Optic nerve

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…

Vitreous Traction

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…

Vitreous Haemorrhage

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…

Floaters & Flashes

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…

Cataracts

Glasses (Refractive error / Laser)

The need for glasses is very common. This is known as refractive error. There are 4 common conditions that people require glasses for: Long-sightedness – This is when distance objects are in focus more clearly than near. Short-sightedness – This…

Dry or Watery Eye

The surface of the eye is a clear window known as the cornea. The clarity of vision through this clear window is highly dependent on the health of the tear film and eye lids. The tear film is made up…

Blepharitis

Blepharitis is incredibly common. In fact it is the commonest cause of red gritty eyes. What is Blepharitis? Blepharitis is a condition where the eye does not get enough moisturising oil and the eye becomes red and gritty. Many people…

Optic nerve

This connects the eye to the brain. It has over 1 million nerve fibres in each optic nerve. Problems with the nerve cause loss of fine vision, colour vision, and field of vision. The nerve may be damaged by eye…

Retina

This is the thin delicate photographic film of the eye that covers the inside of the eye. It provides both peripheral vision and central detailed vision. The finest vision is achieved at the very centre of the retina, known as…
