ABSTRACT In a prospective randomized study on primary argon laser trabeculoplasty vs piloparpine in 82 newly detected open-angle glaucoma patients, visual field changes were analysed for absolute changes over 2 years on automated threshold perimetry and manual Goldmann perimetry. Regression analysis was also performed using the threshold perimetry examinations taken every second month. Analyses based on automatic perimetry were corrected for eventual bias due to cataract and induced miosis. There was significantly less decay of visual field in the group treated with laser. This was even more pronounced for eyes with capsular glaucoma, especially in the early stage. For the smaller group with simple glaucoma no significant advantage of laser could be shown. Successful intraocular pressure reduction significantly improved the visual field outcome. Laser trabeculoplasty is therefore recommended as primary therapy in capsular glaucoma.
