Intraocular Vascular Tumors

An intraocular vascular tumor is an abnormal, benign or malignant growth of blood‐vessel cells inside the eye. These tumors arise from the vascular (blood vessel) tissue of the eye’s choroid, retina, or ciliary body. Although rare, they can cause vision problems or even threaten the eye if untreated. In very simple English, think of these tumors as small lumps of extra blood‐vessel cells growing where they shouldn’t, inside the eye.

Types of Intraocular Vascular Tumors

1. Choroidal Hemangioma
   A benign (non‐cancerous) mass of blood vessels in the choroid layer under the retina. It often looks like an orange or red bump when the eye doctor shines a light inside.

2. Retinal Capillary Hemangioma
   Small clumps of tiny blood vessels (capillaries) on the retina surface. These may leak fluid and cause swelling in the retina nearby.

3. Cavernous Hemangioma of the Retina
   A cluster of larger, balloon‐like blood‐vessel spaces in the retina. These usually do not leak but can press on surrounding tissues.

4. Vasoproliferative Tumor of the Retina
   A pinkish, raised lesion on the peripheral retina made of both blood vessels and scar tissue cells.

5. Racemose Hemangioma (Wyburn-Mason Syndrome)
   An arteriovenous malformation in the retina where arteries directly connect to veins without capillaries, often associated with brain vessel malformations.

6. Retinal Angioma (Von Hippel-Lindau)
   Multiple capillary hemangiomas in the retina, part of a genetic condition that also causes kidney cysts and tumors elsewhere.

7. Choroidal Vasoproliferative Tumor
   Similar to retinal vasoproliferative tumors but located under the retina in the choroid, presenting as a pinkish mass.

8. Ocular Ischemic Syndrome-Related Neovascularization
   New, abnormal vessel growth on the iris or retina due to low oxygen from blocked arteries—though technically a proliferative vascular response rather than a true tumor.

9. Coats’ Disease
   Abnormal, leaky blood vessels in the retina, often in young boys, leading to fluid buildup and sometimes retinal detachment.

10. Retinoblastoma with Vascular Components
    A malignant tumor of childhood that can show blood‐vessel proliferation inside the mass.

11. Retinal vasoproliferative tumor (idiopathic or secondary to inflammation)

12. Diffuse choroidal hemangioma (associated with Sturge–Weber syndrome)

13. Circumscribed choroidal hemangioma (isolated, usually posterior pole)

14. Retinal arteriovenous malformation (racemose hemangioma)

(Note: While retinoblastoma is cancerous, most intraocular vascular tumors are benign.)

Common Causes & Risk Factors

Each cause below explains why vascular tumors might form in the eye.

1. Genetic Mutations
   Changes in specific genes (like VHL gene in Von Hippel-Lindau) can cause excess vessel growth.

2. Congenital Malformations
   Some babies are born with weak spots in blood vessel walls that later balloon into hemangiomas.

3. Chronic Inflammation
   Long‐term eye inflammation (uveitis) can stimulate new vessel growth that forms a tumor.

4. Ocular Trauma
   Injury to the eye may trigger repair processes gone awry, leading to abnormal vessel proliferation.

5. Radiation Exposure
   Past radiation therapy to the head/eye area can damage vessels, prompting tumors years later.

6. Systemic Hypertension
   High blood pressure stresses vessel walls and may predispose to vascular malformations in the eye.

7. Cardiovascular Disease
   Poor blood flow patterns can create areas of vessel weakness.

8. Diabetes Mellitus
   Diabetes damages capillaries, sometimes causing abnormal vessel growth in the retina.

9. Hyperlipidemia
   High blood fats can clog small vessels and change blood‐vessel behavior.

10. Hypoxia (Low Oxygen)
    Low oxygen in retinal tissues (from blocked arteries) triggers new vessel growth.

11. Hormonal Changes
    Pregnancy or puberty can alter vessel‐growth signals, occasionally revealing hidden tumors.

12. Infection
    Certain infections (e.g., toxoplasmosis) cause inflammation and can lead to vascular proliferation.

13. Autoimmune Disorders
    Immune attack on eye tissues can indirectly promote vessel overgrowth.

14. Surgical Procedures
    Eye surgeries may leave scars that attract new vessels into lumps.

15. Age-Related Changes
    Aging alters vessel wall structure, sometimes allowing small hemangiomas to form.

16. Genetic Syndromes
    PHACES syndrome and Sturge-Weber syndrome include facial and ocular hemangiomas.

17. Tumor-Secreted Factors
    Nearby tumors can release growth factors (VEGF) that encourage vessel tumors.

18. Radiation Retinopathy
    After radiation treatment, damaged vessels can proliferate abnormally.

19. Retinal Vein Occlusion
    Blocked veins in the retina cause backup of blood, prompting vessel tumor formation.

20. Unknown/Idiopathic
    In many cases, no clear cause is found.

Symptoms

Intraocular vascular tumors often cause no symptoms at first. As they grow or leak fluid, these signs can appear:

1. Blurred Vision
   Leaking fluid or swelling near the macula blurs central sight.

2. Floaters
   Flashes or spots float across vision if bleeding occurs.

3. Photopsia (Flashes of Light)
   Irritation of the retina by the mass can trigger light flashes.

4. Visual Field Loss
   Tumors in peripheral retina cause blind spots at the edges.

5. Metamorphopsia
   Straight lines look wavy when the macula is involved.

6. Red Reflex Change
   On simple flashlight exam, the normal red glow of the eye may turn orange or dark.

7. Eye Pain or Discomfort
   Larger tumors can press on structures, causing aching.

8. Eye Redness
   Inflammatory response around the tumor may redden the white of the eye.

9. Increased Intraocular Pressure (Glaucoma)
   Tumors can block fluid drainage, raising eye pressure.

10. Hazy Cornea
    High pressure or inflammation can cloud the cornea surface.

11. Iris Neovascularization
    New vessels grow on the iris surface, visible on slit‐lamp exam.

12. Floaters from Vitreous Hemorrhage
    Bleeding into the jelly (vitreous) causes dark spots drifting in vision.

13. Double Vision
    Large tumors may push the eye out of alignment with the other eye.

14. Photophobia (Light Sensitivity)
    Inflammation or iris vessels can make bright light painful.

15. Sudden Vision Loss
    Massive bleeding or detachment can abruptly block vision.

Diagnostic Tests

When an eye doctor suspects an intraocular vascular tumor, they use several tests grouped by type:

A. Physical Exam Tests

1. Visual Acuity
   Reading letters on a chart checks how clear vision is.

2. Pupil Exam
   Shining light into each eye watches for normal constriction.

3. Intraocular Pressure Measurement
   A gentle puff of air or tonometer checks eye pressure.

4. External Inspection
   Checking eyelids, conjunctiva for redness or swelling.

B. Manual Examination

5. Slit-Lamp Biomicroscopy
   A special microscope and light examine the front of the eye and iris vessels.

6. Indirect Ophthalmoscopy
   Using a head‐mounted lens and light to view the retina and choroid.

7. Gonioscopy
   A contact lens lets the doctor see the angle where fluid drains (to check for vessel growth).

8. Fundus Photography
   Color photos document the tumor’s size and appearance over time.

C. Laboratory & Pathological Tests

9. Complete Blood Count (CBC)
   Checks for blood disorders that might cause eye vessel changes.

10. Serum VEGF Levels
    Measures vascular growth factor that tumors release.

11. Genetic Testing

12. Biopsy & Histopathology
    Rarely done; a tiny sample of the tumor is examined under a microscope to confirm type.

D. Electrodiagnostic Tests

13. Electroretinography (ERG)
    Measures electrical responses of retinal cells to light, to see if the tumor affects function.

14. Electro-oculography (EOG)
    Tests the electrical signal between front and back of the eye to assess general eye health.

15. Visual Evoked Potential (VEP)
    Records brainwaves generated when retina sends signals, checking full visual pathway.

E. Imaging Tests

    High‐resolution cross-section pictures of retina layers to show fluid or tumor under the retina.

17. B-Scan Ultrasonography
    Sound waves form an image of the tumor’s size and internal reflectivity.

18. Fluorescein Angiography
    A dye injected in the arm shows leaking vessels on sequential eye photos.
