Patients with primary angle-closure glaucoma had no higher incidence of complications in the first year after either trabeculectomy or phacotrabeculectomy than patients with primary open-angle glaucoma, according to a study at a Singapore hospital.

"There is a clinical impression that glaucoma surgery for PACG is associated with greater risk of complications," according to the study authors, who noted that no study of postoperative complication rates between the two groups of patients had been conducted previously. "Many of the complications found were caused by specific problems usually unrelated to the underlying diagnoses."

The incidences of postoperative complications and reoperations were analyzed in the first year after glaucoma filtering surgery for PACG and POAG. The study examined 446 subjects with PACG and 816 subjects with POAG, finding no significant difference between the groups overall.

The authors said that both surgical techniques have been reportedly associated with postoperative complications such as endophthalmitis, shallow anterior chamber and hypotony, aqueous misdirection syndrome, choroidal detachment and vision loss.
