It is a laser system that uses noble gas as an active medium. Argon laser has been applied as a therapeutic agent in ophthalmology for more than 50 years.
How does Argon laser work?
A device emits wavelengths of blue, red, yellow, or green light, which is a monochromatic source. Each beam has a very narrow range. In ophthalmology, argon laser is mostly applied to retinal diseases as well as glaucoma.
- Retinal tear
- Diabetic retinopathy
- Retinal vein occlusion
- “Extrafoveal” choroidal neovascularization
- Various other vascular diseases of the retina such as Coats disease, Eales etc.
Treatment with Argon laser
The laser light beam penetrates the anterior tissues without causing them damage. Focusing on the posterior pole of the retina essentially causes a mild reaction to avoid retinal detachment, bleeding in the vitreous, neovascular glaucoma, etc. The result of laser treatment is permanent. Usually only one session is required if it is a retinal crack and up to 3-4 sessions if it is severe diabetic retinopathy or other vascular disease.
How is Argon laser performed?
Treatment is carried out with administration of only anesthetic drops, in a seated position. Its duration rarely exceeds 10 minutes. After treatment usually it is not necessary for the patient to take any treatment or protective measures.
