The vitreous is a open, gel-like fluid that fill the heart of your orb. As we age, this gel naturally begin to shrink and liquefy. Eventually, it may pull away from the retina, a summons cognize as a Posterior Vitreous Detachment (PVD). As this happens, the shrivel glassy tower on the retina, make the brain to rede this mechanical pull as flashes of light.
Common Causes of Photopsia
While the most frequent grounds of light flash in eye is the natural aging of the vitreous, respective other element can lead to these visual disturbances. Identify the root cause is crucial for determining the appropriate trend of activity.
- Posterior Vitreous Detachment (PVD): The most common cause in senior adult, where the vitrified gel force forth from the retinal surface.
- Retinal Tear or Insularism: A dangerous condition where the tugging of the vitrified is strong enough to make a hole or tear in the retina, or pull the retina out from the paries of the eye entirely.
- Opthalmic Hemicrania: Hemicrania that involve the optic pallium of the encephalon, often causing flickering lights, zig line, or dim place, usually in both eyes.
- Trauma or Injury: A blow to the brain or eye can physically shake the retina, resulting in sudden flashing.
