Macular Degeneration

What is Macular Degeneration?

  • Age-related macular degeneration (AMD) is a problem with the part of the retina responsible for central vision (macula).
  • It is the leading cause of blindness in Australians over the age of 60.
  • Age-related changes and damage accumulate in the macula and causes progressive loss of central vision.
  • Symptoms of AMD may include blurry vision, distortion, problems with depth perception and loss of vision.
  • There are two types of AMD: Dry AMD and Wet AMD


  • This is the more common type of AMD and is characterised by the deposition of waste material under the retina, known as “drusen”.
  • Patients with Dry AMD may experience gradual reduction in central vision over many months to years.
  • There is currently no treatment for Dry AMD, however, a specific group of patients may benefit from taking AREDS2 vitamin supplementation.
  • Please seek specialist advise in order to determine if you will benefit from these supplements.


  • While being the less common type of AMD, it is a much more serious form to have.
  • Wet AMD occurs when new, abnormal blood vessels grow under the retina and cause leakage or bleeding, which can lead to scarring.
  • Symptoms include a more rapid and severe loss of central vision or visual distortion.
  • It is crucial that Wet AMD be detected at an early stage and treatment initiated as soon as possible.
  • The treatment is in the form of regular injections of medications into the eye, known as intravitreal injection therapy.
  • If caught early, Wet AMD responds very well to treatment but each patient requires a personalised maintenance plan tailored to their specific disease in order to avoid relapse.
  • Dr Sia has extensive experience in treating AMD and will provide an individualised approach to your treatment.

Intravitreal Injection

  • This procedure involves numbing the eye with anaesthetic drops, followed by antiseptic drops to sterilise the surface of the eye.
  • The medication is then delivered into the eye using a very fine needle.
