[Vitreous cyst: a case presentation]. / Quiste vítreo: a propósito de un caso.

CASE REPORT: We report a case of a 12-year-old patient who complained about visual disturbances in left eye for 6 months. His visual acuity was 1/0.9, funduscopy in left eye revealed a free-floating cyst in the anterior vitreous. Magnetic resonance showed a low intense image in T1, and B-scan ultrasound confirmed a hypoechogenic cyst of 3.2 × 4.3 mm; ultrasound biomicroscopy revealed a normal ciliary body. CONCLUSION: Given the good VA the patient will be monitored periodically. If the cyst interferes with visual axis, management with Nd:YAG or Argon laser photocystotomy or remove it by pars plana vitrectomy has been advocated.

Quiste vítreo: a propósito de un caso / Vitreous cyst: a case presentation

Caso clínico: Presentamos el caso de un paciente de 12 años que refiere miodesopsias en ojo izquierdo (OI) de 6 meses de evolución. Presenta una agudeza visual (AV) de 1/0,9, en fondo de ojo izquierdo un quiste vítreo anterior. En la resonancia magnética se observa una imagen hipointensa en T1 y en la ecografía en modo B una lesión hipoecoica de 3,2×4,3 mm; la biomicroscopia ultrasónica puso de manifiesto un cuerpo ciliar normal. Conclusión: Dada la buena AV del paciente se observará periódicamente. Si interfiriese con el eje visual es posible fragmentarlo con láser Nd:YAG o argón, o bien su extracción vía pars plana(AU)

Cambios morfológicos maculares tras cirugía de cataratas: factores de riesgo / Morphological macular changes after cataract surgery: risk factors

Objetivos: Analizar cambios en la morfologíamacular tras cirugía no complicada de cataratas y sucorrelación con la edad y la hipertensión arterial.Métodos: Se realizaron medidas del volumenmacular total (TMV), volumen foveal (FOVOL) yespesor foveal (FOV) con OCT3 Stratus® enpacientes sometidos a cirugía de catarata antes de lacirugía, el día después y un mes después de la misma.Los datos fueron analizados utilizando SPSS15.0 software.Resultados: Se incluyeron 114 ojos de 114 pacientes.Los valores medios de TMV, FOVOL y FOV enel subgrupo con Signal Strength por encima de 6,antes de la cirugía de catarata fueron6,59 DE 0,67 μm3; 0,16 DE 0,02 μm3 and204,97 DE 29,79 μm. Un mes después de la cirugíade cataratas las mediciones fueron TMV:6,93 DE 0,56 μm3; FOVOL: 0,17 DE 0,06 μm3 yFOV: 218,07 DE 87,60 μm. Encontramos diferenciasestadísticamente significativas (P<0,05) en elvolumen macular total, no así en el espesor o volumenfoveal. El grupo de pacientes menores de 74años mostraron un mayor incremento en TMV. Lospacientes con hipertensión arterial no mostraron un mayor incremento en TMV ni FOV que aquellos sinhipertensión arterial.Conclusiones: Encontramos un edema macularsub-morfológico un mes después de la cirugía nocomplicada de cataratas, siendo la edad un factor deriesgo para desarrollar un mayor incremento enTMV. Por otro lado la hipertensión arterial no pareceser un factor de riesgo para que se produzcandichos cambios(AU)

Objective: To analyze morphological macularchanges after uncomplicated cataract surgery andtheir correlation with age and arterial hypertension.Methods: Total macular volume (TMV), fovealvolume (FOVOL) and foveal thickness (FOV) inpatients who had undergone cataract surgery weremeasured using OCT3 Stratus® before surgery, theday after the intervention and one month later. Thedata were analyzed using SPSS 15.0 software.Results: The study group was composed of 114eyes from 114 patients. The mean TMV, FOVOLand FOV in the subgroup of patients with signalstrength over 6 before cataract surgery were 6.59(SD0.67) μm3; 0.16 (SD0.02) μm3 and 204.97(SD29.79) μm. One month after surgery the measurementswere TMV: 6.93 (SD0.56) μm3; FOVOL:0.17 (SD0.06) μm3 and FOV: 218.07 (SD87.60)μm. We found statistically significant differences(P<0.05) in TMV, but not in FOVOL or FOV. Thegroup of patients under 74 years showed a greaterincrease in TMV. Patients with arterial hypertensiondid not show an increase in TMV or FOV comparedto patients without arterial hypertension. Conclusions: We found a sub-morphologicalmacular oedema one month after uncomplicatedcataract surgery, with age being a risk factor fordeveloping a greater increase in TMV. Arterialhypertension does not seem to be a risk factor forthese changes(AU)

[OCT in acute anterior uveitis]. / OCT en uveítis anteriores agudas.

PURPOSE: To evaluate macular thickening, the state of the optic disc and retinal nerve fibers layer (RFNL) in patients with an actual episode of acute anterior uvetis (AAU) by optical coherence tomography (OCT), and compare them with a control group. METHODS: In this prospective, cross-sectional, observational and controlled study we recruited 27 consecutive eyes of 20 patients with an actual episode of AAU, age and sex-matched with 40 healthy eyes of 20 volunteers. The age ranged between 8 and 78 years old, and all were evaluated by the <>, <> and <> scans by OCT. The patients were evaluated twice in a period of 1 month in order to obtain an average between the two measurements by OCT. RESULTS: We found a statistically significant increase in macular volume in AAU eyes compared with control eyes. Total macular volume in uveitic eyes was 7.3 SD 0.6 mm(3) and in healthy eyes was 7.01 SD 0.3 mm(3) (mean SD standard deviation) (p<0.001). Indeed, we found a statistically significant increase in the superior RFNL thickness compared with controls. The Smax/Imax measurement was 1.05 SD 0.1 in pathological eyes and in healthy eyes it was 0.97 SD 0.1 (p<0.02). CONCLUSION: We found by OCT that patients suffering an AAU showed an increase in macular volume and superior RFNL thickness versus control eyes in the acute episode.

Propósito: Evaluar el grosor macular, el estado delnervio óptico y de la capa de fibras nerviosas retinianas(CFNR) en pacientes con un episodio deuveítis anterior aguda (UAA) mediante OCT, ycomparar los resultados con un grupo control.Método: En este estudio prospectivo, transversal,observacional y controlado, reclutamos 27 ojos de20 pacientes con brote agudo de UAA, a los cualesse les empató por sexo y edad con 40 ojos de 20voluntarios sanos. El rango de edad de los pacientesfue 8-78 años, siendo evaluados mediante los scansde OCT ®fast macular thickness», ®fast optic disc»and ®fast RFNL thickness». Se hicieron dos medicionespor OCT a los pacientes, una al inicio y otraal mes del episodio, para obtener una medida promedio.Resultados: Encontramos un incremento en elvolumen macular estadísticamente significativo enlos ojos con UAA comparados con los ojos controles.El volumen macular total en los ojos con brotefue 7,3 DE 0,6 mm3 mientras que en los ojos controlesfue 7,01 DE 0,3 mm3 (p<0,001) (DE significadesviación estándar). Además, encontramos unaumento estadísticamente significativo en el grosorde las fibras del hemicampo superior de la CFNRcomparadas con las de los controles. El cociente Smax/Imax fue 1,05 DE 0,1 en los ojos patológicosy en los controles fue 0,97 DE 0,1 (p<0,02).Conclusiones: Encontramos que los pacientes quepresentaban un brote agudo de UAA tenían unincremento del volumen macular y del grosor de lacapa de fibras del hemicampo superior retinianocomparados con los ojos controles(AU)
