Automatic Segmentation of the Outer and Inner Foveal Avascular Zone by Convolutional Filters

International Journal of Imaging Systems and Technology
ABSTRACT In this paper a new algorithm for segmentation of the foveal avascular zone in optical coherence tomography angiography images of the superficial capillary plexus is presented and evaluated. The algorithm is based on convolutional techniques, and for evaluation it has been compared with a collection of manual segmentations ...

[The foveal avascular zone in nonproliferative diabetic retinopathy].

Vojnosanitetski pregled, 1991
The areas of the foveolar avascular zone (FAZ) were measured in the fluorescein angiograms and the comparison was made between 44 eyes of 22 diabetics with nonproliferative diabetic retinopathy and 32 eyes of the healthy nondiabetic controls. It was found that the area of the FAZ in diabetics ranged between a mean of 0.26 +/- 0.07 mm2 and in healthy ...

Retinal fixation point location in the foveal avascular zone.

Investigative ophthalmology & visual science, 1990
The site of normal fixation is often assumed to be centered in the foveal avascular zone (FAZ). This assumed anatomic relationship is used during photocoagulation therapy as an objective guide to avoid damaging critical retinal structures on or near fixation.
