Corneal edema
Corneal swelling due to endothelial dysfunction or trauma, affecting visual clarity and surgical outcomes.
Full Definition
Corneal edema represents swelling of corneal tissue due to disruption of the normal deturgescence mechanisms, most commonly from endothelial dysfunction. This condition can be acute (following surgery or trauma) or chronic (from endothelial dystrophies like Fuchs'). The edema affects visual acuity and may complicate surgical visualization during procedures. Grading ranges from mild epithelial edema to severe bullous keratopathy with epithelial bullae formation. Treatment options include hypertonic saline drops, bandage contact lenses, or definitive corneal transplantation. Surgical documentation must record the severity, distribution, and underlying etiology of corneal edema.
Usage
Usage note: Grade the severity of corneal edema and identify underlying causes in documentation.
