Limbal choristomas – analysis of surgical technique and postoperative results (3 case reports)

Purpose To present three case reports of the limbal choristomas.Analyse surgical technique, pathology slides, evaluate postoperative results by anterior optical coherence tomography (OCT) and keratotopography. Methods Three patients with limbal choristomas were operated in Vilnius University Hospital. Location of the tumor was typical – inferiotemporal part of the limbus. All patients were admitted to the hospital lately after the time of diagnosis establishment. Patients were operated at the age of nineteen, six and fifteen years old. Case 1. Surgery was performed on the right eye of the nineteen years old lady. Visual acuity (VA) before the surgery 0,2 Case 2. Surgery was performed on the left eye of the six years old girl. VA before the surgery 0,8. Case 3. Surgery was performed on the right eye of the fifteen years old boy. VA before the surgery 0,2. Surgical technique‐excision of the limbal tumor and lamellar corneal graft transplantation. Results In case 1 and case 3 visual acuity of the operated eyes remaned the same as it was before the surgery. In case 2 postoperative visual acuity improved by 2 lines. Excised tumors were evaluated by pathologist and diagnosis of the limbal dermoid was established. Postoperative results were evaluated by anterior (OCT)and keratotopography. Conclusion 1.In purpose to prevent amblyopia scheduling of the surgery should be decided depending on the general health of the child and size of the tumor. 2.Appropriate surgical technique should be chosen after the evaluation of the size and location of the limbal dermoid. 3.Modern diagnostic tools such as OCT and keratotopography are important for the evaluation of postoperative results.
