Ocular Herpes - Herpes simplex, type I. This is the same virus which causes cold sores and it can infect the eyes also. It occurs on the cornea, usually only on one eye, and is also known as Herpes Keratitis. It can affect only the surface, or deeper layers, and can heal well, or can cause scarring, loss of vision and even blindness. Occasionally it develops inside the eye and is then known as Herpes Retinitis or Herpes Uveitis. Symptoms are blurred vision, pain, redness, and light sensitivity.

Halos are rings around lights.

Haze is corneal clouding that causes the sensation of looking through smoke or fog.

: photocoagulation - The process of tissue destruction accomplished by visible light radiation. Tissue is broken down by the light and "clots" as if it were cooked.

photovaporization - The process of tissue destruction as occurs with infra red light radiation such as with a yag laser. The target tissue is ionized causing plasma formation followed by a shock wave.
