ABSTRACT
ABSTRACT Wide-field angiography enables assessing peripheral areas with better quality and gives greater deep focus, which improves the image periphery. Some studies have proposed the usefulness of these angiographic systems in inflammatory diseases of the retina. However, few studies have evaluated this technique in Eales disease. We present a case series in which 5 eyes of 3 patients with Eales disease were evaluated by using retinal fluorescein angiography with 30º, 50º, and 150º lenses in a laser-scanning ophthalmoscope. These cases highlight the usefulness of wide-field fluorescein angiography in the diagnosis and follow-up of peripheral ischemic retinal areas in Eales disease, which enables better follow-up than possible with conventional fluorescein angiography images.
RESUMO A angiografia de campo amplo permite avaliar áreas periféricas com melhor qualidade e proporciona maior foco profundo, melhorando a imagem da periferia. Alguns estudos têm proposto a utilidade desses sistemas angiográficos nas doenças inflamatórias da retina. No entanto, poucos estudos avaliaram esta técnica na doença de Eales. Apresentamos uma série de casos em que 5 olhos de 3 pacientes com doença de Eales foram avaliados usando angiografia de fluoresceína da retina com lentes de 30º, 50º e 150º em um oftalmoscópio de varredura a laser. Esses casos destacam a utilidade da angiografia com fluoresceína de campo amplo no diagnóstico e no acompanhamento das áreas isquêmicas periféricas da retina na doença de Eales, permitindo um melhor acompanhamento do o possível com imagens por angiofluoresceinografia convencional.

Objetivo: comparar los resultados del tratamiento intravítreo de bevacizumab y de acetato de triamcinolona en el edema macular secundario ante la oclusión de rama venosa retiniana. Métodos: estudio prospectivo, intervencional, aleatorio y comparativo realizado en 34 pacientes. El grupo 1 (16 pacientes) con inyección intravítrea de acetato de triamcinolona y el grupo 2 (18 pacientes) con inyección de bevacizumab hasta completar 3 dosis en cada grupo, seguida la tercera dosis de grid macular. La dosis inicial fue a los 3 meses de la afección, y la evaluación final a los 12 meses. Se evaluó la agudeza visual mejor corregida (Snellen), grosor macular y complicaciones. Resultados: en el grupo 1 la mejor agudeza visual con corrección evolucionó de 0,29 (0,05-0,5) a 0,64 (0,05-1,0); en el grupo 2 de 0,24 (0,05-0,5) a 0,66 (0,11,0). El grosor macular en el grupo 1, de 551,3 (346-967) micras, mejoró a 204,06 (112-449) micras; en el grupo 2, de 546,2 (283-1020) micras, hasta un grosor retinal foveal de 181,05 (112-312) micras. Como complicaciones, en el grupo 1 hubo un incremento de la tensión ocular en el 25,0 por ciento de los pacientes y una progresión de catarata en el 12,5 por ciento. Conclusiones: el tratamiento de inyección intravítrea de bevacizumab en el edema macular secundario a oclusiones venosas de rama retiniana muestra mejor resultado que el de acetato de triamcinolona. También son menores las complicaciones asociadas al bevacizumab(AU)
Objective: to compare the results of the intravitreal treatment with bevacizumab and with triamcinolone acetonide in the macular edema secondary to branch retinal vein occlusion. Methods: a prospective, interventional, random and comparative study was carried out in 34 patients. The first group (16 patients) received intravitreal triamcinolone acetonide injection whereas the second group (18 patients) had bevacizumab injection up to completing three doses in each group, followed by a third dose of macular grid. The initial dose was applied three months after the occurrence of edema and the final evaluation was made 12 months afterwards. Best corrected visual acuity (Snellen's chart), the macular thickness and complications were assessed. Results: in the first group, the best corrected visual acuity increased from 0,29 (0,05-05) to 0,64 (0,05-1,0) whereas in the second group it went from 0,24 (0,05-05) to 0,66 (0,1-1,0).The macular thickness of 551,3 (346-967) microns of the first group improved when reaching 204,06 (112-449) microns and that of the second group went from 546,2 (283-1020) microns to 181,05 (112-312) microns. As to the complications, 25 percent of patients of the first group experienced eye hypertension, and 12,5 percent of patients in the same group had cataract progression. Conclusions: intravitreal bevacizumab injection treatment of the macular edema secondary to branch retinal vein occlusion was better than that based on triamcinolone acetonide injection. The complications associated to bevacizumab treatment were fewer(AU)

Relatamos caso de um paciente de 14 anos, sexo masculino, que foi admitido com queixa de embaçamento visual bilateral há dois anos. Ao exame oftalmológico observou-se leve hiperemia e edema de disco óptico bilateral, exsudação retiniana, poucas hemorragias retinianas, múltiplos aneurismas, assim como sinais de vasculite. A angiofluoresceinografia demonstrou isquemia periférica extensa, dilatações e hiperfluorescência das paredes dos vasos, e vazamento tardio do disco óptico nas fases finais do exame em ambos os olhos. Este caso representa uma rara entidade caracterizada por oclusão retiniana vascular periférica, vasculite retiniana, múltiplos aneurismas retinianos e neurorretinite (IRVAN). Avaliação sistêmica e laboratorial não revelaram nenhuma anormalidade. O paciente foi submetido à panfotocoagulação de retina com laser de argônio em ambos os olhos, e iniciado tratamento com prednisona via oral, com manutenção da acuidade visual de 20/25 depois de um ano de acompanhamento. O tratamento com laser deve ser considerado quando houver qualquer evidência angiográfica de má perfusão retiniana, e antes do desenvolvimento de qualquer sinal de neovascularização de retina.
A case of a 14 year-old boy that was admitted complaining of bilateral ocular visual blurring for 2 years is reported. The ophthalmological examination disclosed bilateral mild optic disc hyperemia and swelling, retinal exudation, few retinal hemorrhages, multiple aneurysms, as well as vasculitis. Fluorescein angiography showed extensive peripheral retinal ischemia, dilatations and hyperfluorescence of the vessels walls, and leakage of the optic disc in the late phases in both eyes. This rare case represents an entity characterized by peripheral retinal vascular occlusion, retinal vasculitis, multiple posterior retinal aneurysms, and neuroretinitis (IRVAN). Systemic evaluation and laboratory work-up did not suggest any systemic abnormality. Panretinal laser photocoagulation was performed in both eyes, and the patient was treated with oral prednisone with maintenance of the visual acuity after 1 year of follow-up. Laser treatment should be considered when angiographic evidence of widespread retinal no perfusion is present, and before the development of signs of retinal neovascularization.

PURPOSE: To report a 16-year long-term follow-up of a patient with acute multifocal hemorrhagic retinal vasculitis (Blumenkranz syndrome). A 21-year old male was seen in 1994 with acute multifocal hemorrhagic retinal vasculitis (Blumenkranz syndrome), first in the left eye, and later in the right eye. He was treated with retinal photocoagulation in areas of retinal ischemia and oral steroids, followed by sequential annual fundus examination and photography for 16 years. Vision improved to 20/25 in both eyes after retinal ischemic areas photocoagulation and oral steroids, and his vision has been maintained for 16 years. Photocoagulation of retinal ischemia and oral steroids are effective for the treatment of acute multifocal hemorrhagic retinal vasculitis (Blumenkranz syndrome).
Relato de caso com acompanhamento por 16 anos de um paciente com a vasculite hemorrágica multifocal aguda (síndrome de Blumenkranz). Um paciente de 21 anos de idade foi diagnosticado em 1994 com a vasculite hemorrágica multifocal aguda (síndrome de Blumenkranz), primeiro no olho esquerdo e depois no olho direito. Foi tratado com fotocoagulação retiniana nas áreas retinianas isquêmicas e corticosteroide oral e seguido por exames complementares da retina por 16 anos. A visão melhorou para 20/25 em ambos os olhos após a fotocoagulação retiniana nas áreas isquêmicas da retina e corticosteroide oral permanecendo assim até o momento por 16 anos. A fotocoagulação retiniana nas áreas isquêmicas e o uso de corticosteróide oral são tratamentos efetivos para a vasculite hemorrágica multifocal aguda (síndrome de Blumenkranz).

In recent years, ocular involvement due to TB has re-emerged. Tuberculous uveitis is a readily treatable disease and the consequences of delay in either ocular or systemic diagnosis can be very serious for the patient. It is important to have a high index of suspicion of the diagnosis in patient with unexplained chronic uveitis and this will be influenced by the socio-economic circumstances, family history, ethnic origin, and previous medical history of the patient. Treatment with antituberculous therapy combined with systemic corticosteroids resolves inflammation without recurrences after medical therapy
