Selective Laser Trabeculoplasty (SLT) is a type of laser treatment used to lower intraocular pressure (IOP) in individuals with open-angle glaucoma. Glaucoma is a group of eye conditions characterized by damage to the optic nerve, often due to elevated IOP. SLT is a safe and effective option for managing glaucoma and reducing IOP.
Key points about SLT laser treatment:
Mechanism of Action: SLT uses a specialized laser to target specific cells in the trabecular meshwork, which is the drainage system of the eye responsible for regulating the outflow of aqueous humor (the fluid inside the eye). By applying laser energy to these cells, SLT helps improve the drainage of fluid, which can reduce IOP.
Selectivity: Unlike other laser treatments for glaucoma, SLT is considered "selective" because it targets only specific cells without causing significant damage to surrounding tissues. This makes SLT a repeatable treatment option if needed.
Procedure: SLT is typically performed in an ophthalmologist's office or an outpatient clinic. The patient sits at a laser machine, and a special lens is placed on the eye to help focus the laser precisely on the trabecular meshwork. The procedure usually takes about 5 to 10 minutes per eye.
Painless and Non-Invasive: SLT is generally painless, and patients may feel only a mild sensation during the procedure. No incisions or injections are required.
Post-Treatment: After SLT, patients may experience mild discomfort, blurred vision, or a foreign body sensation, but these symptoms usually resolve within a day or two. Eye drops may be prescribed to manage any discomfort and prevent inflammation.
Effectiveness: SLT can effectively lower IOP in many patients. The extent of IOP reduction can vary from person to person. Some individuals may achieve sufficient IOP control with SLT alone, while others may continue to require glaucoma medications or other treatments.
Suitability: SLT is most commonly used for open-angle glaucoma, which is the most common type of glaucoma. It may not be suitable for all cases or types of glaucoma.
Duration of Effect: The duration of IOP reduction from SLT can vary. Some individuals may experience a prolonged reduction in IOP, while others may require repeat treatments over time.
Consultation: If you have glaucoma or are concerned about your intraocular pressure, it's important to consult with an ophthalmologist. They can evaluate your condition, discuss treatment options (including SLT), and recommend the most appropriate approach for managing your glaucoma.
As with any medical procedure, individual experiences may vary, and it's important to follow your eye care professional's guidance and attend regular follow-up appointments to monitor the effectiveness of the treatment.
