Amsler Grid

The Amsler grid is a useful tool to detect vision problems resulting from damage to the macula (the central part of the retina).

Report any irregularity to your eye care professional immediately.

The grid does not replace having your macula tested by an eye care professional, particularly if you are over 50 yrs old or have any risk factors for macular degeneration.

Amsler Grid

How to do it

  1. Cover one eye, then focus on the dot in the centre.
  2. Do any of the lines look wavy, blurred or distorted?
  3. Are there any missing areas or dark areas in the grid?
  4. Don't forget to test
    both eyes.

Ophthalmologist at Hamilton Eye Clinic and Waikato Hospital, Hamilton

David graduated from Auckland Medical School in 1981 and undertook ophthalmology training in Auckland and Hamilton to become a Fellow of the Royal Australian and New Zealand College of Ophthalmologists in 1986. David undertook sub-specialty fellowship training in medical and surgical retina at Bristol Eye Hospital, England (1989-1991).

David returned to Hamilton in 1991 as a medical and surgical retinal specialist at Waikato Hospital and Hamilton Eye Clinic. He has a particular interest in the rapidly evolving treatments and prevention strategies for macular degeneration.  Research is of particular interest and David is very actively involved with two international biomedical companies aiming to develop new treatments for macular degeneration - early research with a drug for treating wet macular degeneration in combination with the current drugs (Avastin, Lucentis or Eylea), and research into retinal applications for a cell-based intraocular implant that has already commenced clinical trials in New Zealand for neurodegenerative brain disease. In 2013 David joined an international group of retinal laser specialists and now uses a novel nanosecond macula laser in New Zealand for the treatment of dry macular degeneration. David is also working with automated diabetic retinopathy photographic screening software being developed at Waikato University.

David is a medical advisory board member for Macular Degeneration New Zealand, Retina New Zealand and several international pharmaceutical and biomedical companies.

More common than you think

Age related Macular Degeneration is the most common cause of blindness

You need to know!

Of those most at risk (50+) 67% have heard of MD and only 48% understand that it is an eye disorder. *Galaxy Poll March 2014

People with a family history of MD have a 50% chance of inheriting the genetic predisposition of developing MD.

What if I don't have treatment?

Untreated, the majority of people with wet MD become functionally blind within 2 years
