Abstract
Objective

To assess the rate of endophthalmitis after intravitreal injection (IVI) in a “clean room” of a single health center, following the guidelines of the Spanish Vitreo-Retinal Society (SERV). An analysis was performed on the culture specimens, response to treatment, and final outcomes (guidelines).

Material and methods

A retrospective, observational study was conducted on a consecutive case series of patients diagnosed with infectious endophthalmitis after IVI in a single health center between 2010 and 2015. Intravitreal and systemic treatment was given following the SERV guidelines. The patients were followed up the case was resolved.

Results

There were 5 cases of endophthalmitis out of 9467 IVI (incidence 0.053%). Positive cultures were obtained in aqueous and/or vitreous fluid in all cases, with Staphylococcus epidermidis being involved in 4 out of 5 cases. In 2 cases, final visual acuity was non-light perception due to intractable retinal detachments after resolution of the infectious process.

Conclusions

IVI performed in a “clean room” have a low incidence of endophthalmitis. The most common infectious agent was Staphylococcus species. In 2 cases the functional prognosis was poor.

Resumen
Objetivo

Averiguar la incidencia de la endoftalmitis tras inyecciones intravítreas (IVT) en «sala limpia» de un centro terciario, siguiendo los protocolos de la Sociedad Española de Retina y Vítreo (SERV). Identificar agentes causales, observar la respuesta al tratamiento y el resultado funcional final.

Material y métodos

Estudio retrospectivo, observacional, en una serie de casos clínicos, de las endoftalmitis tras IVT realizadas en nuestro centro entre 2010 y 2015. En estos casos, se efectuó tratamiento intravítreo y sistémico, siguiendo las pautas de la SERV, así como una vitrectomía diagnóstico-terapéutica, con seguimiento hasta la resolución definitiva del caso.

Resultados

Se produjeron 5 casos de endoftalmitis en 9.467 IVT (incidencia 0,053%). Se obtuvieron muestras de acuoso o vítreo, con cultivo positivo en todos los casos: Staphylococcus epidermidis fue el principal agente causal en 4 de los 5 casos. En 2 casos la agudeza visual fue de no percepción luminosa por desprendimiento de retina irreductible tras la resolución del proceso infeccioso.

Conclusiones

Las IVT realizadas en «sala limpia» tiene una baja incidencia de endoftalmitis: la especie Staphylococcus es la responsable más frecuente. Dos de los casos acabaron con un mal pronóstico funcional.
