Argon laser peripheral iridoplasty (Visulas 532s; Carl Zeiss Meditec, Germany) was performed under topical anesthesia using an Abraham lens (Ocular Instruments, Inc.) with a spot size that initially was set at 500 μm, with power (150–400 mW) and duration (0.4–0.5 seconds) titrated based on response. 18 Burns were aimed at the iris root ...
13 maj 2020 · Argon laser trabeculoplasty (ALT) was once the gold standard laser treatment for open-angle glaucoma (OAG), but it is poorly suited to repeat treatments because of significant coagulative damage and disruption to the trabecular meshwork architecture. 2, 3 Latina et al 4 first described
Long-term efficacy of 360° argon laser trabeculoplasty was studied in 118 eyes of 93 patients with uncontrolled chronic open-angle glaucoma. The mean intraocular pressure (IOP) decrease was 8.9 ± 5.4 mmHg (mean ± standard deviation [SD] in 71 eyes at 1 year, 9.3 ± 4.3 mmHg (mean ± SD) in 51 eyes at 3 years, and 10.3 ± 3.9 mmHg (mean ± SD ...
Conclusion: Argon laser trabeculoplasty is an effective means for reducing IOP in many patients followed for an extended time. However, up to one half of eyes within 5 years of ALT and two thirds of eyes within 10 years may require additional laser or surgical intervention for glaucoma control.
26 lip 2023 · In a study, Kanagaratnam and Ong 20 investigated the effects of selective laser trabeculoplasty (SLT) and ALRP on the corneal endothelial cells and found a decrease in corneal endothelial CD recovery at the first month, after SLT. They found a minor increase in polymegathism after ALRP but they concluded that neither SLT nor ALRP has a ...
To analyze reduction of intraocular pressure (IOP) by argon laser trabeculoplasty (ALT) in the Early Manifest Glaucoma Trial and factors influencing the effect of such treatment.
The 2019 Laser in Glaucoma and Ocular Hypertension (LiGHT) trial outlined the effectiveness of selective laser trabeculoplasty (SLT) in initial IOP control for open-angle glaucoma (OAG) and normal-tension glaucoma (NTG), in which laser therapy directed at pigmented trabecular meshwork (TM) cells modulates biological TM changes to increase ...
