[Levobunolol HCl--a beta-blocker produced by the firm Allergan].

Vistagan is a new beta-blocker produced by Allergan that is used for treatment of glaucoma. The results of a clinical trial with 18 patients with open-angle glaucoma, previously treated with Timoptol, are presented. Vistagan was as effective as Timoptol in reducing the intraocular pressure and was better tolerated by patients.

[Laser microsurgery in glaucoma].

Based on ten years work, the authors summarize their experience with the use of different types of lasers and laser methods in the treatment of glaucomas. They draw attention to the limits of effectiveness of laser microsurgery, to different modifications of hitherto used methods and their combinations. The authors try to define the position of lasers in the therapy of glaucomas.

[A comparative study of various methods of measuring intraocular pressure].

The authors compare measurement of intraocular pressure by aplanation, impression and contact-free tonometry. They draw attention to the advantages of contact-free tonometry in screening of glaucoma which is a reliable, rapid and simple method.
