    Glaucoma is the term used to describe a group of eye diseases which damage the optic nerve, the nerve that connects the eye to the brain. If left untreated glaucoma can result in blindness. In the more common forms of glaucoma there is increased pressure in the eye which presses on the optic nerve and causes a gradual loss of peripheral vision. ... read more
  • Retinal Conditions

    The retina is the delicate lining at the back of the eye where the image you see of the world is formed and transmitted to the brain. Under certain conditions, especially with advancing age, the clear gel-like fluid which fills the eye can begin to recede.

    • Macular Degeneration

      Macular degeneration is the most common cause of decreased reading or detailed vision and usually affects people over 50 years of age. It can cause distortion of central vision and decreased colour vision. Side vision (peripheral vision), is not affected by macular degeneration. ... read more

It is an abnormal process in which the conjunctiva (a membrane that covers the white of the eye) grows into the cornea. Pterygia may be small or grow large enough to interfere with vision. It commonly occurs on the inner corner of the eye. ... read more
