Wickerhamomyces Anomalus Postoperative Endophthalmitis.

INTRODUCTION: We describe the case of a postoperative fungal endophthalmitis caused by Wickerhamomyces anomalus, an opportunistic yeast common in nature but rare as a causative agent in ocular infections. This would be the second reported case of W. anomalus endophthalmitis. CASE REPORT: A patient came to our hospital with a dense hemovitreous caused by an inadvertent ocular perforation and retinal detachment during a cataract surgery. In the days following the first vitreoretinal surgery a chronic postoperative endophthalmitis was evidenced. Only after several surgeries as well as intravitreal antibiotics and sample takings, Wickerhamomyces was detected. The treatment with oral voriconazole and an intraocular lens extraction controlled the infection. DISCUSSION: Wickerhamomyces anomalus, despite not being particularly aggressive in our case, was resistant to various consequent vitreoretinal surgeries. The unresponsiveness to treatment led us to contemplate the fungal etiology, and fortunately the cultures were positive for this yeast. In conjunction to antifungal therapy, it is possible that the IOL explantation played an important role in the treatment. CONCLUSION: A high index of suspicion must be held in cases of fungal endophthalmitis. Both IOL explantation and oral antifungal therapy are useful treatment options in cases of W. anomalus endophthalmitis.

Clostridium Septicum Endogenous Endophthalmitis as the Initial Manifestation of Colorectal Carcinoma: Clinical Case Report and Literature Review.

PURPOSE: To describe the presentation and clinical course of a case of endogenous endophthalmitis caused by Clostridium septicum, an anaerobic and gram positive bacteria. METHODS: Observational report of a clinical case presented in Spain. CLINICAL CASE: A 61-year-old male patient was referred to our hospital with a diagnosis of endophthalmitis of his left eye since ten days prior to presentation, and a history of poor response to medical treatment. Evisceration was performed, and C. septicum was isolated from a sample of the vitreous humor. Fourteen days after surgery, the patient returned with orbital cellulitis, and exenteration was performed. Forty-two days after initial presentation, colonoscopy revealed an adenocarcinoma of the proximal colon. Surgical resection of the tumor was performed, and clinical recovery was achieved. CONCLUSIONS: iSystemic C. septicum infection without a traumatic cause has been associated with malignancy, although an initial presentation of endophthalmitis has rarely been reported. In cases of clostridial endogenous endophthalmitis, investigation for colorectal carcinoma is indicated.
