Which part of the eye is targeted by laser trabeculoplasty?

• A. Ciliary body
• B. Lens
• C. Trabecular meshwork
• D. Retina

Answer: (C)

Laser trabeculoplasty targets the trabecular meshwork, the drainage pathway for aqueous humor in the anterior chamber. Applying laser energy to this tissue changes its structure and increases outflow through Schlemm’s canal, which lowers intraocular pressure—especially helpful in open-angle glaucoma. The ciliary body is the source of aqueous production, not the drainage route; substances that reduce production target the ciliary processes, not the meshwork. The lens and retina aren’t involved in the outflow pathway affected by this procedure.
