Digital contrast sensitivity chart with varying visual acuity: Development and validation
Oman Journal of Ophthalmology, 2023 BACKGROUND: Contrast sensitivity (CS) evaluation is very much necessary for the diagnosis and management of eye conditions. Several disadvantages seen in the traditionally used Pelli-Robson (PR) chart persuaded us to develop a novel digital device for ...

Octopaminergic modulation of contrast sensitivity
Frontiers in Integrative Neuroscience, 2012 Sensory systems adapt to prolonged stimulation by decreasing their response to prevailing stimulus conditions. Whereas visual motion adaptation has traditionally been studied in immobilized animals, recent work indicates that the animal’s behavioral ...
