This paper introduces an screening method for detecting glaucoma using rim width indicator. Due to some special cases, such as myopia eye, only cup-to-disc ratio may not efficient for screening glaucoma. Rim width based on ISNT rule can be a feature for classification.
Rim width in each section of optic nerve will be measured and then we compare them with ISNT rule for glaucoma classification. According to our results, we can show that the proposed method is an efficient feature for screening glaucoma.
