This process is known as a posterior vitreous detachment (PVD). Because the vitrified is physically attach to the retina, as it pull away, it can create traction or drive ace on the retinal tissue. The brain construe this mechanical stimulation as flashes of light, still in the absence of an actual light source.
Beyond natural ageing, several other ingredient can actuate these optic disturbances:
- Retinal Tears or Detachment: If the vitreous pulling too hard, it can induce a bout in the retina. This is a medical pinch that can lead to permanent vision loss if not treated immediately.
- Optical Migraines: These are much characterize by optical disturbance, include shimmer light, zigzag line, or dim floater, even in the absence of a abominable worry.
- Blood Pressure Issue: Extreme fluctuations in profligate pressing can sometimes affect blood stream to the eyes, causing transitory visual phenomenon.
