Clinical Trials [139 Associated Clinical Trials listed on BioPortfolio]

Color and Pupil Function

This study will examine the effects of different colors of light on pupil function and alertness.

A Pilot Dose-Response Biomarker Study of Brexpiprazole Treatment in PTSD

Determine if brexpiprazole treatment will be associated with a dose-dependent reduction in resting pupil diameter as a reflection of locus coeruleus (LC) norepinephrine (NE) neuron target ...

Reliability of Pupil Response to Acute Pain

The purpose of this research study is to test whether researchers can reliably measure the response pupils have when an acute painful stimulus is experienced. Changes in the size of the pu...

Efficacy of the Canabrava/s Pupil Expansion Device in Cataract Surgery With Small Pupils: The First 30 Cases

To evaluate the intraoperative stability, safety and overall efficacy of the Canabrava Ring (AJL - SPAIN) when used to expand pupils with less diameter than 5 mm and pupils with sphincter ...

Effect of Preoperative Pupil Size on Quality of Vision After Wavefront-Guided LASIK

The purpose of this study is to evaluate whether the size of the pupil has an effect on quality of vision in patients undergoing LASIK surgery.

Recent advances in small pupil cataract surgery.

To highlight the existing and emerging cataract surgery trends in patients with insufficient mydriasis. Discuss the latest pharmacological approaches for pre and intraoperative pupil dilatation. Prese...

Effects of photopic and cirtopic illumination on steady state pupil sizes.

The conventional view was that cones are responsible for pupil constriction in photopic lighting conditions. With the discovery of intrinsically photosensitive retinal ganglion cells (ipRGC), it was f...

Dynamic Lateralization of Pupil Dilation Evoked by Locus Coeruleus Activation Results from Sympathetic, Not Parasympathetic, Contributions.

Pupil size is collectively controlled by the sympathetic dilator and parasympathetic sphincter muscles. Locus coeruleus (LC) activation has been shown to evoke pupil dilation, but how the sympathetic ...

Pupil response and attention skills in Down syndrome.

Down syndrome (DS) is characterized by attentional problems. Little is known about the neural correlates of attention problems in DS due to difficulties in evaluation. Pupil dilation, associated with ...

Individual differences in eye blink rate predict both transient and tonic pupil responses during reversal learning.

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...

Medical and Biotech [MESH] Definitions

Agents that dilate the pupil. They may be either sympathomimetics or parasympatholytics. The latter cause cycloplegia or paralysis of accommodation at high doses and may precipitate glaucoma. Mydriatics are used in eye diseases and to facilitate eye examination.

Unequal pupil size, which may represent a benign physiologic variant or a manifestation of disease. Pathologic anisocoria reflects an abnormality in the musculature of the iris (IRIS DISEASES) or in the parasympathetic or sympathetic pathways that innervate the pupil. Physiologic anisocoria refers to an asymmetry of pupil diameter, usually less than 2mm, that is not associated with disease.

Constriction of the pupil in response to light stimulation of the retina. It refers also to any reflex involving the iris, with resultant alteration of the diameter of the pupil. (Cline et al., Dictionary of Visual Science, 4th ed)

The inspection of one's own body, usually for signs of disease (e.g., BREAST SELF-EXAMINATION, testicular self-examination).

Conditions which affect the structure or function of the pupil of the eye, including disorders of innervation to the pupillary constrictor or dilator muscles, and disorders of pupillary reflexes.
