认识青光眼视野缺损的危险因素对于视功能损害的防治十分重要。研究表明,一旦出现视野缺损,视神经纤维丧失量已达50%,已不是青光眼病的早期。视野检查属心理物理学检测,其可靠性很大程度上依赖于医生的技能和患者的合作。因此,若能正确预测青光眼视野缺损的发生与否,则可及时调整治疗方案,有效地保护患者的视功能。青光眼视野缺损的发生发展受到多种因素的影响,如眼压、视乳头改变、青光眼家族史,以及某些全身情况等等,这些众多因素之间也存在着极其复杂的相互关系,迄今尚未能证实某一单一因素能够满意地预测视
Recognizing the risk factors for glaucomatous visual field defects is very important for the prevention and treatment of visual impairment. Studies have shown that in the event of visual field defects, loss of optic nerve fibers has reached 50%, is not early glaucoma. Vision examination is a psychophysical test, the reliability depends largely on the doctor’s skills and patient cooperation. Therefore, if the correct prediction of glaucomatous visual field defects occurred or not, you can adjust the treatment plan, effectively protect the patient’s visual function. The occurrence and development of glaucomatous visual field defects are affected by many factors, such as intraocular pressure, optic nerve changes, family history of glaucoma, and some general conditions, etc. There is also an extremely complicated relationship between these many factors, so far not yet Can confirm that a single factor can be satisfactorily predicted
