How to quickly understand Guangzhou ophthalmic examination chart

Ophthalmic examination is an important part of protecting eye health. For the average person, the ophthalmic examination sheet may seem complicated, but as long as you understand the core concepts and learn to interpret them correctly, you can quickly understand the examination results. This article will introduce how to quickly understand Guangzhou ophthalmic examination sheet from four aspects.

Vision test

Vision is one of the most basic functions of the eye, and it is also the most easily understood part of the eye examination chart. In the checklist, "Uncorrected Visual Acuity (UCVA)" and "Best Corrected Visual Acuity (BCVA)" are the main indicators of vision test. UCVA reflects the uncorrected real vision level, while BCVA is the vision level after correction through glasses or contact lenses. Generally speaking, the larger the number, the better the eyesight.

In addition to vision indicators, there are also some other indicators in the eye examination chart, such as visible spectrum and color vision defect test. The visible spectrum shows the range of colors that can be perceived by the human eye, which is generally presented by chromatogram. Color vision defect test is used to detect color blindness or color weakness.

intraocular pressure

Intraocular pressure test is a common ophthalmic examination method used to assess intraocular pressure. Abnormal intraocular pressure may lead to glaucoma and other diseases. In the ophthalmic examination chart, "intraocular pressure (IOP)" is generally taken as the index for intraocular pressure test. The normal intraocular pressure range is generally 10-21 mmHg. If the intraocular pressure exceeds the normal range, further examination may be required to determine whether there is abnormal intraocular pressure.

Fundus examination

Fundus examination is one of the important means to evaluate the ocular structure and lesions. In the eye examination chart, fundus examination generally takes "fundus photography", "fundus color ultrasound" and "fundus OCT" as the main indicators, which can help doctors observe and evaluate the fundus structure. Through fundus examination, doctors can learn about the normal or abnormal conditions of retina, optic nerve and other structures, providing reference for subsequent treatment.

Fundus examination often requires professional interpretation by doctors, but we can learn some basic information from the ophthalmic examination chart, such as the overall situation of fundus structure, whether there are lesions, etc. Therefore, for ordinary people, the fundus checklist can be used as a reference for their own eye health.

Summary

From the above introduction, we can see that it is not difficult to understand the Guangzhou Ophthalmology Checklist. We only need to pay attention to the indicators of vision test, understand the normal range of intraocular pressure, and the meaning of each indicator in the fundus examination chart to roughly understand our own eye health. Of course, if there is anything you don't understand, it is recommended to consult a professional ophthalmologist in time. To keep your eyes healthy, start by reading the eye checklist!
