Abstract
BACKGROUND

Streptococcus mitis (S. mitis) is an opportunistic pathogen that can lead to severe ocular infections. In previous reports, penetrating keratoplasty (PK) was usually adopted for the treatment of persistent corneal ulcers. This report describes an unusual case of nonhealing descemetocele caused by S. mitis treated by antibiotics plus amniotic membrane transplantation (AMT).

CASE SUMMARY

A 63-year-old woman presented with a right persistent corneal ulcer that she had suffered from for the past 9 mo. The culture of a corneal scraping yielded S. mitis. The right eye descemetocele decreased in diameter from 3 to 0.8 mm after the continuous administration of topical vancomycin and ceftriaxone for 2 wk. Due to the slow healing, AMT was performed. Her corneal erosion healed and gradually became clear. Her visual acuity recovered from initially counting fingers to 100/200 at the last follow-up, 67 mo after AMT.

CONCLUSION

Antibiotics plus AMT may be an effective alternative treatment other than PK to promote epithelialization and to reduce inflammation in the corneas complicated by S. mitis keratitis.

Keywords: Persistent corneal ulcer, Amniotic membrane transplantation, Streptococcus mitis, Case report

Core Tip: In this case, we described the clinical and treatment course of an impending perforated corneal ulcer caused by Streptococcus mitis (S. mitis). We also demonstrated that treatment with antibiotics and amniotic membrane transplantation was successful, without the need for penetrating keratoplasty, and this could be considered an alternative treatment for nonhealing descemetoceles induced by S. mitis, as compared to the previous treatment.
