Retinal detachment is a sight-threatening emergency in which the retina peels away from the back wall of the eye. Separated from its blood supply, the retina cannot function properly. Without prompt treatment, retinal detachment can cause permanent vision loss. The three types are rhegmatogenous (most common, caused by a retinal tear), tractional, and exudative.
Rhegmatogenous detachment occurs when a tear or hole allows fluid to collect beneath the retina. Tractional detachment results from scar tissue pulling the retina away (common in advanced diabetic retinopathy). Exudative detachment is caused by fluid accumulation without a tear, seen in inflammatory conditions.
For retinal tears without detachment, laser photocoagulation or cryotherapy seals the tear to prevent progression to full detachment.
Micro-incision vitrectomy removes vitreous traction, reattaches the retina, and uses gas or silicone oil tamponade to hold it in place.
A silicone band is sutured around the eye to indent the wall inward, closing the retinal break and supporting reattachment.
