Map-dot dystrophy of the cornea is relatively common and often has a genetic component. It consists of small spots or lines in the superficial cornea, and if these are in the line of sight, these deposits can interfere with vision. If there is a superficial injury, like a paper cut, the cornea can develop a condition known as a recurrent erosion syndrome (RES). RES is very painful and consists of recurring loss of the surface cells or skin covering of the eye. Otherwise, though, most cases of basement membrane dystrophy are not symptomatic, and the patient may be unaware of the dystrophy. If the spots or lines are in the line of sight or the cause of RES, there are several treatments available. No single treatment is effective for all cases. Treatment may consist of certain lubricating tear ointments, patching the eye, or therapeutic contact lenses. Surgical treatments include removing the surface cells to allow for regrowth, a light surface treatment with a fine needle, or laser treatment designed to get the cells to adhere more tightly. Often medical and surgical therapies are used together. If you have map-dot fingerprint dystrophy and are symptomatic from it, you should consult your eye doctor for appropriate treatment.
