A retinal tear is a condition where a small break occurs in the retina, the light-sensitive tissue at the back of the eye. This can happen due to various reasons, such as aging, trauma, or extreme nearsightedness. When the retina is torn, it can lead to serious complications, including retinal detachment, which may result in vision loss if not treated promptly. Symptoms of a retinal tear may include sudden flashes of light, floaters, or a shadow in the peripheral vision. If you experience these symptoms, it is essential to seek immediate medical attention from an eye care professional, such as an ophthalmologist, to prevent further damage to the eye and preserve vision.
