Nystagmus and Esotropia
Several types of nystagmus are associated with esotropia. Fusion maldevelopment nystagmus syndrome (also known as latent and manifest latent nystagmus) is a common feature of infantile esotropia. Ciancia syndrome (discussed earlier in this chapter) is a severe form of infantile esotropia associated with an abducting nystagmus. Nystagmus blockage syndrome occurs in children with congenital motor nystagmus, who use convergence to “damp,” or decrease the amplitude or frequency of, their nystagmus, resulting in esotropia. See also Chapter 13.
