ACUTE ULTRASTRUCTURAL CHANGES OF THE TRABECULAR MESHWORK AFTER SELECTIVE LASER TRABECULOPLASTY AND LOW POWER ARGON LASER TRA- BECULOPLASTY

Purpose: To compare the histopathological changes in the human trabecular meshwork after low power argon laser trabeculoplasty (ALT) and selective laser trabeculoplasty (SLT) with a Q-switched, frequency-doubled, neodymium:yttrium-alumini-um-garnet (Nd:YAG) laser. Methods: In gonioscopically normal trabecular meshwork of three patients awaiting enucleation due to malignant melanoma of the choroid SLT and ALT were per-
