Undetectable S cone electroretinogram b-wave in complete congenital stationary night blindness.
AIMS The short wavelength sensitive (S) cone electroretinograms (ERGs) were examined in two patients with the complete type of congenital stationary night blindness (CSNB). METHODS Ganzfeld spectral flashes in the presence of strong white adapting fields were used to elicit the S cone ERGs. RESULTS The S cone ERG b-wave was not detectable to short wavelength stimuli, while the mixed long (L...
متن کاملThe photopic electroretinogram in congenital stationary night blindness with myopia.
Previous studies have reported that subjects affected with congenital stationary night blindness and myopia demonstrated some photopic (cone) abnormalities in their electroretinogram (ERG). By comparing the photopic ERG elicited with a threshold and a suprathreshold stimulus it was found that, at threshold, no significant differences were noted both in the peak time and in the amplitude of ERGs...
متن کاملMultifocal ERG findings in complete type congenital stationary night blindness.
PURPOSE To study the multifocal electroretinogram (mfERG) in patients with the complete type of congenital stationary night blindness (cCSNB), which is thought to be due to a defect in neurotransmission from the photoreceptors to the ON-bipolar cells. METHODS mfERGs were recorded with the VERIS recording system from four patients with cCSNB, none of whom had nystagmus. The stimulus array cons...
متن کاملCongenital Stationary Night Blindness Panel
Test code: OP1201 The Blueprint Genetics Congenital Stationary Night Blindness Panel is a 17 gene test for genetic diagnostics of patients with clinical suspicion of congenital stationary night blindness. The panel covers genes associated with autosomal recessive, autosomal dominant and X-linked forms of congenital stationary night blindness (CSNB). The clinical utility of this diagnostic panel...
