Improve Glaucoma Management with the RETeval Handheld ERG Device

Visual field tests are subjective and sometimes hampered by cataracts and indeterminate results. Enter the handheld RETeval portable ERG testing device! An ERG uses light to assess the function of photoreceptors, bipolar, and ganglion cells in the eye. In particular, it measures what’s known as the photopic negative response. This response is specific to ganglion cells and can objectively reflect the presence and severity of glaucoma. Historically, ERG testing has been lengthy, difficult to perform, and often generated inconsistent results between tests, all of which have limited the clinical use of ERG. But with the RETeval system, ERG testing for glaucoma has significantly improved. The RETeval handheld device uses skin electrodes (no corneal contact), needs no dilation, and provides color-coded test results to comfortably evaluate ERG results. To address test-retest variability, the RETeval development team at LKC has recently developed a new algorithm that offers a significantly improved test-retest variability to objectively detect and monitor glaucoma patients. Research has shown that over time, ERGs can reveal subtle changes after starting medicine o reduce intraocular eye pressure, even if no other biomarker indicates improvement. Making ERG with the RETeval device a part of glaucoma management offers valuable information to the treatment decision process, even when media opacities are present. With new developments, ERG looks to become an increasingly relevant and useful tool in the challenging process of diagnosing glaucoma. Learn more at LKC.com
