RESUMO
Objetivo: Reportar dos casos de endoftalmitis endógena por Klebsiella pneumoniae hipermucoviscosa y revisar las características clínicas de esta entidad que ha aumentado su prevalencia en países occidentales. Observaciones: Dos pacientes fueron diagnosticados con endoftalmitis endógena por K. pneumoniae con confirmación microbiológica de un origen abdominal, uno de ellos por un absceso hepático y el otro por un absceso renal. Ambos pacientes fueron sometidos a vitrectomía precoz, y a antibióticos intravítreos/intravenosos, no obstante uno requirió evisceración y el otro presentó una agudeza visual de percepción de luz. Conclusiones e importancia: K. pneumoniae es la primera causa de endoftalmitis endógena en Asia oriental, pero es poco frecuente en los países occidentales. Sin embargo su prevalencia en esta última población parece estar aumentando en asociación con las variantes hipermucoviscosas e hipervirulentas de este microorganismo. La detección temprana y el tratamiento temprano de esta enfermedad son fundamentales para preservar la anatomía del ojo.
Objective: To report two cases of hypermucoviscous Klebsiella pneumoniae endogenous endophthalmitis and to review the clinical characteristics of this aggressive disease whose prevalence appears to be increasing in western countries. Observations: Two patients were diagnosed with K. pneumoniae endogenous endophthalmitis with microbiological confirmation of an abdominal source, one from a hepatic abscess and the other with a renal abscess. Both patients underwent early vitrectomy, and intravitreal/intravenous antibiotics, nonetheless one required evisceration and the other presented a postoperative visual acuity of light perception. Conclusions and importance: K. pneumoniae is the first cause of endogenous endophthalmitis in eastern Asia, but it is rare in western countries. Nevertheless, its prevalence in the latter population appears to be increasing in association with the hypermucoviscous and hypervirulent variants of this microorganism. The early detection and early management of this disease are pivotal to preserve the anatomy of the eye.

Despite being a common presenting symptom to eye-care clinics, many ophthalmologists have difficulty diagnosing and managing ocular surface pain. The purpose of this review is to discuss potential causes of ocular surface pain, focusing on both nociceptive and neuropathic aetiologies. Specifically, we outline an approach to the diagnosis of ocular surface pain and focus on various management strategies, providing supporting evidence on the efficacy of various treatments.
