Characteristics of Damage Produced by Non-Circular Retinal Laser Radiation.

摘要

A comparison of the appearance of retinal burns produced by slit laser radiation was made using the same optical apparatus for argon (514.5nm), neodymium (1060 nm), and ruby (694.3nm) lasers. The retinal changes produced by exposures to these slit images were elongated for laser exposures less than or equal to 12 ms. For longer exposure times, the retinal opacifications were circular in appearance. A partial explanation is presented based on the thermal conductivity of the retinal tissue. (Author)
