A Clear Guide to Polypoidal Choroidal Vasculopathy (PCV)
What Is Polypoidal Choroidal Vasculopathy?
PCV is a retinal condition marked by abnormal, branching blood vessels beneath the retina that can leak fluid or bleed. It affects about 0.2 percent of the general population and is often mistaken for age-related macular degeneration.
In PCV, blood vessels in the choroid become dilated and form small, polyp-like bulges that may leak or bleed into surrounding retinal layers.
While both conditions involve the macula, PCV requires different imaging techniques and may respond better to combination therapy than typical macular degeneration.
Prompt diagnosis allows for timely treatment, reducing the risk of vision loss and limiting complications such as fluid buildup or scarring.
Demographics and Causes of PCV
PCV appears most often in adults between ages 50 and 65, with higher rates in Asian populations and lower rates in Caucasian groups.
Men and women of diverse ethnic backgrounds can develop PCV. Studies show it affects up to 54 percent of patients in Japan who were first thought to have macular degeneration, compared with 4 to 9.8 percent in many Caucasian populations.
The exact trigger is not fully understood, yet abnormal changes in choroidal blood vessels play a key role.
- Vessels dilate and form polyp-like outpouchings
- Weakened walls allow fluid or blood to leak beneath the retina
- Leakage disrupts the retinal pigment epithelium and may blur vision
Common Signs and Symptoms
PCV often begins subtly, so recognizing early changes helps protect sight.
Patients may notice one or more of these warning signs:
- Blurred or dim vision in one eye
- Central or paracentral scotoma, a dark or blurry spot near central vision
- Distortion or waviness in straight lines, called metamorphopsia
- Fluctuating vision or sudden shifts in brightness or contrast
During a detailed retinal evaluation, a specialist may observe:
- Orange-red, polyp-like lesions sprouting from the choroid
- Serous or hemorrhagic retinal detachments
- Hard exudates from leaking blood vessels
- Occasionally, vitreous hemorrhage causing sudden vision loss
Monitoring Your PCV Progress
Managing PCV is a long-term process that relies on regular follow-up visits and advanced imaging.
Optical Coherence Tomography and Indocyanine Green Angiography help detect fluid buildup, new bleeding, or early scarring so treatment can be adjusted promptly.
Effective Treatments for PCV
Treatment aims to control abnormal vessels and fluid, preserving central vision.
The EVEREST study showed that photodynamic therapy combined with anti-VEGF injections achieves higher rates of complete polyp closure than injections alone.
- PDT seals abnormal vessels with a light-activated drug
- Anti-VEGF medicine blocks signals that cause new vessel growth
- Used together, these methods improve polyp regression and visual stability
The LAPTOP and PLANET trials found that anti-VEGF injections alone can stabilize vision and reduce retinal fluid, though complete polyp resolution is less common.
PDT selectively targets abnormal choroidal vessels and can shrink or close polyp-like lesions, especially when paired with injections.
In rare situations where lesions are small and away from central vision, traditional laser therapy may seal leaking vessels.
Possible Complications of PCV
Without proper care, PCV can lead to several sight-threatening issues.
Subretinal fibrosis may develop after bleeding episodes, causing pigment epithelial changes and risking long-term vision decline.
Repeated bleeding under the retina can create ongoing visual disturbances and scarring.
Fluid leakage from abnormal vessels distorts normal retinal architecture and may blur central vision.
Scar tissue forms as the retina heals, potentially affecting retinal function when the macula is involved.

Dr. Rho is the best retina specialist in the world he saved my eye sight very professional
Karen Hawkins
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.
