1337 Visual evoked potential crossed asymmetry in the incomplete form of congenital stationary night blindness
Methods: OPs were recorded from a comeal lens, after Ganzfeld stimulation. The analog recording bandwidth was set to IO@1Khz. OPs were acquired following three difrerent protocols: 1) immediately after an abmot change in background illumination, 2) followina various time of preahaptation and 3) duhng the adaptation period. Purpose: The Visual Evoked Potential (VEP) crossed asymmetry revealed in...
متن کاملVisual evoked potentials with crossed asymmetry in incomplete congenital stationary night blindness.
PURPOSE To investigate a proposed postretinal defect in patients with the incomplete form of congenital stationary night blindness (CSNB2) and to compare visual evoked potential (VEP) results with those found in various forms of albinism. METHODS Visual evoked potentials were performed in 10 patients with a diagnosis of CSNB2, 10 subjects with albinism, and 17 normal subjects. Visual evoked p...
متن کاملCharacteristic ERG-flicker anomaly in incomplete congenital stationary night blindness.
Ten patients with the incomplete type of congenital stationary night blindness (CSNB) were examined with a 30 Hz flicker electroretinogram (ERG). After 30 min of dark adaptation, 30 Hz flicker ERG was recorded continuously for 12-15 min under white background illumination. All patients showed an exaggerated increase of amplitude and a universal characteristic change of wave shape as the light a...
متن کاملThe electroretinographic diagnosis of the incomplete form of congenital stationary night blindness
Fifteen patients with the incomplete form of congenital stationary night blindness (iCSNB) were reviewed to better characterize their electroretinographic (ERG) findings in view of differential diagnosis with other retinal conditions also presenting with negative bright-flash ERG responses. In all 15 patients, in dark-adapted conditions, the bright-flash ERG response had a normal a-wave followe...
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...
