Clinical Scorecard: Is There a Role for SLT After MIGS?
At a Glance
| Category | Detail |
|---|---|
| Condition | Primary Open-Angle Glaucoma (POAG) |
| Key Mechanisms | Selective laser trabeculoplasty (SLT) stimulates cytokine-mediated remodeling of the trabecular meshwork (TM) extracellular matrix to enhance aqueous outflow. |
| Target Population | Patients with mild to moderate POAG, particularly those who have undergone minimally invasive glaucoma surgery (MIGS). |
| Care Setting | Clinical decision-making framework for managing intraocular pressure post-MIGS. |
Key Highlights
- MIGS procedures lower intraocular pressure (IOP) but are not curative; IOP may rise after surgery.
- SLT is noninferior to first-line topical therapy and can be a viable option when MIGS efficacy wanes.
- The effectiveness of SLT depends on the preservation of functional TM tissue after MIGS.
- Retrospective studies indicate significant IOP reduction with SLT following certain MIGS procedures.
- Canaloplasty may be the most favorable MIGS category for preserving SLT target tissue.
Guideline-Based Recommendations
Diagnosis
- Monitor IOP in patients post-MIGS to identify rising pressure.
Management
- Consider SLT as a bridging intervention when IOP rises after MIGS.
Monitoring & Follow-up
- Evaluate the functional status of TM to determine SLT viability.
Risks
- Potential for progressive TM dysfunction and inadequate IOP control post-MIGS.
Patient & Prescribing Data
Patients with inadequately controlled POAG after MIGS.
SLT may reduce IOP by 2-3 mmHg and decrease the need for additional medical or surgical treatment.
Clinical Best Practices
- Assess TM preservation after MIGS to guide SLT candidacy.
- Utilize SLT in cases where IOP control is suboptimal following MIGS.
