Recurrent corneal erosions describe a disruption of the outermost surface of the cornea, which recurs in the same area of the cornea on a repeated basis. Although this clear tissue is typically very tough and resilient to damage, there are corneal dystrophies or degenerative diseases that may challenge the cornea’s integrity and ability to heal completely. If this disease or condition is chronic in nature, it can cause the cornea to suffer from recurrent erosion, a periodic loss of the outermost layer of the corneal tissue.
This loss of tissue generally results from a separation of this outer layer from the deeper layers of corneal tissue. When these corneal erosions occur, they leave nerve endings exposed, which can be very painful as well as cause a significant loss of vision. The recurrent nature of this condition relates to early (partial), yet structurally incomplete, healing of new outer layer of cells to the deeper layers. Corneal erosions may occur after traumatic injury to the cornea or they may form secondarily as a result of corneal disease.
The diagnosis of recurrent corneal erosion is aided by the patient supplying as much history as possible. Patients are also urged to track the frequency of erosion episodes and report any previous treatments. These measures will aid in better treating this chronic condition. Treatment may range from initial patching and use of medicated drops or ointments to office-based surgical procedures to aid tissue attachment and stability.
Pain and visual disturbances may occur needlessly if early warning signs are ignored. The sooner treatment can be started the better the chance we have of limiting the potentially damaging effects of this condition.
