Comprehending its anatomy provides insights into how diseases affecting the cornea may lead to severe vision impairment or blindness. Moreover, the role of endothelial cells, which maintain corneal transparency and health, is integral in determining the necessity and timing for DMEK surgery.

Anatomy of the Cornea

The cornea is a transparent, dome-shaped structure at the front of the eye. It is approximately 0.5 millimeters thick and consists of five distinct layers:

Epithelium: The outermost layer, responsible for acting as a protective barrier against dust, debris, and microorganisms. It also plays a role in absorbing nutrients.
Bowman's Layer: A thin but strong layer that provides stability and protection to the cornea. Its injury can lead to scarring, affecting vision.
Stroma: The thickest layer, comprising collagen fibers and keratocytes. This layer gives the cornea its shape and contributes to its light-reflecting properties.
Descemet's Membrane: A thin, durable layer that serves as a basement membrane for the endothelium and plays a role in wound healing.
Endothelium: The innermost layer, consisting of a single layer of cells that regulate fluid and nutrient exchange between the cornea and the anterior chamber of the eye. Its functionality is vital for maintaining corneal transparency.

The structure of the cornea is designed for refracting light. Disturbances or diseases affecting any of these layers can result in loss of transparency, leading to vision problems. For instance, endothelial dysfunction is a common reason for corneal transplant surgeries.

Role of Endothelial Cells

Endothelial cells are critical for preserving corneal clarity and function. These cells maintain the proper balance of hydration within the stroma by pumping excess fluid out of the cornea. If endothelial cells are compromised—due to diseases like Fuchs' dystrophy, for example—the cornea can become edematous, leading to blurred vision and other complications.

Some key points regarding endothelial cells include:

They have limited regenerative capacity. Once damaged or lost, they do not regenerate effectively, making their health essential for corneal function.
The density of endothelial cells naturally declines with age. Usually, a cell count of less than 400 cells/mm² can result in visual impairment.
Their functionality can be assessed through specular microscopy, aiding in determining the need for DMEK surgery.

"In DMEK surgery, the focus is on restoring the endothelium's health, which can greatly improve visual outcomes for patients suffering from diseases affecting this layer."
