Subluxated cataractous lens and high myopia: An uncommon association in an achondroplasia child

Abstract

Achondroplasia is an autosomal dominant congenital disorder of endochondral ossification, induced by abnormal activity of fibroblast growth factor receptor 3. Affected individuals have short stature and often present with neurological and skeletal complications. Most have normal intelligence. Ocular association with achondroplasia include simple microphthalmos, congenital-onset glaucoma with presumed Axenfeld–Rieger anomaly, telecanthus, exotropia, inferior oblique overaction, angle anomalies, Duane retraction syndrome, cone-rod dystrophy, fundus albipunctatus, chorioretinal coloboma, macular coloboma, keratoconus, and developmental cataract. A 6-year-old achondroplasia boy with developmental delay had a high axial length (high myopia) in both eyes. This child had a left eye subluxated cataractous lens, while the other eye showed mild lens changes. All achondroplasia patients should be routinely screened in detail for lens and other ophthalmological anomalies so that they can undergo timely intervention and management.
