Purpose: To report a case of late-onset bleb-associated endophthalmitis caused by streptococcus cristatus (S. cristatus) after trabeculectomy.
Case summary: A 59-year-old woman presented with left ocular pain and visual disturbance. She had undergone trabeculectomy of the left eye 2 years ago. At the initial visit, she was only able to count fingers from the left eye. Whitish thin bleb, conjunctival injection, and inflammation were observed in the left anterior chamber, and the fundus could not be visualized. Despite administering topical and systemic antibiotics, the chamber reaction worsened, and hypopyon and inflammatory membrane were noticed the next day. Vitrectomy with phacoemulsification and intravitreal antibiotic injection was performed, and the intravitreal antibiotic injections were repeated over the next two days. Bacterial culture of vitreous fluid showed a growth of S. cristatus 5 days after the surgery, and inflammation improved after 7 days. One month later, she was still only able to count fingers from the left eye, but there were no signs of endophthalmitis.
Conclusions: Postoperative endophthalmitis after glaucoma filtering surgeries caused by S. cristatus has not been reported previously from Korea. To the best of our knowledge, this is the first Korean case of late-onset bleb-associated endophthalmitis caused by S. cristatus. If gram-positive cocci are grown in samples from the patients with endophthalmitis after trabeculectomy, resident oral microflora such as S. cristatus should be considered as the causative pathogen.
