Optomap is a highly advanced device that takes a detailed and comprehensive image of the retina at the back of the eye. It takes the widest image possible compared to all other devices in the world. It’s completely safe, painless and takes seconds to get an image. It was designed by an engineer who’s son lost his sight because of a tear in the retina that couldn’t have been detected using existing technology, He founded Optos the company that make the device.
The machine has a special safe, low powered laser combined with an accurately curved mirror to look through your pupil and scan your retina to create a detailed image.
The retina is an extremely thin layer, inside the back of the eye, that senses the light entering your eye to form an image. It acts very similarly to the film or sensor in a camera in the way it captures the light. In many retinal diseases, you may not notice any changes until it is too late. An eye test should always include an examination of the retina to check for problems and risks of blindness. The retina is the only place in your body where we can see live blood vessels, so many conditions that affect the blood supply, such as diabetes and high blood pressure may be seen in the retina (see more below)
The entire process takes about 5 minutes. Each Optomap scan only takes a few seconds. We take a couple of different scans for each eye to ensure we have a detailed and useful image.
The beauty of the optomap is that, in most cases, dilation of the pupils is not necessary. Unlike existing technology and examination techniques, we can get a good image if you have small pupils. This means no stinging eye drops or blurry vision for a few hours.
Everyone should have a scan at their routine sight test. We can examine over 4 times as much of the retina compared to all other techniques. Without it we would never know if there are potential problems to address if we only examine your eyes with conventional methods. It should be an essential part of every sight and eye test.
An Optomap scan costs £40, this is far less than the cost of missing a serious problem with your eyes
There are certain conditions where an optomap will be essential to assess signs of potential issues that could threaten your sight:
- High myopia/short sight
- Retinal detachment
- Retinal tears
- Choroidal naevus
- Toxoplasmosis scars
- Macula degeneration
- Hypertension/high blood pressure
- Hydroxychloroquine users
Normal examinations of the retina can only see about 15-30% of the retina. With the optomap, we can see over 80% of the retina in a single image. This means that the about we can see of your retina is nearly 3 times more with a significantly wider (ultra-wide) image. See the difference between existing technology and an Optomap image below:
We start by looking at the optic nerve. The circle shaped structure near the centre of the image. It has blood vessels coming out through here. We check the appearance of the nerves and blood vessels. Then we check an area of the retina called the macula. This is the region where the fine and detailed vision is detected by the eye. After this we analyse the more peripheral areas of the retina for damage, scarring, wear and tear or risks of other conditions of the eye.
