DEVICE FOR ERG (ELECTRO-RETINOGRAM)
SPECTRAL PERIMETRY
Introduction: The invention comprises an apparatus and method for eye examination. This device will measure the electrical response of the human retina to lights of different colors and spatial frequencies at controllable retinal loci with sufficiently small yet intense stimuli to provide a fine grain map of localized changes in function.
The invention features a three path Maxwellian view optical system by which a stimulus test pattern may be ophthalmoscopically placed on small portions of the central 70? of the retina of an eye. The location of the stimulus test target on the retina may be tracked and recorded by a spectral perimetry system. The invention further provides a spectral sensitivity measurement system in which electroretinogram (ERG) data is collected, transmitted, processed, and displayed or stored.
This will be a useful, general purpose, diagnostic device for early detection and differential diagnosis of various disorders such as retinitis pigmentosa, the cone-rod dystrophies, glaucoma, diabetic retinopathy, retinal detachment and optic atrophy.
