RESUMO

Citrobacter koseri is a bacillus that causes infrequent endophthalmitis. 6% of cultures in endophthalmitis are Gram -, and as in these, C. koseri is associated with a poor visual prognosis. We present a 65-year-old man who works in an animal laboratory. He went to emergencies with loss of vision in his left eye due to a vitreous hemorrhage. A vitrectomy was performed and 3 days later, endophthalmitis was diagnosed. Vancomycin and Ceftazidime were applied in eye drops and in two intravitreal injections. 24 h later he returned with a lens extrusion. Due to the severity of the condition, an evisceration was performed. Subsequently, the samples confirm the microorganism. We assume that the entry point for the bacterium was the sclerotomies through the exposed suture material, after handling rodent feces.

RESUMO

Las endoftalmitis asociadas a la ampolla de filtración tras cirugía filtrante de glaucoma son poco frecuentes, de inicio tardío y la mayoría están asociadas a una blebitis. Los agentes causales suelen ser estreptococos o bacterias gramnegativas. Existen pocos casos descritos en la literatura de endoftalmitis causada por Moraxella nonliquefaciens y la mayoría están asociados a una blebitis tras cirugía filtrante de glaucoma. Presentamos el caso de una paciente de 90 años con endoftalmitis en ojo derecho por Moraxella nonliquefaciens asociada a blebitis 10 años después de la cirugía de glaucoma. Tras el tratamiento, se observó la desaparición de la blebitis 2 semanas después y resolución de la vitritis 29 días después, con recuperación de la visión a valores previos (20/200). La endoftalmitis por Moraxella nonliquefaciens es rara y está asociada a blebitis de inicio tardío tras una cirugía filtrante de glaucoma. A pesar de la virulencia del cuadro, el pronóstico visual suele ser favorable


Bleb-related endophthalmitis is rare and appears months or years after surgery. The causative agents are usually streptococci or gram-negative bacteria. There are few cases in the literature of endophthalmitis caused by Moraxella nonliquefaciens, and most are delayed-onset associated with blebitis after glaucoma filtration surgery. The case is presented of a 90-year-old patient with endophthalmitis in the right eye due to Moraxella nonliquefaciens associated with blebitis 10 years after glaucoma surgery. After treatment, disappearance of blebitis is observed 2 weeks later and resolution of vitritis 29 days later, with recovery of vision to previous values (20/200). Endophthalmitis due to Moraxella nonliquefaciens is rare, and is associated with late onset blebitis after glaucoma filtration surgery. Despite the virulence of the clinical symptoms, the visual prognosis is usually favourable

RESUMO

La queratitis bacteriana por Moraxella spp. puede producir importantes complicaciones, siendo la producida por la Moraxella nonliquefaciens(M. nonliquefaciens) la de peor pronóstico. Solo existen tres publicaciones de queratitis por M. nonliquefaciens. Presentamos el caso clínico de un hombre de 79 años, con queratopatía bullosa, recientemente afectado con queratitis infecciosa grave. En la exploración se observa infiltrado estromal denso, profundo y central con hifema. Tras la identificación en cultivo de M. nonliquefaciens y dada la progresión se modifica el tratamiento empírico, según antibiograma, a ciprofloxacino y ceftazidima tópicos, asociando ciprofloxacino y amoxicilina clavulánico orales. Tras 27 días se aprecia resolución total de la lesión con leucoma residual central. La queratitis infecciosa por M. nonliquefaciens es rara y se debe sospechar en pacientes mayores con factores locales predisponentes como daño corneal o cirugía ocular previa. Es importante un tratamiento precoz guiado por antibiograma y un seguimiento cercano para evitar complicaciones y mal cumplimiento


Moraxella keratitis can lead to important complications. Moraxella nonliquefaciens(M. nonliquefaciens) has the worst prognosis. Only three cases of corneal infections due to M. nonliquefaciens have been published. The case is presented of a 79-year-old man with bullous keratopathy, recently affected with severe infectious keratitis. Dense, deep, and central stromal infiltrates and hyphaema were detected. After the identification of M. nonliquefaciens in the culture, and given the progression of the condition, the initial empirical treatment was modified to topical ciprofloxacin and ceftazidime in accordance with the antibiogram, combining oral ciprofloxacin and amoxicillin-clavulanate. After 27 days, there was total resolution of the lesion, with central residual leucoma. Keratitis caused by M. nonliquefaciens is rare and must be suspected in elderly patients with local predisposing factors, such as corneal damage or previous eye surgery. Early antibiogram-guided treatment and close monitoring are important to avoid complications and poor compliance

RESUMO

CASO CLÍNICO: Varón de 36 años consulta tras exposición bilateral a puntero láser el día anterior. En funduscopia se evidenciaron alteraciones pigmentarias maculares dispersas y en tomografía de coherencia óptica, desestructuración de las capas retinianas. La agudeza visual fue de contaje de dedos en ambos ojos. Nueve meses después se evidenció en la angiografía mediante tomografía de coherencia óptica una alteración del flujo vascular coriocapilar en la zona lesionada por el láser. Discusión: El láser afecta principalmente al epitelio pigmentario retiniano. Sin embargo, con este caso ponemos de manifiesto la posible afectación más allá del epitelio pigmentario retiniano, apareciendo alteración vascular coriocapilar tras la exposición a puntero láser


CASE REPORT: A 36-year-old man went to the emergency department the day after exposure to a laser pointer. Funduscopy revealed dispersed macular pigment alterations, and optical coherence tomography showed a disruption of the retinal layers. The visual acuity was counting fingers in both eyes. Nine months later, optical coherence tomography angiography showed a rarefaction in the choriocapillaris vascular flow in the area of the laser injuries. DISCUSSION: The retinal layer mainly damaged by the laser injury was the retinal pigment epithelium. However, it is suggested that the laser injury could involve tissues beyond the retinal pigment epithelium, since a rarefaction of the choriocapillaris was found after exposure to the laser

RESUMO

CASO CLÍNICO: Mujer de 81 años en tratamiento con una combinación fija de timolol y brimonidina en colirio que fue diagnosticada en urgencias de uveítis anterior aguda hipertensiva granulomatosa. La paciente respondió favorablemente a la retirada del colirio sin mostrar recaída posterior. DISCUSIÓN: La uveítis por brimonidina es un efecto adverso raro, pero que debe ser conocido. Una vez se llega al diagnóstico de sospecha, el tratamiento efectivo es la retirada del colirio de brimonidina, con adición o no de corticoides tópicos para controlar la inflamación según la gravedad del cuadro. Se trata de un proceso con un pronóstico excelente


CLINICAL CASE: The case concerns an 81-year-old woman on treatment with a topical fixed combination of timolol and brimonidine who was diagnosed in the Emergency Department with acute anterior granulomatous hypertensive uveitis. The patient responded favourably to the withdrawal of the eye drops without showing any subsequent relapse. DISCUSSION: Uveitis due to brimonidine is a rare adverse effect, but it must be known. Once the diagnosis is suspected, the effective treatment is the withdrawal of brimonidine, with or without the addition of topical corticosteroids to control inflammation depending on the severity of the condition. It is a process with an excellent prognosis

RESUMO

CASO CLÍNICO: Presentamos un caso de osteoma de coroides unilateral con excavación coroidea y membrana neovascular asociada estudiado mediante angiografía-TCO. En TCO y angiografía-TCO se objetivó excavación coroidea y una membrana neovascular coroidea activa. Se administraron tres dosis de aflibercept estabilizando la neovascularización coroidea. DISCUSIÓN: La angiografía-TCO permitió el análisis morfológico de la red vascular superficial del osteoma así como el control evolutivo de la membrana neovascular


CLINICAL CASE: A case is presented of a unilateral choroidal osteoma with choroidal excavation and associated neovascular membrane that was studied using OCT-angiography. The OCT and OCT-angiography revealed an area of choroidal excavation and an active neovascular membrane. Three doses of aflibercept were administered to the patient, which stabilised the neovascularisation. DISCUSSION: OCT-angiography was used to analyse the morphology of the superficial vascular network of the osteoma, as well as to monitor the evolution of the neovascular membrane
