Photic retinopathy
Photic Retinopathy
Photic retinopathy (pronounced: /ˈfoʊtɪk rɛtɪˈnɒpəθi/), also known as light-induced retinopathy, is a medical condition that involves damage to the retina due to prolonged or intense exposure to light.
Etymology
The term "photic" comes from the Greek word "phōs", which means light, and "retinopathy" is derived from the Greek words "retina" and "pathos", meaning disease. Thus, photic retinopathy can be translated as "light-induced disease of the retina".
Definition
Photic retinopathy is a type of eye injury that occurs when the retina, the light-sensitive tissue at the back of the eye, is exposed to an excessive amount of light. This can occur from looking directly at the sun (a condition known as solar retinopathy), or from exposure to other sources of intense light, such as a welder's arc, a photographer's flood lamps, or even certain types of lasers.
Symptoms
Symptoms of photic retinopathy can include blurred vision, eye pain, headache, light sensitivity, and a decrease in central vision. In severe cases, it can lead to vision loss.
Treatment
Treatment for photic retinopathy primarily involves avoiding further exposure to intense light. In some cases, corticosteroid therapy may be used to reduce inflammation in the retina. It is important to seek medical attention if symptoms of photic retinopathy are experienced.
