This study will examine the effects of different colors of light on pupil function and alertness.
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 ...
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...
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 ...
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.
Tadpole pupil is a rarely encountered phenomenon caused by episodic, segmental iris dilator muscle spasm of short duration (2-15 minutes), occurring in clusters without a known precipitating factor. I...
In cases of pupillary capture after previous transscleral fixation of an intraocular lens (IOL), an across-pupil suture technique is sometimes used to stabilize the IOL. We investigated the optical ef...
We determine the effect of short-term light adaptation on the pupil light reflex and the melanopsin mediated post-illumination pupil response (PIPR). Inner and outer retinal photoreceptor contribution...
MAIA microperimetry assesses macular sensitivity to projected point light sources and maps eye movements to assess fixation stability. While microperimetry is gaining prominence as an assessment tool ...
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...
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.
