Selective Laser Trabeculectomy
Selective laser trabeculoplasty (SLT) is a laser treatment for glaucoma that reduces intraocular pressure (IOP) by improving fluid drainage from the eye. It works by selectively targeting the pigmented cells in the trabecular meshwork, which are responsible for draining fluid out of the eye. This targeted approach minimizes damage to surrounding tissues.
Selective Laser Trabeculoplasty
How SLT Works:
Targeted Approach:
SLT uses short pulses of low-energy laser light to specifically target the melanin (pigment) in the trabecular meshwork cells.Improved Drainage:
The laser treatment stimulates the body's natural healing mechanisms, leading to the rebuilding of these cells and improved fluid drainage.Reduced IOP:
By improving fluid drainage, SLT lowers the pressure inside the eye, which can help slow or prevent vision loss in glaucoma patients.
Procedure:
Outpatient Procedure: SLT is typically performed in a doctor's office as an outpatient procedure.
Anesthesia: Eye drops are used to numb the eye before the procedure.
Laser Application: A special lens is placed on the eye to focus the laser light onto the trabecular meshwork.
No Pain: SLT is generally considered a painless procedure.
Short Recovery: Most patients experience little to no discomfort and can resume normal activities shortly after the procedure.
Benefits:
Effective IOP Reduction: SLT can effectively reduce IOP, potentially by 20-30%.
Reduced Medication Reliance: SLT can help reduce or eliminate the need for glaucoma medications.
Repeatable: SLT can be repeated if necessary, unlike some older laser treatments.
Safe: SLT is generally considered a safe procedure with minimal risks.
Potential Side Effects:
Temporary Discomfort:
Some patients may experience temporary discomfort, redness, or blurry vision after the procedure.Rare Serious Complications:
Serious complications are rare, but can include bleeding of the iris, swelling of the retina, or swelling of the cornea.
