WHAT IS ARMD?
It is an abbreviation for a disorder called Age Related Macular Degeneration. ARMD is a degenerative disease, which affects macula, a spot on the center of retina where sharpest image of the eye is formed. Macula is the most sensitive part of retina responsible for central vision.
In some cases ARMD advances so slowly that people notice little change in their vision. In others it progresses faster and may lead to loss of vision in both eyes. It is one of the leading causes of loss of vision in adults over 60 years of age.
WHAT ARE THE SYMPTOMS OF ARMD?
- ARMD causes no pain
- Loss of central vision: This may be gradual for those with dry ARMD. Patients with wet ARMD may lose vision suddenly
- Straight lines in your field of vision like electric / telephone poles, the sides of building appearing to be wavy
- Words in books, newspapers magazines appear blurry
- Dark / empty spaces may block the vision

WHAT IS TREATMENT OF ARMD?
https://www.instagram.com/eyenu.hospital/There is no proven medical therapy for dry type. However, The National Eye Institute’s Age Related Eye Disease Study (AREDS) found that taking a high dose formulation of anti-oxidants and zinc may reduce the risk of advanced ARMD.
Early diagnosis is critical for successful treatment of wet type. Recently photodynamic therapy, Intravitreal steroids and AntiVEGF drugs like, avastin, Macugen, Lucentis has proven to be of some help in stopping abnormal blood vessels growth in some patients with wet ARMD. Photodynamic therapy with verteporphyn along with antiVEGF drugs brings the disease under control. Laser photocoagulation can also be done in some cases.
