There are third, fourth, and sixth nerve paralysis, each type give different symptoms. In the third nerve paralysis, there is complete ptosis and the eye is slightly divergent and depressed. Fourth nerve paralysis causes upward deviation if the eye with failure of depression on adduction. Trauma is the major caused of this paralysis. Sixth nerve paralysis causes convergent squint in the primary position with failure of abducion of the affected eye. less

Pain and temporary vision loss are common symptoms of optic neuritis. Optic neuritis usually develops in association with an autoimmune disorder that may be triggered by an infection. In some people, signs and symptoms of optic neuritis may be an indication of multiple sclerosis, a condition resulting in inflammation and damage to nerves in your brain and spinal cord. Most people who experience a single episode of optic neuritis eventually recover their vision. Treatment with steroid medications may speed up vision recovery after optic neuritis. less

It is usually associated with constant exposure to wind, sun, sand, and dust. Pterygium may be unilateral or bilateral. They may be a genetic predisposition, but o hereditary pattern has been described. Excision of the pterygium is indicated if the growth threaten to interfere with vision by approaching the visual axis. less
