What is involuntary rapid eye movement in neonates known as?

In neonates, involuntary rapid eye movement is referred to as nystagmus. This condition is characterized by oscillating movements of the eyes that can occur in a variety of patterns. In the early stages of life, these movements may be observed as a normal developmental phenomenon. Nystagmus can be indicative of how the infant’s visual and neurological systems are maturing.

Strabismus, while also affecting eye movement, refers specifically to a misalignment of the eyes and does not describe rapid movements. Tachycardia relates to an increased heart rate, and blepharospasm is an involuntary closure of the eyelids, not associated with rapid eye movements. Understanding these distinctions helps in recognizing various eye movement disorders and their implications for visual development in infants.
