A Novel Approach for Glaucoma Detection Using Cup Disk and Rim Disk Ratio

Arvind Kundu, G. Priyanka, K. Priyanka


Glaucoma is a continual ailment which if no longer detected in early phases can lead to permanent blindness. The clinical techniques used by ophthalmologists like HRT and OCT is highly-priced and time-consuming. As a result, there is a have got to advance automatic pc aided process which is able to observe the stage of glaucoma efficiently and in much less time.

Optic disk Ratio and optic cup Ratio are high facets which help in diagnosing glaucoma. As a consequence suitable segmentation of optic disk and optic cup plays a predominant role in detecting the disease. In this paper, an adaptive threshold cantered approach which is unbiased of snapshot fine and invariant to noise is used to section optic disk, optic cup, Neuroretinal rim and cup to disk ratio is calculated to monitor glaucoma. An additional ocular parameter, rim to disk ratio is regarded which in mixture with CDR gives extra reliability in deciding on glaucoma. Furthermore, to that Morphological Operations are utilizing to the method the whole photo to makes the procedure extra amazing. In the end, an SVM classifier has been used to categorize the graphics as glaucomatous or not glaucomatous.

 The experimental outcome bought are in comparison with those of ophthalmologist and are located to have extra efficient and high accuracy of 90%. Also, in addition, the proposed system is faster having low computational cost.

As compared to different tricky instruments, digital fondues camera is more cost effective and is more commonly used in general eye examination.
