Retinal Tear

A retinal tear usually occurs as a result of the shrinking of the vitreous humor and pulling on the retina, a process known as posterior vitreous detachment.
Retinal tears are often located in the periphery of the retina and have little effect on vision. However, retinal tears can lead to retinal detachment. This occurs as vitreous humor flows through the retinal tear into the space in between the retina and its supporting layers. Retinal tears may occur without any symptoms but may also result in floaters, flashing lights, and decreased vision.
Patients with retinal tears need urgent treatment, often with a laser, to create a scar around the tear and to prevent retinal detachment.
