Abstract
Purpose: The aim of the paper is to present the case of a 53-year-old female patient who, based on the clinical picture and optical coherent tomography of the anterior segment (AS-OCT), was diagnosed with peripheral hypertrophic subepithelial degeneration (PHSD) and underwent surgical treatment in the form of superficial keratectomy with mechanical removal of degenerative plaques.
Methods: Analysis of AS-OCT images and corneal tomography based on Scheimpflug images and surgical treatment – superficial keratectomy with mechanical removal of degenerative plaques.
Results: Before treatment, the best corrected visual acuity (BCVA) for distance, as assessed by the Snellen chart, was 3/50 c.cor +10.50/-6.50 ax 18° in the right eye (RE) and in the left eye (LE) 5/10 c.cor +10.75/-3.00 ax 48°. Preoperative keratometry performed with the Pentacam device was K1 32.7 D and K2 46.0 D in the OP and K1 42.5 D and K2 44.7 D in the LE. Postoperative BCVA in RE was 5/8 c.cor +3.50/-1.00 ax 120° at 5 months of follow-up and in LE 5/6 c.cor +4.75/-1.00 ax 64° at 3rd month of observation. Postoperative keratometry (Pentacam) in RE K1 was 44.6 D, K2 46.9 D in the 5th month of observation, and in LE K1 45.6 D, K2 46.5 D in the 3rd month of observation. As a result of the treatment, BCVA improved, astigmatism decreased and corneal translucency improved.
Conclusions: AS-OCT and Scheimpflug-based corneal tomography are helpful in the diagnosis of PHSD. Superficial keratectomy with mechanical removal of degenerative plaques seems to be an effective treatment for PHSD
