# What causes cobwebs in vision?

Cobwebs or spider‑web patterns in vision usually represent vitreous floaters or condensed strands. They move with eye movements and drift when looking around.

## Underlying Changes

Liquefaction and collapse of the vitreous gel with age cause fibres to clump and cast shadows on the retina. Posterior vitreous detachment is a frequent cause and may occasionally pull on the retina, creating tears.

- High myopes and older adults are particularly prone
- Inflammation, haemorrhage, or surgery can increase vitreous opacities
- Patients often report a new web or veil across vision
- Risk of retinal tear is highest around the time of acute vitreous detachment

## Clinical Advice

New cobweb‑like floaters should prompt a dilated eye examination. Ongoing monitoring is needed if vitreoretinal traction or lattice degeneration is present.

- Emergency attention is required if accompanied by flashes or a curtain effect
- Most floaters become less noticeable over time as the brain adapts
- Vitrectomy for floaters is considered only in carefully selected cases
- Patients should avoid ignoring sudden changes, even if previous floaters seemed harmless
