What Is Juxtapapillary Choroidal Neovascularization?

Juxtapapillary choroidal neovascularization (CNV) involves the growth of abnormal blood vessels near the optic nerve head. These vessels leak fluid or blood, distorting central or paracentral vision. The condition appears in high myopia, inflammatory disorders, or age-related degeneration. People may notice waviness, dim areas, or sudden blur. Imaging helps define the lesion's location and activity.

Causes of Juxtapapillary CNV

Degeneration of the choroid in high myopia is a common cause. Inflammatory conditions such as multifocal choroiditis can also trigger vessel growth. Aging weakens Bruch's membrane, allowing new vessels to form. Trauma is a less common contributor. Identifying the cause shapes treatment choices.

Symptoms of Juxtapapillary CNV

People may notice distortion when looking at straight lines. Blurred patches near central vision often develop. Colors can seem dull or washed out. Sudden bleeding may cause dark spots. Symptoms depend on lesion activity.

How It Is Diagnosed

OCT detects fluid or pigment epithelial detachment. Fluorescein angiography highlights leakage from new vessels. Fundus photography documents lesion borders. Visual acuity tests track functional change. Imaging guides treatment planning.

Treatment for Juxtapapillary CNV

Injections of anti-VEGF medication reduce leakage and shrink abnormal vessels. Photodynamic therapy is used in selected cases. Monitoring detects recurrence. Long-term follow-up is important in chronic conditions. Many people respond well to early treatment.

Frequently Asked Questions About Juxtapapillary CNV

Is vision loss permanent?

Some vision may recover with treatment.

Can this recur?

Yes, CNV can reactivate.

Does this affect both eyes?

It depends on the underlying condition.

When should I seek care?

Seek care for new distortion or sudden blur.
