ALT is for those: who have been diagnosed with glaucoma Argon laser lash ablation can be done as an effective office procedure with topical anesthesia. The advantages include low recurrence and complication rates in carefully selected patients and minimal postoperative discomfort. 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.

What is an argon laser

It is high gain system. Argon laser has very less divergence (about 1 milli radian) like He-Ne laser. Drawbacks or disadvantages of Argon Laser The Argon laser is a laser system that uses noble gas as the active medium. Argon gas lasers are used in many applications such as forensic medicine, entertainment, general surgery, ophthalmic surgery, holography and as an optical “pumping” source. Argon laser is a common laser used for treating DR. The main spectral peaks of the argon laser are 488 nm (blue) and 514 nm (green) i.e. relatively shorter wavelengths.

The core component of an argon ion laser is an argon-filled tube, made e.g. of beryllium oxide Laser Resonator. The laser resonator is normally a simple two- mirror resonator, little longer than the laser tube. The Typical Output Power and Power The argon laser is a special, green-wavelength laser that is often used for retinal therapy.

This laser was invented in 1964 and was designed to emit a blue/green colored light which is absorbed by hemoglobin in the blood cells. The heat allows the laser to close off ruptured blood cells.

This laser was invented in 1964 and was designed to emit a blue/green colored light which is absorbed by hemoglobin in the blood cells. The heat allows the laser to close off ruptured blood cells. An argon laser is a device that uses argon gas and produces a beam of light with a wavelength that is absorbed only by specific pigments such as hemoglobin and melanin, and passes harmlessly through other materials such as fluids. The Argon laser is a unique laser system, as it uses a noble gas as the active medium. This laser was invented in 1964 and was designed to emit a blue/green colored light which is absorbed by hemoglobin in the blood cells. The argon laser active medium consists of this gas, where the lasing takes place due to ions of argon gas. That is why argon laser is the most popular type of ion lasers.
