Choroidal Hemangioma

Choroidal hemangioma is a harmless, noncancerous growth made up of extra blood vessels in the choroid, the layer of blood‐rich tissue found between the retina (the light‐sensing layer at the back of your eye) and the white outer wall of the eye (sclera). These growths are born with you (congenital?) and do not spread to other parts of the body. When they press on the retina or leak fluid under it, they can blur vision or even detach the retina, but many never cause symptoms and are found by chance during an eye exam Specialty Vision.

Choroidal hemangioma is a benign? (noncancerous) vascular hamartoma—meaning it is made up of normal blood‐vessel tissue that has grown in an unorganized cluster—located in the choroid, the vascular layer beneath the retina. It appears as an orange-red or yellow-orange, dome-shaped mass under the retina and may leak fluid, causing retinal detachment or cystic retinal changes that blur vision. Many lesions remain stable and can simply be observed, but symptomatic tumors require treatment to preserve sight. New York Eye Cancer CenterRadiopaedia

Types of Choroidal Hemangioma

1. Circumscribed Choroidal Hemangioma (CCH)
   A single, well‐defined bump of extra blood vessels in the choroid. It usually appears later in adulthood and is not linked to any other health problems Radiopaedia.

2. Diffuse Choroidal Hemangioma (DCH)
   A broad, flat spread of extra vessels that often covers a large part of the choroid. This form nearly always occurs in people with Sturge–Weber syndrome, a rare condition marked by a port‐wine stain birthmark on the face and sometimes brain blood vessel changes Radiopaediasturge-weber.org.

Causes of Choroidal Hemangioma

Note: The exact trigger for these vessels to overgrow is not fully known. However, researchers point to congenital? (from birth) blood vessel malformation and certain genetic changes.

1. Congenital? Vascular Malformation
   Choroidal hemangiomas form before birth when blood vessels in the choroid grow too many branches or loops during eye development Specialty Vision.

2. Hamartomatous Growth
   They are hamartomas—benign? lumps made of extra, but otherwise normal, cells and tissues that grew too much in one spot Specialty Vision.

3. Somatic GNAQ Gene Mutation
   Many cases, especially those tied to Sturge–Weber syndrome, have a mutation in the GNAQ gene (changes in codon R183 or Q209) that affects blood vessel cell signals AAO Journal.

4. Somatic GNA11 Gene Mutation
   A similar mutation can occur in the GNA11 gene, affecting choroidal blood vessel growth in non‐syndromic cases AAO Journal.

5. Somatic Mosaicism
   Only some cells in the eye carry the mutation, leading to a patch of overgrown vessels rather than a whole‐eye change JAMA Network.

6. PHACE Syndrome
   A rare syndrome with large facial hemangiomas, heart defects, and sometimes eye blood vessel tumors including choroidal hemangiomas WebEye.

7. Embryologic Vascular Development Error
   During early pregnancy, the normal pruning of blood vessels in the eye may not occur, leaving extra vessels behind Specialty Vision.

8. Local Hypoxia (Low Oxygen)
   Low oxygen levels in certain areas of the developing eye may spur excess vessel growth in the choroid Specialty Vision.

9. VEGF Overexpression
   Too much vascular endothelial growth factor (VEGF), a protein that tells vessels to grow, may play a role even before birth PMC.

10. VEGFR Signaling Dysregulation
    Faulty receptors for VEGF on choroidal cells may amplify growth signals in the vessel walls PMC.

11. Wnt Pathway Alterations
    Changes in the Wnt signaling pathway, important in blood vessel formation, may underlie some hemangiomas Specialty Vision.

12. TIE2 Receptor Mutations
    Rare mutations in the TIE2 receptor gene, seen in other vascular malformations, could contribute (though direct evidence is limited) Specialty Vision.

13. RASA1 Gene Variants
    Variants in RASA1, linked to other capillary malformations, have been observed in scattered case reports Specialty Vision.

14. Somatic Mosaicism in Other Angiogenesis Genes
    Mosaic mutations in genes that regulate vessel growth (e.g., PI3K‐AKT pathway) may affect local choroidal vessels Specialty Vision.

15. Inflammatory Cytokine Influence
    infection?, or irritation, often causing pain?, swelling?, heat, or redness. সহজ বাংলা: শরীরের প্রদাহ; ব্যথা, ফোলা বা লালভাব হতে পারে।" data-rx-term="inflammation" data-rx-definition="Inflammation is the body’s response to injury, infection, or irritation, often causing pain, swelling, heat, or redness. সহজ বাংলা: শরীরের প্রদাহ; ব্যথা, ফোলা বা লালভাব হতে পারে।">Inflammation? in utero could raise local cytokines, nudging vessels to multiply Specialty Vision.

16. Placental Insufficiency
    If the placenta underperforms early in pregnancy, fetal tissues—including the eye—may trigger extra vessel growth to compensate Specialty Vision.

17. Maternal Teratogen Exposure
    Very rarely, exposure to certain drugs or toxins during pregnancy is theorized to disturb normal vessel pruning Specialty Vision.

18. Radiation Exposure
    High‐dose radiation in utero can disrupt normal blood vessel development, though this is exceedingly rare Specialty Vision.

19. Intrauterine Infections
    Maternal infections like rubella may interfere with vessel maturation, possibly leading to vascular hamartomas in the eye Specialty Vision.

20. Unknown Genetic/Environmental Factors
    Many cases arise without any clear risk factor, pointing to undiscovered genes or subtle environmental influences Specialty Vision.

Symptoms of Choroidal Hemangioma

Most choroidal hemangiomas do not cause symptoms. When they do, it usually means the growth is pressing on or leaking fluid under the retina.
