Choroidal hemangioma is a benign tumor that can impact vision due to fluid accumulation in the eye. Understanding this condition is crucial for early detection and effective management. Find a top optometrist or ophthalmologist near you to discuss your symptoms and get the care you need.
Choroidal hemangioma is a rare, benign tumor formed by abnormal blood vessels in the choroid, the vascular layer at the back of the eye. Although non-cancerous, it can cause fluid to build up and affect your vision. Understanding this condition can help you recognize symptoms early and explore the best ways to manage it and preserve your sight.
This section provides a complete overview of choroidal hemangioma, including its definition, different types, and how it can impact your eye's function and health.
The choroid is a thin, spongy layer of tissue rich with blood vessels, located between the retina and the sclera (the white of the eye). Its main job is to supply oxygen and nutrients to the outer retina. A hemangioma is a non-cancerous cluster of extra blood vessels that forms a benign tumor in this layer. It is usually congenital, meaning it is present from birth, but may not cause any issues until adulthood.
There are two main types of choroidal hemangioma. A circumscribed hemangioma is a localized, solitary lesion that is typically round or oval and found in one eye. A diffuse hemangioma involves a larger, more widespread area of the choroid and is characteristically associated with Sturge-Weber syndrome, a rare neurocutaneous disorder.
The abnormal blood vessels of a hemangioma can leak fluid under the retina, a condition known as serous retinal detachment. This fluid accumulation causes the retina to swell, which can impair vision. If the fluid remains for a long time, it may cause permanent damage to retinal layers and decrease visual acuity. Early diagnosis and monitoring are essential to prevent these complications.
Choroidal hemangiomas are very rare and are most often diagnosed in adults between the ages of 30 and 50. Circumscribed types usually occur sporadically with no gender preference. Diffuse forms, which are linked to syndromes, are more often identified in children.
Symptoms can vary widely depending on the size, location, and activity of the hemangioma. Recognizing the early signs can prompt a medical evaluation and reduce the risk of long-term vision loss.
Blurred or distorted vision, known as metamorphopsia, in one eye is a frequent early symptom. When fluid accumulates under the retina, it can cause straight lines to appear wavy, bent, or have missing areas. This can affect daily tasks like reading, driving, or recognizing faces.
Some patients may experience flashes of light (photopsia), shadows, or dark spots (scotomas) in their field of vision. In some cases, persistent retinal swelling can lead to more serious complications, such as retinal detachment or secondary glaucoma.
Symptoms often emerge in adulthood, even though the hemangioma itself is congenital. Vision changes typically occur when the tumor begins to leak fluid or grow, making regular eye exams critical even for individuals who have no symptoms.
Many individuals have a choroidal hemangioma that is discovered incidentally during a routine eye exam for glasses or an unrelated issue. This highlights the importance of comprehensive, regular eye care, as many of these tumors do not cause symptoms unless they affect the central part of the retina.
Choroidal hemangiomas develop from congenital malformations of the eye's vascular tissue, with certain risk factors specifically linked to rare genetic syndromes.
These growths form due to an abnormal development of blood vessels in the choroid before birth. The formation of a hemangioma is not influenced by your lifestyle, diet, or any form of injury. Most cases happen by chance and are considered sporadic.
Diffuse choroidal hemangiomas are primarily associated with Sturge-Weber syndrome. This rare congenital disorder is characterized by a port-wine stain birthmark on the face, neurological abnormalities like seizures, and eye problems, including glaucoma and hemangiomas.
Outside of its association with specific syndromes, there is currently no evidence that links choroidal hemangiomas to inherited genetic mutations or environmental exposures. Most cases occur in individuals with no family history of the condition.
A detailed examination using advanced imaging is crucial for an accurate diagnosis and for differentiating a hemangioma from other tumors inside the eye.
Your doctor will use several painless tests to visualize the hemangioma and check for fluid leakage.
During the exam, your pupils will be dilated with eye drops to give your doctor a clear and wide view of your retina and choroid. The ophthalmologist will look for a characteristic orange-red lesion. The imaging tests help confirm the diagnosis and ensure the growth is a benign hemangioma.
Finding a choroidal hemangioma early allows for prompt monitoring and intervention if needed. Treating fluid leakage quickly can prevent irreversible damage to the retina and help preserve your long-term vision. Many hemangiomas are found before they cause any symptoms at all.
It is essential for your doctor to distinguish a choroidal hemangioma from other masses that can form in the choroid. These include choroidal melanoma (a type of eye cancer), metastases (cancer that has spread from another part of the body), or other benign lesions. Imaging characteristics help make this distinction, as the treatment and prognosis differ markedly.
Management strategies focus on controlling symptoms like fluid leakage and preventing vision loss. The choice of treatment depends on the tumor's size, location, and whether it is causing symptoms.
If the hemangioma is not causing symptoms and there is no fluid leakage affecting your vision, your doctor will likely recommend observation. This involves regular checkups with imaging every 3 to 12 months to monitor for any changes. Many patients maintain good vision for years without needing any active treatment.
Photodynamic therapy (PDT) is the most common and preferred treatment for symptomatic hemangiomas. This procedure uses a light-activated drug and a low-power, or cold, laser to selectively close the abnormal, leaking blood vessels while sparing healthy retinal tissue. Conventional thermal lasers are used less often due to a higher risk of damaging the retina.
For larger or more aggressive tumors that do not respond to PDT, radiation therapy may be considered. This can include plaque brachytherapy or proton beam therapy. Injections of anti-VEGF drugs into the eye can help reduce retinal fluid but generally do not shrink the tumor itself and are often used as a secondary therapy. Surgery is extremely rare.
Research is ongoing to find new and better treatments for choroidal hemangioma. This includes novel drug therapies that target abnormal blood vessel growth and advanced laser modalities designed to minimize tissue damage. Discuss with your specialist if any clinical trials might be an option for you.

With proper care and regular follow-up appointments, most people with this condition can live full, active lives. Understanding eye care routines and helpful lifestyle adjustments can support your overall vision health.
To keep your eyes comfortable, it helps to wear UV-protective sunglasses to shield them from bright light. If your eyes feel dry or irritated, using lubricating eye drops can provide relief. It is also best to avoid rubbing your eyes, which can cause further irritation.
A healthy lifestyle supports your overall eye health. A diet rich in antioxidants, omega-3 fatty acids, and nutrients like lutein and zeaxanthin (found in leafy greens and colorful vegetables) helps nourish the retina. Regular exercise improves circulation, and staying informed about your condition helps you spot any changes early.
Connecting with support groups for rare eye diseases can provide emotional comfort and shared experiences. Educational materials from ophthalmologists and retina specialists can enhance your understanding and empower you. Most importantly, maintain open communication with your eye care team to ensure you receive optimal care.
Receiving a diagnosis of any rare condition can be stressful or cause anxiety. Do not hesitate to speak with a counselor or therapist if you feel you need help coping with the diagnosis and adjusting to life with this condition. Your mental well-being is an important part of your overall health.
If you experience any new or sudden changes in your vision, schedule an exam with an eye care provider promptly. Staying informed, following your doctor's recommendations, and attending all your scheduled appointments are the best steps you can take to protect your vision and maintain your quality of life.
