The Claim
Washed-out intraocular pressure metrics (WO-MIOP and WO-PIOP) are more strongly associated with visual field progression than standard mean IOP in patients with glaucoma.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
Measuring eye pressure after filtering out short-term fluctuations better predicts long-term vision loss in glaucoma than standard eye pressure readings.
See the scientific wording
Washed-out intraocular pressure metrics (WO-MIOP and WO-PIOP) are more strongly associated with visual field progression than standard mean IOP, suggesting that filtering out transient pressure fluctuations reveals a more accurate predictor of long-term glaucoma damage.
When eye pressure spikes briefly, they don't harm the optic nerve, but the steady pressure between spikes slowly crushes the nerve fibers over time. Removing the spikes shows the real pressure that damages vision.
What the research says
1 studyStudy: Effect of intraocular pressure control on visual field progression in the HORIZON trial.
When doctors ignore short-term spikes in eye pressure and just look at the steady average, they can better predict which patients will lose vision over time — better than using the regular average pressure that includes those spikes.
