RESUMO

Antecedentes y objetivo El objetivo es analizar la densidad vascular (DV) coroidea en individuos sanos y compararla con el grosor coroideo (GC). Materiales y métodos Estudio transversal incluyendo individuos entre 18 y 35 años, caucásicos y con longitud axial (LA) 21-26 mm. Se estudió la coroides con tomografía de coherencia óptica-angiografía (OCTA) Triton DRI (Topcon) y se obtuvo un cubo macular de 6x6 mm. El software dio los valores de GC automáticamente. Los valores de DV se obtuvieron mediante codificación en números de los colores de los mapas de DV. Resultados Se analizaron 102 ojos (51 pacientes). La edad media fue 27,32 ± 3,94 años, la presión intraocular media fue 18,07 ± 2,38 mmHg, y la LA media fue 23,71 ± 0,66 mm. El GC fue mayor en el eje vertical y menor al acercarse a los lados nasal y temporal. El mayor GC se encontró en la mácula superior. La mayor DV coroidea fue en la fóvea y en la región yuxtapapilar. La menor DV coroidea se halló en la mácula superior e inferior. Se encontraron correlaciones moderadas inversas entre GC y DV coroidea en las regiones yuxtapapilar e inferior. Conclusiones La coroides tiene un patrón de grosor diferente del de la retina. Los vasos coroideos representan un porcentaje muy alto de la coroides en las regiones peripapilar y fóvea. Por el contrario, la mácula superior e inferior muestra valores bajos de DV (AU)


Background and purpose The purpose is to analyze choroidal vascular density (VD) in healthy individuals and to compare it with choroidal thickness (CT). Materials and methods Cross-sectional study enrolling healthy individuals between 18 and 35 years old of Caucasian race and with an axial length (AL) 21–26 mm. Choroid was imaged with swept-source optical coherence tomography angiography (OCTA) Triton DRI (Topcon) and a macular cube of 6 mm × 6 mm was obtained. CT values were automatically given by the software. VD values were obtained through codifying colors of the VD map into numbers. Results One hundred and two (51 patients) were analyzed. Mean age was 27.32 ± 3.94 years old, mean intraocular pressure was 18.07 ± 2.38 mmHg, and mean AL was 23.71 ± 0.66 mm. CT was higher in the vertical axis and lower when approaching nasal and temporal sides. The highest CT was in superior macula. The highest choroidal VD were in the fovea and in the juxtapapillary region. The lowest choroidal VD were found in superior and inferior macular areas. Moderate inverse correlations between CT and choroidal VD were found in the juxtapapillary and inferior regions. Conclusions The choroid has a thickness pattern that differs from retina. Choroidal vessels represent a very high percentage of choroid in the peripapillary region and in the fovea. On the contrary, superior and inferior macula reveals low values of VD (AU)

MATERIALS AND METHODS: Cross-sectional study enrolling healthy individuals between 18 and 35 years old of Caucasian race and with an axial length (AL) 21-26 mm. Choroid was imaged with swept-source optical coherence tomography angiography (OCTA) Triton DRI (Topcon) and a macular cube of 6 × 6 mm was obtained. CT values were automatically given by the software. VD values were obtained through codifying colors of the VD map into numbers. RESULTS: 102 (51 patients) were analyzed. Mean age was 27.32 ±â€¯3.94 years old, mean intraocular pressure was 18.07 ±â€¯2.38 mmHg, and mean AL was 23.71 ±â€¯0.66 mm. CT was higher in the vertical axis and lower when approaching nasal and temporal sides. The highest CT was in superior macula. The highest choroidal VD were in the fovea and in the juxtapapillary region. The lowest choroidal VD were found in superior and inferior macular areas. Moderate inverse correlations between CT and choroidal VD were found in the juxtapapillary and inferior regions. CONCLUSIONS: The choroid has a thickness pattern that differs from retina. Choroidal vessels represent a very high percentage of choroid in the peripapillary region and in the fovea. On the contrary, superior and inferior macula reveals low values of VD.

RESUMO

Introducción: El melanoma uveal, es el cáncer intraocular más común en adultos, representa cerca del 3 % al 5 % de todos los melanomas; con un pico de incidencia en hombres en la sexta década de la vida. Objetivo: Describir la presentación clínica, diagnóstico y tratamiento de una paciente con melanoma uveal. Caso clínico: Paciente femenina de 39 años de edad, con antecedentes de salud, quien acudió a consulta por presentar dolor intenso de doce días de evolución localizado en el ojo derecho, asociado a pérdida de la visión, dolor a los movimientos oculares, astenia y anorexia. Al examen físico se encontró edema palpebral severo, abundantes secreciones mucopurulentas, quémosis conjuntival en 360 grados marcado e hiperemia cilio-conjuntival en el ojo derecho. Se realizaron estudios analíticos e imagenológicos. Al analizar el resultado de la exploración física y los complementarios se decidió la intervención quirúrgica consistente en la exenteración orbitaria derecha, esfenoidectomía y etmoidectomía transorbitaria derecha. Con una evolución satisfactoria fue egresada del centro hospitalario. La biopsia informó un melanoma coroideo. Conclusiones: El melanoma coroideo es una enfermedad ocular poco frecuente en mujeres jóvenes de piel negra. La sintomatología es extremadamente variable con las masas coroideas. Es importante conocer sus características, pues estos efectos clínicos sirven como un recordatorio para los oftalmólogos para incluirla en el diagnóstico diferencial de otras patologías oculares.


Introduction: Uveal melanoma is the most common intraocular cancer in adults, represents approximately 3 % to 5 % of all melanomas; with a peak incidence in men in the sixth decade of life. Objective : To describe the clinical presentation, diagnosis and treatment of a patient with uveal melanoma. Clinical case: A 39-year-old female patient, with a health history, who came to the consultation due to intense pain of twelve days of evolution located in the right eye, associated with loss of vision, pain with eye movements, asthenia and anorexy. Physical examination revealed severe palpebral edema, abundant mucopurulent secretions, marked 360-degree conjunctival chemosis, and cilio-conjunctival hyperemia in the right eye. Analytical and imaging studies were performed. When analyzing the results of the physical and complementary examination, the surgical intervention consisting of right orbital exenteration, sphenoidectomy and right transorbital ethmoidectomy was decided. With a satisfactory evolution, she was discharged from the hospital. Biopsy reported choroidal melanoma. Conclusions: Choroidal melanoma is a rare ocular entity in young black women. Symptomatology is extremely variable with choroidal masses. It is important to know its characteristics, since these clinical effects serve as a reminder for ophthalmologists to include it in the differential diagnosis of other ocular pathologies.

RESUMO

En la actualidad se cuenta con escasos reportes de casos clínicos de pacientes con metástasis coroidea sintomática como la presentación inicial de cáncer de pulmón. En este reporte describimos el caso de una paciente con adenocarcinoma de pulmón, la cual fue diagnosticada por síntomas iniciales oculares consistentes en pérdida visual progresiva y presencia de escotomas en ambos ojos, por lo que se le realizaron exámenes adicionales que llevaron al diagnóstico de cáncer de pulmón con metástasis coroidea. El pronóstico de estos pacientes es pobre, en la mayoría de los casos se trata de tumores en estadios avanzados de la enfermedad.


Currently there are few clinical case reports of patients with symptomatic choroidal metastasis as the initial presentation of lung cancer. In this report, we describe the case of a female patient with lung adenocarcinoma, who was diagnosed due to initial ocular symptoms consisting of progressive visual loss and the presence of scotomas in both eyes, so additional tests were performed leading to the diagnosis of lung cancer with choroidal metastasis.

RESUMO

Objetivo: Describir las características clinicopatológicas de los pacientes con diagnóstico de melanoma de la úvea. Métodos: Se realizó un estudio descriptivo y retrospectivo de serie de casos, en el Instituto Cubano de Oncología y Radiobiología de Cuba, desde enero del año 2011 hasta junio de 2016. El universo del estudio, en coincidencia con la muestra, estuvo constituido por 41 pacientes, el total de ellos diagnosticado y tratado en dicho período por melanoma uveal. Se estudiaron las variables edad, sexo, lateralidad, localización y tamaño tumoral, clasificación, tipo celular, grado de invasión y tratamiento. Resultados: El 56,1 por ciento de la muestra fue del sexo femenino. Los pacientes mayores de 50 años (75,6 por ciento) fueron los más afectados y el ojo izquierdo fue el más vulnerable (58,5 por ciento). La principal localización fue en la coroides (75,6 por ciento). Según el tamaño tumoral predominaron los tumores grandes (58,5 por ciento); histológicamente el tipo celular más frecuente fue el de células fusiformes (34,2 por ciento); según el grado de invasión, la más afectada fue la esclera (17,0 por ciento) y como único tratamiento practicado la enucleación (100 por ciento). Conclusiones: El melanoma de la úvea tiene su localización más frecuente en la coroides. Se presenta principalmente en pacientes mayores de 50 años y predominan los tumores grandes(AU)


Objective: To describe the clinical and pathological characteristics of patients diagnosed with uveal melanoma. Methods: A retrospective, descriptive and case series study was performed from January 2011 to June 2016 in the Institute of Oncology and Radiobiology of Cuba (INOR). The universe of study was the sample of 41 patients, all of them diagnosed with uveal melanoma and treated in this period of time. The study variables were age, sex, laterality, tumor location and tumor, classification, cell type, degree of invasion and treatment. Results: Females accounted for 56.1 percent of the sample. The patients aged 50 years or over (75.6 percent) were the most affected whereas left eye was the most vulnerable (58.5 percent). The main location were the choroids (75.6 percent) According to size, the large tumors predominated (58.5 percent); from the histological viewpoint, the most common cell-type was fusiform cell tumor (34.2 percent); according to the degree of invasion, the sclera was the most affected (17 percent) and the only treatment was enucleation. Conclusions: Uveal melanoma is more frequently located in the choroids. It mainly appears in patients aged over 50 years and most of tumors are large(AU)

RESUMO

OBJECTIVE: To describe the ultrasound, histopathological and genetic characteristics of uveal melanoma in a Mexican-Mestizo population. MATERIAL AND METHODS: A total of 39 enucleated eyes with a histopathological diagnosis of uveal melanoma were assessed by describing the clinical findings, and ultrasound, histopathological and genetic features. RESULTS: A high correlation was observed between tumour height measurement using ultrasound and histopathology. In our cases, tumour size and reflectivity were higher compared with those reported in the literature. The preliminary data on the molecular assessment of the tumours show the presence of an unreported polymorphism (T>C IVS5+34) and one sample with GNAQ mutation (A>C CAA>CCA Gln 209 Pro). CONCLUSION: Ultrasound is a reliable method to identify the size of the tumour. Furthermore, knowledge of the molecular mechanisms promises new perspectives for the development of new targeted therapeutics. Fortunately this leads to progress in the treatment of patients with metastatic disease or prevents it in those at high risk.

RESUMO

El melanoma maligno de coroides es el tumor intraocular primario más frecuente en la edad adulta. Su evolución clínica es muy variable y constituye un peligro potencial para la vida de las personas afectadas. Se presenta el caso de un paciente de 42 años, caucásico, de procedencia urbana que acudió al Centro Oftalmológico de Holguín por disminución lenta y progresiva de la visión de aproximadamente hacía dos años de evolución que inicialmente comenzó como un defecto del campo visual periférico hasta afectar la visión central. La oftalmoscopía mostró lesión tumoral yuxtapapilar de coloración pardo-grisácea, elevada en forma de hongo, que produjo desprendimiento de retina secundario en tienda de campaña. Fue diagnosticado como portador de un melanoma maligno de coroides y remitido al Instituto Nacional de Oncología y Radiobiología donde se le realizó la enucleación del ojo derecho y se confirmó el diagnóstico por anatomía patológica. Se discutieron los principales factores de riesgo, la forma clínica de presentación, los hallazgos en las investigaciones clínicas realizadas para el diagnóstico, la modalidad de tratamiento aplicada, la evolución y el pronóstico, a partir de la información recogida de la revisión del expediente clínico del paciente.(AU)


Choroidal malignant melanoma is the most frequent intraocular tumor in adults. Its clinical evolution is very variable and it is a potential hazard for the life of the affected people. The case of a 42-year-old Caucasian urban male patient is reported. The patient presented to the Ophthalmological Center of Holguín complaining of slow and progressive loss of vision of about 2-years´ evolution that initially began as a peripheral visual field defect up to affect central vision. The ophthalmoscopy showed an elevated grayish-brown-colored mushroom-shaped tumoral lesion next to the papilla that produced a secondary tent-like retinal detachment. He was diagnosed as carrier of choroidal malignant melanoma and was referred to The National Institute of Oncology and Radiobiology where the enucleation of his righ eye ball was performed and the diagnosis was confirmed through pathological study. The main risk factors, clinical presentation, clinical research findings for diagnosis, treatment, evolution and prognosis were discussed from the information obtained from his clinical record.

RESUMO

La atrofia gyrata de coroides y retina fue descrita por vez primera por Fuchs en el año 1896 como una entidad clínicamente definida. La deficiencia de la enzima ornitina delta aminotransferasa se hereda de forma autosómica recesiva; resulta en incremento plasmático de las concentraciones de ornitina y se asocia con atrofia gyrata de coroides y retina. Se presenta una paciente de 6 años de edad que es llevada a consulta, ya que en la escuela la maestra notaba mala visión de lejos. En un examen inicial del fondo de ojo el oftalmólogo observó cambios sugestivos de distrofia retiniana. En la oftalmoscopia binocular indirecta se encontraron extensas zonas confluentes de atrofia coroidea por fuera de las arcadas vasculares que respetaban el polo posterior; la mácula impresionaba normal. Se realizó un estudio de tomografía de coherencia óptica en dominio espectral en tomógrafo Spectralis que demostró la presencia de edema macular cistoide en ambos ojos. La determinación de niveles de ornitina en sangre arrojaron niveles muy elevados de este aminoácido (975 µmol/mL). Con todos estos hallazgos se llegó al diagnóstico de hiperornitinemia y atrofia gyrata de coroides y retina. Se indicó tratamiento dietético y vitamina B6 oral a pesar de que no se ha obtenido hasta el momento reducción significativa de los niveles de ornitina en plasma(AU)


Gyrate atrophy of the choroid and the retina was first described by Fuchs as a clinically defined condition in 1896. Human hereditary deficiency of ornithine aminotransferase activity is transmitted as an autosomal recessive trait and results in increased level of plasma ornithine and is associated with gyrate atrophy of the choroid and the retina. A 6-year-old girl was taken to the ophthalmologist’s because of her far poor vision detected by her teacher at the school. In the initial eye fundus examination the ophthalmologist observed some changes indicating retinal dystrophy. The indirect binocular funduscopy revealed extensive areas of choroidal atrophy outside the vascular archades respected the posterior pole whereas the macula impressed as normal. Cystoid macular edema was evident in both eyes according to the results of the optic coherence tomography performed with Spectralis tomograph. The aminoacid analysis revealed high serum ornithine level (975 µmol/mL). The clinical diagnosis of the patient was consistent with hyper-ornithinemia and gyrate atrophy of the choroid and the retina. She was treated with vitamin B6 and dietary supplementation but no significant reduction on her serum ornithine level was observed(AU)

RESUMO

Choroidal hemangioma is a rare congenital ocular tumor that can present as either circumscribed or diffuse. Circumscribed choroidal hemangioma (CCH) typically manifests as a red-orange mass within the posterior pole and appears similar to other ocular conditions, such as choroidal melanoma and choroidal metastasis. Proper diagnosis is crucial and is aided by the use of ancillary testing. CCH itself is benign but can cause secondary complications such as subretinal fluid accumulation and subsequent retinal detachment. If these conditions should arise, several treatment options are available.

RESUMO

El melanoma maligno de coroides es el tumor intraocular primario más frecuente en adultos entre 40 y 60 años, siempre es maligno, afectando un solo ojo; su crecimiento es rápido, generalmente es fatal en pocos años, si no es diagnosticado y tratado a tiempo el paciente. Se presenta el caso de una paciente femenina de 54 años de edad, que acude a la consulta de retina por alteración en la visión de confusión de los colores; de varios meses de evolución. Se le realizó estudio de oftalmoscopia indirecta, que confirmó el diagnóstico etiológico de melanoma maligno de coroides. Se toma la decisión de realizar la enucleación en ojo izquierdo, la paciente evolucionó favorablemente (AU)


Choroidal malignant melanoma is the most frequent primary intraocular tumor in adults between 40 and 60 years old; it is always malignant, affecting only one eye; it grows quickly; if the patient is not early diagnosed and treated, it will usually be fatal in a few years. This is the case of a 54-year-old female patient, who comes to the retina specialized consultation due to an alteration in her color vision with several months of evolution; accordingly, she underwent indirect ophthalmoscopy studies, which confirmed the etiological diagnosis of choroidal malignant melanoma. Enucleation of her left eye was decided, and consequently the patient progressed favorably (AU)

RESUMO

PURPOSE: To compare subfoveal choroidal thickness (GCSF) in patients with diabetic macular oedema (DMO) and healthy subjects using swept source optical coherence tomography (SS-OCT). METHOD: Cross-sectional study including 50 eyes of 36 patients with DMO, and 47 eyes of 34 patients as a control group. GCSF was measured in both groups, analysing between the eyes with DMO according to the type of oedema (predominantly cystic or diffuse). RESULTS: The study groups were homogeneous in terms of mean age (63.4 years for DMO and 62.65 years for controls; P=.36) and the mean axial length (23.21mm for DME and 23.53mm for controls; P=.06). A statistically significant reduction in the eye with DME GCSF compared to controls (P=.041, 222.9 vs. 192.82 µm) was observed. No statistically significant differences were observed in the eyes with DMO with a predominantly cystic pattern and diffuse oedema (P=.13, 178.68 vs. 205.7 µm). CONCLUSION: The GCSF in patients with DMO could be reduced. Future studies are needed to confirm these preliminary results.

RESUMO

OBJECTIVE: To analyse macular choroidal thickness (MCT) in non-arteritic ischaemic optic neuropathy (NAION). MATERIALS AND METHODS: An analysis was made on 22 patients diagnosed with NAION (22 eyes) and 42 healthy controls (42 eyes) using enhanced-depth imaging of spectral-domain optical coherence tomography. A horizontal raster scan centred on the fovea was obtained per eye 3 months after the onset of NAION. Three measurements of MCT were obtained from the posterior edge of the retinal pigment epithelium to the choroid-sclera junction at 500µm intervals. Statistical analysis was used to compare the mean MCT and to correlate MCT with other ocular and systemic parameters. RESULTS: Except for refractive error (P=.01), there were no statistically significant differences between both groups in axial length (P=.53), age (P=.88) and other epidemiological and ocular parameters. Mean MCT in NAION eyes and control group was 236.21±63.29µm and 269.13±52.28, respectively. Mean MCT was significantly thinner in NAION eyes than in healthy eyes (P=.03). Thinner MCT, adjusted for refractive error, was associated with the diagnosis of NAION (P=.04). CONCLUSIONS: Eyes affected by NAION showed significantly thinner MCT compared with healthy control eyes after adjusting for refractive error.

RESUMO

Objetivo: reportar tres casos de pacientes con hemangioma de coroides tratados con terapia fotodinámica (TFD) y realizar una revisión de la literatura sobre el tema. Diseño del estudio: estudio retrospectivo intervencionista, tipo serie de casos. Pacientes y metodología: revisión de historias clínicas y de exámenes complementarios de 3 pacientes con diagnóstico de hemangioma de coroides pre y post tratamiento con TFD en la Fundación Oftalmológica Nacional. Resultados: de los 3 casos presentados, dos se presentaron como hemangiomas de coroides circunscritos y uno difuso en un paciente con síndrome de Sturge ­ Weber. En todos los casos se observó mejoría de la agudeza visual, resolución del desprendimiento seroso de retina y regresión del tumor, sin efectos secundarios a la TFD. Conclusiones: el hemangioma coroideo es una patología con una baja incidencia, de evolución variable y difícil de predecir. La terapia fotodinámica es una alternativa no invasiva, de elección para hemangiomas coroideos sintomáticos, ya que no produce daño a las estructuras vecinas y presenta pocos efectos colaterales.


Objective: to report three cases of patients with choroidal hemangioma treated with photodynamic therapy (PDT) and review of the literature. Study design: retrospective interventional study, cases reports. Patients and methods: review of medical records and ancillary tests were performed in 3 patients with choroidal hemangioma pre and post PDT treatment. Results: of the 3 cases reported, two had a circumscribed choroidal hemangioma and one a diffuse hemangioma associated with Sturge ­ Weber syndrome. All cases had improvement in visual acuity, resolution of serous retinal detachment and tumor regression without PDT side eff ects after follow-up. Conclusions: choroidal hemangiomas have a low incidence and an uncertain prognosis. Photodynamic therapy remains as a noninvasive alternative for symptomatic choroidal hemangiomas, without damage to surrounding structures and few side effects.

RESUMO

La degeneración macular de Stargardt es considerada una enfermedad rara pues se presenta un caso por cada 10.000 personas (1).Es de transmisión hereditaria de un patrón autosómico recesivo. Está provocada por una mutación del gen ABCA4, que tiene una función transportadora a través de la membrana de las células fotorreceptoras. Hay 558 mutaciones diferentes que pue-den originar el mal (2).La enfermedad Stargardt y Fundusflavima-culatus son la misma enfermedad, siendo el segundo, un estado más avanzado de almacenamiento de lipofucsina (3).CASO CLINÍCOPaciente de 16 años de edad acude a consulta de medicina preventiva refiriendo presentar disminución de agudeza visual, antecedentes de miopía y astigmatismo con debida corrección de error refracta-rio. Actualmente presenta disminución de agudeza visual más notoria en zona central, usando así su visión periférica. Agudeza visual: 20/100. Campimetría: hay es-cotomas. Angiofluorgrafía: muestra una coroides oscura por depósitos de lipofuscina del epitelio pigmentario de la retina dando como resultado la enfermedad de Stargardt.


The Stargardt Macular degeneration is con-sidered a rare disease; one case per 10,000 people is presented. (1)It is Inheritance and it is given an autoso-mal recessive pattern. It is caused by a mu-tation of ABCA4 gene, which has a trans-port function through the membrane of the photoreceptor cells. There are 558 different mutations that can cause it. (2)The Stargardt disease and fundusflavima-culatus are the same disease, the second is a more advanced state of lipofuscin sto-rage. (3)CASE REPORTA 16 years old patient attends to the pre-ventive health referring to have a decrea-sed visual acuity, history of myopia and as-tigmatism with refractive error correction. Currently has more noticeable decrease in central visual acuity, so using your periphe-ral vision. Visual acuity 20/100 Campimetry: there is noscotoma, angiofluorgrafia: it dis-plays a dark choroid by deposits of lipofus-cin of the pigment epithelium of the retina which results the Stargardt disease.

RESUMO

Objetivos: Describir las imágenes de la coroides por tomografía de coherencia óptica (TCO) de dominio espectral en sujetos sanos y con enfermedades coriorretinales. Materiales y métodos: Estudio de serie de casos. Se evaluaron 67 casos que incluyeron sujetos sanos oculares y pacientes con enfermedades coriorretinales. Las tomografías realizadas incluyeron un barrido de la retina y coroides a nivel de la mácula de manera convencional y otro usando el protocolo de profundidad de imagen mejorada (PIM). El espesor coroideo se midió desde el borde exterior del epitelio pigmentario de la retina hasta el reborde escleral interno. Resultados: De los 67 casos, 12 (17.4%) fueron sujetos sanos oculares, 10 (14,5%) con coriorretinopatía serosa central (CSC), 23 (33,4%) degeneración macular relacionada con la edad (DMRE), 9 (13,0%) miopía magna. 13 (18.8%) vasculopatía polipoidal coroidea. Existen diferencias en la calidad de las imágenes con TCO convencional y las realizadas con PIM, permitiendo describir solo coriocapilaris en algunos casos mientras que con el protocolo PIM se puede apreciar el grosor total coroideo. La coroides es de mayor espesor en la vasculopatía polipoidal coroidea (353,92 ± 68,66 µm) y en la CSC (408,81 ± 95,56 µm) que en los sujetos sanos (251,97 ± 66.37 µm) (p<0,05) y está disminuida en DMRE forma seca (124.69 ± 34.02 µm) (p<0,05), al igual que en la miopía magna (118.47 ± 34.02 µm) (p<0,05). Conclusiones: Las imágenes de TCO de la coroides por PIM es una técnica reproducible que permite describir y medir su espesor, estando disminuida en la DMRE, y miopía magna; e incrementada en vasculopatía polipoidal y la CSC.


Objectives: Describe the images of the choroid by optical coherence tomography (OCT) spectral domain in healthy subjects and chorioretinal diseases. Materials and methods: Case series study. We evaluated 67 cases involving healthy ocular subjects and patients with chorioretinal diseases. The scans included a sweep of the retina and choroid at level of the macula conventionally, and other using enhanced depth imaging (EDI). The choroid thickness was measured from the outer edge of the retinal pigment epithelium to the internal scleral rim. Results: Of the 67 cases, 12 (17.4%) were healthy ocular subjects, 10 (14.5%) with central serous chorioretinopathy (CSC), 23 (33.4%) agerelated macular degeneration (AMD), 9 (13.0%) with myopia, 13 (18.8%) with polypoidal choroidal vasculopathy. There are differences in the quality of images with conventional OCT and those with EDI, allowing only to describe the choriocapillaris in some cases while the EDI protocol can appreciate the total thickness of the choroid. The choroid is thicker in polypoidal choroidal vasculopathy (353.92 ± 68.66 microns) and CSC (408.81 ± 95.56 microns) than in healthy subjects (251.97 ± 66.37 mm) (p<0.05) and is decreased in the dry AMD (124.69 ± 34.02 microns) (p<0.05), as well as in the myopia (118.47 ± 34.02 microns) (p<0.05). Conclusions: OCT images of the choroid by PIM is a reproducible technique for describing and measuring its thickness, being decreased in AMD and myopia, and was increased in the polypoidal vasculopathy and CSC.

RESUMO

CLINICAL CASE: No intraocular biopsy technique is free of risk and all have the possibility of giving false negatives due to the difficulty in obtaining a sufficient sample. A modified chorioretinal biopsy was performed on a patient with suspected choroidal melanoma after negative biopsy with 25G vitrectomy. In addition to removing a solid fragment of tumor material using bimanual surgery, material from the lesion was obtained with the vitreotome to perform cytology, which confirmed the diagnosis of melanoma. DISCUSSION: Cytology obtained through the vitreotome in association with removing a solid sample of the choroidal lesion may improve the efficiency of intraocular biopsy.

RESUMO

CASE REPORT: A 56 year old woman with atrial myxoma presented with a visual acuity of no light perception after acute ophthalmic artery obstruction (OAO) associated with stroke. She developed late retinal pigmentary changes due choroidal infarction, typical of the OAO. DISCUSSION: Simultaneous obstruction of the retinal and choroidal circulation was observed in the OAO. Atrial myxoma should be suspected in patients who suffer from OAO associated with stroke. Systemic studies should be performed to find the origin of OAO.

RESUMO

La metástasis intraoculares de tumores sólidos o hematológicos, son un problema clínico para el oftalmólogo práctico y el oncólogo. La localización más frecuente es la coroides, constituyendo el tumor intraocular más frecuente. Suelen diagnósticarsé en pacientes en estadios tumorales muy avanzados, por lo que en el pasado la mayoría de las series publicadas eran descripciones de necropsias. Su diagnóstico generalmente puede hacerse mediante cuidadoso examen. Se estima que la frecuencia general en pacientes que fallecen por cáncer es de aproximadamente 12%, pero puede elevarse en 37% en aquellos con carcinoma mamario, muy superior a la de los tumores primarios, fundamentalmente los melanomas. No obstante, sin compresión ha aumentado en años recientes ofreciendose nuevas formas de tratamiento siendo todavía la radioterapia la que permite a los pacientes mantener una visión.


Intraocular metastases of solid and hematological tumors are clinical problem for the practicing ophthalmologist and oncologist. Its diagnosis can usually be made through careful examination. The most common intraocular tumor. They are often diagnosed in patients in very advanced tumor stages, which is why in the past most of the published series were descriptions of necropsies. The overall frequency of ocular metastases in patients dying of cancer is approximately 12%, but it can be as high as 37% in patients with breast cancer, highly superior to primary tumors, mainly melanomas. Hawever, our understanding of them has increased in recent years, offering new forms of treatment. Radiation therapy is still the cornerstone of treatment, allowing nost patients to maintain usefull vision. Clinical cases with photographic support of an iconic patient are presented to illustrate the problem.
