The difference between a scratch (corneal abrasion
) and a defect, is that the corneal abrasion is a one time occurence with no future sequelae. A defect, refers to a problem with the outer layer of the cornea (epithelium
) that causes this layer to not properly anchor itself to the cornea once a corneal abrasion has occured. The problem with such a condition is that, often, upon awakening the eyes will be dry and the epithelium will adhere to the inside of the upper lid. As the eye first opens, the epithelium will come off causing pain, light sensitivity
, redness and swelling of the lid.
The key to resolving this issue is proper lubrication for a minimum of 6 weeks. Artificial tears and antibiotic drops during the day and ointment at night to avoid the dryness
that exhacerbates the condition. If this is not effective more invasive procedures can be undertaken.
The medical term for this condition is: Recurrent Corneal Erosion
In my opinion, a visit to a cornea specialist for close monitoring and proper treatment is the correct advice.
I hope this is helpful and that you feel better soon...
