PURPOSE: To describe the natural history, management, and visual outcome in children with congenital primary aphakia (CPA).
METHODS: This is a multicenter retrospective consecutive case series from five academic centers in England and North America.
RESULTS: A total of 27 eyes of 14 patients were included (male:female, 1.7:1). Thirteen patients had bilateral CPA, and 1 patient had unilateral CPA. Mean age at diagnosis was 18 months (median, 21; range, 0.5-144). Of 11 patients who underwent genetic testing, 9 had FOXE3 pathogenic variants. In all patients, visual acuity at presentation was not better than fixing and following light. Typical findings included silvery appearance of the cornea with vascularization (96%), glaucoma (81%), iridocorneal adhesions (74%), optic nerve coloboma (55%), abnormal vitreous (33%), retinal detachment (30%), and aniridia with hypoplasia of ciliary body (19%). Surgical interventions in select patients included penetrating keratoplasty (PKP), glaucoma drainage device implantation, and cyclophotocoagulation (CPC).
CONCLUSIONS: Eyes with corneal ectasia and a silvery appearance of the cornea with vascularization should alert the physician to the possibility of CPA. Glaucoma causes globe enlargement and may increase the risk of corneal perforation, but glaucoma is often refractory to medical treatment, and the threshold for surgical treatment should be low. PKP outcomes are very poor.
