Eye Conditions

This section is a resource for those who wish to understand a little more about specific eye conditions. If you are unclear about a specific condition, look at “Eye Symptoms” to see if you are affected by any on the list. If you cannot find what you are looking for or have any questions please do not hesitate to contact us at Centre for Sight and one of our Patient Counsellors will be able to help you.

Although there are numerous eye conditions, here is a list of some of the more commonly encountered problems. You can learn more by clicking on the condition:

Shortsight

Short–sightedness, or myopia, is a relatively common eye condition that causes distance vision to appear out of focus, while close objects can be seen clearly. Most people will use glasses or contact lenses to help put objects back into focus.

Fuchs Endothelial Dystrophy

Fuchs Endothelial Dystrophy is a condition where the cells on the back of the cornea drop out. These endothelial cells are important for keeping the cornea clear and as a result of loss, the cornea fills with fluid which in turns affects corneal transparency. There are treatment options available.

Farsight

Farsightedness or Hyperopia is a common form of visual impairment. When the eye receives an image it focuses this behind the eye rather than on the back of the eye. Strong glasses or contact lenses are required to help bring the rays upstream to focus on the retina.

Keratoconus

The word Keratoconus is formed by two Greek words: kerato, meaning cornea, and konos, meaning cone. Keratoconus is a condition in which the shape of the cornea, which is usually round, is distorted, developing a cone-shaped bulge, resulting in harm to vision.

Astigmatism

Astigmatism is often found in combination with shortsightedness and farsightedness and contributes to blurry vision. This occurs because the cornea is shaped like a rugby ball rather than a soccer ball. Depending on how light rays enter the cornea, they may be focussed to different points – see the diagram below.

Dry Eye Conditions

Dry eye or Dry Eye Syndrome is a very common condition that increases with age and probably affects 2 million people in the UK – usually more women than men.

Presbyopia

Reading glasses are something many of us will end up depending on as we get older. This is called ‘presbyopia’. For some of you it’s a nuisance, for others it’s a major impairment.

Why I Need Glasses

This page briefly describes the various conditions that result in the need for glasses or contact lenses and will help understand the various Vision Correction conditions available at Centre for Sight.

Glaucoma

The word glaucoma covers a group of eye conditions that cause optic nerve damage, which can affect vision. In the UK, about 1 in 50 people aged over 40 have the condition.

Cataract

A cataract is a loss of transparency or clouding of the normally clear lens of the eye. This lens is a part of the eye that helps focus light on the retina. It is located behind the iris.

Stem Cell Deficiency

Centre for Sight has been at the forefront of eye-care since the company began in 1996. Stem cell transplantation has been one of the biggest game changers for medicine, but each procedure is specific to a small part of the human anatomy.
