Retinal detachment: what the GP should look for

Retinal detachment is one of the better known ophthalmic problems. It is a reasonably common, and treatable, cause of visual loss. The diagnosis must be considered by GPs when patients present with the sudden onset of flashes, floaters and visual loss.

Key Points

Retinal detachment develops after the formation of a retinal break (tear), which allows fluid from the vitreous cavity to enter the subretinal space and the retina to detach from its normal position.
Posterior vitreous detachment causes most retinal tears.
The sudden onset of flashes, floaters, and peripheral visual field loss that progresses to loss of central vision requires same-day referral to an ophthalmologist.
Treatment of retinal detachment requires surgery, which has a high rate of success.
