| Summary: | Purpose: To describe the clinical course and microbial properties of the first two reported cases of nutritionally variant Streptococci (Granulicatella adiacens and Abiotrophia defectiva) endophthalmitis following intravitreal anti-vascular endothelial growth factor injection (IVI). Observations: A 74 year-old female developed Granulicatella adiacens endophthalmitis following IVI. The patient underwent a pars plana vitrectomy and visual acuity recovered to 20/30 in six weeks. Similarly, an 88 year-old male developed Abiotrophia defectiva endophthalmitis after IVI. After a pars plana vitrectomy, the visual acuity recovered to 20/60 at five weeks. Conclusions and Importance: Endophthalmitis due to Streptococcus species has traditionally resulted in uniformly poor visual outcomes. However, nutritionally variant Streptococci, now reclassified as Granulicatella and Abiotrophia species, appear to have a less aggressive clinical course and better visual acuity outcomes. To the authors’ knowledge, these are the first reports of nutritionally variant Streptococci following IVI related endophthalmitis.
