What does SLT stand for in glaucoma therapy?

• A. Selective Laser Trabeculoplasty
• B. Simple Laser Therapy
• C. Subconjunctival Laser Treatment
• D. Scleral Laser Therapy

Answer: (A)

The concept being tested is recognizing the glaucoma laser therapy used to lower eye pressure by improving fluid drainage. SLT stands for selective laser trabeculoplasty. In this procedure, a laser is aimed at the trabecular meshwork in the eye, and the energy is absorbed mainly by pigmented cells. This selective photothermolysis creates microchanges in the outflow pathway that reduce resistance and allow aqueous humor to drain more easily, lowering intraocular pressure. The approach is gentler than older laser methods because it minimizes damage to surrounding tissue, and the treatment can be repeated if needed. It’s commonly used as an initial option or in combination with medications to control glaucoma. The other terms listed don’t describe this standard glaucoma laser therapy.
