Abstract:
Retinal nerve fiber examination is confronted with the results of automatic exploration of visual field with Octopus. 99 eyes affected by open angle glaucoma were studied during a period of 4 years or less. Analysis is done in accordance with the course under therapy. Good pressure results are obtained. Meanwhile visual field indexes show a slow deterioration under medical treatment, a stabilisation after laser trabeculoplasty and a marked improvement after surgery (trabeculectomy). Retinal nerve fiber are clear prior affected in comparison with visual field in early glaucoma, and a perfect agreement is demonstrated in mature cases.
