Image characteristic and diagnostic value of OCTA in patients with age related macular degeneration / 国际眼科杂志(Guoji Yanke Zazhi)

@#Optical coherence tomography angiography(OCTA)is a rapid and non-invasive imaging tool, which can provide real-time flow imaging of retina and choroid. Compared with traditional angiography, OCTA can produce more detailed and high-resolution vascular images without increasing the risk due to contrast medium. Age-related macular degeneration(ARMD)is one of the major senile blinding eye diseases in the world, OCTA can well display the image of choroidal neovascularization and provide the possibility for early diagnosis and intervention. This review summarizes the OCTA image characteristics and clinical diagnostic value in patients with ARMD.

Posterior polar annular and hemispheric choroidal and retinal dystrophy: Optical coherence tomographic angiography description of a rare case

Posterior polar annual choroidal dystrophy is a rare disease which affects the retina and choroid in an annular pattern. Our patient was referred to us a case of atypical retinitis pigmentosa. Fundus examination showed a normal optic disc, normal arterioles, and no bone spicules. The right eye showed a hemispheric pattern and the left eye showed an annular pattern of retinal and choroidal dystrophy. We describe the retinal and choroidal angiographic features of this case by optical coherence angiography.
