Endogenous endophthalmitis caused by Aeromonas hydrophila following intravenous blood transfusion.

The genus Aeromonas is a natural inhabitant of aquatic environments. These microorganisms are commonly regarded as pathogens of fish. Aeromonas' involvement in the eye is rare, with only a few reported cases of endogenous endophthalmitis. Here, we report a case of a woman in her early 20s presenting with sudden onset diminution of vision in her right eye, along with pain, redness and whitish opacity following a blood transfusion. Clinical examination suggested endogenous endophthalmitis. Despite negative blood, urine and stool cultures, evisceration and culture of intraocular contents revealed Aeromonas hydrophila Based on antibiotic sensitivity reports, she was started on broad-spectrum parenteral antibiotics. This case emphasises the importance of recognising the potential for nosocomial infections, including rare complications such as endogenous endophthalmitis, following blood transfusion.
