Common Eye Conditions

NEUROLOGICAL VISION IMPAIRMENT

  • Neurological Vision Impairment is the term used to describe a vision impairment caused by damage to the brain, such as a stroke (cerebro-vascular accident – CVA), tumour, brain injury or pathological degenerative disease. Vision impairment is generally thought of as damage to or deterioration of the eyes. There are many different areas of the brain that interpret what our eyes see. When these are damaged, the eyes may still function but the message might be misinterpreted or unable to get through to the brain resulting in NVI.

RETINITIS PIGMENTOSA

  • Retinitis Pigmentosa
  • Retinitis Pigmentosa is an inherited, degenerative condition that affects the retina – the lightsensitive part of the eye. The retina is made up of millions of light sensitive photoreceptor cells that transmit light via the optic nerve to the brain. RP causes some of these photoreceptor cells to fade gradually and die
    thereby losing the ability to transmit the visual message to the brain. People usually start noticing their vision fading in their teenage years.
