Posterior vitreous detachment (PVD) is a natural aging process in which the vitreous gel pulls away from the retina. It’s typically benign but must be monitored for retinal tears, which can lead to retinal detachment.

Symptoms
Sudden floaters
Flashes of light
Cobweb-like shadows in vision
Findings
Weiss ring (circular floater)
Mobile vitreous gel on slit-lamp exam
No retinal breaks on exam (if uncomplicated)
Treatments
If no retinal tear is present, observation is usually sufficient. However, if a retinal tear is detected, laser treatment may be necessary to prevent further complications. Routine follow-up exams over the next few weeks are important to monitor for any changes.
Outcomes
Symptoms often fade over time and typically do not require treatment; however, it is important to monitor for the development of retinal tears, which may need prompt intervention.
