A torn retina is a serious problem that makes your vision blurry. It is when the retina has a tear or hole, like a rip in cloth. A torn retina often leads to a more serious condition called a detached retina. This is where the retina is lifted away from the back of the eye. A torn retina must be treated right away to avoid further vision problems.

Ocular hypertension is when the pressure inside the eye (intraocular pressure or IOP) is higher than normal.

With ocular hypertension, the front of the eye does not drain fluid properly. This causes eye pressure to build up. Higher than normal eye pressure can cause glaucoma. Glaucoma is a disease where eye pressure damages the optic nerve, causing vision loss.

A cataract is a clouding or opacity of the lens inside the eye. It causes gradual blurring of vision and often glare.

Inside your eye, behind the iris and pupil is a lens. In a normal eye, this lens is clear. It helps focus light rays onto the back of the eye (the retina), which sends messages to the brain allowing us to see.

When cataract develops, the lens becomes cloudy and prevents the light rays from passing on to the retina. The picture that the retina receives becomes dull and fuzzy.

Cataract usually forms slowly and most people experience a gradual blurring of vision.

A transient ischaemic attack (TIA) or ‘mini-stroke’ is caused by a temporary disruption in the blood supply to part of the brain.

The disruption in blood supply results in a lack of oxygen to the brain.

This can cause sudden symptoms similar to a stroke, such as speech and visual disturbance, and numbness or weakness in the face, arms and legs.

But a TIA does not last as long as a stroke. The effects last a few minutes to a few hours and fully resolve within 24 hours.

Winter can be tough on the eyes and taking good care of your eyes during the colder months can help prevent irritation and other problems.

During the winter months, you may notice you need to wear your glasses more, especially as you get older. This is because when there is less light available, your pupil expands which reduces the eye's depth of focus and means that you notice blurriness. Make sure you have good lighting, for example, a lamp near the chair where you sit to read, and that you turn it on as soon as it is getting dark.

What are soft contact lenses? Soft contact lenses are made of a sponge-like material. They absorb water and most soft lenses have a water content of over 50%. This is not pure water but must match the salt concentration of your tears. Sponges are excellent for growing bacteria, which can cause infection, so it is vital that you clean the lenses carefully and disinfect them to reduce the risk of harming your eyes. If you wear daily disposable contact lenses you should never reuse them.

Probably the most common question I have in clinic is about floaters in the vision. But what exactly are they? I thought I’d write about this in the blog this month as last week I had a sudden new very large floater and it needed assessment.
More about that later…

Many women experience a range of mental and physical symptoms as they transition through the menopause. These commonly include: hot flushes, night sweats, difficulty sleeping, problems with memory & concentration and low libido. But, did you know that fluctuations in your hormones during the menopause can also have a significant impact on your eye health?

Some people express concern about the appearance of the eyes. One question is often about the greyish or white ring around the edge of the cornea (the front surface of the eye).
