Manifest latent nystagmus (MLN) combined with esotropia may be confused with the nystagmus blockage syndrome (NBS), so the NBS may be overdiagnosed. The NBS is similar to MLN in the characteristics of the nystagmus and the clinical features, thus two diseases must be differentiated. In order to differentiate the MLN with esotropia from the NBS, accurate calibration of slow phase of nystagmus is essential with the aid of electro-oculography (EOG). With EOG recording, authors report a case of MLN associated with esotropia which may be misdiagnosed as the NBS.
Key Words: Esotropia;Electro-oculography;Manifest latent nystagmus;Nystagmus blockage syndrome
