研究目的
To review the studies available on the repeatability of selective laser trabeculoplasty (SLT) in treating open-angle glaucoma (OAG) and ocular hypertension (OHT), and to conclude its efficacy, success rate, duration, and complications compared to initial SLT.
研究成果
Repeat SLT has comparable efficacy and low complication rates to initial SLT, and should be encouraged if primary SLT is unsuccessful or its effects subside.
研究不足
The matter of SLT repeatability remains controversial and requires further corroborations. Maximal SLT repeatability and its impact on filtration surgery or other treatment methods is yet to be resolved.
1：Experimental Design and Method Selection:
The review systematically analyzed previously conducted studies on SLT repeatability.
2：Sample Selection and Data Sources:
Studies included patients with OAG and OHT who underwent initial and repeat SLT.
3：List of Experimental Equipment and Materials:
SLT was performed using a 532 nm, frequency-doubled, Q-switched neodymium-doped yttrium aluminium garnet (Nd:YAG) laser.
4：Experimental Procedures and Operational Workflow:
SLT was performed with 40–50 shots over 360°. Success was defined as ≥20% IOP reduction.
5：0°. Success was defined as ≥20% IOP reduction. Data Analysis Methods:
5. Data Analysis Methods: The efficacy, success rate, duration, and complications of repeat SLT were compared to initial SLT.
