After placing the footplate on the cornea perpendicularly, the plunger moves in an amount depending on the IOP. Movement of the plunger is indirectly proportional to the IOP. WebIOP, medication use, and safety were assessed at each visit. Subject follow-up through Month 36 was completed. Results: Thirty-six eyes (92.3%; 95% confidence interval [CI] 79.1%, 98.4%) achieved the primary efficacy end point of Month 12 reduction in IOP ≥20% from baseline (unmedicated IOP) without ocular hypotensive medication.
WebThe standard for IOP measurement continues to be the GAT. Please explain how this device works and why it may not be the best way to measure IOP. The GAT belongs in the constant-area applanation family of tonometers. It works by flattening a defined area of the central cornea using a variable force. WebThe IOP readings by two instruments were significantly correlated with CCT in eyes with glaucoma (for the RBT, β=0.036 and P=0.002, and for the GAT, β=0.021 and P=0.033) but not in normal eyes. Conclusion: IOP readings measured using the RBT and GAT showed within the allowable range in the late elderly subjects with or without glaucoma.
