Abstract
Introduction
Endophthalmitis is a severe, vision-threatening intraocular infection that may follow various ophthalmic surgeries, with varying microbial etiologies. Abiotrophia defectiva, a less commonly implicated pathogen, is better recognized for its association with endocarditis rather than intraocular infections.
Case presentation
A 50-year-old man was diagnosed with endophthalmitis after trabeculectomy for open-angle glaucoma. In the outpatient clinic, he had visual acuity of 20/160, conjunctival congestion, mild anterior chamber inflammation, and preretinal bleeding. In the hours that followed, the condition worsened dramatically. He underwent urgent anterior chamber irrigation, vitreous tap, and intravitreal injection. As the symptoms did not improve, a vitrectomy was performed. The results of postoperative culture were positive for Abiotrophia defectiva. After timely and effective treatment, the patient's visual acuity increased to 20/125. At a one-year follow-up, the patient's visual acuity improved to 20/32.
Conclusion
This report delineates a rare case of endophthalmitis caused by Abiotrophia defectiva following trabeculectomy, emphasizing the need for prompt recognition and treatment of atypical pathogens in postoperative ocular infections to enhance visual outcomes.
