6 Possible Causes for Electroretinography Responses Normal or Decreased

  • Best Disease

    Best disease, also known as Best vitelliform macular dystrophy, is a rare genetic disease in which progressive macular degeneration leads to variable symptoms of impaired vision and visual acuity. The use of specialized ophthalmologic procedures, as well as genetic testing, is necessary to confirm the diagnosis. Best[…][symptoma.com]

  • Pancreatic Adenocarcinoma

    Initial testing showed significantly reduced scotopic rod responses in both eyes and decreased vitamin A levels and a normal cancer-associated retinopathy laboratory panel[ncbi.nlm.nih.gov] He had complete recovery of both his symptoms and full-field electroretinography within 5 days of starting intramuscular vitamin A.[ncbi.nlm.nih.gov]

  • Occult Macular Dystrophy

  • Homocystinuria

    Electroretinography was performed in 6 of the 9 patients, three of whom showed decreased scotopic and photopic responses.[ncbi.nlm.nih.gov] The other three patients had normal responses on electroretinography. CONCLUSIONS: Ocular findings in patients with cblC are variable.[ncbi.nlm.nih.gov]

  • Vitamin A Deficiency

    Initial testing showed significantly reduced scotopic rod responses in both eyes and decreased vitamin A levels and a normal cancer-associated retinopathy laboratory panel[ncbi.nlm.nih.gov] The scotopic bright flash, or maximal combined response, was decreased in both eyes with a value of 165 microvolts OD and 95 microvolts OS (normal range is 255.4 microvolts[webeye.ophth.uiowa.edu] He had complete recovery of both his symptoms and full-field electroretinography within 5 days of starting intramuscular vitamin A.[ncbi.nlm.nih.gov]

  • Oguchi Disease

    The scotopic bright flash, or maximal combined response, was decreased in both eyes with a value of 165 microvolts OD and 95 microvolts OS (normal range is 255.4 microvolts[webeye.ophth.uiowa.edu] The right eye had a nearly normal visual field (Figure 2).
