Prenatal ultrasound diagnosis of complete cryptophthalmos, congenital aphakia, and corneal vascularization in a fetus: A case report and literature review

•Prenatal ultrasound diagnosis of complete cryptophthalmos, aphakia, and corneal vascularization.•Fetal ocular malformations are often associated with malformations of other organs.•This case provides a new basis for prenatal diagnosis of this rare eye disease. Complete cryptophthalmos, congenital aphakia, and corneal vascularization are relatively uncommon congenital eye malformations during the fetal period. Herein, we report a case of a fetus with complete cryptophthalmos, congenital aphakia, and corneal vascularization in both eyes and review previous prenatal reports of related cases. The patient was a 27-year-old pregnant woman, gravida 2, para 1, who was referred to our hospital for consultation at 23 weeks of gestation due to a diagnosis of fetal right renal agenesis at an external hospital. The ultrasound system of our hospital diagnosed the fetus with complete cryptophthalmos, congenital aphakia, and corneal vascularization, which was verified under the postnatal water basin test, anatomical and pathological sections. Fetal ocular malformations are often associated with malformations of other organs, and if ultrasound findings are associated with such malformations, attention should be paid to the ocular examination to avoid missing the diagnosis.
