Electroretinography (ERG)

Electroretinography is a crucial diagnostic tool for assessing retinal health, offering a detailed analysis of the retina's electrical activity. This test is comparable to an ECG for the heart, providing objective data that is vital for diagnosing both inherited and acquired retinal disorders. By capturing the retina's response to light, ERG plays a significant role in early detection and monitoring of retinal diseases.
Full-Field ERG (ffERG)

Full-field ERG evaluates the cumulative response of the entire retina by using a Ganzfeld bowl to provide uniform light stimulation. This method captures a comprehensive view of retinal health by measuring the summed electrical response, which consists of the a-wave, b-wave, and photopic negative response. The ffERG is invaluable for diagnosing and monitoring diseases like diabetic retinopathy and retinitis pigmentosa, offering insights into both rod and cone system functions.
Pattern ERG (PERG)

Pattern ERG focuses on the function of retinal ganglion cells by using an alternating checkerboard pattern to evoke responses. This specialized test is particularly useful for diagnosing conditions that affect ganglion cells, such as glaucoma and various neurodegenerative disorders. PERG enables clinicians to detect subtle changes in retinal function, providing critical information for early intervention and management of these conditions.
Multifocal ERG (mfERG)

Multifocal ERG provides a spatially resolved analysis of retinal function by using an array of flickering hexagons. This technique is particularly adept at identifying localized retinal dysfunctions, which is essential for diagnosing conditions like Stargardt’s Disease and Plaquenil toxicity. By mapping the function of different retinal regions, mfERG offers a detailed understanding of retinal health, aiding in precise diagnosis and treatment planning.
Visual Evoked Potential (VEP)

Visual Evoked Potential assesses the entire visual pathway from the retina to the visual cortex. By measuring the electrical activity in response to visual stimuli, VEP helps identify disruptions in visual information transmission. This test is crucial for understanding the integrity of the visual pathway, making it an important tool for detecting and diagnosing visual deficits.
