Purpose of the Study:

To present the first documented case of an ocular gossypiboma (retained foreign body) of a mitomycin-C-soaked sponge confirmed echographically using diagnostic ultrasound B-scan after Ahmed valve surgery.

Patients and Methods:

A patient who underwent phacoemulsification with Ahmed valve implantation surgery had a retained Weck-Cels sponge soaked with mitomycin-C. With the use of ocular ultrasound B-scan, the retained sponge was localized and a second procedure was performed to explant it.


In cases of ocular gossypiboma the use of ultrasound modalities can be a valuable tool especially because B-scan access is common and can be cost-effective.
