Overview

Infection inside the eye, most often after cataract surgery, an intravitreal injection or penetrating trauma, presenting with falling vision and a marked anterior chamber reaction. Pain and hypopyon are common but neither is required, and their absence after an injection does not lower the concern. Any postoperative eye that deteriorates rather than improves is referred as an emergency, because sight is lost within hours.

Recognition

Symptoms: what patients report

  • Recent intraocular surgery, intravitreal injection, or penetrating ocular procedure followed by worsening symptoms.
  • Marked pain and photophobia — common, but pain can be absent, especially after intravitreal injection or in atypical presentations.
  • Significant reduction in vision.
  • Marked redness or deep aching postoperative eye.

Signs: what the examination shows

  • Severe anterior chamber reaction.
  • Hypopyon may be present.
  • Marked conjunctival or ciliary injection.
  • Vision is often significantly reduced compared with expected recovery.
