Common Causes Of Iritis

Eye Injuries

Iritis caused by eye injuries is referred to as traumatic iritis. Blunt eye injury is usually the most prevalent cause of traumatic iritis, but injuries from firecrackers, electric shock from a taser, motor vehicle accidents, pellet gun projectiles, fishing hook weights, water balloon slingshots, batteries, and many others can cause iritis to develop. Around twenty percent of all cases of iritis can be attributed to eye injuries. When the eye sustains trauma, the cells in the eye become injured, and a good number of them die. When cell death occurs, necrotic products or byproducts of cell death are produced, and this triggers an inflammatory reaction from the immune system. Along with causing traumatic iritis, an eye injury creates a build-up of white blood cells and proteinaceous fluids in the anterior region of the eye. This buildup happens because the inflammatory response allows for the permeation of immune factors through the blood vessel walls in the affected area. This inflammation precipitated buildup in the eye can cause an increase in interocular pressure. When traumatic iritis is not adequately treated, the patient can experience vision loss.
