floating eye phenomenon
Introduction
Introduction Eyeball floating phenomenon: the colorless and transparent gel-like body in the 4/5 cavity after filling the eyeball, mainly composed of collagen fiber filament and 98.5%-99.7% water. The vitreous itself has no blood vessels and its metabolism is very low. Its nutrition comes from the choroid and aqueous humor. The vitreous is susceptible to various physical, chemical, traumatic, inflammatory, degenerative, decomposing, and liquefaction phenomena. It is characterized by a variety of floating objects such as a bit shape, a line shape, and a spider web shape, and floats up and down with the movement of the eyeball.

First, the general inspection:
Directly observe the situation when the patient is looking straight ahead or when the patient follows the examiner's finger in a certain direction. Some need to be covered by a single eye for inspection.
Second, special inspection:
Equipment inspection such as nystagmus current map.
Diagnosis
