PHOTORETINITIS Meaning and
Definition
-
Photoretinitis is a medical condition that refers to the inflammation and damage experienced by the retina, the light-sensitive tissue at the back of the eye, due to exposure to intense or excessive light. Also known as phototoxic retinopathy, this condition commonly occurs as a result of direct or prolonged exposure to bright sources of light, such as the sun, arc welding, or laser beams.
The inflammation and damage to the retina can lead to various visual impairments and symptoms, including blurred vision, eye pain or discomfort, sensitivity to light (photophobia), and the appearance of dark spots or floaters in the visual field. In severe cases, permanent vision loss may occur.
Photoretinitis can be caused by several factors, including ultraviolet (UV) radiation, visible light, or infrared radiation, each having different effects on the retina. Ultraviolet radiation, for instance, can cause the damage of photoreceptor cells, while visible light can lead to the formation of free radicals that harm the retina's delicate structures.
Treatment for photoretinitis typically focuses on relieving the symptoms and preventing further damage to the retina. This may include the use of protective eyewear, lubricating eye drops, or anti-inflammatory medications. It is crucial to seek medical attention promptly if symptoms of photoretinitis arise, as early intervention can be vital in preventing irreversible damage and preserving vision.

Etymology of PHOTORETINITIS
The word "photoretinitis" is derived from two main roots: "photo-" and "retinitis".
1. "Photo-" comes from the Greek word "phōs" (φῶς), meaning "light". It is commonly used as a prefix in scientific terms related to light or photographs (e.g., photon, photosynthesis).
2. "Retinitis" is derived from the Latin word "retina", which refers to the light-sensitive tissue at the back of the eyeball. "Retinitis" is a medical term used to describe inflammation of the retina.
Therefore, the word "photoretinitis" combines these two roots to describe an inflammation of the retina caused by exposure to light.
