Molteno rip-cord suture hypopyon.

Seven of 27 eyes developed hypopyons following removal of a 4-0 chromic suture that had been placed intraoperatively in the lumen of the tube of a Molteno implant as a temporary occlusion device. The hypopyons were sterile to anterior chamber tap and in six of seven cases resolved with only routine antibiotic coverage. Surgeons contemplating using an internal chromic suture occlusion in Molteno implants, however, should be aware of this potential problem and adopt a conservative, noninvasive approach.
