Developing a computer program of laser aplication imaged with fundus fluorescein angiography test for retinal diseases

Abstract

Purpose: The aim was to design a model which facilitates laser treatment for Diabetic Retinopathy and the treatment technique was conducted during education of assistant doctors. Materials and Methods: 127 patients diagnosed with diabetic retinopathy had their eyes scanned by Fundus Floresein Angiography before treatment. Kowa VX-10 device was used for scanning / these images. This study had two steps one of which was to detect optic disc and macula region and the other was to design a model which was compatible with laser treatment over image/ display. Matlab software was used. Results: Optic disc and macula regions in 80% of the 127 FFA images with diabetic retinopathy were correctly detected (Standart Deviation: 240 micron). A model which enables laser shot region to be marked and tasks to be stored was designed. Conclusions: During laser treatment, the regions which need protection, are automatically detected and guarded. with this model it provides coordination of information by enabling places which required laser shot to be marked, and is used to develop less risky and more effective treatments. © 2015 Gazi Eye Foundation.
