Understanding neovascular age-related macular degeneration

Many people with AMD do not immediately recognise the symptoms, mistaking them for normal signs of ageing. This leads to more severe conditions such as neovascular AMD (nAMD) and geographic atrophy.3,4

In nAMD, new and abnormal blood vessels grow uncontrollably under the macula, causing swelling, bleeding and/or fibrosis.5

nAMD affects 20 million people worldwide.1,6

The number of people with AMD globally is expected to reach 288 million by 2040.2

nAMD is the leading cause of vision loss in people over the age of 60.2

Age

Obesity

Genetics

Family history of AMD

Gender

Women are at a higher risk

Race

More common among Caucasians

Smoking

Smokers are 2-5 times more likely to be impacted

Blurred vision

Difficulty seeing at distance or doing detailed work

Blind spots developing in the line of sight

Difficulty distinguishing between colours

Edges and straight lines appearing wavy

Impaired vision can impact:9,10,11

• The ability to carry out everyday tasks

• The ability to work

• The ability to lead an active social life

• Quality of life, with increased social isolation, depression and anxiety disorders

nAMD may impact the ability to see or recognise faces, read, drive or watch TV.1,9

Getting an annual eye test is the best way to detect any changes in vision. A dilated retinal examination will help to diagnose any retinal diseases. If you’d like more information on nAMD or other retinal diseases, talk to your optician or visit
