Abstract
Since its introduction in 1973 by Beckmann et al., transscleral cyclophotocoagulation with the Nd:YAG laser has developed into a successful method in glaucoma therapy. It was initially performed with the aid of non-contact systems, whereby the laser beam was focused by means of a slit lamp. With the introduction of contact systems, for which purpose a number of different probes were employed, the treatment efficiency was found to be improved by a factor between 2 to 6. The transparency of the sclera increases as a function of the pressure exerted. Therefore, the pressure exerted by the contact probe is a critical factor in determining the transmission of laser radiation across the sclera and may in part explain the large differences which are reported in the literature with respect to the effectiveness of this treatment method.
