Dilute pilocarpine test for diagnosis of Adie’s tonic pupil [PDF]
We have compared the diagnostic ability of different concentrations of 0.125% and 0.0625% dilute pilocarpine for detecting denervation supersensitivity in unilateral Adie’s tonic pupil.

Tonic pupil after COVID-19 infection. [PDF]
The latest global health threat is the ongoing outbreak of respiratory disease, which was named COVID-19 and multiple ever-evolving neurological complications have since been reported. We present the case of a patient with a bilateral tonic pupil in the postinfectious context of COVID-19.

Adie’s Tonic Pupil in Systemic Sclerosis: A Rare Association [PDF]
We report a rare association of Adie’s tonic pupil in a patient with systemic sclerosis who was otherwise systemically stable. This paper is an effort to unravel whether the tonic pupil and systemic sclerosis are an association by chance (which may be ...

An interesting case of simultaneous bilateral Adie's tonic pupil
A tonic pupil is usually caused due to parasympathetic denervation of the iris sphincter muscles. It's usually seen in females and in 80 % cases it's unilateral, and 4% of these cases progress to bilateral involvement.

Individual differences in eye blink rate predict both transient and tonic pupil responses during reversal learning. [PDF]
The pupil response under constant illumination can be used as a marker of cognitive processes. In the past, pupillary responses have been studied in the context of arousal and decision-making. However, recent work involving Parkinson's patients suggested

Phasic and tonic arousal distinctly shape human decision bias [PDF]
Neuroscientific theories hypothesize that arousal fluctuations influence human perception and behavior in two functionally distinct ways: through variations in baseline state (tonic arousal) and by transient task-evoked bursts (phasic arousal).

Blue enriched light modulates pupil dilation induced by transcutaneous vagus nerve stimulation [PDF]
Transcutaneous vagus nerve stimulation (tVNS) targets the auricular branch of the vagus nerve and can modulate brainstem arousal systems, including the locus coeruleus–noradrenaline (LC-NE) pathway.

Pupil dynamics reveal preparatory processes in the generation of pro-saccades and anti-saccades in open skill sports athletes [PDF]
This study investigated pupil dynamics to establish a physiological index of mental processes associated with executive functioning, enabling objective evaluation of cognitive load during training to improve understanding of cognitive control in sport ...
