Diurnal IOP fluctuations controlled by trabeculectomy, sinusotomy
Combined trabeculectomy and sinusotomy dampened diurnal IOP fluctuations in eyes with primary open-angle glaucoma, according to a study.
The study included 14 eyes of eight patients with open-angle glaucoma who had large diurnal IOP fluctuations but low IOP during regular office hours. All patients underwent combined trabeculectomy and sinusotomy.
Mean IOP decreased from 16.5 mm Hg preoperatively to 13.9 mm Hg postoperatively. The change was statistically significant (P = .00064).
The maximum IOP decreased from 21.9 mm Hg preoperatively to 16.1 mm Hg postoperatively, which was also statistically significant (P = .0020).
Complications included one case of Descemet's membrane detachment and two cases of transient IOP elevation. No common postoperative trabeculectomy complications were reported.
