# What causes veiled vision?

Veiled vision suggests a curtain, veil, or film partly obscuring sight. It can indicate retinal detachment or opacities in the cornea, lens, or vitreous.

## Serious Causes

A descending grey curtain or shadow is a classic symptom of retinal detachment, often preceded by flashes and floaters. Dense vitreous haemorrhage or inflammatory haze can also create a veiling effect across the field.

- Retinal detachment is an emergency that can permanently impair vision
- Corneal scars or advanced cataracts may cause more static veiling
- Transient veils might arise from migraine aura or transient ischemia
- Symptoms may be monocular even when perceived as in front of both eyes

## Urgent Evaluation

Any new veil, especially with light flashes, floaters, or field loss, requires prompt dilated retinal examination. Imaging clarifies the extent of detachment or opacity.

- Early surgery for detachment offers the best chance of visual recovery
- Systemic causes of vascular events should be investigated in haemorrhagic veils
- Long-standing veils from cataract or scars may be addressed electively
- Patients should avoid driving until the cause is clarified
