H18.51
Endothelial corneal dystrophy
Clinical Classification Guidelines
Inclusion Terms
- Fuchs' dystrophy
Medical Intelligence & Overview
Endothelial corneal dystrophy, also known as Fuchs' dystrophy, is a progressive eye condition that affects the innermost layer of the cornea called the endothelium. This layer is vital for maintaining corneal clarity by regulating fluid and keeping the cornea transparent. When diseased, the endothelium loses its ability to function properly, leading to vision problems and, in severe cases, loss of eye transparency. This condition typically develops gradually, often affecting older adults, and can significantly impact their quality of life if not managed appropriately.
Causes & Symptoms
Clinical Causes: Age-related degenerative changes in the corneal endothelium Genetic predisposition, with some cases running in families Corneal endothelial cell loss due to injury or previous eye surgeries Certain medical conditions that impair corneal health
Key Symptoms: Blurred or cloudy vision that worsens over time Sensitivity to light (photophobia) Glares or halos around lights, especially at night Eye discomfort or a feeling of heaviness in the eye Possible eye swelling or edema in advanced stages
Diagnostic & Treatment
Diagnosis Path: Diagnosis involves a comprehensive eye examination which may include specialized imaging techniques such as slit-lamp biomicroscopy, which helps in visualizing corneal endothelial cell health and detecting characteristic guttae (deposits). Corneal pachymetry may also be used to measure corneal thickness, as swelling is a common feature. Early detection allows for better management of the condition and helps monitor its progression.
Treatment Protocols: Use of hypertonic saline eye drops or ointments to reduce corneal swelling Specialized contact lenses to improve visual acuity Surgical intervention such as endothelial keratoplasty (DSEK or DMEK) in advanced stages, which involves transplanting healthy endothelial cells Corneal transplantation procedures for severe cases where vision is significantly impaired
