![]() CSNB is interesting to study because through electrophysiological findings, it enables a better understanding of the physiology of neural transmission in the outer part of the retina.Keywords: Congenital nystagmus, negative electroretinography, congenital night stationary blindnessĪllelic variation of the FRMD7 gene in congenital idiopathic nystagmus. This diagnosis was confirmed by genetic studies. The first results showed electronegative electroretinography in the two cases and examination combined with electroretinographic findings helped us to make the diagnosis of Congenital Night Stationary Blindness (CSNB. Clinical and electrophysiological protocols were detailed. This case report presents two male patients with congenital nystagmus examined longitudinally from the age of six months until 17-18 years of age. The precise diagnosis requires detailed clinical examination and electrophysiological findings.
