Nonsignificant IOP change detected in certain open-angle glaucoma patients after phaco
In patients with open-angle glaucoma who had severe visual field loss and/or uncontrolled or marginally controlled glaucoma, the IOP change after phacoemulsification was nonsignificant, according to a study.
The retrospective case series evaluated 56 eyes that had severe vision loss and/or IOP of 21 mm Hg or higher on three or more topical drugs for IOP control.
At 1 day after phaco, 12 eyes had an IOP spike of 50% or greater from baseline. A spike of 30 mm Hg or greater was detected in five eyes, an increase of 10 mm Hg or greater was found in 10 eyes, and a spike of 5 mm Hg or greater was detected in 18 eyes.
In a subgroup of 45 patients who had 1-year postoperative follow-up, 27 eyes had uncontrolled or marginally controlled glaucoma and 18 had severe visual field loss. The average IOP in the subgroup decreased from 14.3 ± 3.5 mm Hg to 13.8 ± 3.6 mm Hg after the first year. Eleven eyes had an IOP increase of 3 mm Hg or greater, while 14 eyes had a decrease of 3 mm Hg or greater.
Three patients underwent trabeculectomy within the first year and were not included in the 1-year postoperative analysis.
“In our study, the only identifiable risk factors for worse IOP control at 1 year in the uncontrolled or marginally controlled OAG subgroup analysis were younger age and sustained increase in IOP [of] 10 mm Hg [or greater] at [postoperative week 1],” the study authors said. – by Rebecca L. Forand
