Segmentation of Choroidal Neovascularization in Fundus Fluorescein Angiograms

Abstract: Choroidal neovascularization (CNV) is a common manifestation of age-related macular degeneration (AMD). It is characterized by the growth of abnormal blood vessels in the choroidal layer causing blurring and deterioration of the vision. In late stages, these abnormal vessels can rupture the retinal layers causing complete loss of vision at the affected regions. Determining the CNV size and type in fluorescein angiograms is required for proper treatment and prognosis of the disease. Computer-aided methods for C… Show more

“…Classical lesion detection were segmentation methods based on mathematical morphology, region growing, or pixel classification, using fundus images 18 20 . Walid presented a framework for segmenting Choroidal neovascularization lesions based on parametric modeling of the intensity variation in FFA 21 . However, limited expert labeled data is a common problem encountered.…”

“…In the proposed work, the Frangi filter is employed for the enhancement of the vascular network in the retinal image. [22][23][24][25][26][27][28] The Hessian eigenvalues-based approach is used in the Frangi filter for the contrast enhancement of foreground pixels that is, blood vessels. As a result, nonvessel pixels of the major and minor vessels are eliminated.…”

“…Choroidal neovascularization (CNV), also known as subretinal neovascularization, is a basic pathological change of various intraocular diseases such as age-related macular degeneration, central exudative chorioretinopathy, idiopathic choroidal neovascularization, pathological myopic macular degeneration, and ocular histoplasmosis syndrome (DeWan et al, 2006;Abdelmoula et al, 2013;Jia et al, 2014;Liu et al, 2015;Zhu et al, 2017). It often involves the macula, causing serious damage to the central vision.…”
