The authors describe physical and biological properties of a CO2 laser operating in the infrared area (wave length 10,600 m). The authors discuss the use of this laser in ophthalmology and draw attention to its advantages as well as shortcomings. They describe the apparatus 20-C of Pfizer Laser Systems, incl. safety measures required for operation of the CO2 laser.

Influence of antiglaucoma drugs on axonal transport in the optic nerve.

Tritiated leucine injected into the vitreous of experimental animals was used for detection of the dynamics of axonal transport in the optic nerve in eyes with elevated intraocular pressure (IOP). Direct quantitative evaluation of axonal transport was performed by means of the liquid scintillation counter. Our results show that topical instillation of beta-blockers, pilocarpine and epinephrine have the most positive influence on the dynamics of axonal transport in eyes with increased IOP. There was a zero or negative influence of physostigmine, neostigmine, echothiophate and partially of clonidine (isoglaucon).
