deep examination of the anterior chamber

Anterior chamber axis depth test: Check with the anterior chamber depth tester or use the Jaeger meter attached to the Zeiss-Opton slit lamp to check the anterior chamber axis depth at a 45° observation angle. The normal eye is 2.5mm-3mm. The microscope is at an angle to the beam, and the slit lamp is moved along the axis of the eye to M, so that the A1 behind the cornea appears on the cross reading of the microscope, and then the slit lamp is moved forward to M, so that the front A2 of the crystal appears on the microscope. Upper, MM is the apparent anterior chamber depth, which can be converted into true anterior chamber depth based on corneal refractive power and aqueous humor refractive index. Basic Information Specialist Category: Ophthalmic Examination Category: Other Inspections Applicable gender: whether men and women apply fasting: not fasting Tips: Before eating, avoid eating spicy food and overeating. Normal value The anterior chamber axis was examined at a 45° viewing angle using an additional Jaeger gauge on a Zeiss-Opton slit lamp. The normal eye is 2.5mm-3mm. Clinical significance Abnormal results The anterior chamber is the space behind the cornea, the iris and the pupil, and the posterior chamber is behind the iris, the pupil, and the lens. The front and back rooms are filled with transparent liquid, which we call water. The angle of the occlusion is blocked, the drainage of the aqueous humor is blocked, and the intraocular pressure is increased, causing too much pressure on the wall of the eyeball, which causes damage to the optic nerve. Need to check the crowd of children with myopia, the elderly presbyopia. Precautions Taboo before the test: eat spicy food, eat too much. Requirements for inspection: Maintain a happy mood and cooperate with the doctor. Inspection process The microscope is at an angle to the beam, and the slit lamp is moved along the axis of the eye to M, so that the A1 behind the cornea appears on the cross reading of the microscope, and then the slit lamp is moved forward to M, so that the front A2 of the crystal appears on the microscope. Upper, MM is the apparent anterior chamber depth, which can be converted into true anterior chamber depth based on corneal refractive power and aqueous humor refractive index. Not suitable for the crowd Inappropriate crowd: no symptoms of inflammation, healthy eyes.
