Automated cup-to-disc ratio quantification via color fundus photography for chronic glaucoma screening. [PDF]
BMC Med ImagingPurpose Glaucoma is a leading cause of irreversible blindness, and accurate cup-to-disc ratio (CDR) measurement is essential for early detection. This study presents an enhanced deep learning–based system for automated CDR estimation and glaucoma ...

Similarity regularized sparse group lasso for cup to disc ratio computation. [PDF]
Biomed Opt Express, 2017 Automatic cup to disc ratio (CDR) computation from color fundus images has shown to be promising for glaucoma detection. Over the past decade, many algorithms have been proposed. In this paper, we first review the recent work in the area and then present a novel similarity-regularized sparse group lasso method for automated CDR estimation. The proposed

Comparison of vertical cup-to-disc ratio estimates using stereoscopic and monoscopic cameras. [PDF]
Eye (Lond), 2021 Background: The use of monoscopic cameras for glaucoma screening is increasing due to their portability, lower cost, and non-mydriatic capabilities. However, it is important to compare the accuracy of such devices with stereoscopic cameras that are used clinically and are considered the gold standard in optic disc assessment.

Retinal nerve fiber layer defects in the presence of a physiological cup to disc ratio — a case series [PDF]
, 2021 Retinal nerve fiber layer (RNFL) defects are one of the earliest signs of glaucoma. Typically, these RNFL defects are associated with an increased cup/disc ratio and a thinning of the neuroretinal rim. When the cup/disc ratio is within normal limits, the

Highly Accurate and Precise Automated Cup-to-Disc Ratio Quantification for Glaucoma Screening. [PDF]
Ophthalmol SciABSTRACT Objective An enlarged cup-to-disc ratio (CDR) is a hallmark of glaucomatous optic neuropathy. Manual assessment of CDR may be inaccurate and time-consuming. Herein we sought to develop and validate a deep-learning-based algorithm to automatically determine CDR from fundus images.

Cup-to-disc and arteriole-to-venule ratios in preterm birth [PDF]
Eye, 2015 To investigate the influence of preterm birth on the optic disc and retinal vessels by measurements of cup-to-disc (C/D) ratio and arteriole-to-venule (A/V) ratio.Eighty-three eyes of 42 preterm births were included. In the age- and sex-matched control group, 83 eyes of 42 full-term births were used. Fundus color photographs were taken. ImageJ software
