Visual field examination

The visual field inspection method is divided into dynamic and static inspection. Generally, the visual field inspection is dynamic, and each point of equal sensitivity is measured by the moving visual target, and the line of sight is connected with the line of sight, and the peripheral contour of the visual field is recorded. The static check is to determine the light sensitivity threshold of each point on a meridian, and connect the curve to get the depth concept of the visual field defect. The doctor is 1m away from the patient, sitting face to face, the patient's left eye seeing the doctor's right eye or the patient's right eye looking at the doctor's left eye, watching each other, keeping the eyes at the same level. Basic Information Specialist Category: Ophthalmic Examination Category: Applicable gender: whether men and women apply fasting: not fasting Tips: Maintain a normal diet and schedule. Normal value Covering the patient's eye, the doctor stretches out his hand and swings back and forth, moving from the outer circumference to the center in all directions between the two. When the patient notices the moment of the finger, he immediately informs that if the doctor's vision is normal, the patient can be in all aspects. Seeing the finger at the same time as the doctor indicates that the patient's field of vision is generally normal. Clinical significance Abnormal results: In the early stage of glaucoma, the central visual field examination showed the expansion of physiological blind spots and the exposure of physiological blind spots, and gradually progressed into flaming blind spots and bow-shaped dark spots. If the upper and lower arcuate dark points are connected to each other, a circular dark spot can be formed. Early wedge-shaped defects appear in the peripheral field of view, gradually narrowing the nasal field of view, narrowing the centripetality, and eventually leading to tubular vision, or even completely disappeared. Therefore, through the examination of visual field, fundus, intraocular pressure, anterior chamber angle, etc., the progress, treatment effect and prognosis of glaucoma disease can be understood. Need to check patients with glaucoma. Precautions Taboo before the test: emotionally irritable. Requirements for inspection: cooperate with a doctor. Inspection process The doctor is 1m away from the patient, sitting face to face, the patient's left eye seeing the doctor's right eye or the patient's right eye looking at the doctor's left eye, watching each other, keeping the eyes at the same level. Covering the patient's eye, the doctor stretches out his hand and swings back and forth, moving from the outer circumference to the center in all directions between the two. When the patient notices the moment of the finger, he immediately informs that if the doctor's vision is normal, the patient can be in all aspects. Seeing the finger at the same time as the doctor indicates that the patient's field of vision is generally normal. Not suitable for the crowd Inappropriate population: Patients with other diseased lesions.
