What Is Juxtapapillary CNV (Choroidal Neovascularization)?

Juxtapapillary choroidal neovascularization occurs when abnormal blood vessels form near the optic nerve and extend beneath the retina. These vessels leak fluid or blood, leading to distortion or blurred vision. The condition develops from inflammation, myopia, or degenerative changes in the surrounding tissue. Symptoms vary depending on how close the membrane is to central vision. Imaging helps detect early activity before major vision loss develops.

Causes of Juxtapapillary CNV

Inflammation is a frequent trigger. High myopia creates structural weakness. Age-related changes can influence vessel growth. Certain hereditary disorders contribute. Identifying the cause helps guide care.

Symptoms of CNV Near the Disc

Distortion of straight lines is common. Central or paracentral blur may appear. Colors may seem washed out. Some cases remain unnoticed until bleeding occurs. Symptoms depend on membrane size.

How It Is Diagnosed

OCT detects fluid or elevation. Angiography maps abnormal vessels. Retinal exam identifies subtle borders. Vision tests help track functional loss. Imaging confirms activity.

Treatment for Juxtapapillary CNV

Anti-VEGF injections reduce leakage. Laser may be used in selected patterns. Observation is possible when inactive. Follow-up detects recurrence. Treatment depends on activity level.

Frequently Asked Questions About Juxtapapillary CNV

Does it cause permanent loss?

Early treatment reduces long-term damage.

Can it recur?

Recurrence is possible with active disease.

Is it painful?

No, pain is uncommon.

When should I seek care?

Seek care for new distortion or central blur.
