Achondroplasia is an autosomal dominant congenital disorder of enchondral ossification. It is clinically characterized by low stature, craniofacial deformity, and vertebral malformation. Associated ophthalmic features include telecanthus, exotropia, angle anomalies, and cone-rod dystrophy. A 24-year-old male presented with decreased vision bilaterally and typical achondroplasia. The best corrected visual acuity was 20/70 in both eyes. Anterior segment examination was normal. Fundus examination revealed a well-demarcated circular paramacular lesion in both eyes. As macular coloboma and achondroplasia are developmental disorders, the funduscopic examination is required in patients with achondroplasia.
软骨发育不全是一种常染色体显性遗传性软骨内成骨的先天性疾病。其临床特征为身材矮小、颅面畸形和椎体畸形。相关的眼科特征包括内眦距增宽、外斜视、角膜缘异常和视锥视杆营养不良。一名24岁男性因双眼视力下降就诊,伴有典型的软骨发育不全。双眼最佳矫正视力均为20/70。眼前节检查正常。眼底检查发现双眼有边界清晰的圆形黄斑旁病变。由于黄斑缺损和软骨发育不全均为发育性疾病,因此软骨发育不全患者需要进行眼底检查。
