Suprachoroid lamina

Suprachoroid Lamina is a thin layer of tissue found in the eye. It is located between the choroid and the sclera, two other important structures in the eye. The suprachoroid lamina plays a crucial role in the eye's function and health.

Etymology

The term "Suprachoroid Lamina" is derived from the Latin words "supra," meaning above, and "choroid," referring to the choroid layer of the eye. "Lamina" is also a Latin word, meaning a thin layer or plate. Thus, "Suprachoroid Lamina" refers to the thin layer located above the choroid in the eye.

Anatomy

The Suprachoroid Lamina is a thin, fibrous layer that lies between the choroid and the sclera. It is part of the uvea, which also includes the iris and the ciliary body. The suprachoroid lamina is rich in melanocytes, which are cells that produce the pigment melanin. This layer also contains blood vessels that supply nutrients to the eye.

Function

The primary function of the Suprachoroid Lamina is to provide a pathway for blood vessels and nerves that supply the outer layers of the eye. It also plays a role in the regulation of intraocular pressure, which is crucial for maintaining the shape of the eye and for proper vision.

Clinical Significance

Abnormalities or damage to the Suprachoroid Lamina can lead to various eye conditions. For instance, inflammation of this layer, known as suprachoroiditis, can cause blurred vision and eye pain. Other conditions that may involve the suprachoroid lamina include glaucoma, macular degeneration, and retinal detachment.
