Description
Technical Field
The invention relates to medical equipment, in particular to a pupil size measuring pen.
Background
The regulation of the pupil size is regulated by parasympathetic fibers of the oculomotor nerve and sympathetic fibers from sympathetic ganglia on the neck, which innervate the pupillary sphincter muscle and constrict the pupil; sympathetic fibers govern mydriasis and dilate the pupil; under normal light, the normal diameter of the pupil is 3-4 mm, the pupil is contracted when the diameter is smaller than 2mm, and the pupil is dilated when the diameter is larger than 5 mm.
The change of pupil size and shape and reaction can reflect systemic diseases besides the diseases of ophthalmology (such as iritis and the like), and is especially valuable in diagnosis, identification, nursing treatment and the like of neurology, brain surgery and internal medicine diseases, for example, the miosis can be unilateral or bilateral miosis, ① unilateral miosis is shown in Homer symptoms caused by stimulation on one side oculomotor nerve or damage of cervical sympathetic nerve fibers, the pupil can also be reduced by corneal or intraocular foreign matters, ② bilateral miosis is mostly seen in the elderly, presbyopia, alcoholism, drug intoxication (such as morphine, opium, barbiturates and the like), sleep, coma, infant, deep inspiration, syphilis, cerebral hypertension, diabetes and the like also have miosis, bilateral miosis is mostly seen in brain stem diseases, or is wide cerebral pathological changes, fourth ventricle pathological changes and reaches the cerebral bridge, cerebral hemorrhage can appear in bilateral pinpoint seizures, the disease is also accompanied by deep coma, attack attacks of encephalomydriasis, cerebral apoplexy, central line changes, or the pupillary contraction is marked by wide cerebral palsy, the symptoms of miosis, the pupillary contraction is marked by hyperopia, the pupillary is judged by the same as the cerebral palsy, the unilateral hyperopia, the pupillary is also has the sign, the cerebral palsy, the pupillary contraction is also has the sign is also shown in the sign, the cerebral palsy, the cerebral hemorrhage is also shown in the two symptoms of the cerebral hemorrhage, the cerebral hemorrhage is also shown in the hypopiesis, the unilateral palsy, the hypopiesis, the unilateral palsy, the lumbar depression, the hypopiesis.
