【Causes・Disease】

Floaters are a state in which patients can see something like a black bug moving while looking at something. Black bug-like things come in different shapes and sizes, and sometimes they may drift about when patients move their eyes.
Symptoms appear at different ages. Some patients become aware of symptoms in their 20s. The causes of floaters are divided into physiological and eye diseases.
Floaters, which occur due to physiological causes, are closely related to the structure of the eye.
The eye is filled with a transparent jelly-like substance called vitreous, the composition of vitreous changes over time, and some of it can be wrinkled. This part will get cloudy and can cast ting shadows on your retina. The shadows patients see are called floaters.

In addition, when the vitreous atrophies with age, the back of vitreous may be detached from the retina, and the detached part looks like a black spot.
Typical eye diseases that cause floaters include retinal tear and retinal detachment.

They won’t disappear even if patients blink their eyes or rub their eyes, but the floaters don’t bother in the dark place.

【Treatment】
