“…Most computerized blood vessel detection work consists of a series of image processing techniques, as the retinal image is generally the main input for analysis in such research work. Authors in [3] proposed a novel technique to extract energy distribution over wavelet subband signatures using 2D wavelet transform and passed these signatures to different feature ranking and feature selection strategies. The energy obtained from detailed coefficient is used to classify normal and glaucomatous image with high accuracy.…”

Evaluating the anterior chamber angle with gonioscopy is an essential part of evaluating patients at risk of contracting glaucoma and neovascularization. It also provides useful information for patients with iris abnormalities or a history of trauma or ocular inflammation. Unfortunately, gonioscopy is underutilized by both optometrists and ophthalmologists. There are many symptoms that call for performing gonioscopy. One of the most common reasons for performing gonioscopy is in cases where the doctor suspects a patient is at risk of being infected with angle closure glaucoma (ACG) with pupil dilation. This paper aims at calculating the angle of open and closed glaucoma as a first step of determining the thickness of the liquid available on the cornea, which has been proven to be very helpful in preventing vision loss. The techniques involved in this study include proposing an eye segmentation process, the calculation of the angle opening distance (AOD), trabecular iris angle (TIA), and trabecular iris space area (TISA). The simulation results obtained and the performance of the proposed method are found to be highly efficient and accurate.

“…Most electronic vein location work comprises of a progression of picture handling procedures, as the retinal picture is by and large the fundamental info for examination in such research work. Creators proposed a novel strategy to concentrate vitality appropriation over wavelet sub-band marks utilizing 2D wavelet change and passed these marks to diverse element positioning and highlight choice methodologies [4]. The vitality acquired from point by point coefficient is utilized to group ordinary and glaucomatous picture with high exactness.…”
