Philip Walsh - Digital Retinal Photography: The advanced way to examine the retina

What is a retina?

Retinas are often explained as being like the film in a camera. The retina receives light through the lens of the eye and converts that light into images that the brain interprets as our visual world.


Why do we need to keep an eye on the retina?

The retina is highly sensitive and prone to diseases such as diabetic retinopathy and glaucoma damage which can lead to significant vision loss or even blindness.

We recommend a regular eye examination every two years – even if you don’t think your prescription needs updating. Many eye diseases don’t exhibit early warning signals before they begin to damage your vision so by the time you notice you have a problem, your eyes could already be irreparably damaged. However, if we can catch eye diseases early, sometimes we can slow down or even stop vision impairment that would otherwise happen.

With the traditional method of ophthalmoscopy, the optometrist looks at your retina through a hand-held instrument. While this is a very effective way to examine the eye, the advantage of the state-of-the-art retinal photography is that photographs are stored permanently.

This means photos can be compared over time to help identify subtle changes in the eyes that could indicate the early stages of serious eyes diseases, such as glaucoma or macular degeneration.
