina to show exact layer of the hemorrhage, any macular edema, and the white core effect on structure.

19. Fluorescein angiography (FA)
    Injects a safe dye into the arm and tracks it through retinal vessels to reveal leaks, blockages, or capillary dropout that explain the spots.

20. Echocardiography (TTE or TEE) when endocarditis is suspected
    Ultrasound of the heart looks for valve infection (vegetations), which is a key systemic source of Roth spots.

Frequently asked questions

1. Do Roth spots mean I have an eye disease?
   No. Roth spots are a sign seen in the eye, usually pointing to a whole-body problem that needs evaluation.

2. Are they dangerous?
   The spots themselves are small. The cause can be serious (e.g., endocarditis or leukemia), which is why prompt work-up matters.

3. Will they make me blind?
   Roth spots rarely cause lasting vision loss by themselves. Vision issues usually improve as the underlying condition is treated.

4. How are they found?
   With a dilated eye exam using lenses and lights; your doctor may take fundus photographs or OCT images to document them.

5. What is the “white center”?
   It is clotted platelets and fibrin with cellular debris. It forms because a tiny vessel was blocked and the tissue in that spot was injured.

6. Are Roth spots only in endocarditis?
   No. They also appear with anemia, leukemia, diabetes, hypertension, vasculitis, HIV, sepsis, and trauma-related retinopathies.

7. How long do they last?
   Many fade over weeks to a few months after the cause is controlled. Your doctor will re-check the retina to confirm resolution.

8. Is there an eye drop for Roth spots?
   No. There is no specific eye drop to dissolve them. Treatment focuses on the systemic disease.

9. Can they come back?
   Yes, if the underlying risk returns or stays uncontrolled (e.g., ongoing infection, uncontrolled BP/glucose).

10. Do I need blood tests or heart scans?
