Abstract

Purpose: Phototherapeutic keratectomy (PTK) with 193-nm excimer laser is a safe and effective procedure for the treatment of superficial corneal pathology. We aimed to review the use of PTK for the treatment of corneal macular dystrophy (MCD). Methods: Case report and literature review Results: A 16-year-old boy presented to an ophthalmologist with a 4-year history of reduced vision, glare and photophobia in his left eye. He was diagnosed with corneal macular dystrophy and underwent sequencing of the CHST6 gene. Left excimer PTK with mitomycin C was performed. He remained relapse free until 18 months post procedure when his visual acuity declined and the stroma appeared more “milky”. He underwent a penetrating keratoplasty in his left eye 24 month following the initial PTK. Conclusion: Phototherapeutic keratectomy is an effective means of visual restoration in patients with macular corneal dystrophy and may delay penetrating keratoplasty. Patients should be counselled regarding the high risk of recurrence. This is the first reported case of a CHST6 gene positive patient with MCD that was treated with phototherapeutic keratoplasty.
