Sir,

We thank Hedayatfar and Chee1 for their interest in our article.2 In the below we hope we have answered the questions they raised.

1. We speculated the pink hypopyon was caused by severe necrosis because Klebsiella pneumonia causes classic cases of pneumonia, characterized by brick-red or ‘currant jelly’ sputum. The biological effects of Klebsiella pneumonia in animal study produced fever, capillary haemorrhage, hypotension, and circulatory collapse in animals, symptoms that are similar to those seen in humans with Gram-negative sepsis.3 We agree that red blood cells were not revealed on the aqueous smear. It might be caused by haemolysis before fixation.

2. This reported case is a healthy individual who does not have diabetes mellitus or other systemic diseases. The pink hypopyon in our case was most likely caused by Klebsiella pneumonia, based on the clinical course and the culture reports of vitreal aspirates and liver abscess. This patient had rapid visual loss in 2 days with topical and oral steroids, and her right eye orbital cellulitis and liver abscess resolved after she received intravenous ceftriazone. The aim of our reporting this case is to raise the issue that Klebsiella pneumonia is one of the causes of a pink hypopyon.
