**9. Visual outcome**

In most cases of Infection arising from gram-negative pathogens and streptococci, there is a worse visual prognosis, with only 45–46% achieving best visual acuity (BVA) ≥20/400. In contrast, 89% of eyes achieve BVA ≥20/400 following Infections associated with coagulase-negative staphylococci [78].

Better visual outcomes after BRE are associated with the following:

shorter interval from onset of symptoms to treatment, better initial visual acuity, clear cornea at presentation, isolation of less virulent organisms, and absence of diabetes mellitus [34, 79].
