Twenty-seven symptoms of 859 treated hypertensive patients were evaluated using a self-administered questionnaire and correlated with the depression (DEP), free-floating anxiety (FFA), phobic anxiety (PHO), obsessionality (OBS) and extraversion (HYS) scores of the Middlesex Hospital Questionnaire. The psychological features were associated with 24 of the 27 symptoms, and the extent to which these measurements determined the presence of a symptom was calculated. DEP and FFA were correlated with most of the symptoms, PHO with weak limbs, blurred vision, slow walking pace, nocturia and a lessened interest in sex. HYS was positively associated with the frequency of sexual intercourse in men and negatively with complaints of dyspnoea, tingling in the limbs and a slow walking pace. OBS was only associated with diarrhoea.

Oral administration of 50 mg tartrazine to 122 patients with a variety of allergic disorders caused the following reactions: general weakness, heatwaves, palpitations, blurred vision, rhinorrhoea, feeling of suffocation, pruritus and urticaria. There was activation of the fibrinolytic pathway as shown by reduction of plasminogen with high pre-kallikrein and low kallikrein values. Reduction in complement activity (CH50) was seen in three out of sixteen reactions.

Diagnosis of zygomatic fractures in the emergency department is possible by history and clinical signs together with a routine series of facial bone x-ray films. Three case reports are submitted to illustrate this approach, one case with obvious clinical signs and x-ray findings and two "unclear" cases where either the physical findings or the x-ray findings were equivocal. There may be pain, tenderness, cheekbone displacement subconjuctive hemorrhage and numbness, enophthalmos, and blurred vision. A Water's view is recommended for x-ray films. Zygomatic fractures are best treated in five to seven days; eye signs indicate earlier treatment. To treat, expose the probable fracture site and reduce under direct vision. The zygoma can be immobilized by passing a Kirschner wire through the body of the zygoma medially towards and through the lateral wall of the nose and into the bony nasal septum.

Progressive multifocal leukoencephalopathy (PML) is a viral illness affecting principally cerebral white matter of patients, who have diminished immunologic resistance. A patient is presented, whose initial complaint was blurred vision. Relentless progression over a period of seven months to left hemianopsia, prosopagnosia, alexia with agraphia and eventually cortical blindness was observed. Accompanying the visual impairment was a steady deterioration of mental function. Sequential computerized axial tomography defined low density lesions in the occipital white matter with sparing of the cortical ribbon. As hemianopsia progressed to cortical blindness, the scans confirmed the evolution of bilaterial occipital lesions. The diagnosis was made clinically and established on histological and cultural grounds. Computerized tomography seems to be valuable in diagnosis and monitoring progress of PML.

Simple bedside measurements of blood pressure and systolic pressure response to the Valsalva maneuver will confirm a clinical impression of orthostatic hypotension. Careful questioning of the patient usually elicits other symptoms of autonomic nervous system dysfunction, such as impotence, urinary and fecal incontinence, constipation or diarrhea, blurred vision, or sweating changes. Drugs are the most common cause of autonomic dysfunction, and their benefits should be weighed against the severity of the dysfunction. In addition, diabetes mellitus, uremia, amyloidosis, acute intermittent porphyria, myeloma, tabes dorsalis, and alcohol-nutritional problems may produce symptoms of autonomic dysfunction. Thus, patients who present with autonomic features but no history of dysfunction-producing drugs should undergo complete laboratory evaluation. A regimen of tyramine or L-dopa or a diet rich in cheese, processed meats, and wine (a monoamine), coupled with a monoamine oxidase inhibitor have beneficial effects in patients with orthostatic hypotension due to preganglionic autonomic dysfunction. Patients who do not respond to catecholamine precursors have stable, isolated orthostatic hypotension or a polyneuropathy such as that caused by diabetes.

Timolol maleate, a potent beta-adrenergic antagonist, reduces intraocular pressure in rabbits. With topical application in one eye, a significant reduction in pressure is seen in the contralateral, untreated eye also. When used in conjunction with timolol, other adrenergic amines, such as norepinephrine and epinephrine, produce an additional hypotensive response. On the other hand, pretreatment with timolol does inhibit the ocular hypotensive response to topically applied albuterol. No further reduction in pressure is seen after application of this beta-adrenergic agonist to eyes pretreated with timolol. In a double-blind study with patients who had previously been receiving various medications for control of elevated intraocular pressures, timolol was as effective as pilocarpine in reducing intraocular tension. Many common complaints associated with pilocarpine therapy, including miosis, ocular irritation, and blurred vision, were not encountered with timolol therapy.

Characteristic visual symptoms and signs in 12 patients with neoplasms or aneurysms involving the optic tract are summarized. Blurred vision was the most common initial manifestation. Optic atrophy became apparent in 7 of the 12 patients. Most patients had uniocular central scotomas with reduced visual acuity, and 2 had homonymous scotomas. Field defects were frequently incomplete and incongruous, combining central scotomas with elements of homonymous and bitemporal amblyopias. Seven patients had endocrine disturbances and memory deficits in addition to their visual symptoms.

Patients present themselves with neurotologic symptoms which may be early and subtle indicators of active vestibular pathology. The frequently slighted complaints of light-headedness, imbalance and a floating sensation are as important as "true rotatory vertigo." Ear fullness, the most underinvestigated of neurotologic complaints may be a cardinal symptom. Occipital headaches are a frequent complaint of the dizzy patient. Blurred vision, and, in some severe peripheral disorders, diplopia are symptoms referrable to oculovestibular interaction. Visual stimulation intensifies vestibular symptoms. Stress may precipitate or increase dizziness in patients who have partially compensated for a vestibular deficit. Anxiety, fatigue and systemic illness are exemplary. Patient histories are presented to emphasize clinical relevance and therapeutic modalities.

When treating a patient with neuroleptics or tricyclic antidepressants, it is usually assumed that complaints of blurred vision can be ascribed to the anticholinergic side effects of these drugs. The authors present a patient treated with imipramine and trifluoperazine whose complaints of blurred vision led to the diagnosis of toxoplasma chorioretinitis.

To minimize the risk of visual loss in diabetic patients, recognition of early signs of oculopathy is essential. Diabetes-associated third-nerve palsy is manifested by unilateral ptosis and exotropia. Symptoms of closed-angle glaucoma are intense pain, halos around lights, and blurred vision. Open-angle glaucoma does not necessarily produce symptoms and is treated medically. A gradual decrease in visual acuity, sometimes associated with photophobia and difficulty in night driving, and monocular diplopia, are manifestations of cataract. The patient with "background" retinopathy usually complains of blurred or distorted central vision. Once the macula is involved, vision progressively decreases. Although the relationship of metabolic control to retinopathy has not been settled, evidence indicates that good medical control of the disease may delay onset of vascular complications.
