What is Microcystic corneal edema?
Epithelial edema clinically causes a hazy microcystic appearance to occur in the epithelium in mild-to-moderate cases of corneal edema (Figure 9.1A), significantly decreasing vision, and increasing glare.
What is pseudophakic corneal edema?
Pseudophakic corneal edema (PCE) refers to irreversible corneal edema and endothelial cell damage that occurs after cataract extraction and intraocular lens (IOL) implantation (Fig. 1). When the patient does not have an IOL implant, the condition is referred to as aphakic corneal edema (ACE).
How is corneal edema treated?
Corneal Edema Treatment Options If there is swelling, your ophthalmologist may recommend saline eye drops. If swelling becomes severe enough to cause significant vision issues, surgery may be required to either replace the cornea with a corneal transplant, or DSEK surgery, which replaces just the endothelial layer.
What medications can cause corneal edema?
The use of certain drugs can also increase your risk for corneal edema:
- benzalkonium chloride, a preservative used in many eye drops and anesthetic drugs.
- chlorhexidine (Betasept, Hibiclens), an antiseptic used to disinfect the skin before surgery.
- amantadine (Gocovri), a drug used to treat viruses and Parkinson’s disease.
What causes Microcystic edema?
Conclusions: Microcystic macular edema is not specific for demyelinating disease. It is a sign of optic neuropathy irrespective of its etiology. The distinctive intraretinal anatomy suggests that MME is caused by retrograde degeneration of the inner retinal layers, resulting in impaired fluid resorption in the macula.
Can corneal edema be cured?
The only currently available cure for corneal edema is to have a corneal transplant. HOW IS CORNEAL EDEMA TREATED? Out of the possible treatment options available for corneal edema, the treatment chosen will depend on the cause and the severity of the condition.
What is Irvine Gass syndrome?
Irvine-Gass syndrome, first described by Irvine in 1953,1 is a condition in which cystoid macular edema (CME) develops in a patient after cataract surgery. Irvine-Gass syndrome is recognized as one of the most common causes of poor visual outcome following cataract surgery.
What causes pseudophakic bullous keratopathy?
The main cause of bullous keratopathy is the loss of endothelial cells due to surgical trauma, especially in cataract surgery at sixth decade patients, with or without lens implantation [6,7].
Is corneal edema curable?
How long can corneal edema last?
Cornea swelling or corneal edema may cause some short-term blurriness. Normally, swelling will subside within a few days and vision becomes clear.
Can glaucoma cause corneal edema?
In about 25% of cases, iridocorneal adhesions develop, and the corneal changes often progress to edema. Endothelialization of the chamber angle is uncommon but can result in ectropion uvea and glaucoma.
Is corneal edema serious?
Edema may result in loss of transparency, and this may lead to eye redness, pain, possibly irreversible scarring of the cornea, and even blindness.
