Which Conditions Are You Interested In?
Diabetic Retinopathy
Diabetic Retinopathy is the most common cause of vision loss and blindness for people with diabetes as high blood sugar levels can damage blood vessels in the retina.
Tests: Multifocal ERG, Flash and Flicker ERG
Diagnosys Stimulators: LCD Monitor and Envoy (mfERG); ColorDome, ColorFlash and ColorBurst (Flash and Flicker)
Glaucoma
Glaucoma is a group of eye diseases that may lead to vision loss, characterized by retinal ganglion cell damage while bipolar cells and photoreceptors remain nearly normal.
Tests: PERG, PhNR
Diagnosys Stimulators: Envoy (PERG); ColorDome, ColorBurst and ColorFlash (PhNR)
Inherited Retinal Diseases (IRD)
Inherited retinal diseases (IRDs) are caused by different gene mutations that can cause vision loss due to dysfunction primarily of the photoreceptors. Some of the more common IRDs are retinitis pigmentosa, Stargardt disease, Leber congenital amaurosis, and achromatopsia.
Tests: ffERG, mfERG, PERG, PhNR, EOG, EER, FST, DA, pupillometry
Diagnosys Stimulators: ColorDome (ffERG, PhNR, EOG, FST, DA, pupillometry); ColorFlash (ERG, PhNR, FST, DA); ColorBurst (ffERG, PhNR); LCD monitor (mfERG); Envoy (mfERG, PERG); EER module (EER)
Neurological Conditions
Neurological conditions may affect the visual pathway from the optic nerve head to the visual cortex resulting in vision loss or even blindness. These conditions include autism, bipolar disorder, brain tumors, idiopathic intracranial hypertension, non-organic vision loss, optic neuritis, schizophrenia, and traumatic brain injury.
Tests: ffERG, mfERG, PERG, PhNR, VEP, sweep VEP, pupillometry
Diagnosys Stimulators: ColorDome (ffERG, PhNR, fVEP, pupillometry); ColorFlash and ColorBurst (ERG, fVEP, PhNR); LCD Monitor (mfERG, sweep VEP, pVEP); Envoy (PERG, pVEP)
Pediatric
Pediatric disorders may cause vision loss or blindness in children due to retinal, visual pathway, or cortical pathology. These conditions include albinism, chiasmal dysfunction, cerebral visual impairment, retinal toxicity due to epilepsy medications, retinoblastoma, retinopathy of prematurity, and IRDs in infants and children.
Tests: ffERG, mfERG, PERG, sweep VEP, EOG, fVEP, pVEP
Diagnosys Stimulators: ColorDome (ffERG, EOG, fVEP); ColorFlash and ColorBurst (ERG, fVEP); Envoy (PERG, pVEP); LCD Monitor (sweep VEP, pVEP, mfERG)
Toxicity
Toxicity: Over time, the usage of certain medications may lead to vision loss because they can be toxic to the macula, retina, or optic nerves.
Tests: Multifocal ERG
Diagnosys Stimulators: LCD Monitor, Envoy
