Trabéculaire

Trabéculaire refers to a filamentous structure found in the cornea of the eye, specifically in the trabecular meshwork. This meshwork consists of a grid-like network of trabeculae, or small beams or struts, which are responsible for draining the aqueous humor, a clear fluid that nourishes the cornea.

The trabecular meshwork is a critical component in the maintenance of intraocular pressure, as it allows the aqueous humor to flow from the anterior chamber of the eye into the bloodstream. Any disruptions to this meshwork can lead to increased intraocular pressure, potentially causing conditions such as glaucoma.

Research suggests that the trabecular meshwork is composed of collagen fibrils, elastic fibers, and macrophages, which work together to maintain the structural integrity of the meshwork and regulate the outflow of aqueous humor. The trabecular meshwork is also capable of adapting to changes in intraocular pressure, a process that is facilitated by the growth and deformation of the trabecular beams.

In certain ocular diseases, such as glaucoma and uveal melanoma, changes to the trabecular meshwork can lead to compromised aqueous outflow and increased intraocular pressure. Recent studies have focused on investigating the mechanisms underlying trabecular meshwork function and developing novel treatments for conditions associated with trabecular dysfunction.

Overall, the trabecular meshwork plays a vital role in maintaining the health and function of the eye, and understanding its workings is essential for delaying or preventing vision loss associated with ocular disease. Despite remaining a complex and enigmatic structure, research has shed light on the intricate mechanisms governing the trabecular meshwork and its function in the eye.
