Ultrasonographic characteristics of congenital corneal staphyloma.

This case report describes the ultrasonographic characteristics of congenital corneal staphyloma (CCS) in a neonate on the birth day, with a massively staphylomatous and ectatic left cornea, which was forward protrusive between the eyelids. Ultrasound biomicroscopy (UBM) revealed the cornea of the left eye as thin and ectatic, with an irregular contour and unidentified layers. The anterior chamber was extraordinarily deep. Apart from histology, UBM can be used for understanding the microstructure of the anterior ocular segment, which may directly guide the diagnosis of CCS in a timely manner.
