Previous cyclodestructive surgery was associated with an increased risk of suprachoroidal hemorrhage and late-onset postoperative hypotony after glaucoma drainage device surgery, a study found.

Investigators retrospectively analyzed 110 patients who underwent glaucoma drainage device implantation and were followed for at least 3 months; 47 patients underwent previous cyclodestruction surgery (group 1), and 63 patients had not (group 2).

Mean preoperative IOP was 32.1 mm Hg in group 1 and 29.2 mm Hg in group 2. Mean medication use was 4.8 in group 1 and 4.9 in group 2.

Six cases of postoperative suprachoroidal hemorrhage appeared in group 1 and none appeared in group 2; the between-group difference was statistically significant, according to the investigators (P < .01).

Nine patients in group 1 and three in group 2 developed late-onset hypotony more than 6 weeks after glaucoma drainage device surgery (P = .03).
