Descemet's membrane is a thin, clear layer of tissue that lies between the corneal stroma and the endothelium. It acts as a protective barrier, supporting the innermost cells of the cornea and helping the eye stay transparent and properly shaped. Despite being only a few micrometers thick, it maintains corneal strength and clarity.

Conditions like keratoconus, trauma from contact lenses, or elevated eye pressure can cause tiny tears known as Descemet's membrane breaks. These breaks allow fluid to enter the cornea, leading to swelling and blurred vision. Some people also develop genetic or age-related disorders that weaken this layer over time.
Eye doctors diagnose damage using slit-lamp exams and imaging tests such as optical coherence tomography (OCT). Treatment depends on the cause. Mild swelling may respond to saline eye drops that draw out excess fluid. Severe or recurring cases sometimes need surgical repair or corneal transplant, including modern procedures like Descemet's membrane endothelial keratoplasty (DMEK). Early detection improves the chance of recovery and helps protect long-term vision.
People with corneal disorders often notice cloudy or hazy vision, glare, or sensitivity to light. Regular monitoring helps track changes and guide treatment. Using prescribed eye drops, managing underlying health conditions, and following medical advice are vital to maintaining clear vision.
Minor injuries sometimes heal naturally, but larger tears may need medical treatment.
Blurred vision, light sensitivity, and corneal swelling are common signs.
Yes, procedures like DMEK can replace the damaged layer and restore clarity.
If your vision becomes suddenly cloudy or "steamy," particularly in the morning, consult a corneal specialist. This can indicate that the membrane is failing to pump fluid out of the cornea, a condition that needs management.
