Visual subject (facet-imaginative and prescient) testing is vital to make the analysis of RP and 網膜色素変性症 to document the diploma of peripheral imaginative and prescient loss. The electro-retinal examination (ERG) is a test that measures the electrical signals produced by the retinal cells when responding to light. The classic ERG pattern seen in RP exhibits a markedly diminished rod photoreceptor gentle-sensing response.


The Device for the evaluation of glaucoma services. The Software for the evaluation of refractive services. The Instrument for the assessment of rehabilitation services and methods. 5.
