Mrs MS, 81 years of age, presented to the emergency department with a 2 day history of left eye redness, worsening pain and watering. She had a history of glaucoma surgery with intra-operative topical antimetabolite in her left eye 3 years earlier. Visual acuity was documented as 6/18 in each eye. She was diagnosed with viral conjunctivitis and discharged home without ophthalmic review. Mrs MS re-presented the following day with worsening pain and vision. On examination, her left visual acuity was hand movements only. There was a 1.9 mm hypopyon (pus in the anterior chamber) and severe conjunctival injection (Figure 1). There was infection of her glaucoma surgery bleb at the superior limbus (Figure 2). Vitreous fluid obtained for Gram stain showed Gram positive cocci and Gram negative bacilli. She was treated with immediate intravitreal injection of ceftazidime 2.25 mg/0.1 mL and vancomycin 1.0 mg/0.1 mL. A vitrectomy was performed due to the severity of infection. One month postinfection her vision had recovered to 6/36.
