Narrow angle

The structure of PP-g-polystyrene was studied by wide and narrow angle x-ray diffractometry. The polystyrene component formed discrete amorphous structures, which were identified after chloromethylation [143]. Structure of Rayon-Styrene graft copolymer was characterized by IR, wide angle x-ray, and SEM, grafting occurred mainly in the amorphous regions of rayon [1441. 

To ensure quality control material suppliers and developers routinely measure such complex properties as molecular weight and its distribution, crystallinity and crystalline lattice geometry, and detailed fracture characteristics (Chapter 6). They use complex, specialized tests such as gel permeation chromatography (2, 3), wide- and narrow-angle X-ray diffraction, scanning electron microscopy, and high-temperature pressurized solvent reaction tests to develop new polymers and plastics applications.

The antianxiety drug s are contraindicated in patients with known hypersensitivity, psychoses, acute narrow-angle glaucoma, and shock. These drugp are also contraindicated in patients in a coma or with acute alcoholic intoxication with depression of vital signs. 

The antihistamines are used cautiously in patients with bronchial asthma, cardiovascular disease, narrow-angle glaucoma, symptomatic prostatic hypertrophy, hypertension, impaired kidney function, peptic ulcer, urinary... 

Succinylcholine 1-1.5 mg/kg IV up to 150 mg total dose ° Contraindications may include use in patients with a personal or family history of malignant hyperthermia, extensive/severe burns, myopathies with elevated creatine phosphokinase, penetrating eye injuries, pre-existing hyperkalemia, narrow-angle glaucoma, and disorders of plasma pseudocholinesterase... 

Inhaled anticholinergics are well tolerated with the most common adverse effect being dry mouth. Occasional metallic taste has also been reported with ipratropium. Other anticholinergic adverse effects include constipation, tachycardia, blurred vision, and precipitation of narrow-angle glaucoma symptoms. Urinary retention could be a problem, especially for those with concurrent bladder outlet obstruction. 

Contraindications include hypertension, tachyarrhythmias, coronary artery disease, Ml, cor pulmonale, hyperthyroidism, renal failure, narrow-angle glaucoma... 

Suicide risk even in patients without psychiatric disease Avoid in uncontrolled narrow-angle glaucoma (causes mydriasis) Hepatotoxic avoid in alcoholics even if signs/symptoms of hepatic disease are absent. 

A variety of disorders may lead to rapid, painless, monocular or binocular vision loss. This may include central retinal artery occlusion, acute narrow-angle glaucoma, trauma, or others. The differential diagnosis is complex and needs to be undertaken by an emergency department or ophthalmologist.9... 

The most common side effects are ataxia, impaired concentration, confusion, memory difficulties, dizziness, fatigue, paresthesias, and somnolence. Nephrolithiasis occurs in 1.5% of patients. It has also been associated with acute narrow-angle glaucoma, oligohidrosis, and metabolic acidosis. 

For closed-angle glaucoma, the presence of a narrow angle is usually visualized by gonioscopy. IOP is generally markedly elevated (e.g., 40 to 90 mm Hg) when symptoms are present. Additional signs include hyperemic conjunctiva, cloudy cornea, shallow anterior chamber, and occasionally edematous and hyperemic optic disk. 

Exacerbation of narrow-angle glaucoma can occur with use of antipsy-chotics or AChs. 

Urinary retention gastric retention uncontrolled narrow-angle glaucoma hypersensitivity to the drug or its ingredients. 

Controlled narrow-angle glaucoma Use with caution in patients being treated for narrow-angle glaucoma. 

Narrow-angle glaucoma In patients being treated for narrow-angle glaucoma, only use trospium if the potential benefits outweigh the risks and, in that circumstance, only with careful monitoring. 

In patients with urinary retention, gastric retention, or uncontrolled narrow-angle glaucoma and in patients who are at risk for these conditions known hypersensitivity to the drug or its ingredients. 

Special risk Ipratropium bromide nasal spray should be used with caution in patients with narrow-angle glaucoma, prostatic hypertrophy, or bladder neck obstruction.
