Abstract
BACKGROUND: Endophthalmitis, a potentially sight-threatening condition, remains a challenge for ophthalmologists worldwide. The endophthalmitis vitrectomy study (EVS) conducted in 1995 compared vitrectomy and intravitreal antibiotic injections to intravitreal antibiotic injections alone for acute post-cataract surgery and secondary intraocular lens endophthalmitis, setting treatment guidelines. However, the landscape of clinical practice has evolved considerably since then, raising questions about the applicability of EVS recommendations today. SUMMARY: Recent studies have proposed that early and complete vitrectomy (CEVE) could potentially be an effective approach for managing endophthalmitis cases, irrespective of the initial visual acuity. However, it is important to note that the level of rigor in these recent studies may not match that of the EVS study, and as such, this assertion should be considered with caution. Furthermore, the EVS study exclusively focused on post-cataract surgery cases, leaving other endophthalmitis types, like post-intravitreal injection and post-traumatic endophthalmitis, without standardized treatment guidelines. Research exploring the role of early vitrectomy in these contexts yields mixed results, emphasizing the need for further investigation and well-designed prospective trials. Endogenous endophthalmitis, originating from systemic infections, adds complexity to the scenario. While early vitrectomy shows promise in specific cases, conflicting evidence necessitates comprehensive research. KEY MESSAGES: This review underscores the necessity for tailored treatment strategies, supporting early vitrectomy when clinically indicated, and advocating for prospective trials to clarify its role in diverse endophthalmitis scenarios. As surgical techniques and antimicrobial therapies continue to advance, reevaluating treatment paradigms becomes crucial to enhance patient outcomes and protect ocular health.
