Laser photocoagulation is used in retinal detachment to seal retinal breaks.

• A. Cataract extraction
• B. Laser photocoagulation
• C. Panretinal photocoagulation
• D. Corneal crosslinking

Answer: (B)

Laser photocoagulation around retinal tears creates a controlled burn that leads to scarring and adhesion between the retina and the underlying choroid. This chorioretinal adhesion seals the edge of the tear, preventing vitreous fluid from seeping through and driving progression of a detachment. In retinal detachment repair, applying laser burns around the break forms a barricade that stops detachment from spreading. Other options don’t fit this specific use: cataract extraction is a lens surgery and doesn’t seal breaks in the retina; panretinal photocoagulation targets widespread retinal ischemia to reduce neovascularization, not to seal a single tear; corneal crosslinking strengthens the cornea, not the retina.
