PURPOSE. To describe and evaluate the performance of a computerized automated segmentation technique for use in quantification of the foveal avascular zone (FAZ). METHODS. A computerized technique for automated segmentation of the FAZ using images from fundus fluorescein angiography (FFA) was applied to 26 transit-phase images obtained from patients with various grades of diabetic retinopathy. The area containing the FAZ zone was first extracted from the original image and smoothed by a…

Segmentation of Foveal Avascular Zone of the Retina Based on Morphological Alternating Sequential Filtering

This work proposed an automatic segmentation of FAZ using high-resolution retinal images captured by a retinography conjugated to Retinal Function Imager (RFI) apparatus, and the pixels corresponding to FAZ are automatically detected, segmented and measured.

Fully automatic segmentation of fluorescein leakage in subjects with diabetic macular edema.

A fully automated algorithm can reproducibly and accurately quantify the area of leakage of clinical-grade FA video and is congruent with expert manual segmentation.

A new technique for estimating the foveal avascular zone dimensions

A new methodology for segmenting and quantifying the Foveal Avascular Zone (FAZ) with considerable improvement in accuracy when compared to system segmentation and the ground truth is provided.

Foveal Avascular Zone Segmentation in Clinical Routine Fluorescein Angiographies Using Multitask Learning

This approach exploits an additional Euclidean distance map prediction task to better deal with variable imaging conditions, by benefiting from its regularization effect and is the first deep learning method for FAZ segmentation in FA ever published.

Comparison of foveal avascular zone in diabetic retinopathy, high myopia, and normal fundus images

The study results show that the FAZ area in Diabetic Retinopathy is significantly different when compared to myopic eyes (p=0.003) and normals.

Automated measurement of the foveal avascular zone in healthy eyes on Heidelberg Spectralis Optical Coherence Tomography Angiography

Automated determination of the FAZ area in HS-OCTA is feasible and less human-dependent by mKSM even if the image is not perfectly centred or has artefacts, and the scatterplots show a strong correlation between human and automatic measurements.

A new combined method based on curvelet transform and morphological operators for automatic detection of foveal avascular zone

A new fully automatic system is presented to find the location of FAZ in fundus fluorescein angiogram photographs based on digital curvelet transform (DCUT) and morphological operations.

Relationship between the foveal avascular zone and foveal pit morphology.

More work is needed to confirm the developmental link between the size of the FAZ and the degree of foveal pit excavation, and to understand the relationship between these and other anatomic features of the humanfoveal region, including peak cone density, rod-free zone diameter, and Henle fiber layer.



Bayesian detection of the fovea in eye fundus angiographies

The proposed methodology is based on Bayesian statistical methods that allow to incorporate the previous knowledge about the eye fundus in the model, and is applied to di€erent cases of diabetic retinopathy and vein occlusions.

Quantification of diabetic macular edema.

By performing vitreous fluorophotometry and fluorescein angiography, it is possible to quantitate two major components of diabetic maculopathy: breakdown of the blood-retinal barrier and macular ischemia, both of which are highly correlated with visual acuity.

Diabetic retinopathy: I. The measurement of intercapillary area in normal retinal angiograms.

[The foveal avascular zone in nonproliferative diabetic retinopathy].

The results obtained have shown that the area of the foveolar avascular zone in diabetics with nonproliferative retinopathy is significantly larger than in healthy eyes due to the destruction of the parafoveal capillary net, although the areas of the FAZ inhealthy eyes could considerably vary.

Multifocal electroretinogram (mfERG) in patients with diabetes mellitus and an enlarged foveal avascular zone (FAZ)

A correlation between the ischemic areas and prolonged implicit time in the mfERG indicates that alterations in neuronal macular function due to ischemia might precede the deterioration of visual acuity.

Foveal avascular zone in macular branch retinal vein occlusion

MBRVO causes an irregular enlargement of the foveal avascular zone which seems to represent the most important feature related to visual acuity impairment, which is found in patients affected by macular branch retinal vein occlusion.

Quantification of macular ischaemia in sickle cell retinopathy.

Macular ischaemia has a central role in the pathophysiology and prognosis of retinal macular disease. We attempted to quantitate two of its major components as follows: vascular nonperfusion, by

Contrast sensitivity loss is coupled with capillary dropout in patients with diabetes.

The alterations of the perifoveal network are related to selective disturbances of central visual function as measured by contrast sensitivity in patients with diabetes, and measurement of contrast sensitivity may provide a clinical adjunct in further identifying early ischemic diabetic maculopathy.
