Corneal Edema - EyeWiki
Corneal edema is defined as the increase in the thickness of cornea due to the accumulation of extracellular fluid in epithelium and stroma resulting in loss of corneal transparency. Conditions that cause corneal edema can be categorized into 5 groups, according to etiological factors:
Corneal Edema: Causes, Symptoms & Treatment - Cleveland Clinic
2023年8月18日 · Corneal swelling, or edema, happens when your eyes aren’t able to pump out enough fluid, causing fluid to back up. You may have blurred vision or eye discomfort. Your provider may suggest medications or surgery.
Corneal Stromal Abnormalities: Haze, Ectasia, Keratitis and More
2023年2月15日 · Signs typically include stromal edema, new keratic precipitates on the endothelium, anterior corneal infiltrates and anterior chamber inflammation. Subepithelial infiltrates, epithelial line, conjunctival hyperemia or neovascularization may also be present.
What is the treatment for corneal edema? - American Academy of ...
2024年2月21日 · Treatment of corneal edema—or swelling of the cornea—is based on what's causing the swelling. Most commonly, the endothelial cells responsible for pumping fluid out of the cornea are damaged. In glaucoma, the intraocular pressure needs to be reduced. If the swelling is due to an inflammatory condition, the inflammation needs to be treated.

Increased stromal fluid (edema) increases corneal hydration and disrupts the lamellar arrays, thus resulting in loss of transparency (often described clinically as corneal "haze" or "opacity").
Corneal Edema - Ento Key
2016年7月11日 · The corneal stroma plays a primary role in maintenance of corneal shape and physical strength. Its constituents, in conjunction with the endothelium, help preserve transparency. Stromal edema may be caused by malfunction of the endothelium and/or epithelium. When the stroma swells, the diameter of the collagen fibrils remains constant.
A Closer Look at Corneal Inflammation
2012年11月15日 · Swelling of the corneal stroma manifests as an increase in stromal thickness. The appearance of edema in this region varies from a mild granular haze to a dense gray opacity and may produce folds in Descemet’s membrane if severe.
