6. Retinal Tears or Detachment: A Serious Threat to Vision

A retinal tear or detachment is a severe eye condition that can cause the sudden appearance of floaters. A retinal tear occurs when the retina pulls away from the underlying layer of blood vessels, while a retinal detachment involves the complete separation of the retina from the back of the eye. Both conditions can result in permanent vision loss if not treated promptly.
Symptoms of a retinal tear or detachment may include the sudden onset of new floaters, flashes of light, or a dark “curtain” obstructing part of the visual field. If you experience any of these symptoms, seek immediate medical attention, as early intervention is critical to preserving your vision. (6)
