Eye Diseases

Macular Degeneration: This is a condition that causes loss of central vision and tends to occur in older people. There are two types, 'wet' and 'dry'. Dry macular degeneration causes gradual loss of central vision typically over several years. Wet macular degeneration causes rapid loss of central vision typically within weeks and if untreated can cause blindness within months. If someone has the dry macular degeneration there is a small chance every year that they can develop the wet form.

Diabetic Retinopathy: People who have diabetes can develop complications of their disease that can cause loss of vision. This can be due to abnormal blood vessels forming in the eye (neovascularisation), swelling at the back of the eye (macular oedema) or poor circulation at the back of the eye (macular ischaemia).

Retinal Vein Occlusion: As you get older there is a small risk of a blocked blood vessel in your eye (retinal vein occlusion). This causes bleeding at the back of the eye (retinal haemorrhages) and loss of vision. High blood pressure and diabetes increase your risk of a retinal vein occlusion.

Glaucoma: Glaucoma is the name given to a group of eye conditions which cause optic nerve damage and can affect your vision. Glaucoma damages the optic nerve at the point where it leaves your eye. Glaucoma damage may be caused by raised eye pressure or a weakness in the optic nerve. Or you may have an eye pressure within normal limits but the damage occurs because there is a weakness in the optic nerve. In most cases, high pressure and weakness in the optic nerve are both involved to a varying extent. (Eye pressure is not connected to your blood pressure).

There are four main types of glaucoma:

- Primary open angle glaucoma (POAG) also known as chronic glaucoma
- Acute angle closure glaucoma
- Secondary glaucoma
- Developmental glaucoma

Your peripheral vision, which is the vision you have around the edge of what you are looking directly at, gradually gets worse if you have POAG. The centre of the visual field is affected last so that eventually it is like looking through a long tube - this is so-called "tunnel vision". The most common risk factors are, age, family history and diabetes.The main treatment for POAG aims to reduce the pressure in your eye. Treatment to lower your eye pressure usually starts with eye drops, which are normally effective in the majority of cases. Should medical treatment fail, then laser or surgical intervention would be the treatment of choice when indicated.

Poor Vision Following Cataract Surgery: Cataract surgery has a high success rate at improving vision. However, some people can develop poor vision after cataract surgery caused by swelling of the back of the eye (pseudophakic macular oedema).

Unexplained Reduced Central Vision: Some people can develop difficulty with their central vision due to abnormal scar tissue causing pulling or traction at the back of the eye. Often this will not be diagnosed by a normal examination performed by your optician and will require a special scan (Spectral Domain OCT) which can be performed at the BMI Lincoln Hospital.
