[Chronic glaucoma treated by trabeculoretraction. Medium-term study of perimetric changes].

Authors use the Octopus 2000 automatic perimeter to study the evolution of visual field defects of 37 glaucomatous eyes treated by argon laser trabeculoplasty and followed up for one year. In a first time, half inferior laser trabeculoplasty is performed; half superior complement is done three months later if visual field defects improve. Various visual fields are compared by statistic delta program. Three months after trabeculoplasty more than 85% of visual field loss decrease or are stabilized. The same results are found after one year, without modification of initial medication.
