What is Corneal Swelling?
Corneal swelling (also called corneal edema) is an inflammation of the outermost layer of the eye. The cornea is a clear layer of tissue that looks like a smooth, dome-shaped piece of glass. By blocking irritating debris and controlling the way light enters the eye, your cornea helps to protect your eyes and focus your vision.
The cornea has a layer of cells along its inner surface called the endothelium. The endothelium pumps liquid out of the cornea, keeping your cornea healthy and vision clear. When the endothelium is damaged, fluid can build up in the cornea and the cornea may swell. This swelling can cause vision impairment.
The ophthalmology team at MedStar Georgetown University Hospital provide cutting-edge care for corneal swelling. Our clinicians will work to assess your corneal condition, determine underlying cause, and create a customized treatment plan. Your eyesight deserves expert care.
What Causes Corneal Swelling?
One common cause of corneal swelling is Fuch’s endothelial dystrophy, a heredity condition that causes a gradual loss of endothelial cells and often becomes noticeable when patients are in their 50’s. Corneal swelling can also be caused by the inflammatory effects of medical conditions like herpes simplex, eye surgery, medications, and irritation related to use of contact lenses.
What are the Symptoms of Corneal Swelling?
Many patients seek treatment for corneal swelling after noticing that their vision is becoming blurred. Other common symptoms of corneal swelling include:
• Glare or haloes around lights
• Sensitivity to light and/or touch
• Scratching sensation in the eye
• In severe or advanced cases, blisters may form on the surface of the eye
How is Corneal Swelling Diagnosed?
Diagnostic tests for corneal scars are completed in an outpatient setting. Your MedStar Georgetown ophthalmologist will talk with you about your medical history and symptoms. Then, he or she will conduct an eye exam. During the exam, your ophthalmologist will look for clouding of your cornea. He or she may use magnifying tools, such as a slit lamp or ophthalmoscope, to get a better view of your eye. Your doctor may also perform an ultrasound or measure the thickness of your cornea using a process called optical pachymetry.
How is Corneal Swelling Treated?
In formulating your treatment plan, your MedStar Georgetown ophthalmologist will consider the severity and underlying cause of your corneal swelling. Treatment options may include:
• Hypertonic solutions (for example, Muro128) used to reduce swelling
• Medications such as antibiotics, corticosteroids, and beta-adrenergic blockers
• Bandage contact lenses (thin, breathable lenses that are high in water content) can be used to soothe blisters on the eye
• In some cases, treatment of the underlying medical condition causing the edema will also resolve the corneal swelling
