Can your cornea come off

Think of gluing two pieces of wood together: if they are exceptionally smooth, they might not adhere as well as if the surfaces were rough. Those who have an abnormal structure to the corneal epithelium called map-dot-fingerprint dystrophy are at much greater risk of poor healing following a corneal abrasion and, thus, can develop recurrent corneal erosion.

Just as it is nearly impossible to see a corneal abrasion with the naked eye, the same is true for recurrent corneal erosion. What is most important is the time course. In recurrent corneal erosion, the patient can remember having had a corneal abrasion relatively recently usually within the past 3—10 days and then, most often when first opening the eye in the morning, feels a sudden burst of pain accompanied by symptoms of a corneal abrasion, which are: Lots of watery tearing Sensitivity to light especially bright light Blurry vision Redness of the eye Spasm of the muscles surrounding the eye resulting in squinting Feeling that something is in the eye Pain.

The self-care for recurrent corneal erosion is very similar to that for corneal abrasions, which is: Keep the eye shut. Never rub the involved eye at any time even if it feels fine. Immediately remove a contact lens.

Contact lens wearers should always have a back-up pair of glasses for when contact lenses shouldn't be worn. Use artificial tears to bathe the eye. Use clean water to rinse the eye. Use sunglasses to reduce the light sensitivity. What is very important in self-care is learning how to open your eyes when awakening. The friction of the lid against the sick cornea is enough to rip off a piece of the corneal epithelium, as noted above. So, if you suspect you have recurrent corneal erosion, keep the eye closed firmly and only open the good eye.

Since both eyes move together and the eye is most painful when it moves, it is often helpful to rest the other eye as well. Your ophthalmologist may recommend an antibiotic to prevent infection. Anesthetic drops can relieve pain and facilitate examination but may keep the eye from healing properly if used repeatedly.

Anesthetic drops should never be used as a treatment. Long after an abrasion has healed it may spontaneously recur, and is often noticeable upon awakening in the morning. Recurrent corneal erosions often require repeat patching or the use of ointments at bedtime. Sometimes a soft or bandage-type contact lens is used to facilitate healing.

Occasionally, treatment of the corneal surface with minor surgery is necessary to prevent recurrences. If bacteria get into the tissues under the protective corneal epithelium, infection or a corneal ulcer can result.

These complications can be very serious and cause loss of vision. Proper care by you and your ophthalmologist are necessary to help prevent serious consequences. Reviewed by Christopher T. This removes scar tissue and creates a clean and slightly roughened surface. Doxycycline is an antibiotic with anti-inflammatory properties.

It promotes epithelial healing and improves the function of the meibomian glands in the eyelid. These glands secrete oily substances that lubricate the cornea and prevent drying of the surface of the eye. Saline salty ointment may be more effective than other ointments.

It reduces corneal epithelial swelling during the night. Serum is the watery component of blood. It can be collected and made into eye drops.

Serum contains many substances that promote corneal epithelial healing. What is it? Introduction The cornea is the clear window at the front of the eye. Symptoms Corneal erosions that follow trauma may occur a few days or several months after the injury.

Prognosis RCES may resolve spontaneously but most cases require treatment. Treatment The treatment of RCES may involve: Pain relief Lubricants Eye movement training Bandage contact lenses Removal of epithelial cells Corneal micropuncture Laser resurfacing of the stroma Anti-inflammatory drops Doxycycline tablets Saline ointment Serum eye drops Pain relief Eye pads, ointments and gels, pupil dilation, bandage contact lenses and pain relieving tablets such as paracetamol and low dose amitriptyline can all be very useful.

Antibiotics Antibiotic ointments may be prescribed for a few days to reduce the risk of infection. Lubricants Gels and soft ointments form a soft lubricant barrier between the eyelid and cornea.

Eye movement training Many erosions can be avoided by patients learning to wake with their eyes closed and still.
