Atropine after trabeculectomy.

Thirty-eight patients requiring trabeculectomy for control of open-angle glaucoma were randomized into two groups. One group received topical atropine immediately after trabeculectomy; the second group began treatment on the first postoperative day. The two groups were compared over the first three postoperative days. The theoretic benefit of atropine instillation immediately after trabeculectomy is discussed. Our results showed no significant difference between the two groups except there was a significantly larger pupil diameter in the treated group on the first postoperative day.
