Purpose: To design software with a novel algorithm, which analyzes the tortuosity and vascular dilatation infundal images of retinopathy of prematurity (ROP) patients with an acceptable accuracy for detecting plus disease.
Methods: Eighty-seven well-focused fundal images taken with RetCam were classified to three groups of plus,non-plus, and pre-plus by agreement between three ROP experts. Automated algorithms in this study weredesigned based on two methods: the curvature measure and distance transform for assessment of tortuosityand vascular dilatation, respectively as two major parameters of plus disease detection.
Results: Thirty-eight plus, 12 pre-plus, and 37 non-plus images, which were classified by three experts, weretested by an automated algorithm and software evaluated the correct grouping of images in comparison toexpert voting with three different classifiers, k-nearest neighbor, support vector machine and multilayer perceptronnetwork. The plus, pre-plus, and non-plus images were analyzed with 72.3%, 83.7%, and 84.4%accuracy, respectively.
Conclusions: The new automated algorithm used in this pilot scheme for diagnosis and screening of patientswith plus ROP has acceptable accuracy. With more improvements, it may become particularly useful, especiallyin centers without a skilled person in the ROP field.
