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 ...
15 sie 2022 · In this case–control study, we measured visual acuity, objective refraction, ocular biometric parameters, and strabismus in premature cases classified according to the following categories: argon laser-treated retinopathy of prematurity (ROP), untreated spontaneously regressed ROP, no ROP, and full-term controls.
26 lip 2023 · The mechanism of argon laser retinal photocoagulation (ALRP) treatment is to apply thermal-induced retinal pigment epithelium damage. Light passes through the anterior optical segments of the eye to reach the retina.
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.
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 ...
Argon laser peripheral iridoplasty (ALPI) is a simple and effective means of opening an appositionally closed angle in situations in which laser iridotomy either cannot be performed or does not eliminate appositional angle closure because mechanisms other than pupillary block are present.
The Branch Vein Occlusion Study demonstrates that argon laser photocoagulation improves the visual outcome to a significant degree in eyes with branch vein occlusion and visual acuity reduced from macular edema to 20/40 or worse.
