Observation
Most uncomplicated PVDs are managed with explanation, follow-up and clear instructions about symptoms that require urgent return.
Vitreous & retina
Posterior vitreous detachment (PVD)
PVD is a common age-related separation of the vitreous gel from the retina. Its symptoms overlap with retinal tears, so a dilated examination matters.
Know the retinal warning signs
Many new floaters, repeated flashes, a curtain or shadow, sudden blur or loss of vision require urgent in-person retinal assessment.
Understanding the concern
A clear diagnosis comes before a treatment plan
The vitreous is a clear gel that fills the centre of the eye. With age it becomes more liquid and can separate from the retina, a process called posterior vitreous detachment.
PVD itself often settles without treatment, but the separation can occasionally pull hard enough to create a retinal tear or bleeding. New symptoms should therefore be examined rather than self-diagnosed.
What patients notice
Symptoms often reported with PVD
These features can overlap with other eye conditions. Examination is needed to establish the cause.
- A new ring, cobweb or cluster of floaters
- Brief flashes at the side of vision
- Moving dots or strands
- Mild haze
- No symptoms in some cases
Specialist assessment
What the consultation may involve
The examination confirms vitreous separation and checks the entire peripheral retina for tears or detachment.
01
Dilated retinal examination
A wide retinal view is used to look for tears, holes, pigment, bleeding or detachment.
02
Vitreous and macular review
The clinician assesses whether the vitreous has fully separated and whether there is residual traction on the macula.
03
Follow-up plan
Repeat examination may be advised because a tear can occasionally develop after the first assessment while the vitreous is still changing.
Treatment planning
Monitoring and treatment of complications
An uncomplicated PVD does not usually require a procedure. Treatment is directed at a retinal tear, detachment, bleeding or significant traction if one is found.
Retinal tear treatment
Laser or cryotherapy may be advised when a retinal tear is found.
Surgery for a complication
Retinal detachment, non-clearing haemorrhage or vision-threatening vitreomacular traction may require surgery.
From first assessment to follow-up
- 01Arrange an urgent eye examination for new symptoms
- 02Confirm PVD and exclude a retinal tear
- 03Set follow-up according to examination findings and risk
- 04Return urgently for an increase in floaters, flashes, shadow or blur
- 05Treat any retinal complication without delay

Distinguishing PVD from a retinal tear
Prof. Amer Awan's vitreoretinal practice covers the retinal tears, detachment, macular traction and bleeding that must be considered when PVD symptoms begin. A dilated examination is needed to distinguish these possibilities.
Questions patients ask
About Posterior vitreous detachment
Is PVD the same as retinal detachment?
No. PVD is separation of vitreous gel from the retina. Retinal detachment is separation of the retina itself. PVD can occasionally cause a tear that leads to detachment.
Why might I need another examination?
The vitreous can continue to change after the first visit, so follow-up may be recommended according to symptoms and risk factors.
Can I prevent PVD?
It is usually an age-related change and often cannot be prevented. The practical priority is recognising new symptoms and arranging a retinal examination without delay.
