[Changes in the visual fields following filtering surgery in advanced glaucoma]. / Modification du champ visuel au décours des interventions filtrantes dans les glaucomes évolués.

The authors report about the results of a preliminary study concerning the changes of glaucomatous field after glaucoma filtering surgery in patients with advanced glaucoma. Mesopic campimetry had been selected because of its precision for central field defects. The first results appear to be favourable. No patient lost central vision suddenly after surgery. The authors have tried to research predictive risk factors. The factors that seem to be the most important to consider are the preoperative campimetric shape and the angle anatomy.

[Early postoperative campimetric outcome after trabecular surgery of chronic advanced glaucoma]. / Evolution campimétrique post-opératoire précoce après chirurgie filtrante dans les glaucomes chroniques évolués.

The authors report about the results of a preliminary study concerning the changes of glaucomatous visual field just after glaucoma filtering surgery in patients with advanced glaucoma. The visual field was established preoperatively, then 7 and 30 days in post operative period. Mesopic campimetry had been selected because of its precision for central field defects. The results appear to be favourable with 13 improvements 14 stabilizations, and 7 aggravations without loss of central vision. The authors have tried to determine predictive risk factors. The most important one are preoperative campimetric shape, angle anatomy, refraction and cardiovascular diseases.
