Summary
This video describes and demonstrates the Six Cardinal Fields of Gaze test, used to evaluate cranial nerves 3, 4, and 6, which control eye movement. It shows both the "star pattern" and "H pattern" methods for performing the test.
Highlights
Introduction to the Six Cardinal Fields of Gaze
00:00:02
The video introduces the Six Cardinal Fields of Gaze test, explaining that it evaluates cranial nerves 3, 4, and 6, which are responsible for eye movement.
Demonstrating the Star Pattern
00:00:10
The demonstrator instructs the patient to follow a red-tipped object with only their eyes, keeping their head still. The object is moved to the extremes of the patient's gaze to perform the "star pattern" of the test.
Normal Variant: Nystagmus
00:00:38
On lateral gaze, the video notes that slight nystagmus (involuntary eye movement) can be a normal variant.
Demonstrating the H Pattern
00:00:49
The video then demonstrates the "H pattern" for the same test, stating that either the star or H pattern is acceptable to perform.
Identifying Cranial Nerve Deficits
00:01:06
Both patterns of the test help in discerning if there is a deficit in any of the involved cranial nerves (III, IV, or VI).
