Rim-to-Disc Ratio Outperforms Cup-to-Disc Ratio for Glaucoma Prescreening. [PDF]
Sci Rep, 2019 AbstractWe present a novel and fully automated fundus image processing technique for glaucoma prescreening based on the rim-to-disc ratio (RDR). The technique accurately segments the optic disc and optic cup and then computes the RDR based on which it is possible to differentiate a normal fundus from a glaucomatous one. The technique performs a further

Optic Disc and Optic Cup Segmentation Methodologies for Glaucoma Image Detection: A Survey
Journal of Ophthalmology, 2015 Glaucoma is the second leading cause of loss of vision in the world. Examining the head of optic nerve (cup-to-disc ratio) is very important for diagnosing glaucoma and for patient monitoring after diagnosis.

The impact of anthropometric and ocular parameters on optic cup-to-disc ratio. [PDF]
BMJ Open Ophthalmol, 2017 To assess a relationship between vertical cup--to--disc ratio (VCDR), which is a useful tool to assist in the diagnosis of glaucoma in the early to medium--advanced stages, and intraocular pressure (IOP), central corneal thickness (CCT), body mass index (BMI) and body fat percentage (BFP).The data were collected from general populations living in the ...
