Argon laser prevents an eye condition from getting worse and sometimes helps to cure it. This procedure is aimed toward the preservation of central and color vision.
Argon blue-green laser (70% blue (488 nm) and 30% green(514nm)) Absorbed selectively at retinal pigment epithelial layer (RPE), hemoglobin pigments, choriocapillaries, inner and outer nuclear layer of the retina.
25 sie 2023 · This activity reviews the principles of lasers in ophthalmology while discussing the different types of laser mechanisms and examines the complications of laser therapy and safety steps to effectively use lasers in ophthalmology by an interprofessional team.
Some forms of glaucoma may also be treated with argon lasers. For instance, angle-closure glaucoma can be treated by using an argon laser to create a tiny hole in the iris (a capsulotomy), which allows excess fluid inside the eye to drain to reduce pressure.
Laser trabeculoplasty, both argon laser trabeculoplasty(ALT) and selective laser trabeculoplasty (SLT) types, is used to increase aqueous outflow facility through the trabecular meshwork (TM) in order to lower intraocular pressure (IOP) in cases of ocular hypertension and glaucoma.
The first continuous wave gas laser, a helium neon system, was demonstrated in 1961 and by 1967 a clinical argon laser was developed specifically for ophthalmic use, becoming
Photocoagulation: the laser beam is absorbed by a target tissue, this results in the rise of temperature that causes denaturation of proteins. Eg: Argon, Krypton, Diode (810), and Frequency-doubled ND: YAG laser.
