Retinal tears can usually be treated when detected with laser retinopexy. The laser creates a chorioretinal scar, often described as a “spot weld”, around the tear. Once this heals (often within about 48 hours), the retina is much less likely to detach beyond the treated barrier. This is highly effective at preventing a retinal detachment, which would otherwise require surgery and carries a greater risk.

Retinal laser treatment for tears is generally low risk, and because the treated area is typically in the peripheral retina (outside the central vision), it usually does not affect central visual clarity. Retinal tears are thought to occur during age-related changes in the vitreous gel as it becomes more liquid and separates from the retina. In areas where the vitreous remains more adherent to the peripheral retina, traction can create a tear.

When patients develop new symptoms such as flashes, floaters, or a curtain/shadow in vision, they may have a retinal tear and should be evaluated urgently by a retinal specialist. Untreated tears can allow fluid to enter beneath the retina (the subretinal space), significantly increasing the risk of retinal detachment.
