71 Possible Causes for Full-Field Electroretinogram Normal, Severely Reduced Central Responses on Multifocal ERG

  • Occult Macular Dystrophy

    The multifocal ERGs 4 demonstrated a loss of local responses in the central retina (fig 2C).[bjo.bmj.com] […] fundus appearance, fluorescein angiogram and full-field electroretinogram.[readbyqxmd.com] full-field electroretinograms (ERGs) essentially normal.[ncbi.nlm.nih.gov]

  • Adult-Onset Foveomacular Vitelliform Dystrophy

    The electro-oculogram and full-field electroretinogram are typically normal, indicating localized retinal pathology.[unboundmedicine.com]

  • Occlusion of the Ophthalmic Artery

    Full field electroretinogram (ERG) of right (A) and left (B) eye shows extinguished scotopic and photopic responses. Fig. 2C shows ERG responses in normal eye.[ijmr.org.in]

  • Severe Idiopathic Pneumococcemia

    Full-field electroretinogram results were normal in 8 of 9 patients, although focal electroretinogram results were abnormal in 8 of 9 patients.[ncbi.nlm.nih.gov]

  • Vitreoretinochoroidopathy

    Full-field electroretinogram response amplitudes ranged from low normal (two cases; 27 and 32 years) to non-recordable (two cases; 42 and 63 years).[ncbi.nlm.nih.gov] Full field electroretinogram revealed normal Ophthalmic Genet Downloaded from informahealthcare.com by University of Otago on 07/07/15 For personal use only. 4 C. J.[docksci.com] At that time visual acuity was 20/25 in the right eye and 20/30 in the left eye, and full field electroretinograms revealed slightly subnormal photopic responses with single[docksci.com]

  • Primary Lateral Sclerosis

    A clinical evaluation and full field electroretinography according to International Society for Clinical Electrophysiology of Vision (ISCEV) standards was performed.[ncbi.nlm.nih.gov] Both siblings had reduced central vision without nystagmus and a normal fundus examination.[ncbi.nlm.nih.gov] The electroretinogram showed cone dysfunction with markedly reduced amplitude 30-Hz flicker, and broad, delayed photopic single flash of normal amplitude.[ncbi.nlm.nih.gov]

  • Chloroquine Retinopathy

    RESULTS: In one patient with mild chloroquine retinopathy the visual acuity, visual fields and full-field electroretinogram were normal, but retinal dysfunction was indicated[ncbi.nlm.nih.gov] Although, very few patients with mild chloroquine retinopathy may show normal visual acuity, visual fields and full-field electroretinogram, however, retinal dysfunction may[ispub.com] Two patients had full-field electroretinograms that showed no abnormalities and 6 showed evidence of generalized retinal dysfunction with reduced rod and cone responses.[doi.org]

  • Optic Atrophy

    International-standard full-field electroretinograms were normal in both individuals, with no evidence of generalized retinal dysfunction.[ncbi.nlm.nih.gov] Fundus examination revealed bilateral temporal optic nerve pallor in both patients with otherwise normal retinal findings.[ncbi.nlm.nih.gov]
