眼压操作流程及标准
英文回答:
Eye pressure, also known as intraocular pressure (IOP),
is a vital measurement in ophthalmology. It refers to the
pressure within the eye, which is determined by the balance
between the production and drainage of the aqueous humor,
the fluid inside the eye. Abnormal eye pressure can lead to
various eye conditions, including glaucoma, a serious eye
disease that can cause vision loss if left untreated.
The process of measuring eye pressure involves using a
device called a tonometer. There are different types of
tonometers, but the most common method is the Goldmann
applanation tonometry. In this method, the patient is
seated comfortably and numbing eye drops are administered
to the eye to reduce any discomfort. The tonometer, which
consists of a small probe attached to a device, is then
gently placed on the cornea. The device measures the force
required to flatten a small area of the cornea, which is
directly related to the eye pressure.
The standard range for normal eye pressure is typically
between 10 and 21 mmHg (millimeters of mercury). However,
it is important to note that individual variations exist,
and some people may have higher or lower baseline eye
pressures without any signs of eye disease. In cases where
the eye pressure is consistently above the normal range,
further evaluation is required to determine if it is
indicative of glaucoma or other eye conditions.
If elevated eye pressure is detected, additional tests
may be performed to assess the health of the optic nerve
and the visual field. These tests can help determine if
there is any damage to the eye as a result of increased
pressure. Treatment options for elevated eye pressure
depend on the underlying cause and may include the use of
eye drops, oral medications, laser therapy, or surgery.
Regular eye examinations are crucial in monitoring eye
pressure and detecting any changes that may indicate the
presence of eye conditions. It is recommended to have a
comprehensive eye exam, including eye pressure measurement,
at least once every two years for individuals aged 18 to 60,
and annually for individuals over 60 or those with known
risk factors for eye diseases.

眼压,也称为眼内压力(IOP),是眼科学中的一个重要指标。
它指的是眼睛内部的压力,由房水(眼内液体)的产生和排泄之间
的平衡决定。异常的眼压可能导致各种眼部疾病,包括青光眼,这
是一种严重的眼病,如果不及时治疗可能导致视力丧失。
测量眼压的过程涉及使用一种称为眼压计的设备。有不同类型
的眼压计,但最常用的方法是Goldmann凹面压平法。在这种方法中,
患者舒适地坐着,给眼睛滴上麻醉眼药水以减轻不适感。然后,轻
轻地将由探头和设备组成的眼压计放在角膜上。设备测量了压平角
膜的小区域所需的力量,这与眼压直接相关。
正常眼压的标准范围通常在10到21毫米汞柱(mmHg)之间。
然而,需要注意的是,个体差异是存在的,有些人可能具有更高或
更低的基线眼压而没有任何眼病的迹象。如果眼压持续超过正常范
围,需要进一步评估以确定是否提示青光眼或其他眼部疾病。
如果检测到眼压升高,可能会进行其他测试以评估视神经和视
野的健康状况。这些测试可以帮助确定是否由于眼压增高而导致眼
部损伤。治疗升高的眼压取决于潜在原因,可能包括使用眼药水、
口服药物、激光治疗或手术。
定期眼科检查对于监测眼压并检测任何变化以指示眼部疾病的
存在至关重要。建议18至60岁的人每两年进行一次全面的眼科检
查,包括眼压测量,60岁以上的人或已知眼部疾病风险因素的人每
年进行一次。
