Case Report: Corneal perforation secondary to orbital cellulitis caused by Streptococcus pseudoporcinus infection

Abstract

Introduction

This report described a rare case of corneal perforation secondary to orbital cellulitis caused by Streptococcus pseudoporcinus (S. pseudoporcinus) infection. To the best of our knowledge, only six cases of S. pseudoporcinus infection have been reported. This case report suggested that S. pseudoporcinus infection was contagious and potentially life threatening. The report emphasized the value of managing infections early to avoid serious consequences.

Case description

A patient with orbital cellulitis, which progressed to corneal perforation was admitted to the hospital for right facial swelling, pain, and decreased vision in his right eye. S. pseudoporcinus infection was found after bacterial culture of pus puncture. After aggressive anti-infection and surgical treatment, the infection was eliminated, and the patient was discharged. However, the patient had sustained permanent vision loss.

Conclusions

This case suggested the potential risk of corneal perforation and orbital cellulitis caused by S. pseudoporcinus infection in humans. The specific biological changes and mode of action of S. pseudoporcinus are unclear and need further investigation.
