Computer-assisted measurement of retinal vascular width and tortuosity in retinopathy of prematurity.
OBJECTIVES To validate the accuracy of ROPtool software in measuring retinal vascular width and tortuosity in a large image set compared with expert diagnoses. METHODS Tortuosity and dilation indexes generated by ROPtool were compared with 3 expert consensus grades of normal, pre-plus, or plus disease for 368 quadrants in 92 RetCam (Clarity Medical Systems, Pleasanton, California) fundus imag...
متن کاملComputer-assisted quantification of vascular tortuosity in retinopathy of prematurity (an American Ophthalmological Society thesis).
PURPOSE Plus disease is severely abnormal dilation and tortuosity of posterior retinal blood vessels in infants with retinopathy of prematurity (ROP). It has become the major criterion for laser treatment in ROP, but its assessment is subjective and prone to error. ROPtool is a computer program that traces retinal blood vessels, measures their tortuosity, and determines whether there is suffici...
متن کاملCharacterization of changes in blood vessel width and tortuosity in retinopathy of prematurity using image analysis
Many retinal diseases are characterised by changes to retinal vessels. For example, a common condition associated with retinopathy of prematurity (ROP) is so-called plus disease, characterised by increased vascular dilation and tortuosity. This paper presents a general technique for segmenting out vascular structures in retinal images, and characterising the segmented blood vessels. The segment...
متن کاملComputer-Assisted Digital Image Analysis of Plus Disease in Retinopathy of Prematurity.
The objective of this study is to review the current state and role of computer-assisted analysis in diagnosis of plus disease in retinopathy of prematurity. Diagnosis and documentation of retinopathy of prematurity are increasingly being supplemented by digital imaging. The incorporation of computer-aided techniques has the potential to add valuable information and standardization regarding th...
متن کاملAccuracy of ROPtool vs individual examiners in assessing retinal vascular tortuosity.
OBJECTIVE To prospectively determine if tortuosity assessment by a computer program (ROPtool) that traces retinal blood vessels and measures their tortuosity was more accurate than that of individual pediatric ophthalmologists. METHODS One hundred eighty-five high-quality RetCam images from premature infants were circulated to 3 retinopathy of prematurity (ROP) experts and 3 other pediatric o...
