When to See a Doctor

Seek professional care if you experience any of the following symptoms

  • Eyes are sensitive to bright light

Possible Causes

  • Migraine

    A type of headache with throbbing, pulsating pain on one side of the head. Sometimes, visual changes like sparkling occur before the headache. The pain may worsen on exposure to bright lights or wild noise. Triggers for migraine include stress, poor sleep, caffeine and hormonal changes in women.

  • Vogt-Koyanagi-Harada disease

    This disease occurs when the body's own immune system accidentally attacks a particular type of pigment cells called "melanocytes". The eyes are often affected, causing blurring of vision, flashing lights, or floaters. Other areas that can be affected include the inner ear, causing loss of hearing. The surface layer of the brain can also be affected, causing headaches and neck stiffness.

  • Cryptococcosis

    Cryptococcosis is a potentially life-threatening infection of mainly the lungs, presenting as a pneumonia, and the brain, presenting as meningitis. It is caused by fungus, cryptococcosis neoformans and can spread to humans through contact with pigeon droppings or unwashed raw fruits.

  • Cluster headache
  • Age-related macular degeneration
  • Toxoplasma

Related Serious Diseases

  • Brain tumor

    A brain tumor is a collection, or growth, of abnormal cells in your brain. They can be cancerous or non-cancerous. Cancerous brain tumors can begin either in the brain (primary tumor) or spread from another cancerous organ (secondary tumor). Primary brain tumors are caused when abnormal changes occur to the DNA of brain cells.
