Macular edema associated with intraocular ointment after cataract surgery

In this case, ofloxacin ointment had presumably migrated into the anterior chamber through a corneal incision after cataract surgery. The fact that the droplet of ointment was able to be detected more than one year after the cataract surgery suggests that dispersed tiny droplets can slowly coalesce into a globular droplet and wander between the anterior and posterior chambers, thereby causing uveitis, corneal endothelial cell damage, and macular edema. The removal of the intraocular ointment resolved these complications. This is the second report of intraocular ointment causing macular edema.
