Abstract
Glaucoma is an eye disease which may slowly lead to loss of vision. Hence early
detection of this disease may help in proper treatment and prevention of vision loss. Retinal
Nerve Fiber Layer (RNFL) thining in one of the important indicators of Glaucoma. In this
work, a simple RNFL thickness measurement technique from OCT images using color space
conversion and morphological processing has been proposed. Seven features like vertical
Cup to Disc Ratio (CDR), Horizontal CDR, Average RNFL thickness and average thickness
of the four quadrants of RNFL has been used for the detection of Glaucoma. The method
has been tested using Back Propagation Artificial Neural Network (ANN), by taking
different combination of these features and it has been found that the higher accuracy is
achieved when the thicknesses of the RNFL quadrants are considered.
