Synchysis means
**Core Concept**
Synchysis refers to the separation or disruption of the layers of the lens or vitreous in the eye, often resulting in the leakage of fluid into the anterior chamber.
**Why the Correct Answer is Right**
The correct answer is related to the disruption of the vitreous or lens in the eye, which leads to the leakage of fluid into the anterior chamber. This condition can occur due to various factors, including trauma, inflammation, or degeneration of the vitreous or lens. The vitreous is a clear gel-like substance that fills the space between the lens and the retina, and any disruption to this gel can lead to synchysis.

**Option C:** This option is incorrect as it describes a different condition, which is the detachment of the retina. Synchysis is not related to retinal detachment.
**Clinical Pearl / High-Yield Fact**
Synchysis can be a sign of underlying conditions such as trauma, inflammation, or degeneration of the vitreous or lens. It is essential to identify the underlying cause of synchysis to provide appropriate treatment.
