Use of a laser to treat diabetic retinopathy?

• A. Laser Photocoagulation
• B. Laser Photodisruption
• C. Laser Capsulotomy
• D. Photocoagulation

Answer: (A)

Laser photocoagulation is used to treat diabetic retinopathy because the laser selectively destroys ischemic retinal tissue and seals leaking vessels, which reduces edema and lowers the production of VEGF that drives new abnormal blood vessel growth. This helps prevent vision loss from neovascularization. The other terms describe different laser actions or entirely different eye procedures (photodisruption is a different laser mechanism, laser capsulotomy treats posterior capsule opacification after cataract surgery, and photocoagulation without specifying laser is too vague). So describing the treatment as laser photocoagulation best captures the standard approach for diabetic retinopathy.
