Two brothers are described with a similar physical appearance characterised by minor periorbital anomalies, malar flatness, a maxillary overbite, retrognathia, sloping shoulders, joint hyperextensibility, and minor radiological anomalies. In addition, they had a slowly progressing night blindness, myopia, and extinguished electroretinograms. The mother had mild expression of some of the physica...

We have recorded ocular potentials in response to brief flashes of light from two teleosts, the white perch (Roccus americana) and the green sunfish (Lepomis cyanellus). The animals were respired and maintained in an alert state for up to 2 d. Responses were recorded with corneal and transcleral electrodes. The responses of green sunfish were composed of electroretinogram (ERG) and eye movement...

PURPOSE To investigate the usefulness of second-order multifocal electroretinograms (MERGs) for detecting inner retinal disorders. METHODS The MERG from 5 patients with branch retinal artery occlusion (BRAO) was recorded. Twelve eyes of 12 normal subjects were also tested. MERGs were recorded using 61 hexagons. Bright flash ERGs were also recorded to measure the oscillatory potentials (OP). R...

BACKGROUND It is generally stated that opacities of the ocular media, including senile cataract, have little effect on the electrical responses of the retina. However, lower amplitudes and longer implicit times are sometimes observed in electroretinograms (ERGs) of patients with mature cataract. METHODS Single flash ERGs of mature cataractous eyes with decimal visual acuity less than 0.1 were...

PURPOSE To explore a possible association between full-field electroretinograms with vitreomacular adhesion resolution and best-corrected visual acuity as part of the prospective, randomized, double-masked, sham-controlled Ocriplasmin for Treatment for Symptomatic Vitreomacular Adhesion Including Macular Hole (OASIS) trial studying ocriplasmin. METHODS The ERG substudy enrolled 62 of 220 OASI...
