Spotting and Managing Choroidal Hemangioma
Understanding Your Choroidal Hemangioma Diagnosis
This section explains what a choroidal hemangioma is, how common it is, and why early recognition matters.
Choroidal hemangiomas affect about 0.0005 percent of the general population, which means only a few people in a large city are likely to have one.
The choroid is the layer of blood vessels that supplies the retina with oxygen and nutrients. Any growth in this layer can disturb normal retinal function and blur vision.
Two main types exist. Circumscribed lesions appear as a single round spot in one eye, while diffuse lesions cover a wider area and are often linked to Sturge-Weber syndrome.
Because the tumor can grow without symptoms, regular eye exams are vital. Early detection lets doctors watch the lesion or begin treatment before vision loss occurs.
Recognizing Choroidal Hemangioma Symptoms
Symptoms often change over time. Knowing what to look for helps you seek timely care.
Fluid from the tumor can collect under the retina, causing a shallow detachment that interferes with normal retinal signaling.
Most people feel no pain or vision change in the early stage, so the growth is usually found during a routine eye exam.
As the lesion progresses, you may notice blurry or wavy vision, flashes of light, or shadows in part of your visual field.
How We Diagnose Choroidal Hemangioma
Accurate diagnosis combines careful examination with imaging tests that reveal the tumor’s size, location, and activity.
Using a special lens and light, we inspect the back of the eye for an orange-red, dome-shaped lesion.
B-scan ultrasound provides cross-sectional images that confirm the solid, dome-shaped structure and measure its dimensions.
This test tracks dye flow through retinal blood vessels, showing early bright filling and late leakage that suggest active vascular tissue.
ICG outlines deeper choroidal vessels, helping us tell a hemangioma from other tumors.
OCT captures high-resolution cross sections of the retina, revealing fluid buildup, retinal detachment, or pigment changes caused by the lesion.
What Causes Choroidal Hemangioma
Although the exact cause is not fully understood, several factors appear to play a role.
Most hemangiomas are present from birth but stay hidden until adulthood, when they may be spotted during an eye exam.
Circumscribed tumors occur alone, while diffuse tumors often appear with Sturge-Weber syndrome, which can affect the skin and brain as well.
Clusters of choroidal vessels grow in an unusual pattern, creating a raised area that may leak fluid and disturb vision.
Treatment Options for Choroidal Hemangioma
Treatment depends on tumor type, size, and whether vision is threatened. Some patients need only observation, while others benefit from targeted therapies.
If the lesion is small and causes no symptoms, regular monitoring may be all that is required.
A light-activated drug and focused laser destroy abnormal vessels while sparing healthy tissue, making this a preferred option for many circumscribed tumors.
An infrared laser gently heats the lesion. Results can vary, so this method is usually reserved for selected cases.
Targeted radiation can shrink diffuse tumors or those with widespread fluid, easing symptoms and protecting vision.
This highly focused radiation is useful for challenging or recurrent lesions because it minimizes exposure to surrounding tissue.
Injection of medication that blocks vascular endothelial growth factor can reduce leakage and secondary complications when used with other treatments.
The Importance of Early Eye Evaluations
Any sudden change in eyesight should prompt a prompt eye exam. Early care helps prevent lasting damage and supports the best possible outcome.

I always feel very confident in Dr. Soll's Evaluaciones and Recommendations. Dr. Rho also gave also gave me a thorough retina exam
Rose Curley
I was given an emergency appointment with Dr Rho. He looked in my eyes and saw a hole in my retina. I am so thankful to Dr. Rho and his team for making me feel comfortable and at ease.
