An 8-year-old boy was presented for a routine ophthalmological examination. His right eye had a visual acuity of 20/25. Examination of the anterior segment revealed a clear cornea with Y-shaped crystalline opacities (anterior Y-suture lines of the right eye); examination of the posterior segment was unremarkable. Examination of the left eye did not reveal any abnormalities. The sutural cataract was diagnosed and considered to be minimally progressive; it did not require surgery because of its minimal visual impact. Eyeglasses were prescribed, and the visual acuity of the right eye was improved to 20/20.
