PVD is when the clear gel inside the eye separates from the retina — a normal age-related change. Most cases cause new floaters and flashes that fade over weeks. A small percentage tear the retina, which is why a same-week exam matters.
What helps
Mostly observation — with vigilance.
First step
Dilated retina exam
Once new floaters or flashes appear, a dilated exam looks for any retinal tear. Most are normal PVDs that need no treatment. Tears are far better caught early.
Most cases
Observation
Uncomplicated PVD doesn't require surgery or drops. The retina specialists' guidance: about 85% of patients have no complications, and symptoms typically fade over about 3 months as floaters drift out of the line of sight.
If tear is found
Laser retinopexy
A small retinal tear can be sealed in the office with a laser to prevent retinal detachment. Quick, well-tolerated, and very effective.
Rare
Vitrectomy for persistent floaters
For a small group whose floaters never settle and significantly affect daily function, vitrectomy surgery can remove them. Risks include cataract and (rarely) retinal detachment, so it's a careful decision.
Same-day care if
You see a sudden shower of new floaters, persistent flashing, or a dark curtain or shadow moving across your vision. These can signal retinal tear or retinal detachment — both are time-sensitive.
Common questions
Honest answers to common questions.
Is PVD dangerous?+
Most of the time, no. About 85% of patients have uncomplicated PVD with no lasting issues. The small percentage who develop a retinal tear or detachment need prompt treatment, which is why a same-week exam after new symptoms is the standard.
Will the floaters go away?+
Most fade meaningfully over several months as they drift out of the central line of sight and the brain learns to filter them. A few persist and become a chronic annoyance — rarely enough to need surgery.
Will it happen in my other eye too?+
Likely yes, often within a year or two. Symptoms in the second eye warrant the same same-week dilated exam, since the risk of retinal tear is the same.
Can I prevent PVD?+
No — it's a normal part of aging. Nearsighted people tend to have it earlier. Cataract surgery and eye trauma can also bring it on sooner. Regular dilated exams help catch any retinal complications early.
Why do I see flashes if no light is hitting my retina?+
When the vitreous tugs on the retina, the retinal cells fire in response. Your brain interprets that signal the only way it knows how — as flashes of light. Once the gel finishes separating, the flashes stop.
