Vitreous opacity

The vitreous humor is a transparent, gel-like substance that makes up the majority of the eyeball. Vitreous opacity refers to the presence of opaque bodies within the vitreous humor, leading to blurred vision and the sensation of floaters, dark spots, or clouds moving in front of the eyes. This condition is often caused by vitreous liquefaction and posterior detachment due to aging, or by diseases such as vitreous inflammation or hemorrhage. It is not a standalone disease but rather a common manifestation of various eye conditions. It can be divided into two types: Physiological vitreous opacity: Commonly seen in middle-aged and elderly individuals experiencing degenerative changes in the vitreous humor, a significant portion of whom are myopic patients. Generally, it does not affect vision and usually does not require treatment; regular follow-up is sufficient, or some medication may be given. Pathological vitreous opacity: Often caused by eye trauma, vitreous hemorrhage, intraocular inflammation, retinal diseases, uveitis, and other conditions. If not treated promptly, it can severely impair vision.
