Grafton Optical is pleased to announce Future Practice Hub CET session at 100% Optical 2018 - How useful are Ocular Response Analyzer measures ‘Corneal Hysteresis’ and ‘IOPcc’ in clinical practice?

November 24, 2017

The Ocular Response Analyzer® G3 (ORA) is the only device that measures Corneal Hysteresis (CH), which has been shown to be a superior predictor of glaucoma progression. The Grafton Optical session is being led by Anthony Khawaja, Consultant Ophthalmic Surgeon at Moorfields Eye Hospital.

 

Corneal Hysteresis is an indication of the biomechanical properties of the cornea, differing from thickness or topography which are geometrical attributes. This session will discuss the meaning of these measures and their clinical utility, considering published medical evidence.

 

Studies have shown CH measurements to be significantly and independently associated with glaucoma risk. Eyes with lower CH tend to progress more rapidly. Prospective longitudinal studies have demonstrated that baseline CH predicts the rate of future visual field loss in glaucoma suspects and patients. The biggest challenge in managing glaucoma is predicting future progression. It typically takes 5-6 visual field test results over a period of months or years to establish progression rates. Different glaucoma patients with similar risk factors may progress at dramatically different rates. This is unnerving to patients and clinicians alike. Ideally we would allocate resources to those who require it most.

 

Since CH has been shown to be more predictive of future visual field progression than other factors, including this parameter in assessment of glaucoma risk will improve glaucoma decision making and facilitate earlier intervention to improve visual outcomes.

 

In addition to Corneal Hysteresis, Ocular Response Analyzer G3 provides Corneal Compensated Intraocular Pressure (IOPcc), a better indication of the true pressure, proven to be less influenced by corneal properties than Goldmann or other methods of tonometry. This reading is also available in the Reichert 7CR Auto Tonometer which gives IOPcc as well as an IOPg reading.
