The Effect of Photographic Light Exposure on Cup to Disc Ratio Grading [PDF]

, 2021
Abstract Background: Digital optic disc images are integral in remote telehealthcare, yet no quality control standards exist for the exposure setting of the images. This study evaluated the relationship between exposure setting and cup/disc ratio (c/d) grading among glaucoma specialists.

Cup to disc ratio by optical coherence tomography is abnormal in multiple sclerosis [PDF]

Journal of the Neurological Sciences, 2011
To identify and characterize cup to disc ratio (CDR) and related optic nerve head abnormalities in multiple sclerosis (MS) using spectral domain optical coherence tomography (OCT).While CDR is routinely assessed by ophthalmologists in the evaluation of glaucoma, CDR and related optic nerve head metrics remain largely unexplored in MS.Cirrus-HD (high ...

Glucagon‐Like Peptide‐1 Receptor Agonists in Multiple Sclerosis: A Topical Narrative Review

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT The glucagon‐like peptide‐1 (GLP‐1) receptor agonists (RAs) are a relatively new class of drugs that were initially approved by the US Food and Drug Administration to improve glycemic control in patients with type 2 diabetes mellitus and, subsequently, weight reduction in patients with obesity.

Determinants of the Optic Cup to Disc Ratio in an Asian Population [PDF]

Archives of Ophthalmology, 2008
To describe the distribution and determinants of the optic cup to disc ratio (CDR) in Malay adults in Singapore.This population-based, age-stratified study examined 3280 Malay people aged 40 to 80 years in Singapore. Participants underwent a standardized interview and an ocular examination. A slitlamp examination measured the vertical dimensions of the
