Looking deeper into your eye, the camera never lies.

Cannon OER CR6 Optic Nerve reference photos

There is no better way to examine the health of your eyes than the microscopes we always use. With the correct lenses and often using pupil dilating eyedrops we can examine the inside of your eye in unparalleled detail. The problem is recording what we see.

The early diagnosis of most eye disease results in better treatment outcomes and this requires comparing the health and structure of the eye from one visit to the next. If we only used our microscopes we’d have rely completely on descriptions and estimations of the structure and condition of your eye. Reading these descriptions a year later can leave some room for error.

If you’ve had an eye test recently we have probably taken images of your eye. This is so that we can reference our descriptions with the images and make a far more accurate detailed decision about whether things have changed. Better for us and more importantly, better for you!

This journey started using 35mm films. At the time we only saw the photo’s about a week after they were taken and many had to be reprocessed to get the exposure right. Cumbersome! Digital photography changed all that and for the last 15 years we’ve used a Canon EOR CR6 system, detailing up to 45 degrees of field in any one image with stunning detail.

Confocal scanners are the newest generation of imagers allowing us to record more than 160 degrees of retinal area beautifully, capturing not only the detail but the retinal blood vessels over a very wide retinal area in true colour. This device also reliably records the texture of the subretinal layers that are so unique in all of us. This device allows us to take infra red images too that record deep into your retinal layers.

Sometimes a top down image just isn’t good enough and we have to know what is happening at the level of the individual nerves.

High Definition Optical Coherence Tomographers allow us to capture and accurately record the actual layers of the retina and the microscopic variations and disturbances within them. State of the art screening for glaucoma and macular degeneration involve these machines. Many other retinal pathologies are diagnosed and motored using this platform and it looks very likely that the earliest diagnosis of dementia and other neurodegenerations will involve these machines because some of the earliest measurable signs are in the retina. This makes a good case for scans on everybody to allow for tracking change over time. We prefer the Zeiss Cirrus for its accuracy and reliability.

HD-OCT scan through the macula in a normal healthy eye

If we don’t need to do an HD-OCT scan at your next eye exam and you would like this on your file, please just ask, it is a good idea.
