Argon LASER Absorption Test to the Skin

Laser propagation and energy absorption by an argon spark

The laser propagation and energy absorption of an argon spark induced by a laser at different pressures is investigated. 8 ns pulses from a frequency-doubled Q-switched Nd:YAG laser are used to create the spark. The pressure of the argon is varied from 1 atm to 10 Torr. Significant energy absorption by the plasma is observed at high pressures (.100 Torr) while there is negligible absorption whe...

Argon laser iridotomy.

Argon laser iridotomy was successfully performed on 47 out of 52 eyes of 35 patients by the continuous wave argon laser. The technique of argon laser iridotomy is described in detail. A number of complications were observed. The reasons for these are discussed, and measures for the avoidance of complications are suggested.

Binocular indirect argon laser photocoagulator.

The binocular indirect argon laser photocoagulator was newly designed to enable visualisation of the entire fundus during panretinal laser photocoagulation and to treat retinal tears immediately after buckling procedures of the sclera. The lamp housing of the binocular ophthalmoscope was remodelled and adjusted so that the laser beam and illuminating light are coaxial after leaving the ophthalm...

Common Blepharitis Related to Phthiriasis Palpebrarum: Argon Laser Phototherapy.

A 42-year-old woman was admitted to Mersin University, Department of Ophthalmology Clinic with itching and burning sensation of the right eye for 3 weeks. In her slit-lamp examination, nits and lice, attached to the upper and lower eyelashes of her right eye, were observed. Lice and nits were destroyed by argon laser phototherapy and were removed with the help of a fine forceps thereafter. Argo...
