It affects different structures of the eye. The severity of vision impairment depends on which structures are affected. This condition can affect one or both eyes and it may be associated with other developmental abnormalities. Cortical Vision Impairment. Cortical vision impairment is an umbrella term to describe vision impairment in normal healthy eyes. It is caused by disruption to the parts of the brain which control vision. This often results in variable visual responses. Nystagmus. Nystagmus is continual, involuntary, fine movement of both eyes. It can be present by itself but is commonly associated with other eye conditions that cause blurred vision. Children often instinctively adopt a head posture so the eyes are in a position where there is less movement. This position is known as the null point. Poor health and fatigue can make the nystagmus more pronounced thereby reducing vision further. Optic Nerve Hypoplasia. Optic Nerve Hypoplasia is caused when the optic nerve, responsible for transmitting visual signals from the retina to the brain, is not fully developed thereby passing less information from the retina to the brain. It may coexist with other conditions such as septo-optic dysplasia. Next.
