Abstract: Objective To analyze the clinical effect of parents’ cunjunvtiva transplantation for treating wide range conjunctival tumor in children. Design Retrospective case series. Participants 12 children with wide range conjunctival tumor in Tongren Eye Center from Jan. 2012 to Dec. 2014, aged from 4 to 10 years old. In which, 2 cases were diagnosed of the primary conjunctival melanosis and 10 cases were diagnosed of conjunctival papilloma. All the tumors invaded at least more than 270 degrees range of bulbar conjunctiva, some involving the fornical conjunctiva and the palpebral conjunctiva. Methods The tumors were completely resected and patched with parental conjuntiva. All patients were followed up for 2.5±0.3 years. Main Outcome Measures Histopathological examination and slit-lamp examination. Results No recurrence and eyelid ball adhesion occurred in all the patients with pigmented tumors. Scattered recurrence occurred in 3 patients with papillary tumors after six months, but cured after resection. Two patients with papillary tumor had mild symblepharon after surgery but the movement of the eyeball was not affected. All patients were satisfied with the appearance. Conclusion For children with large range of conjunctival tumors, resection combined with parents’ conjunctival transplantation could reconstruct ocular surface and restore normal ocular function and appearance effectively
