What is corneal detachment?

Corneal epithelial detachment refers to the shedding or loss of the corneal epithelial layer or part of its structure. The cornea is a transparent tissue located at the front of the eye and consists of multiple layers, including the epithelial layer, Bowman's layer, stromal layer, Descemet's membrane, and endothelial layer. The term "corneal detachment" usually refers to damage or loss of the corneal epithelial layer, which may be caused by factors such as corneal inflammation, trauma, dry eye, incomplete eyelid closure, medication side effects, impaired neurotrophic supply, environmental influences, or prolonged contact lens wear. Common symptoms include foreign body sensation, photophobia, decreased vision, ocular congestion, and increased secretions. Timely treatment is essential and may involve procedures such as ocular surface reconstruction or corneal transplantation.
