A Case Study of Infantile Nystagmus Syndrome (Congenital)
Journal of Case Reports in Medical Science, Volume 9, Issue 1,
Infantile nystagmus (IN), formerly known as congenital nystagmus, is an involuntary to-and-fro movement of the eyes that persists throughout life. IN is one of three types of early-onset nystagmus that first appear in infancy, alongside fusion maldevelopment nystagmus syndrome and spasmus nutans syndrome. Patients with acquired nystagmus may also be seen by optometrists. The features of IN overlap largely with those of fusion maldevelopment nystagmus syndrome, spasmus nutans syndrome, and acquired nystagmus, yet the management for each subtype is different. We report a case of bilateral congenital sensory nystagmus with bilateral megalocornea with left-sided relative afferent pupil defect with left eye global enlargement in ap axis with reduced caliber in left optic artery with pseudo polycorea with reduced visual acuity in the bilateral eye with buphthalmos with haab striae.
