SAN FRANCISCO — A technique dubbed the purse-string suture seems to be an effective surgical intervention in the treatment of neovascular glaucoma, according to a poster presentation here at the American Society of Cataract and Refractive Surgery meeting.

Wan-Soo Kim, MD, and colleagues retrospectively reviewed six eyes of six patients who had an incidence of IOP spikes between 42 mm Hg and 60 mm Hg during the course of their neovascular glaucoma. The patients were unresponsive to medical and laser treatment. The patients’ visual acuity ranged from finger counting to 30/200. They had closing angles and neovascularization of the angle was noted. All eyes underwent purse-string sutures with a PC-7 needle, Dr. Kim noted.

IOP was stabilized within 2 weeks; stabilization in these cases was defined as 22 mm Hg or less. Anterior chamber angles were open after surgery; hyphema was noted in all cases.
