When recurrent corneal erosions occur with macular corneal dystrophy, they are treated like any other form of recurrent corneal erosion. Under the care of an ophthalmologist, bandage contact lens along with antibiotics can be prescribed. Alternatively, patching with an antibiotic ointment or frequent application of an antibiotic ointment can be used.
Once the acute episode of recurrent corneal erosions has resolved, preventive treatment may include sodium chloride 5% drops (eg, Muro 128) or artificial tear lubricating drops during the day and sodium chloride 5% ointment (eg, Muro 128) or lubricating ointment at bedtime.
If recurrent corneal erosions occur despite medical therapy, then excimer laser phototherapeutic keratectomy (PTK) may be considered.
Sunglasses are often helpful for severe glare symptoms.
Excessive corneal erosions or a mild visual decrease can be treated with excimer laser PTK, which works best when the opacities are superficial. The excimer laser removes superficial corneal opacities, smooths the corneal surface, and allows the epithelium to re-adhere more tightly.
If visual acuity worsens and the opacities are deep, lamellar or full-thickness corneal transplantation can be performed. Although the success rate for corneal transplantation is high, macular corneal dystrophy deposits can recur with time.
The use of fibrin glue in lamellar therapeutic keratectomy for the treatment of anterior corneal opacities has been assessed as safe and effective for attachment. However, the technique needs to be refined for ease and safety.
