Optomap – Daytona Optomap system

An Optomap® using Optos® Daytona Plus literally gives you a 200° field of view of your retina. See Figure 1. This is massive compared to 45° using traditional retinal photography.

Retinal photography is so old school. This technology has been around for decades, started with film then digital but the principles are the same. It is good but with limitations compared to current technology.

To give you a perspective, Figure 2 is a pair of images. On the left was taken with traditional retinal camera and on the right was an Optomap® taken with our Optos® Daytona Plus. They are size-matched of the same eye in real clinical setting of an actual patient (not a model).

As well as giving your an ultra-widefield scan of your retina, Daytona Plus is also able to perform a medical imaging technique called autofluorescence imaging of your retina. Autofluorescence imaging is relatively new in eyecare. Currently, not many NHS hospitals are able to perform that but we can!

This technology shows up certain conditions, such as atrophic macular degeneration. Usually this would be relatively invisible to traditional techniques. Combined with its ultra-widefield capability, Optos® Daytona Plus is just something else entirely.

We thoroughly enjoy this modern and hi-tech piece of equipment like this to give you the advanced eye care you deserve.

EyeDream has arrived!

Welcome to a new world of visual freedom!

By choosing EyeDream contact lenses to correct your vision you are about to rediscover the convenience and comfort of clear vision without the need to wear spectacles or contact lenses during the day.

The ‘natural vision’ effect of EyeDream is created by wearing specially designed contact lenses during the night whilst you are asleep. The lenses gently reshape the corneas allowing you to see clearly during the day when the lenses are removed.

Remarkable Milestone for our Patient!

What a remarkable milestone. Visioncare is honoured to have looked after the delightful Joan Rose for the past 30 years. An artist, a mother, and grandmother she has been a regular visitor to the New Barnet practice since the mid 1980’s and she turns 100 in March! The serene painting you see on the wall behind in our consultation room is one of her creations. We congratulate this outstanding woman.

Vision and Exercise

Recent research has shown that exercise  as well as elevating the heart rate may improve vision.

The wide array of benefits from physical exercise is long,including mood enhancement, improved sleep, reduced risk of disease and now researchers believe vision improvement can be added to the mix.

A recent study at UC Santa Barbara recorded vision improevemnt among 18 subject participants who had riding a stationary bike at low intensity.

Tom Bullock a post-doctoral researcher at UC Santa Barbara,said that previous studies had resulted in improved vision among mice during physical activity.

“However, given the vast differences between mouse and primate brains, it is unclear whether these results also apply to the human brain,” he elaborated. “Our data provides evidence that there may well be a common mechanism,” Dr Bullock stated.

During the research program, the 18 volunteers each wore a skull cap cover containing scalp electrodes and a wireless heart rate monitor. The visual neural activity was analysed while the study participants were at rest, as well as during a variety of cycling intensity exercise.

Reconstructed tuning curves using a computational algorithm, allowing researchers to estimate how well large populations of neurons in the visual cortex
were representing different stimulus orientations.

The results suggested that the neurons became more sensitive to visual stimuli during low intensity exercise than during high intensity exercise or rest.

Other research planned by the lab includes a study determining how exercise influences visual working memory.

Maybe time to start moving to help both your heart and your eyes?
