The natural lens of the eye is contained within an elastic ‘capsular bag’. This bag is suspended within the eye by a series of ‘guy ropes’ around the outside of the lens called zonules. This is rather like a trampoline…
The optic nerve is the connection between the eye and the brain. It is responsible for transmitting the visual signal from the eye to the visual centres of the brain. Each optic nerve carries approximately 1 million nerve fibres. Damage…
The retina is the photographic film of the eye. It is covered in arteries carrying blood to the eye, and veins carrying blood away from the eye. There is one main central artery and vein, and multiple smaller arteries and…
The retina is a thin sheet of photographic film that lines the inside of the eye. The cavity of the eye is filled with a transparent gel, known as the vitreous. When we are born this vitreous gel is adherent…
Diabetes is the commonest cause of blindness in Europe in the under 65yr age group. Diabetes damages the fine blood vessels within the retina, or photographic film of the eye. The early stages of retinopathy has no symptoms. By the…
The photographic film of the eye is known as the retina. The macula is the very central retina, where all light is focused. It is responsible for the sharpest vision, especially reading vision. As we age debris collects underneath the…
The eye is principally divided into two separate compartments, the front or ‘anterior chamber’ which is filled with aqueous fluid, and the back or ‘posterior chamber’ which is filled with vitreous gel. When you are born this vitreous gel fills…
The vitreous gel is usually clear, apart from occasional transparent floaters. Blood is not transparent, so if bleeding occurs into the vitreous then the vitreous gel loses some of its transparency, resulting in dense ‘floaters’ or loss of vision. A…

Overview Just as you have a lens in glasses to focus, there is also a lens inside the eye to focus. This lens is held in position by a thin capsule. When the lens becomes cloudy it is known as…
