UNDERSTANDING mCNV

Jan 6, 2017



Myopic choroidal neovascularization (mCNV) is a common, vision-threatening complication of pathological myopia, or severe nearsightedness.1 If left untreated, mCNV can lead to legal blindness.1

A Vision-
Threatening
Condition

mCNV is a severe, vision-threatening complication of pathological myopia.2

  • 9.6 MILLION

    ADULTS HAVE PATHOLOGICAL MYOPIA IN THE U.S.3

  • 41,000+

    OF THOSE HAVE mCNV3

~30% of people with mCNV in one eye will develop mCNV in their other eye within 8 years2

Effect On Vision

When untreated, 89% of people with mCNV have a visual acuity of 20/200 or worse (legal blindness) after 5 years.4 Healthy vision is 20/20

How Does mCNV Affect Your Eye?1

As a result of severe nearsightedness, new, abnormal blood vessels grow directly into the retina

These vessels can break and leak blood or fluid into the retina. This leakage can cause irreversible central vision loss

Signs and Symptoms1

A RAPID PROGRESSION OF CENTRAL VISION LOSS

(within a day or a few weeks)

BLURRED VISION
DISTORTION OF OBJECTS AND LINES
DIFFICULTY DISTINGUISHING BETWEEN COLORS

mCNV Risk Factors

GENDER

Women at a 2x higher risk3

AGE

Most commonly, people between 45-64 years old3

RACE

More common in people of East Asian descent1

PEOPLE WHO HAVE PATHOLOGICAL MYOPIA1

Annual Dilated
Eye Exam

Visit an eye doctor for a regular dilated eye exam. It’s the best way to help detect changes in vision
