Definitions from the Web

Pathological Nystagmus

Description

Pathological nystagmus refers to an involuntary and rhythmic oscillation of the eyes that is typically indicative of an underlying neurological or vestibular disorder. It is characterized by repetitive and rapid eye movements, which can occur horizontally, vertically, or in a rotary pattern.

Senses and Usages

Sense 1: Medical Condition

In the medical field, pathological nystagmus is a condition that can result from various factors such as congenital abnormalities, brain injuries, certain medications, or diseases affecting the inner ear or central nervous system. It is often considered a diagnostic sign of an underlying issue and requires further evaluation by a healthcare professional.

Example Sentence:

Due to a head injury, the patient developed pathological nystagmus, which prompted the doctors to perform a comprehensive neurological examination.

Sense 2: Popular Misconception

Outside the medical realm, pathological nystagmus is sometimes mistakenly associated with abnormal eye movements resulting from excessive alcohol consumption. However, this is a misperception as alcohol-induced nystagmus is actually a temporary occurrence rather than a pathological condition.

Example Sentence:

Contrary to popular belief, the occurrence of nystagmus during a sobriety test does not necessarily indicate pathological nystagmus unless coupled with other relevant symptoms.

Sense 3: Local Usage

In local slang, pathological nystagmus may humorously be used to describe exaggerated or excessive rolling of the eyes in response to a particular situation or person.

Example Sentence:

Whenever her father tells a cheesy joke, she responds with a theatrical display of pathological nystagmus.
