Glaucoma challenge test

The stimulation test of glaucoma glaucoma is based on the pathogenesis of different types of glaucoma. Applicable methods are applied to people suspected of certain types of glaucoma, and targeted measures are taken to stimulate the increase of intraocular pressure to facilitate early diagnosis. The subject wears a black eye mask to sit in the dark room for 1 to 2 hours (one hour for young people, the pupils of the elderly are small, and the torso is not easy to dilute, it is suitable for 2 hours), can not sleep, must stay awake, otherwise it will affect the test. the result of. Basic Information Specialist Category: Ophthalmic Examination Category: Other Inspections Applicable gender: whether men and women apply fasting: not fasting Tips: Before the check, the taboos are emotionally intense. Normal value There are more women in the angle-closure type than men in the open-angle type, more women in the 40-year-old and more women in the angle of closure; those under the age of 30 are congenital glaucoma. There are more angle-closure types in hyperopia; more open-angle types in myopia, more angle-closure glaucoma in high-distance hyperopia; and open-angle glaucoma in high myopia. Clinical significance Abnormal results In most cases, acute signs such as segmental iris atrophy, glaucoma plaque, and vertical pupil dilation were left on the iris. Need to check the population suspected glaucoma patients. Precautions Taboo before the test: emotionally nervous. Requirements for inspection: The light is dark. Inspection process The subject wears a black eye mask to sit in the dark room for 1 to 2 hours (one hour for young people, the pupils of the elderly are small, and the torso is not easy to dilute, it is suitable for 2 hours), can not sleep, must stay awake, otherwise it will affect the test. the result of. After the test, the intraocular pressure should be rapidly measured under red light (dark light), and the increase of 1.25 kPa (8 mmHg) is positive. The positive patients should observe the change of the angle of the eye in addition to the difference of intraocular pressure before and after the test. It is best to observe with the narrowest slit light to avoid affecting the observation. Not suitable for the crowd Inappropriate people: elderly people with cardiovascular disease.
