Eye Health
Diabetic eye disease
The tissue, nerve and blood vessel changes that occur in diabetes can affect the body in a number of ways, and the eye is no exception. People with diabetes can experience fluctuating vision, dry eye and difficulty wearing contact lenses, or develop cataracts at a younger age than others.
However, the most important effect that needs to be checked for is diabetic retinopathy - damage to the retina, the light-sensitive layer at the back of our eyes. Diabetic retinopathy can, if severe enough, lead to blindness. Careful and regular monitoring of eye health is essential to minimise the risks associated with this condition.
Risk Factors for Diabetic Retinopathy
Some diabetics are at higher risk for eye problems than others. Diabetic retinopathy is more common
- the longer you've had diabetes
- if your bood sugar levels have been very high
- if your blood sugar levels have not been well-controlled - ‘up and down'.
How can Sharpe & Fowler help?
A diabetic eye examination involves checking the vision and the health of the eye. The back of the eye, where diabetic retinopathy is seen is carefully examined. Usually a set of retinal photographs are taken which give us the ability to monitor changes over time. We'll be able to show you the photos on the day, to help explain any changes we see. Your GP will also be sent a copy of our findings for follow-up as needed.
Usually, dilating drops are needed to get the best view of the back of the eye. If you have an appointment for a diabetic review, remember to bring some sunglasses to help reduce the glare afterwards. Either arrange someone else to drive you, or plan to have some time in town until your vision returns to normal.
How often should people with diabetes have their eyes examined?
- Current guidelines recommend that everyone has a diabetic eye examination when they are first diagnosed with diabetes.
- If there are no signs of change in the retina, they should be reviewed again every 1-2 years.
- If changes in the retina are seen, then depending on the severity, review may be more frequent, or they may be referred to an ophthalmologist for treatment.
- If you are diabetic, and feel that there has been a change to your vision, your eyes should be seen promptly even if you are not due for your next review.

Eye Health Facts
What is colour blindness?
The eye determines the colour of what we are looking at by how much response comes from each of three types of light receptors (red, green, or blue). The most common type of colour vision deficiency is where one type of light receptor, usually red or green, doesn't work as well.
This reduces the range and appearance of colours, with some colours that are clearly different to normal eyes appearing the same to a colour deficient people. What do they see? one demo, another.
True colour blindness - black and white only - is very rare. Colour vision deficiencies are usually inherited, and are more common in boys than girls.
