Clare Darbyshire Optician are the proud owners of one of the first 3D OCT in Shropshire
The retina can be seriously affected by many common diseases including age related macular degeneration, glaucoma and diabetes which can lead to visual impairment and even blindness. By having this technology in practice Clare Darbyshire opticians can pick up problems at a much earlier stage enabling better treatment options. Regular scans also mean even the most subtle changes in the retina can be detected and this gives an invaluable on-going record of health and condition of your eye.
What can the scan check for?
Common conditions identified through regular OCT screening include:
A macular hole is a small hole in the macular –the part of the retina which is responsible for our sharp, detailed central vision. This is the vision we use when we are looking directly at things, when reading, sewing or using a computer. There are many causes of macular holes. One is caused by vitreous detachment, when the vitreous pulls away from the back of the eye and sometimes it does not ‘let go’ and eventually tears the retina, leaving a hole. Extreme exposure to sunlight (for example staring at the sun during an eclipse) can also cause a macular hole to develop.
Vitreomacular traction can clearly be diagnosed through OCT providing invaluable information about the current relationship between the vitreous and retinal surface of the eye. As people get older the vitreous jelly that takes up the space in our eyeball can change. It can become less firm and can move away from the back of the eye towards the centre, in some cases parts do not detach and cause ‘pulling’ of the retinal surface. The danger of a vitreous detachment is that there is no pain and your eyesight may seem unchanged but the back of your eye may be being damaged.
Optometrist, Clare Darbyshire says “We were one of the first opticians in Shropshire to have the original digital photography 8 years ago and are always striving to remain at the forefront of eye care technology. Scans using this new instrument really do make a difference to treatment outcomes and gives patients the peace of mind that the health of their eyes is being monitored over the long term.
Age related macular degeneration
Macular degeneration causes the gradual breakdown of the macular (the central portion of the eye). OCT cannot only identify this condition and its type (there are two types, wet and dry) but also monitor its progress, for example if you are undergoing treatment for such a condition. Unfortunately the risk of developing macular degeneration increases with age, and it is the most common cause of vision loss in individuals over the age of fifty.
Diabetic retinopathy is s major cause of visual impairment among adults. Here in the UK, more than two million people have been identified as having diabetes. OCT examination enables early detection, which greatly improves the success rate of treatment.
Glaucoma damages the optic nerve at the point where it leaves the eye. Recent statistics suggest that some form of glaucoma affects around two in every 100 people over the age of 40. The danger with chronic glaucoma is that there is no pain and your eyesight will seem to be unchanged, but your vision is being damaged. An OCT examination will confirm if you are at risk, or indeed what stages of glaucoma you may have.
