General examination of the anterior chamber

The general examination of the anterior chamber is mainly to check the depth of the anterior chamber, the anterior chamber angle and the transparency of the aqueous humor. For the simple examination of the anterior chamber, the depth of the central anterior chamber can be estimated by the flashlight side view method, that is, the light of the hand-light is parallel to the iris at the outer iliac crest, and the depth of the anterior chamber is initially determined according to the range in which the iris is illuminated. Anterior chamber slit lamp microscopy The slit lamp microscope uses a strong direct light illumination method to adjust the band to narrow light. Basic Information Specialist Category: Ophthalmic Examination Category: Other Inspections Applicable gender: whether men and women apply fasting: not fasting Tips: The room has bright light and is a dark room. The time of the eye is not too long. Normal value Observe the depth of the central part of the anterior chamber. The normal anterior chamber depth is about 2.5~3.0mm. If it is less than 2mm, it may indicate that there is a possibility of angle-closure glaucoma. Further examination should be carried out. Clinical significance Abnormal results are normal. The anterior chamber is filled with transparent aqueous humor, but after the lesions such as inflammation or trauma in the eye, the aqueous humor may become cloudy or have hemorrhage or empyema. Mild turbidity cannot be seen with the naked eye. The accumulation of blood and empyema is deposited on the bottom of the anterior chamber due to gravity, and the liquid level that moves with the change of the head position can be seen by the naked eye. Need to see patients with glaucoma in the car population. Precautions Forbidden before inspection: There should be bright light in the room, which is a dark room. Requirements for inspection: The time of the eye is not too long. Inspection process For the simple examination of the anterior chamber, the depth of the central anterior chamber can be estimated by the flashlight side view method, that is, the light of the hand-light is parallel to the iris at the outer iliac crest, and the depth of the anterior chamber is initially determined according to the range in which the iris is illuminated. For anterior chamber slit lamp microscopy, the slit lamp microscope uses a direct light illumination method to adjust the band to narrow light. Not suitable for the crowd Inappropriate people: No special instructions can be checked by ordinary people.
