A 2-years old child patient who had interestingly persistent corneal epithelial erosion for 4 months was brought to our outpatient clinic. The patient had complained of single sided epiphora, erythema and swelling of her right upper eyelid. Her parents pointed out that they referred to a different eye specialist and also applied various topical drops but no clinical improvement has occured. Right central corneal epithelial injury was noted in biomicroscopic anterior segment examination. Due to patient age, failure of the previous treatment and foreign body suspicion; examination under inhalation anesthesia was proposed to parents. Under anesthesia, lacrimal lavage was performed and no obstruction was observed. When the right upper eyelid was everted, single 0.4x0.2 cm sized grey-white mass was seen. There was no conjunctiva on the top of the lesion. The mass was excised with forceps assistance. Histopathologically epithelial cell casts and degenerative products were observed. According to clinical and pathological findings, this conjunctival mass was diagnosed as conjunctival concretion.

This case emphasizes the importance of upper eyelid eversion in cases with persistent corneal eptihelial erosion in children. Although it is a rare condition, conjunctival concretion must be kept in mind especially in differential diagnosis of children with single-sided persistent corneal epithelial erosions.
