Syneresis in the eye refers to the age-related breakdown of the vitreous humor, the gel-like substance that fills the space between the lens and the retina.
Understanding Vitreous Syneresis
As we age, the vitreous humor undergoes a process called syneresis. This process involves the following:
-
Breakdown of the meshwork: The vitreous humor is composed of a collagen meshwork filled with fluid. With age, this meshwork begins to break down.
-
Fluid pooling: As the meshwork degrades, areas of fluid form within the vitreous. This creates pockets of liquid.
-
Debris formation: The solid components of the vitreous gel collapse and condense, forming debris.
-
Floaters: This debris casts shadows on the retina, which are perceived as floaters. Floaters appear as small specks, strands, or cobwebs that drift across your field of vision.
In essence, syneresis leads to the vitreous becoming more liquid and less gel-like, with solid remnants floating within it. This is a normal aging process and is the primary cause of floaters. While usually harmless, a sudden increase in floaters can sometimes indicate a more serious condition, such as a retinal tear or detachment, and should be evaluated by an eye doctor.
