ERGs were recorded to red flashes (0.01-50 phcdsm(2)) presented against a steady background (2000 sctd) or 0-300 ms after its suppression. The cone a-wave was altered in form and increased in amplitude in the dark. Peak amplitudes were doubled when the dark period was 50-100 ms and also when it was 150-200 ms. Measurement of the a-wave at fixed times showed that amplitude increase occurred at t...

Purpose To describe the effect of rituximab on full-field electroretinography (ERG) in a patient with nonparaneoplastic autoimmune retinopathy (npAIR). Observations A 58-year-old male patient with visual complaints, positive anti-retinal antibodies and negative work-up for cancer was diagnosed with npAIR. Visual acuity and ancillary tests were normal except abnormal ERG in both eyes. The pati...

AIMS To describe the topography of multifocal electroretinograms (ERGs) and to explore its diagnostic value in patients with Stargardt's macular dystrophy (SMD). METHODS 51 patients with SMD were examined by means of the m-sequence technique to characterise the topography of electroretinographic responses in the central visual field. The results were compared with data from 30 normal voluntee...
