Abstract:
PURPOSE: To evaluate the result of excision and lamellar keratoscleroplasty using ultrasound biomicroscopy in limbal dermoid. METHODS: We retrospectively analyzed in 10 patients with limbal dermoid, who were performed preoperative ultrasound biomicroscopy to access the extent of the lesion and the depth of corneal involvement, and underwent excision and superficial keratoscleroplasty with a minimum follow-up period of 6 months RESULTS: On ultrasound biomicroscopic examination, the dermoid showed highly reflective, homogeneous echo density than surrouding tissue, leading to identifying the lateral margin of the lesion and depth of involvement. The mean maximun thickness of the lesion was 1.1 +/- 0.2mm. The six of 8 patients, who were feasible to test visual acuity, had no change in best corrected visual acuity, and 2 of 8 patients gained less than 1 line. Most patients (9 of 10), except one, had good or excellent cosmetic results with no haze (5 of 10) or minimal haze (4 of 10). CONCLUSIONS: In limbal dermoid, ultrasound biomicroscopy was helpful in accessing the extent of the lesion and the depth of involvement preoperatively, and excision and lamellar keratoscleroplasty leads to good results without complication.
