Visual fields

The percentage share of the inserts made austenite steel in the martensite structure is refered to the visual field of the probe in the given location. Every probe after performance is given a characteristics, in which the visual field is given, determined using special devices defining the visual field at different distances from the tested object. [Pg.22]

The visual field inspection of derrick or mast and substructure procedure is recommended for use by operating personnel (or a designated representative) to the extent that its use satisfies conditions for which an inspection is intended. A sample report form for this inspection procedure can be found in API Standard 4F. Forms are also available from International Association of Drilling Contractors (lADC). [Pg.517]

DISTUR0ED SENSORY PERCEPTION VISUAL. The patient taking chloroquine may experience a number of visual disturbances, such as disturbed color vision, blurred vision, night blindness, diminished visual fields, or optic atrophy. The nurse questions die patient about visual disturbances. [Pg.145]

Visual fields 0 = no visual loss 1 = partial hemianopia 2 = complete hemianopia 3 = bilateral hemianopia... [Pg.59]

Patients may also suffer from dysarthria, visual field defects, and altered levels of consciousness. [Pg.165]

In patients with macroprolactinomas, monitor visual field at baseline and repeat the test 1 month after initiation of a dopamine agonist. [Pg.719]

Optic nerve head and nerve fiber layer changes occur before visual field changes can be detected. [Pg.913]

Automated static threshold perimetry evaluates visual fields useful in diagnosis and determining if there is disease progression. [Pg.913]

Evaluate diagnostic tests (e.g., IOP, visual fields, and optic nerve evaluations) to determine if the patient s current glaucoma therapy is effective. [Pg.922]

Paracentral scotoma A blind spot near the center of the visual field. [Pg.1573]

A 65-year-old male complains of losing his vision Retinal examination reveals optic nerve cupping. Peripheral vision loss is observed on visual field tests, and his intraocular pressure is increased. Following treatment with a drug, he has improved visual acuity and decreased intraocular pressure. [Pg.179]

Patients usually have multiple signs of neurologic dysfunction on physical examination. The specific deficits observed depend upon the area of the brain involved. Hemi- or monoparesis and hemisensory deficits are common. Patients with posterior circulation involvement may present with vertigo and diplopia. Anterior circulation strokes commonly result in aphasia. Patients may also experience dysarthria, visual field defects, and altered levels of consciousness. [Pg.170]

Most patients with pituitary failure (secondary hypothyroidism) have clinical signs of generalized pituitary insufficiency such as abnormal menses and decreased libido, or evidence of a pituitary adenoma such as visual field defects, galactorrhea, or acromegaloid features. [Pg.248]

Although IOP is a poor predictor of which patients will have visual field loss, the risk of visual field loss increases with increasing IOP. IOP is not constant it changes with pulse, blood pressure, forced expiration or coughing, neck compression, and posture. [Pg.732]

Open-angle glaucoma is slowly progressive and is usually asymptomatic until the onset of substantial visual field loss. Central visual acuity is maintained, even in late stages. [Pg.733]

Treatment is indicated for all patients with elevated IOP and characteristic optic disk changes or visual field defects. [Pg.734]

I walk with a cane because I now have trouble with stairs and slopes, and when something moves across my visual field I can lose my balance and fall. There are days when I cannot get out of bed, I m in such pain and so fatigued. [Pg.233]
