Isolated relative afferent pupillary defect secondary to contralateral midbrain compression.
BACKGROUND Relative afferent pupillary defects are typically related to ipsilateral lesions within the anterior visual pathways. OBJECTIVE To describe a patient who had a workup for headache and was found to have an isolated left relative afferent pupillary defect without any other neurological findings. DESIGN We review the neuroanatomy of the pupillary light reflex pathway and emphasize t...
متن کاملHow to test for a relative afferent pupillary defect (RAPD)
Light source 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. The test can be very useful for detecting unilateral or asymmetrical disease of the retina or optic nerve (but only optic nerve disease that occurs in front of the optic chiasm). The phy...
متن کاملAfferent pupillary defect in pineal region tumour.
A patient is described in whom an afferent pupillary defect was an early sign of a tumour in the pineal region. It is suggested that this was due to involvement of the pupillary afferent fibres between the optic tract and pretectal nucleus contralateral to the affected pupil.
متن کاملOrigin of the relative afferent pupillary defect in optic tract lesions.
OBJECTIVE To determine the percent decussation of pupil input fibers in humans and to explain the size and range of the log unit relative afferent pupillary defect (RAPD) in patients with optic tract lesions. DESIGN Experimental study. PARTICIPANTS AND CONTROLS Five patients with a unilateral optic tract lesion. METHODS The pupil response from light stimulation of the nasal hemifield, tem...
متن کاملCross-sectional pupillographic evaluation of relative afferent pupillary defect in age-related macular degeneration
To evaluate, using pupillography, the difference between eyes affected by age-related macular degeneration and their contralateral normal eyes with regard to the mean relative afferent pupillary defect (RAPD) score. Also, to ascertain any correlations between this difference in RAPD score and differences in visual acuity or age-related macular degeneration (AMD) dimensions. Measurements were ma...
