Common Eye Conditions

What is blepharitis? Blepharitis causes eyelids to become red, swollen and inflamed. It doesn’t normally cause serious damage to the eyes, but it can be very uncomfortable. It tends to be a long-term condition, which means you’re likely to need ongoing treatment. Severe cases do have a risk of causing long-term damage, but fortunately these are quite rare. We stock products that help you to manage blepharitis to keep your eyes comfortable.

What is a cataract? A cataract happens when the lens within your eye becomes cloudy. It can happen to all of the lens or just part of it. There are different types of cataract, but the most common is age-related cataract, which is more common in older people. It is likely to be found to some degree in almost all people over 65. If you have cataracts but have no symptoms, or the effect on your vision is mild, treatment may not be needed. However, surgery may be required if your cataracts start to affect your day-to-day activities, such as your ability to recognise people, read or drive.

What is dry eye? People with dry eye either don’t make enough normal (lubricating) tears or the ones that they make are of poor quality, causing the tears to dry up too quickly and the front of the eye to become dry and irritated. As a result, dry eye can be uncomfortable and cause the eye to produce the watery type of tears. This only helps for a short time – leaving the eye uncomfortable and gritty.

Diabetes is a common condition where there is too much sugar in the blood. It can be treated, but even with treatment, people with diabetes have a higher risk of developing eye problems.People with diabetes can have eye problems due to leaky or blocked blood vessels in the retina, the layer at the back of the eye, over time this can cause sight loss.The longer you have diabetes, the more likely you are to develop eye problems. If your diabetes is poorly controlled this also increases the chance that you will develop diabetic eye disease, also known as diabetic retinopathy.

Tiny spots, lines, flashes or shapes in your vision are known as flashes and floaters. Sometimes the jelly inside your eye shrinks a little and tugs on the retina (the light-sensitive layer) at the back of your eye. This can cause flashes of light at the edge of your vision. This is different from the disturbance of vision that can happen with a migraine.Often, people who have healthy eyes see floaters. They appear as spots, lines or cobweb effects, usually when you look at a plain surface such as a white wall, screen or a clear blue sky. They are usually caused by cells clumping together in the clear jelly in the main part of your eye and casting shadows on your retina Lots of people experience them and they usually aren’t cause for alarm. However If you suddenly notice a shower of new floaters, or floaters along with flashes or a dark shadow or a ‘curtain’ in your vision, these symptoms can mean that the retina is tearing. If you notice any of these symptoms, you need prompt advice and attention.Contact Gorseinon Eye Centre right away for advice.

What is glaucoma? Glaucoma is the name given to a group of eye conditions where the optic nerve at the back of the eye is damaged. It is often linked with raised pressure within the eye, although the eye pressure can sometimes be normal. When the nerve is damaged, it can start to cause problems with the peripheral vision (side vision), and if left untreated can cause permanent damage. With early treatment, further damage to vision can be prevented. If you are over 40 years old and a member of your immediate family has been diagnosed with glaucoma then you are entitled to an annual NHS test.

AMD is a condition that affects the central part of the vision. It is caused by damage to the macular region of the eye, which is the part of the retina that provides your detailed vision. It doesn’t normally affect your peripheral (side) vision, so while objects in the centre of your vision may become difficult to see, the vision to the side and edges should not be affected.

There are two main types of AMD – dry and wet. Dry AMD, sometimes referred to as wear and tear, is caused by a build-up of waste within the cells of the eye that react to light, these are called drusen. Drusen stop the cells from reacting properly to light. This form of AMD usually develops slowly. Wet AMD happens when new blood vessels grow behind the macula. These blood vessels can begin to leak and this can damage the cells in the macula region and stop them from working. This process can start very suddenly.Should you be concerned about a sudden distortion in your vision please contact Gorseinon Eye Centre right away for advice.
