Choroidal Hemangioma
Understanding Choroidal Hemangioma
The choroid supplies blood and nutrients to the retina, so changes in this layer can influence how well you see. Early awareness helps prevent serious problems.
The choroid’s rich blood supply feeds the retina, allowing light signals to reach the brain. Any abnormal vessel growth here can disturb normal retinal function.
Circumscribed lesions appear as single, round spots, while diffuse lesions spread over a larger area. Diffuse hemangiomas are often linked to Sturge-Weber syndrome.
This condition is usually found in young to middle-aged adults and often affects only one eye. Regular exams help detect changes before vision is threatened.
Symptoms of Choroidal Hemangioma
Symptoms develop when the lesion disturbs the retina or causes fluid to collect under it. Recognizing these changes helps you seek prompt care.
Most people feel no pain or vision change at first, so the growth is often discovered during a routine eye exam.
As the hemangioma grows, it may trigger visual disturbances.
- Blurry vision
- Wavy or distorted vision
- Flashes of light
- Shadows or dark spots
Diagnostic Approaches
Accurate diagnosis guides treatment. Our retina specialists combine clinical observation with advanced imaging to learn the lesion’s size and activity.
By viewing the back of the eye, the doctor can see the orange-red lesion that signals a choroidal hemangioma.
This test creates cross-sectional images that show the dome-shaped, solid tumor and measure its depth.
Injected dye highlights blood flow, revealing early bright staining and late leakage typical of this vascular tumor.
This imaging method views deeper choroidal vessels, helping distinguish hemangioma from other tumors.
OCT provides detailed retinal cross sections, detecting subretinal fluid, retinal detachment, or pigment changes.
Causes of Choroidal Hemangioma
While the exact cause remains unclear, research links the growth to abnormal vessel development that begins early in life.
Most hemangiomas are present at birth yet stay unnoticed until adulthood when routine exams or vision changes reveal them.
Two patterns occur.
- Circumscribed: a single, isolated tumor unconnected to other health issues
- Diffuse: a widespread lesion often found with Sturge-Weber syndrome
Clusters of choroidal vessels grow irregularly, creating a raised reddish-orange area that can leak fluid and threaten vision.
Management and Treatment Approaches
Treatment depends on symptoms and lesion type. Many patients only need observation, while others benefit from targeted therapies.
If no vision loss occurs, regular visits allow the doctor to track changes and act quickly if new symptoms arise.
This light-activated drug and laser combo selectively destroys abnormal vessels while sparing healthy tissue, making it a preferred option for circumscribed lesions.
An infrared laser gently heats the lesion. Outcomes vary, so this method is chosen when other options are unsuitable.
Targeted radiation can reduce diffuse lesions or large fluid collections, improving or stabilizing vision.
Highly focused radiation treats challenging or recurrent cases, limiting damage to surrounding structures.
Injected medication blocks signals that encourage abnormal vessel growth, lowering the risk of complications like choroidal neovascularization.
Protecting Your Vision
Routine eye exams help detect choroidal hemangioma early and guide timely care. By staying alert to vision changes and following your eye doctor’s advice, you can safeguard sight and enjoy long-term ocular health.
Dr. Arnett has provided excellent medical attention for my retina eye surgery and has a very professional and positive bedside manner. I would highly recommend him.
