The reason you sometimes see sparkles is because of an eye condition know as posterior vitreous detachment.
Posterior vitreous detachment (PVD) occurs when the gel that fills the eyeball separates from the retina.
It's a natural, normal part of aging. PVD can cause floaters or flashes in your sight, which usually become less noticeable over time.
The condition isn't painful, and it doesn't cause vision loss on its own.
No specific treatment is needed for PVD.
That said, complications of PVD are rare but can be serious and require urgent treatment, such as laser for a retinal tear or surgery for a retinal detachment.
For this reason, one or more checkups are recommended within 3 months after the onset of PVD.
As long as you do not develop a retinal tear or retinal detachment, a PVD itself does not pose a threat to sight loss and the floaters and flashes slowly subside for a majority of patients within 3-6 months.
In these cases, no specific treatment is needed.
A vitreous detachment does not harm vision on its own.
But in some cases, the fibers can pull so hard on the retina that they create a macular hole, or a retinal tear that leads to a retinal detachment.
These are serious conditions.
PVD isn't painful and it doesn't cause sight loss, but you may have symptoms such as seeing floaters (small dark spots or shapes) and flashing lights.
These symptoms will calm down as your brain learns to ignore them.
Does posterior vitreous detachment (PVD) lead to vision loss? PVD isn't painful, and it usually doesn't cause vision loss unless you have a complication, such as: Retinal tear. Retinal detachment.
As with retinal detachment, stress on its own cannot cause a posterior vitreous detachment (PVD).
A PVD is simply a normal process of aging in which the vitreous gel that fills the eye separates from the back of the eye.
If we reduce our water intake, this concentration may change”.
We risk the most over the summer. “For instance, the majority of retinal detachment cases happen during the summer.
Severe dehydration may cause a contraction of the vitreous.
If your vitreous detachment causes a serious condition like a retinal tear you may need treatment for that condition.
If your floaters still bother you after a few months and make it hard to see clearly, your eye doctor might suggest a surgery called a vitrectomy to remove them.
