“…No entanto, diferentemente da DMACB, essa condição apresenta o característico silêncio coroidiano, além das lesões amareladas ("fl ecks") ao nível do EPR. 7,8,9 O exame de autofl uorescência permite analisar a fi siologia do EPR por meio do mapeamento topográfi co do acúmulo de lipofuscina. No caso da DMACB, tal mapa pode evidenciar um área de baixa atividade celular, traduzida por hipoautofl uorescência central com discreto halo hiperfl uorescente4.…”

Benign concentric annular macular dystrophy (BCAMD) is an uncommon disease of which the main feature is the symmetrical and bilateral bull's eye maculopathy. Despite its usual progression with good visual acuity (VA), there might be some variation on its clinical presentation. The following case report is about a 51 year-old female patient who reported progressive and bilateral loss in her VA. Ophthalmological exam revealed bull's eye maculopathy without history of using topical or systemic medications and also no family history. It is important to emphasize the importance of complementary exams, such as fluorescein angiography, optical coherence tomography and autofluorescence, which may help the diagnosis of BMACD. In cases of bull's eye maculopathy, the differential diagnosis plays an essential role, as cone dystrophy, chloroquine intoxication, chronic macular hole and Stargardt's disease must be ruled out.

“…A new in vivo microscopy technique, the Optical Coherence Tomography (OCT), has been developed and allows evaluation of the retina's constitution and its structural integrity (Narfstrom & Petersen-Jones 2013), contributing to diagnosis and monitoring of several retinal diseases (Guedes & Yamane 2003, Gouveia et al 2006, Song et al 2010).…”

Retina assessment by optical coherence tomography of diabetic dogs

et al. 2018

Diabetes mellitus is one of the most common endocrine disorders characterized by relative or absolute lack of insulin; this can lead to several ocular manifestations, among them diabetic retinopathy and cataracts. Diabetic retinopathy (DR) is a microangiopathy that involves retinal precapillary arterioles, postcapillary venules, and large vessels, causing them to be functionally and anatomically incompetent. Hyperglycemia seems to be the most probable cause of damage to the retina due to interference in cellular metabolism and transduction processes. The aim of this study was to evaluate retinal thickness in eight diabetic dogs, four females and four males of different breeds and ages ranging from 6 to 15 years, by optical coherence tomography (OCT) and to compare them with non-diabetic dogs. Assessment provided by OCT in diabetic dogs showed retinal layers thinning and loss of stratification when compared to non-diabetic dogs (198μm versus 219μm respectively), with statistical significance (p=0.008). OCT images may suggest that diabetes mellitus causes retinal neuropathy in dogs, as also seen in diabetic humans.

“…Thus, the OCT was effective in the diagnosis of retinopathy. A OCT permite estudar a retina em perfil, com resolução microscópica, enriquecendo o estudo de várias doenças retinianas, auxiliando no diagnóstico e na monitoração de vá-rias afecções oculares, principalmente das maculopatias no homem, tais como: edema macular presente no edema cistoide de mácula, na retinopatia diabética, no buraco macular e na degeneração macular relacionada à idade (DMRI) (Guedes & Yamane 2003, Gouveia et al 2006, Bordon et al 2008, Song et al 2010.…”

Aspectos da tomografia de coerência óptica em cães com retinopatia

A tomografia de coerência óptica (OCT) é um exame não invasivo e de não contato que permite avaliar a retina e o nervo óptico. As imagens da OCT fornecem informações da constituição da retina e sua integridade estrutural in vivo, gerando imagens de alta resolução, que se assemelham à microscopia óptica. Objetivou-se descrever a técnica de tomografia de coerência óptica (OCT) e sua utilização em cães. Foi possível diferenciar claramente as camadas retinianas de cães hígidos e compará-las com as de cães portadores de atrofia progressiva de retina, que apresentaram perda da estratificação e diminuição significativa das camadas. No descolamento de retina (DR) foi possível observar a separação entre a retina neurossensorial e o epitélio pigmentário da retina (EPR), além da presença de exsudatos intrarretinianos. Assim, a OCT mostrou-se eficaz no diagnóstico de retinopatias.
