Trial Outcomes & Findings for Study of CyPass Implantation In Patients With Open Angle Glaucoma Refractory to Single or Multi-agent Topical Therapy (NCT NCT01166659)

NCT ID: NCT01166659

Last Updated: 2017-05-15

Results Overview

IOP (fluid pressure inside the eye) was assessed using Goldmann applanation tonometry and reported in millimeters mercury (mmHg). A reduction in IOP from baseline indicates an improvement. Proportion of eyes is reported as a percentage.

PRIMARY outcome

Timeframe: Baseline; Month 12 postoperative

Population: Eyes implanted with the CyPass 2FX device with data available.

IOP (fluid pressure inside the eye) was assessed using Goldmann applanation tonometry and reported in millimeters mercury (mmHg). A reduction in IOP from baseline indicates an improvement. Proportion of eyes is reported as a percentage.

Proportion of Eyes With Intraocular Pressure (IOP) Reduction of ≥ 20% at 12 Months Postoperatively Who Were on Fewer or the Same Number of Ocular Hypotensive Medications as Compared With Baseline
60.4 percentage of eyes

SECONDARY outcome

Timeframe: Month 12 postoperative

Population: Eyes implanted with the CyPass 2FX device with data available.

Target IOP was defined as ≥ 6 mmHg and ≤ 21 mmHg. Proportion of eyes is reported as a percentage.

Proportion of Eyes With Achievement of Target IOP With and Without Use of Ocular Hypotensive Medication
81.4 percentage of eyes

SECONDARY outcome

Timeframe: Baseline, Month 12 postoperative

Population: Eyes implanted with the CyPass 2FX device with data available.

The number of unique glaucoma medications was recorded. The mean number of topical IOP-lowering medications was computed by dividing the total number of medications used (the numerator) by the total number of subjects who reported on medication use at the visit.
