Glaucoma is a group of eye diseases that affect the optic nerve, which connects the eye to the brain. It often affects both eyes usually to varying degrees.
The eyeball contains a fluid called aqueous humour, which is produced by the eye, with any excess drained through tubes. When the fluid cannot drain properly, this causes a build up of pressure in the eye known as intraocular pressure. Glaucoma develops when this increased pressure damages the optic nerve and the nerve fibres from the retina.
In acute glaucoma cases this pressure rises rapidly to higher levels, causing pain.
As most cases won’t have any symptoms, one of the best ways to detect glaucoma is during a routine eye test – that is why it is so important to have one regularly.
Keratoconus is a disorder that affects the cornea (the clear front surface of the eye). The cornea becomes thin and steep and becomes more cone shaped, resulting in distorted vision, sensitivity to light, and decreased vision.
Keratoconus can affect a person’s ability to read or drive, which can be a major obstacle for people. Symptoms typically start usually in your late teens or 20’s.
Luckily, this is a condition that can be diagnosed through a routine eye exam, at Optical Outlook we screen all patients for this condition
If you have diabetes, you’re at risk of developing an eye condition known as diabetic retinopathy, a complication of diabetes that damages the light-sensitive layer at the back of the eye (retina). Left undiagnosed and untreated, diabetic retinopathy can lead to sight loss.
In its early stages, diabetic retinopathy does not usually cause any noticeable symptoms – so you may not even know you have it.
That’s why screening is such an important part of care for diabetics. Screening can detect the condition before you notice any changes to your vision, and if it is detected early enough, management of the condition can stop it getting worse. Otherwise, by the time symptoms become noticeable, it can be much more difficult to treat
Cataract are very common- they are the main cause of impaired vision worldwide.
Cataracts usually develop slowly over many years, so you may not notice symptoms at first. They often develop in both eyes, although each eye can be affected differently. Cataracts are not painful, they do not make your eyes red or irritated.
Some cataracts never progress to the point that they need to be removed. It is important that the cataract is monitored regularly . As the cataract progresses, it may start to affect your vision and you may need surgery
Your optometrist will refer you to a hospital to have the cataract removed. This is done as day surgery under local anaesthetic, so you will be awake during the procedure and can go home on the same day. Once you have the cataract removed it will not return.
