argon laser in ophthalmology

Argon ion Laser - Definition, Construction, Working and 3 Advantage and ..- argon laser in ophthalmology ,Before discussing Argon ion laser we have to know about ion laser because Argon ion laser is one of the types of ION LASER.. An ion laser is a gas laser in which ionized gas is used as the active or lasing medium.. The electrical pumping method is used to achieve the population inversion in an ion laser..Lasers in Ophthalmology - Optics and Photonics NewsThe fluorescence occurs under 488-nm light from an argon laser, and the confocal imaging technology excludes the fluorescence from the eye’s crystalline lens, which would otherwise mask the target signal from the retina.. The confocal scanning laser ophthalmoscope (SLO) creates an image of the retina by raster-scanning a narrow beam of light ..



Laser Trabeculoplasty: ALT vs SLT - EyeWiki

Argon laser trabeculoplasty (ALT) was introduced by Wise and Witter in 1979 for the treatment of medically uncontrolled glaucoma.. Soon after its introduction, the efficacy and safety of this new technique was studied in a large multicenter prospective clinical trial funded by NEI, Glaucoma Laser Trial (GLT), in which eyes receiving ALT 360 degrees were compared with timolol monotherapy..
