Semiautomated digital image analysis of posterior pole vessels in retinopathy of prematurity

Aggressive posterior retinopathy of prematurity: a pilot study of quantitative analysis of vascular features

“…It is known that even larger infants in these settings may be at risk for severe ROP, presumably because of exposure to high levels of supplemental oxygen [24]. Therefore, accurate diagnosis of severe ROP using clinical and computer-based methods described in this study may become increasingly important [25][26][27][28]. (5) We note that one characteristic of AP-ROP is disease location in zone I or posterior zone II, which may be more difficult to analyze using existing computer-based image analysis systems.…”

Image analysis of posterior pole vessels identifies type 1 retinopathy of prematurity

“…Images were analyzed as obtained (with no alteration of orientation or contrast) using Vasculo-matic ala Nicola version 1.1 (IVAN, Department of Ophthamology and Visual Science, University of Wisconsin-Madison, Madison, WI), a semi-automated image analysis software, to measure width. [3][4][5] For comparison of vessel caliber, inter-eye correlations between measures from paired eyes were adjusted by generalized estimating equations. Analysis of variance established similar demographic characteristics and tested differences among the 3 groups in vessel caliber for arterioles, venules, and combined vessel caliber.…”

Methods for digital analysis of human vascular system. Literature review

“…В работе [45] врачами исследовалась связь скорости изменения диаметра сосудов сетчатки с высоким рис-ком тяжелой ретинопатии недоношенных (РН). В [46,47] авторами были представлены методы прослежи-вания и оценивания извитости сосудов для анализа прогрессирования и степени тяжести РН, исследова-лась корреляция степени тяжести РН с шириной со-судов и извилистости.…”
