Treatment: 

Urgent Referral to ophthalmology for further treatment. This typically involves using drugs (Lucentis, Avastin, EyeLea) that stop the tiny blood vessels that have developed in the back of the eye from leaking or bleeding any further. It also helps to prevent new blood vessels from forming.


While the injection of these medications into the eye will work to slow or stop the loss of vision, they cannot bring back any vision that has been lost. 


About 10% of patients with dry ARMD will progress to the wet form of AMD.


A person with wet ARMD will typically have vision much worse then compared to someone with the dry form of ARMD. With the above example there is a major difference with how this person sees from their right eye (20/200, wet ARMD) compared to their left eye (20/40, dry ARMD).


Who is most at risk?

  • Smoking

  • Obesity

  • Family history

  • Cardiovascular disease

These four factors increase a persons risk of developing wet macular degeneration.
