Decrease of the foveal avascular zone area after internal limiting membrane peeling: single case study
... Conclusions: We observed one case that the FAZ area decreased and the parafoveal inner retinal thickness increased after the vitrectomy with ILM peeling. The decrease in the FAZ area sug- gests that a centripetal ...

Automatic quantification of superficial foveal avascular zone in optical coherence tomography angiography implemented with deep learning
... The foveal avascular zone (FAZ), a region of the fovea without blood, consists of a superficial FAZ (sFAZ) at the super- ficial level of the retina and the deep FAZ (dFAZ) at the deep level of the ...
