Age Related Macular Degeneration (AMD) 

Overview

Macula is the central part of the sensory layer in the back of the eye (retina). In Age Related Macular Degeneration (AMD) this area becomes affected and this causes a deterioration of central vision and problems with reading, detecting faces and any other activities that require detailed vision.

Stages of Macular Degeneration 

Early Stage

This stage usually happens in patients older than 50 and caused by gradual built up of waste material (Drusen) beneath the retina. Most of patients at this stage don't have any symptoms. There is no treatment available for this condition, however having a healthy diet, avoiding smoking and a good control of systemic conditions like hypertension decreases the risk of progression of the disease to more advanced forms.

Late Stage

At this stage central vision become impaired and can be subdivided to Dry type (Atrophic) or Wet type 

(Neovascular) Macular Degeneration.

Dry Type: Atrophy (loss) of sensitive nerves in the macula happens leading to a gradual loss of central vision. There is no proven treatment available for this condition.

Wet Type: Abnormal fragile vessels grow beneath and in the retina which leak fluid and blood. It usually causes a rapid decrease in central vision.

Advance AMD

The main treatment for advanced Wet AMD is injecting a medicine directly into the eye. It is done in the clinic using a sterile technique and gives you a good chance of maintaining or improving your vision.
