Anisocoria: 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.Reflex, Pupillary: 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)Pupil: The aperture in the iris through which light passes.Adie Syndrome: A syndrome characterized by a TONIC PUPIL that occurs in combination with decreased lower extremity reflexes. The affected pupil will respond more briskly to accommodation than to light (light-near dissociation) and is supersensitive to dilute pilocarpine eye drops, which induce pupillary constriction. Pathologic features include degeneration of the ciliary ganglion and postganglionic parasympathetic fibers that innervate the pupillary constrictor muscle. (From Adams et al., Principles of Neurology, 6th ed, p279)Oculomotor Nerve Diseases: Diseases of the oculomotor nerve or nucleus that result in weakness or paralysis of the superior rectus, inferior rectus, medial rectus, inferior oblique, or levator palpebrae muscles, or impaired parasympathetic innervation to the pupil. With a complete oculomotor palsy, the eyelid will be paralyzed, the eye will be in an abducted and inferior position, and the pupil will be markedly dilated. Commonly associated conditions include neoplasms, CRANIOCEREBRAL TRAUMA, ischemia (especially in association with DIABETES MELLITUS), and aneurysmal compression. (From Adams et al., Principles of Neurology, 6th ed, p270)Horner Syndrome: A syndrome associated with defective sympathetic innervation to one side of the face, including the eye. Clinical features include MIOSIS; mild BLEPHAROPTOSIS; and hemifacial ANHIDROSIS (decreased sweating)(see HYPOHIDROSIS). Lesions of the BRAIN STEM; cervical SPINAL CORD; first thoracic nerve root; apex of the LUNG; CAROTID ARTERY; CAVERNOUS SINUS; and apex of the ORBIT may cause this condition. (From Miller et al., Clinical Neuro-Ophthalmology, 4th ed, pp500-11)Iris: The most anterior portion of the uveal layer, separating the anterior chamber from the posterior. It consists of two layers - the stroma and the pigmented epithelium. Color of the iris depends on the amount of melanin in the stroma on reflection from the pigmented epithelium.Ophthalmoplegia: Paralysis of one or more of the ocular muscles due to disorders of the eye muscles, neuromuscular junction, supporting soft tissue, tendons, or innervation to the muscles.Dark Adaptation: Adjustment of the eyes under conditions of low light. The sensitivity of the eye to light is increased during dark adaptation.Encyclopedias as Topic: Works containing information articles on subjects in every field of knowledge, usually arranged in alphabetical order, or a similar work limited to a special field or subject. (From The ALA Glossary of Library and Information Science, 1983)MedlinePlus: NATIONAL LIBRARY OF MEDICINE service for health professionals and consumers. It links extensive information from the National Institutes of Health and other reviewed sources of information on specific diseases and conditions.Light: That portion of the electromagnetic spectrum in the visible, ultraviolet, and infrared range.Eye: The organ of sight constituting a pair of globular organs made up of a three-layered roughly spherical structure specialized for receiving and responding to light.Tonic Pupil: A pupillary abnormality characterized by a poor pupillary light reaction, reduced accommodation, iris sector palsies, an enhanced pupillary response to near effort that results in a prolonged, "tonic" constriction, and slow pupillary redilation. This condition is associated with injury to the postganglionic parasympathetic innervation to the pupil. (From Miller et al., Clinical Neuro-Ophthalmology, 4th ed, pp492-500)Diplopia: A visual symptom in which a single object is perceived by the visual cortex as two objects rather than one. Disorders associated with this condition include REFRACTIVE ERRORS; STRABISMUS; OCULOMOTOR NERVE DISEASES; TROCHLEAR NERVE DISEASES; ABDUCENS NERVE DISEASES; and diseases of the BRAIN STEM and OCCIPITAL LOBE.Reflex, Abnormal: An abnormal response to a stimulus applied to the sensory components of the nervous system. This may take the form of increased, decreased, or absent reflexes.Mydriasis: Dilation of pupils to greater than 6 mm combined with failure of the pupils to constrict when stimulated with light. This condition may occur due to injury of the pupillary fibers in the oculomotor nerve, in acute angle-closure glaucoma, and in ADIE SYNDROME.Surgery, Oral: A dental specialty concerned with the diagnosis and surgical treatment of disease, injuries, and defects of the human oral and maxillofacial region.Nasolacrimal Duct: A tubular duct that conveys TEARS from the LACRIMAL GLAND to the nose.Tooth Extraction: The surgical removal of a tooth. (Dorland, 28th ed)Molar, Third: The aftermost permanent tooth on each side in the maxilla and mandible.Multimedia: Materials, frequently computer applications, that combine some or all of text, sound, graphics, animation, and video into integrated packages. (Thesaurus of ERIC Descriptors, 1994)Pupil Disorders: 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.Mydriatics: Agents that dilate the pupil. They may be either sympathomimetics or parasympatholytics.p-Hydroxyamphetamine: Amphetamine metabolite with sympathomimetic effects. It is sometimes called alpha-methyltyramine, which may also refer to the meta isomer, gepefrine.Autonomic Fibers, Postganglionic: Nerve fibers which project from cell bodies of AUTONOMIC GANGLIA to SYNAPSES on target organs.Receptors, Adrenergic, alpha: One of the two major pharmacological subdivisions of adrenergic receptors that were originally defined by the relative potencies of various adrenergic compounds. The alpha receptors were initially described as excitatory receptors that post-junctionally stimulate SMOOTH MUSCLE contraction. However, further analysis has revealed a more complex picture involving several alpha receptor subtypes and their involvement in feedback regulation.Oculomotor Nerve: The 3d cranial nerve. The oculomotor nerve sends motor fibers to the levator muscles of the eyelid and to the superior rectus, inferior rectus, and inferior oblique muscles of the eye. It also sends parasympathetic efferents (via the ciliary ganglion) to the muscles controlling pupillary constriction and accommodation. The motor fibers originate in the oculomotor nuclei of the midbrain.Allied Health Occupations: Occupations of medical personnel who are not physicians, and are qualified by special training and, frequently, by licensure to work in supporting roles in the health care field. These occupations include, but are not limited to, medical technology, physical therapy, physician assistant, etc.Allied Health Personnel: Health care workers specially trained and licensed to assist and support the work of health professionals. Often used synonymously with paramedical personnel, the term generally refers to all health care workers who perform tasks which must otherwise be performed by a physician or other health professional.Health Priorities: Preferentially rated health-related activities or functions to be used in establishing health planning goals. This may refer specifically to PL93-641.Referral and Consultation: The practice of sending a patient to another program or practitioner for services or advice which the referring source is not prepared to provide.Cats: The domestic cat, Felis catus, of the carnivore family FELIDAE, comprising over 30 different breeds. The domestic cat is descended primarily from the wild cat of Africa and extreme southwestern Asia. Though probably present in towns in Palestine as long ago as 7000 years, actual domestication occurred in Egypt about 4000 years ago. (From Walker's Mammals of the World, 6th ed, p801)Encephalitis: Inflammation of the BRAIN due to infection, autoimmune processes, toxins, and other conditions. Viral infections (see ENCEPHALITIS, VIRAL) are a relatively frequent cause of this condition.Inflammation: A pathological process characterized by injury or destruction of tissues caused by a variety of cytologic and chemical reactions. It is usually manifested by typical signs of pain, heat, redness, swelling, and loss of function.Cat Diseases: Diseases of the domestic cat (Felis catus or F. domesticus). This term does not include diseases of the so-called big cats such as CHEETAHS; LIONS; tigers, cougars, panthers, leopards, and other Felidae for which the heading CARNIVORA is used.Rupture, Spontaneous: Tear or break of an organ, vessel or other soft part of the body, occurring in the absence of external force.Brain: The part of CENTRAL NERVOUS SYSTEM that is contained within the skull (CRANIUM). Arising from the NEURAL TUBE, the embryonic brain is comprised of three major parts including PROSENCEPHALON (the forebrain); MESENCEPHALON (the midbrain); and RHOMBENCEPHALON (the hindbrain). The developed brain consists of CEREBRUM; CEREBELLUM; and other structures in the BRAIN STEM.Microglia: The third type of glial cell, along with astrocytes and oligodendrocytes (which together form the macroglia). Microglia vary in appearance depending on developmental stage, functional state, and anatomical location; subtype terms include ramified, perivascular, ameboid, resting, and activated. Microglia clearly are capable of phagocytosis and play an important role in a wide spectrum of neuropathologies. They have also been suggested to act in several other roles including in secretion (e.g., of cytokines and neural growth factors), in immunological processing (e.g., antigen presentation), and in central nervous system development and remodeling.Los AngelesOphthalmology: A surgical specialty concerned with the structure and function of the eye and the medical and surgical treatment of its defects and diseases.Cellular Phone: Analog or digital communications device in which the user has a wireless connection from a telephone to a nearby transmitter. It is termed cellular because the service area is divided into multiple "cells."

Proximal M2 false aneurysm after head trauma--Case report. (2/20)

A 72-year-old male presented with a post-traumatic false aneurysm of the right proximal M2 artery with massive subarachnoid hemorrhage after closed head injury. Serial computed tomography (CT) and angiography showed the development of the aneurysm which was verified at autopsy. He was admitted in a drowsy state just after a motorcycle accident. Initial brain CT showed subarachnoid hemorrhage without skull fracture. Follow-up brain CT showed a huge hematoma in the right temporal lobe. He died 47 hours after the accident. Histological examination of the aneurysm showed a false aneurysm. Delayed diagnosis of traumatic aneurysms leads to high mortality, so early surgical treatment is essential to save such patients.  (+info)

Late detection of supraclinoid carotid artery aneurysm after traumatic subarachnoid hemorrhage and occlusion of the ipsilateral cervical internal carotid artery. (3/20)

BACKGROUND AND PURPOSE: We report the first case of traumatic aneurysm of the supraclinoid internal carotid artery (ICA), which we speculate may have developed or grown after traumatic occlusion of the ipsilateral cervical ICA. CASE DESCRIPTION: A 26-year-old man presented with severe traumatic subarachnoid hemorrhage (SAH) and occlusion of the right cervical ICA after a motor vehicle accident. Three-dimensional CT angiography on admission showed no aneurysm. However, cerebral angiography 3 weeks after the injury showed a large aneurysm of the right supraclinoid ICA. The aneurysm was trapped, and pathological examination showed that it was a traumatic aneurysm. CONCLUSIONS: In this case we cannot be sure that the aneurysm was not present on admission. In view of the significant SAH, a lesson of this case may be to suspect such an aneurysm early on and perform early diagnostic cerebral angiography.  (+info)

Pupillary evaluation for differential diagnosis of coma. (4/20)

OBJECTIVES: To determine the usefulness of bedside evaluation of pupils in determining the aetiology of coma by adopting a probabilistic approach. PATIENTS AND METHODS: One hundred and fifteen consecutive patients presenting with coma were enrolled in this prospective cohort during the 12 month study period in the emergency room of a community teaching hospital. Patients underwent structured clinical examinations and laboratory and imaging tests. Assignment of aetiology of coma was based on strict adherence to predetermined criteria and achieved by consensus of the two physician investigators. One year follow up was obtained in all patients. RESULTS: Aetiology of coma was determined in 98% of the patients. It was metabolic in 69 patients (60%) and structural in 46 patients (40%). Metabolic causes included drug overdose, acute alcohol intoxication, hypoglycaemia, sepsis, and pneumonia. Structural causes included intracerebral haemorrhage, subarachnoid haemorrhage, cerebral infarction, subdural haematoma, and epidural haematoma. Multivariate logistic regression analysis showed light reflex loss (likelihood ratio for positive test result 3.59) and anisocoria (likelihood ratio for positive test result 9.0) as independent predictors of structural origin. CONCLUSIONS: In this prospective study of patients presenting to the emergency room of a community based teaching hospital with coma, in about 60% the coma is of metabolic origins and in about 40% of structural origins. Light reflex loss and anisocoria suggest a structural aetiology.  (+info)

The sensitivity and specificity of 0.5% apraclonidine in the diagnosis of oculosympathetic paresis. (5/20)

AIMS: To evaluate the sensitivity and specificity of 0.5% apraclonidine test in the diagnosis of oculosympathetic paresis (OSP). METHOD: Apraclonidine (0.5%) was administered to 31 eyes, nine with a diagnosis of Horner syndrome (HS), 22 with bilateral OSP caused by diabetes, and to 54 control eyes. All were confirmed with the cocaine test. The effects on pupil diameter and upper eyelid level were observed 1 hour later. RESULTS: Apraclonidine caused a mean dilation of 2.04 mm (range 1--4.5) (p<0.001) in the pupils with OSP and it caused pupillary constriction in the control eyes with a mean change of -0.14 mm (range 0.5 to --1) (p<0.05). It caused reversal of anisocoria in all HS cases. Its effects on both pupil diameters and upper lid levels differed significantly between the groups (p<0.001). The mean elevation in the upper lid was 1.75 mm (range 1--4) in the OSP group (p<0.001) and 0.61 mm (range 0--3) in the control group (p<0.001). CONCLUSION: The effect of the apraclonidine (0.5%) test on the pupil diameter was diagnostic for OSP and had at least the same sensitivity and specificity as the cocaine test for the diagnosis of OSP.  (+info)

When cluster headache was called histaminic cephalalgia (Horton's headache). (6/20)

The Author revives his experiences and reminiscences in the frontline research and everyday clinical practice dealing with what was then called "histaminic cephalalgia" (Horton's headache). In this context, the Author, one of the historical representatives of the School of Florence, reports an outline of the contribution of this pioneering period in order to promote research ideas concerning possible brain involvement in cluster headache (CH) pathogenesis, which is currently accepted worldwide. The recent history of CH has registered remarkable progress in revealing the mystery of this pathology and it is likely that, in the near future, through the development of better education and new treatments, the overall suffering of patients will be further minimised.  (+info)

Bilateral tonic pupils: Holmes Adie syndrome or generalised neuropathy? (7/20)

AIM: To compare the pupil signs in patients with bilateral pupillotonia caused by Holmes-Adie syndrome or generalised peripheral neuropathy. METHODS: Infrared video pupillographic techniques were used to measure a number of pupil variables in patients with Holmes-Adie syndrome, generalised neuropathy (various aetiologies) and healthy age-matched control subjects. RESULTS: Regardless of aetiology, the patients generally had pupil signs typical of pupillotonia (small dark diameters, large light diameters, tonic near responses, attenuated light responses with light-near dissociation, and sector palsy). However, significant differences were found in the prevalence and magnitude of several pupil variables in the two patient groups. In particular, sector palsy and anisocoria exceeding 1 mm (in the light) were seen much more commonly in Holmes-Adie patients than patients with generalised neuropathy. The presence of both these pupil signs can be used to distinguish between these diagnoses with a sensitivity of 58% and a specificity of 90%. CONCLUSIONS: The tonic pupils of patients with Holmes-Adie syndrome are significantly different to those found in patients with generalised neuropathy; recognition of these differences may allow distinction between these diagnoses.  (+info)

Sex-specific lateralization of contraction anisocoria in transient pupillary light reflex. (8/20)

 (+info)

A relative afferent pupillary defect (RAPD) also known as a Marcus Gunn pupil does not cause anisocoria. Some of the causes of anisocoria are life-threatening, including Horners syndrome (which may be due to carotid dissection) and oculomotor nerve palsy (due to a brain aneurysm, uncal herniation, or head trauma). If the examiner is unsure whether the abnormal pupil is the constricted or dilated one, and if a one-sided ptosis is present then the abnormally sized pupil can be presumed to be the one on the side of the ptosis. This is due to the fact that Horners syndrome and oculomotor nerve lesions both cause ptosis. Anisocoria is usually a benign finding, unaccompanied by other symptoms (physiological anisocoria). Old face photographs of patients often help to diagnose and establish the type of anisocoria. It should be considered an emergency if a patient develops acute onset anisocoria. These cases may be due to brain mass lesions which cause oculomotor nerve palsy. Anisocoria in the presence ...
Some cases reported in literature confirm unilateral mydriasis after the spread of phenylephrine nose drops through the nasolacrimal duct. These drops were used for mucosal vasoconstriction. 8. Unilateral mydriasis was also reported after using phenylephrine/lidocaine spray with a standard oxygen-driven face mask nebulizer. 9. Literature shows that the cases of anisocoria reported during or after oral surgery are rare occurrences, especially in cases of simple tooth extraction. It also indicates the absence of a case history allowing the oral surgeon to make a differential diagnosis, in case he has to diagnose this clinical condition.. Among the few cases of anisocoria after oral surgery under general anesthesia, we report a unilateral mydriasis together with eye movement disorders in a patient treated with regional anesthesia with lidocaine and epinephrine for surgical removal of impacted third molars. 10. For investigation and diagnosis of unilateral pupil dilation, the main causes that a ...

The authors present a pediatric case of acute anisocoria secondary to contact with the angels trumpet plant. This case report
Anisocoria is unequal pupil size. The pupil is the black part in the center of the eye. It gets larger in dim light and smaller in bright light.

After trauma to the eye, the iris tissue can be injured causing the pupil to not constrict to bright light normally. Another possible cause is Adies tonic pupil syndrome. This is a condition most common in young adult females, which usually begins in one eye. The pupil is sluggish to react to light. Many people with this condition will also have diminished deep tendon reflexes and they can have trouble focusing at near. The condition is usually not associated with any more serious conditions. Some eyedrops have a dilating effect on the pupil, so eyedrop use is another cause of a dilated pupil. Finally, an abnormality of the third cranial nerve (a nerve that comes from the brain to the eye socket and controls eyelid position, eye movement, and pupil size) can cause a pupillary abnormality. In this condition, there is often ptosis (droopiness) of the upper eyelid on the same side as the dilated pupil. In addition, the eye may not move normally and an older child might complain of double vision. A ...
Slight differences in pupil sizes are found in up to 1 in 5 healthy people. Most often, the diameter difference is less than 0.5 mm, but it can be up to 1 mm.. Babies born with different sized pupils may not have any underlying disorder. If other family members also have similar pupils, then the pupil size difference could be genetic and is nothing to worry about.. Also, for unknown reasons, pupils may temporarily differ in size. If there are no other symptoms and if the pupils return to normal, then it is nothing to worry about.. Unequal pupil sizes of more than 1 mm that develop later in life and do NOT return to equal size may be a sign of an eye, brain, blood vessel, or nerve disease. ...
The first thing you have to understand is the pupil in human eyes. The pupils in humans eyes are of the same size each other. The normal size of humans pupil is 2 to 6 mm and its shape is round. But, there is also a chance in which a person has one pupil smaller about 1 mm than the other and it is the normal thing which is called as anisocoria. The people who have anisocoria in the world is about 15% of global population. There are some irregular pupil size cases on the patients who have gone under the knife for cataract surgery.. In this case, to figure out whether a persons eyes are normal or not, the nurses in a hospital or any other health clinic will perform some procedures. There are some terms related to pupils normality, which are PERL, the acronym of Pupils Equal and Reactive to Light. The second is PERRLA, an acronym of Pupils Equal, Round and Reactive to Light and Accommodation. The third term is RAPD, which is the acronym of Relative Afferent Pupillary Defect. In this case, you ...

David Bowie has a condition called anisocoria, which is the medical term for unequal pupils. In 1962, aged 14, he got punched in the eye by his schoolfriend George Underwood, during an argument over a girl named Carol Goldsmith. Georges fingernail caught Davids eye and dislodged something. David was admitted to Farnborough Hospital, where it was found that the sphincter muscles of his left eye were badly torn and he underwent two eye operations. He has an enlarged pupil that remains permanently open, giving them an unusual appearance. Contrary to popular belief David doesnt have two different coloured eyes - they are both the same colour. The enlarged pupil only gives the "effect" of two different coloured eyes.. ...

Results: Among 220 patients, 53.2%, 30.9% and15.9% suffered mild, moderate and severe head injury. 50% patients developed secondary systemic insults (SSIs). Neurosurgical procedures were needed in 25% cases. Mortality was 20%, brain herniation being the leading cause. Univariate analysis showed need for mechanical ventilation, anisocoria, SSIs, and low Glasgow Coma Scale scores to be the strongest predictors of mortality (p values,0.0001). Multivariate analysis showed that moderate [RR 1.7 (95% CI 1.3-2.1), p,0.0001] and severe head injury [RR 2.0 (95% CI 1.6-2.5), p,0.0001], hyponatremia [RR 1.4 (95% CI 1.2-1.8), p=0.005], nosocomial infections [RR 1.5 (95% CI 1.3-1.9), p=0.002] and presence of midline shift in CT brain [RR 1.7 (95% CI 1.3-2.1), p=0.004] were the independent risk factors for development of poor outcome. 49% had good outcome with low disability (Glasgow outcome score 5) and 7.2% had post-traumatic seizure disorder ...

Authors: Miyamoto K, Kozu S, Arakawa A, Tsuboi T, Hirao JI, Ono K, Arisaka O.. Acute disseminated encephalomyelitis confined to the brainstem is associated with poor prognosis. We describe a case of a 10-year-old boy with acute disseminated encephalomyelitis in the brainstem that developed after influenza A infection. A 10-year-old boy presented with fever and prolonged disturbance of consciousness and was admitted to our hospital. Magnetic resonance imaging (MRI) of the midbrain, with T2-weighted and fluid-attenuated inversion recovery images, suggested acute disseminated encephalomyelitis accompanied by a brainstem lesion. Lumbar puncture showed pleocytosis and increased protein content, including myelin basic protein, interleukin-6, and immunoglobulin G, all suggestive of acute disseminated encephalomyelitis. Treatments such as methylprednisolone pulse therapy, intravenous immunoglobulin, and therapeutic hypothermia were performed. Although the patient presented with anisocoria with increased ...
RESULTS: Overall, 24 patients were treated. The mean age was 67.2 years; mean occlusion time, 230.2 minutes. On admission, the median NIHSS score was 18. In all patients, the Thrombolysis in Cerebral Infarction score was zero before the procedure. Stent implantation was feasible in all cases. In 15 patients (62.5%), a Thrombolysis in Cerebral Infarction score ≥ 2b could be achieved. Six patients (25%) improved ≥10 NIHSS points between admission and discharge. After 90 days, the median mRS score was 3.0. Seven patients (29.2%) had a good clinical outcome (mRS 0-2), and 4 patients (16.6%) died, 1 due to fatal intracranial hemorrhage. Overall, symptomatic intracranial hemorrhage occurred in 4 patients (16.6%). ...
Speaking of lenses, there is no need to spend ridiculous amounts of money on optics that have become the victim of a craze. Traditionally you have Kern-Paillard lenses with Paillard-Bolex equipment. The Yvar 75 mm, f/2.8 for example has lift off the ground of common sense. Never pay more than $300 for one of these unless its been serviced by someone who knows the stuff and grants a warranty on her/his work. After all, its only a triplet. The 100 mm and 150 mm Yvar are offered at entirely mad prices, up to $2,400. Stay away from that. Wide-angle lenses, most often consisting of six to eight elements, may cost more. The Kern Switar 10 mm is good but other makes are nice, too. I can recommend Schneider, Rodenstock (if you happen to stumble over one), Voigtländer, Zeiss, Leitz, Taylor-Hobson Cooke, Angénieux, and a few American ones. Berthiot are interesting, too, with some exceptions due to poor iris mechanics. Kinoptik can be had second-hand, individually matched elements lenses, therefore ...
This health and fitness thing is one of Americas biggest conundrums. We all say we want it, most of us could easily figure out how to get it, yet very few of us (people in this country) can live it. Especially in the long term. Were all very aware that choosing healthy food and exercise will improve our lives in hundreds of ways. Yet the daily battle continues for most of us. How do we make it automatic like sleep, eating and breathing? We cant. Its like work or traffic or family issues. It takes time, practice and patience. Super wealthy people get that way because they want it... badly. Achieving wealth, fitness, or even true happiness requires courage, determination and the willingness to fail often and being perfectly okay with that. Eating, sleeping and breathing is easy. Everybodys managing to do it. Healthy and fit people are rare these days because a vast majority of them dont have the right tools. No-one in this community has that excuse. You have the tools.

She is hard to miss - a small woman, probably less than 100 pounds - wearing many layers of clothing which make her look even tinier. She is small but strong; carrying several bags as she walks quickly down the streets. You have heard her mumbling to herself, or occasionally yelling at nobody in particular.. One day, you dont see her at the Tim Hortons. As the weeks pass, you wonder where she has gone…is she safe? Has anyone else noticed? You worry about the fate of this unknown woman. But she is not unknown. On the streets, she is known as La Petite Joanne - a kind and generous woman. She often shares her money with panhandlers and offers them her food. In turn, others on the streets look out for her and protect her.. By her family, she is known as Jocelyne. She grew up on the East coast, one of 10 children. She graduated high school and went on to become a secretary. Her career brought ...

This is a posting of a notice about the BIO-MATRIX project, its aims, and current activities. It appears irregularly.] BIO-MATRIX is not a database or a functional tool. The concepts underpinnings are best described in the Final Report of the Workshop on Matrix Biology. I will summarize here my interpretation of the Matrix concept. The Matrix of Biological Knowledge is a response to the way biologists reason about their systems. Physicists have recourse to first principles and in the last 20 years weve seen implications of quantum mechanics on the cosmological scale. The complexity of biological systems is such that its going to be a *long* time before one can reason a Tetrahymena from first principles. As each scientist thinks about their particular system, they consciously (and frequently unconsiously) reason about their system by analogy. A striking example of this appeared on the cover of Science; the three-dimensional structure of _ras_ is essentially identical to one proposed a few ...
Personally, I dont think this changes anything. Doesnt change the needs at QB and OL and as far as the defense goes most of us here may been considering players draft-wise in terms of how they fit in Hortons defense. Nothing there would change. I dont personally think this changes anything in terms of our off-season personnel thoughts. The offensive scheme may change (It may not either) but thatll have a very small effect on how we draft, if it has any effect at all. ...

Drop tests. Theres much to be said about how eye drops and other examination maneuvers can be used as aids in your differential diagnosis. Take a case of Horners Syndrome, for example. Most people just image the entire sympathetic pathway anyway, but its kind of interesting to know. So, by giving a patient 0.5% topical apraclonidine to both eyes, the affected eye by the Horners Syndrome will dilate to a much greater size than the contralateral pupil. This is due to subacute (,48hours) or chronic denervation of that eye leading to overexpression of alpha adrenergic receptors and hypersensitivity of that pupil to sympathetic stimulation. This confirms the Horners, but wont tell you where the lesion is. Next, you administer hydroxyamphetamine, which stimulates release of norepinephrine from the intact post-ganglionic neuron (3rd order neuron in the 3-neuron Horner pathway). If the affected pupil also dilates in response to these eye drops, then the 3rd order neuron is alive and thus the ...
HISTORY. A domestic shorthaired cat, four-month-old, male neutered, was referred to the 0phthalmology Service at the Veterinary Teaching Hospital of Murcia with a week history of ocular pain and swelling, anorexia and lethargy. Physical examination confirmed that clinical abnormalities were limited to the right eye and orbit.. The ophthalmic examination confirmed purulent and haemorrhagic discharge, third eyelid protrusion, chemosis and anisocoria with right miosis. The fotomotor reflexes revealed a negative right direct and consensual and left consensual pupillary light reflex. The intraocular pressures were 8 and 13 mm Hg in the right and left eye respectively, by applanation tonometry. Biomicroscopy revealed mild corneal edema, stromal vascularization, marked aqueous flare and miosis. Direct and indirect ophthalmoscopy examination were not possible, due to the opacity of the transparent media. An ocular and orbital ultrasonography using high frequency ultrasound transducer of 75 MHz was ...
Neuro-ophthalmologic disorders can arise from dysfunction of any part of the neuro-ophthalmologic tracts. The clinical signs may be decreased vision, blindness, abnormal pupillary light reflex, anisocoria, abnormal eye movements and strabismus alone or in association with multifocal neurological/systemic signs, depending on the distribution and type of lesion. A firm understanding about the neuroanatomy of the neuro-ophthalmologic pathways is essential to perform a correct neuroanatomic diagnosis. Based on the information obtained from signalment, a detailed history (including disease onset and progression), and physical, ophthalmic and neurological examination, the clinician can formulate a list of differential aetiologic diagnoses and subsequently select and interpret diagnostic investigations. The aetiologic diagnosis enables the initiation of specific treatment and predicting prognosis. Advances in diagnostic imaging have expanded the knowledge of neuro-ophthalmologic conditions. Prompt ...

Note that there is a characteristic delay in dilatation of the affected pupil (red line) after a light reflex in the patient with Hornerвs syndrome, but not in the patient with physiologic anisocoria. F. Arch Ophthalmol 1961; 66552. 6 References.
Clinical case: We report the case of a 78-years-old woman who presented to the emergency department with new onset anisocoria and flattened left nasolabial fold. Two hours before admission, she reported transient left sided paraesthesias and left arm weakness. Past medical history was relevant for hypertension, dyslipidaemia and unspecified arrhythmia, without anticoagulation therapy. Brain computed tomography (CT) showed basilar artery (BA) hyperdensity with no ischemic or haemorrhagic lesions and CT angiography confirmed top of BA occlusion. Despite minor neurological deficits (NIHSS 1), she started fibrinolytic therapy with recombinant tissue plasminogen activator (rt-PA) (0.9 mg/kg). She underwent cerebral angiography which showed recanalization of BA and occlusion of the P2 segment of left posterior cerebral artery (PCA). While attempting thrombectomy, spontaneous recanalization of P2 segment occurred with occlusion limited to P3/P4 segment and partial thrombus aspiration was performed. ...
We are pleased to announce the addition of the Spot Vision Testing Camera to our arsenal of diagnostic tools to help your family be its healthiest. The Spot device comes with a variety of clinical benefits over the Snellen chart. The most important benefit is that this device can be used for children who are unable to speak or read. Spot is a handheld device that works on children as young as 6 months of age up to adulthood. Spot is able to detect a variety of vision problems including nearsightedness, farsightedness and astigmatism. It can also detect unequal vision power (anisometropia), eye misalignment (amblyopia), unequal pupil size (anisocoria), and eye structure problems.. During the Spot exam, the child sits down and looks into the front of the device where blinking lights are shown. The device is held 3 feet away, which is great for youngsters who like their personal space. Next, a bird chirps to capture the attention of young children. In a matter of seconds a series of photos are ...

At the Spokane Eye Clinic we are equipped to diagnose and treat a wide range of neurological and systemically related visual disorders. We address vision loss from cerebrovascular disease, optic neuropathy, facial movement disorders including blepharospasm and hemifacial spasm, abnormal eye movements (gaze palsy and nystagmus), cranial nerve disorders, papilledema (increased intracranial pressure), optic disc edema, optic neuritis, unexplained vision loss and facial pain, myasthenia gravis, ptosis, and thyroid eye disease. We do pupil testing and photos for anisocoria, electrophysiology, ultrasound, and botox injections.. Neuro-Ophthalmology involves both neurology and ophthalmology specialties focusing on visual impairments that originate from the nervous system and or the eye, frequently resulting in dysfunction of the optic nerve. Visual impairments can be transient or permanent, and can range from visual distortion to visual field defects. Neuro-ophthalmology also addresses vision changes ...
Anisocoria in the absence of orbital trauma. Abnormalities in a cranial nerve reflex indicate injury to the brainstem or the neural pathway connecting to the brainstem. Multiple cranial nerve deficits is highly suggestive of brainstem injury. The two most useful cranial nerve reflexes for rapid assessment of brainstem function are the gag reflex and the presence of physiologic nystagmus, otherwise known as the oculocephalic reflex. If these two reflexes are absent it strongly indicates significant brainstem injury and a guarded prognosis.. The segmental spinal reflexes should be evaluated when possible, without excessive manipulation of the patient. Abnormalities in thoracic and/or pelvic limb reflexes will help identify spinal trauma. Cases of brain injury without spinal injury tend to have normal or possibly exaggerated spinal reflexes.. Decerebrate posture: patient has opisthotonos and extensor rigidity of all four limbs. The animal is unresponsive and does not detect deep pain sensation. ...
