Retinal detachment
Recognise retinal-detachment warning signs and why treatment is urgent.
Editorial publication · Medical review pending.
Understand
Retinal detachment occurs when the retina separates from the tissues that support and nourish it.
Possible symptoms
Flashes, a sudden appearance or increase of floaters, blurred vision and a dark shadow or curtain are warning signs.
Causes and associated factors
A tear related to age-related vitreous change is common; myopia, eye surgery, injury and family history increase risk.
Diagnosis
An urgent dilated eye examination looks for a retinal tear or detachment.
Tests
Retinal examination is central; eye ultrasound may be needed if the retina cannot be seen clearly.
Course of the condition
Without prompt treatment, detachment may spread and cause permanent sight loss.
Care options
Laser or freezing treats some tears; vitrectomy, scleral buckling or a gas bubble may reattach the retina.
When to consult
New flashes, many floaters, a curtain or visual loss require same-day eye assessment.
Urgent help
A dark curtain, spreading shadow or sudden sight loss is an immediate eye emergency.
