Dua's layer

Dua's layer is a thin, previously unrecognized, part of the cornea in the human eye. It was discovered in 2013 by Harminder Dua, a professor of ophthalmology at the University of Nottingham, and his team. The layer is located at the back of the cornea between the corneal stroma and Descemet's membrane.

Etymology

The layer is named after its discoverer, Harminder Dua. The term "Dua's layer" was first used in a paper published in the journal Ophthalmology in June 2013.

Structure

Dua's layer is only about 15 micrometres thick, but it is incredibly tough and strong. It is made up of thin plates of collagen and is impervious to air. The layer is located at the back of the cornea, just in front of Descemet's membrane.

Function

The function of Dua's layer is not yet fully understood. However, it is believed to play a vital role in the structure of the cornea and may contribute to the cornea's resistance to damage and disease. It may also play a role in corneal hydrops, a condition in which fluid accumulates in the cornea, causing it to suddenly become opaque and vision to be lost.

Clinical significance

The discovery of Dua's layer has significant implications for corneal surgery, including corneal transplant, keratoplasty, and refractive surgery. Understanding the presence and properties of this layer could lead to safer and more effective surgical procedures. It may also have implications for the treatment of corneal diseases and conditions.
