Cole Eye Institute Outcomes
Glaucoma Surgery Outcomes
Change in IOP at 3- to 12-Month Follow-Up (N = 482)
Trab = trabeculectomy, CPC = cyclophotocoagulation + micropulse, GATT = gonioscopy-assisted transluminal trabeculectomy, IOP = intraocular pressure
ᵃHydrus was combined with phacoemulsification
In patients treated at the institute during 2021, trabeculectomy reduced IOP from a mean of 24.83 mm Hg to 15.78 mm Hg, glaucoma implant surgery reduced IOP from a mean of 26.11 mm Hg to 17.65 mm Hg, and cyclophotocoagulation reduced IOP from 33.07 mm Hg to 24.33 mm Hg. For the newer procedures, goniotomy reduced IOP from 17.94 mm Hg to 15.88 mm Hg, and GATT reduced IOP from 23.57 mm Hg to 13.74 mm Hg. The two newer procedures whose outcomes have been tracked for the past 2 years showed a reduction in mean IOP from 15.74 mm Hg to 13.76 mm Hg (hydrus); and 19.62 mm Hg to 11.89 mm Hg (Xen G). A normal range of IOP is approximately 10 mm Hg to 21 mm Hg. N = number of patients who returned for a follow-up visit and had IOP measured.
