SLT

Definition

SLT, or Selective Laser Trabeculoplasty, is a minimally invasive laser procedure used to treat glaucoma by lowering intraocular pressure. It works by using a laser to selectively target and treat specific cells within the trabecular meshwork, enhancing the outflow of aqueous humor. This targeted approach minimizes damage to surrounding tissues and can result in effective pressure reduction with fewer side effects compared to traditional surgical methods.

5 Must Know Facts For Your Next Test

1. SLT is particularly beneficial for patients with open-angle glaucoma as it offers a non-invasive option for lowering eye pressure.
2. The procedure is typically performed in an outpatient setting and usually takes only about 15-20 minutes.
3. Post-operative recovery from SLT is generally quick, with many patients experiencing improved intraocular pressure shortly after the treatment.
4. Unlike traditional trabeculectomy surgeries, SLT does not create a bleb and has a lower risk of complications.
5. Patients may still need medication post-SLT to maintain optimal intraocular pressure levels, but many can reduce their reliance on eye drops after treatment.

Review Questions

• How does SLT specifically target the trabecular meshwork to lower intraocular pressure?
  • SLT specifically targets the trabecular meshwork by using a laser to selectively treat certain cells within this structure. This treatment helps to enhance the outflow of aqueous humor from the eye, thus lowering intraocular pressure. By focusing on specific cells without damaging surrounding tissues, SLT allows for effective pressure reduction while minimizing complications associated with more invasive procedures.
• Compare and contrast SLT with traditional glaucoma surgeries in terms of patient outcomes and risks.
  • SLT offers several advantages over traditional glaucoma surgeries, such as trabeculectomy. While both aim to lower intraocular pressure, SLT is less invasive and typically has a quicker recovery time. Additionally, SLT generally has a lower risk of serious complications like infection or scarring. However, some patients may still require medication after SLT, whereas traditional surgeries might provide longer-lasting results but at the cost of higher risks.
• Evaluate the impact of SLT on long-term management strategies for patients with glaucoma and how it alters their treatment pathways.
  • SLT has significantly impacted long-term management strategies for glaucoma by providing an effective alternative to medications and more invasive surgeries. Many patients can achieve lower intraocular pressures post-treatment, allowing them to reduce their dependence on topical medications. This change in treatment pathway not only enhances patient compliance due to fewer eye drops but also leads to better overall management of glaucoma with fewer side effects. As a result, SLT has become an integral part of glaucoma treatment protocols.
