Ultrasonographic findings of the optic disc in congenital glaucoma.

A 2-month-old female infant with intractable congenital glaucoma and diffuse corneal opacification underwent trabeculectomy with 5-fluorouracil (5-FU) injection in both eyes followed by penetrating keratoplasty (PKP) combined with partial cyclocryotherapy in the right eye. The latter procedure was undertaken despite the B-scan ultrasonographic finding of extensive optic disc cupping in order to provide the infant with some degree of improved visual function. The anatomic and functional results are discussed.
