Relative afferent pupillary defect (RAPD) is a condition in which pupils respond differently to light stimuli shone in one eye at a time. This response is due to unilateral or asymmetrical disease of the retina or optic nerve (only optic nerve disease occurs in front of the lateral geniculate body).

A relative afferent pupillary defect (RAPD), also known as a Marcus Gunn pupil (after Robert Marcus Gunn), is a medical sign observed during the swinging-flashlight test [1] whereupon the patient's pupils excessively dilate when a bright light is …

The ‘swinging light test’ is used to detect a relative afferent pupil defect (RAPD): a means of detecting differences between the two eyes in how they respond to a light shone in one eye at a time.

A relative afferent pupillary defect (RAPD) also known as a Marcus Gunn pupil, is a critically important ophthalmological examination finding that defines a defect ( pathology) in the pupil pathway on the afferent side.

2017年11月9日 · RAPD is an inexpensive yet powerful typing method for many bacterial species. Silver-stained polyacrylamide gel showing three distinct RAPD profiles generated by primer OPE15 for Haemophilus ducreyi isolates from Tanzania, …

2022年8月15日 · Marcus Gunn pupil is a rare condition in which a person’s pupil does not respond to light correctly in one eye. It is also called Marcus Gunn syndrome or relative afferent pupillary defect (RAPD). In healthy eyes, pupils constrict (get smaller) in bright conditions and dilate (get bigger) in dark conditions.

Random amplified polymorphic DNA (RAPD), pronounced "rapid", [1] is a type of polymerase chain reaction (PCR), but the segments of DNA that are amplified are random. [2]

2008年9月15日 · A relative afferent pupillary defect (RAPD) can be a worrisome exam finding, so an understanding of its possible etiologies is crucial. Most often, patients have an ocular or medical history that might explain its presence.

2016年1月1日 · A relative afferent pupillary defect (RAPD) is a clinical sign used to detect a lesion/defect in the pupil pathway on the afferent side. The direct response of the pupil to light can be compared to the contralateral consensual response …

Relative afferent pupillary defect (RAPD), also known as Marcus Gunn pupil, is a condition wherein the pupils react minimally to bright light. RAPD was named after Scottish ophthalmologist Robert Marcus Gunn.
