The authors report a case of a bilateral limbal dermoid in a 4-year-old girl with no extraocular anomalies or systemic associations. The child's best corrected visual acuity was 20/50 in the right eye and 20/40 in the left eye. There was a small limbal dermoid located on the inferotemporal side in the right eye and a large elevated limbal lesion that extended over the visual axis in the left eye. Limbal dermoid excision and lamellar keratoplasty were performed in the left eye and followed by a simple excision of the limbal dermoid in the right eye. Histopathological examination confirmed the clinical diagnosis of a dermoid. At the 2-year follow-up visit, the child's best corrected visual acuity had improved to 20/30 in both eyes. Tumors of the corneal limbus are extremely rare. Simple excision is a viable method of treatment for smaller, superficial lesions, although larger lesions can obstruct the visual axis and produce irregular astigmatism and amblyopia. In this patient, surgical intervention resulted in a reasonable cosmetic and final visual outcome. [J Pediatr Ophthalmol Strabismus. 2021;58(4):e27-e29.].

双侧缘皮样作为儿童的孤立发现。

作者报告了一例 4 岁女孩双侧角膜缘皮样病变，无眼外异常或全身相关性。孩子的最佳矫正视力是右眼20/50，左眼20/40。右眼颞下侧有一个小的角膜缘皮样瘤，左眼有一个大的隆起的角膜缘病灶延伸至视轴。在左眼进行角膜缘皮样切除和板层角膜移植术，然后在右眼进行角膜缘皮样简单切除。组织病理学检查证实了皮样的临床诊断。在2年的随访中，孩子的双眼最佳矫正视力提高到20/30。角膜缘肿瘤极为罕见。简单切除是一种可行的治疗方法，适用于较小的、浅表病变，虽然较大的病变会阻塞视轴并产生不规则散光和弱视。在该患者中，手术干预产生了合理的美容效果和最终视觉效果。[J Pediatr Ophthalmol 斜视。2021;58(4):e27-e29.]。
