Hypopyon and pseudoendophthalmitis 1 month after vitrectomy for retinal detachment with subretinal hemorrhage

The presence of postoperative hypopyon warrants consideration of the diagnosis of infectious endophthalmitis, but other etiologies may mimic a hypopyon. The differential diagnosis of a postoperative hypopyon must include causes of pseudoendophthalmitis to avoid unnecessary and invasive interventions. The context and clinical presentation are the most important factors allowing such a distinction. A patient with a hypopyon and elevated intraocular pressure presented 1 month after pars plana vitrectomy for a hemorrhagic retinal detachment. Slit lamp examination disclosed khaki-colored cells layered in the anterior chamber, and a diagnosis of pseudoendophthalmitis was made. The hypopyon resolved without intervention.
