Pupillary constriction to darkness.
Patients with congenital achromatopsia and congenital stationary night blindness have been known to show a transient pupillary constriction to darkness. We examined 50 normal subjects and 108 patients with retinal and optic nerve dysfunction to see if any had an initial pupillary constriction to darkness. We used a new infrared television apparatus. Four patients with congenital stationary nigh...
متن کاملInduced Pupillary Oscillations.
THE ease with which the iris can be observed, combined with the long course of the nervous pathways, accounts, in great measure, for the extensive literature on pupillary reflexes. 1Much of this work has been undertaken by clinicians seeking guidance in diagnosis. Yet, in most present-day investigations, use is made of complex apparatus which is far from suitable for use in routine clinical exa...
متن کاملPupillary responses in amblyopia.
Relative afferent pupillary defects (RAPD) were detected in 32.3% of patients with amblyopia by a modification of the swinging flashlight test and the synoptophore. After consideration of various clinical investigations the significant factors identified in patients showing a RAPD were: anisometropia, early age of onset where strabismus was present, level of visual acuity following treatment, l...
متن کاملCongenital fibrovascular pupillary membrane
Congenital fibrovascular pupillary membrane (1-4) is an unilateral ocular change of the anterior segment (Figure 1). This abnormality was first reported by Cibis et al. in 1986. In some cases, progressive miosis, posterior embryotoxon and abnormality of the anterior chamber angle have been documented. Pupillary membrane might not be adhered to crystalline, or it can also be associated with ante...
متن کاملSonographic Consensual Pupillary Reflex
Patients suffering from severe orbital trauma are at risk for numerous complications, including orbital compartment syndromes. This can result in an afferent pupillary defect, which must be evaluated for on physical examination. Unfortunately, these at-risk patients are often challenging to examine properly due to surrounding edema. Point-of-care ultrasonography can be used as an adjunct to the...
