How does Guangzhou Ophthalmology Department check refractive problems?
Guangzhou is an important city in southern China, with many high-quality ophthalmic hospitals. When people have blurred vision, eye fatigue and other problems, they often need to go to the ophthalmology department for examination. Refraction is one of the common vision problems, and Guangzhou Eye Hospital can accurately diagnose and treat refractive problems through a series of examination methods.
1. Computer vision examination
Computer vision examination is a common preliminary screening method, which can quickly obtain people's vision. In the Guangzhou Eye Hospital, doctors will ask patients to sit in front of the computer and observe their vision level through the patterns and letters on the display. In this way, doctors can initially determine whether there is a refractive problem.
If there is any abnormality in the preliminary examination, the doctor will further use the automatic optometer for more detailed examination. This instrument can quickly measure the patient's degree to determine whether there are refractive problems such as myopia, hyperopia or astigmatism.
In addition, some ophthalmic hospitals also provide computer vision training services to help patients improve their vision problems through specific computer programs and training methods.
2. Dynamic vision examination
Dynamic vision examination is a more comprehensive method of refractive examination. In Guangzhou Eye Hospital, doctors usually use automatic optometer and computer aided system to evaluate patients' vision problems through a series of test items.
Among them, common test items include night vision test, contrast sensitivity test, visual field test, etc. Through these tests, doctors can more accurately detect the type and extent of refractive problems.
The results of dynamic vision examination can provide an important basis for doctors to develop personalized treatment plans. In Guangzhou Eye Hospital, doctors usually provide glasses, corneal shaping glasses, laser treatment, etc. according to the specific conditions of patients.
3. Corneal topography examination
Corneal topography is an important refractive test method. In the Guangzhou Eye Hospital, doctors will use professional corneal topographic mapping equipment to examine the patients' eyes in detail.
Corneal topographic map can intuitively display the corneal shape and curvature of the eye. By analyzing the data of the topographic map, doctors can understand the characteristics of the patient's eyes and the causes of refractive problems.
In addition, corneal topography can also monitor the changes of patients in the treatment process, providing guidance for doctors to adjust the treatment plan.
4. Fundus examination
Fundus examination is an examination method to judge refractive problems by observing the fundus. In the Guangzhou Eye Hospital, doctors will use professional fundus cameras or microphotography equipment to take pictures and observe the patient's fundus.
Through fundus examination, doctors can find out the patients' ocular vascular abnormalities, macular lesions, and other ocular problems caused by refractive problems. This is very important for determining the treatment plan and preventing complications.
To sum up, Guangzhou Eye Hospital can comprehensively and accurately check refractive problems through computer vision examination, vision dynamic examination, corneal topography examination, fundus examination and other methods. These examination methods can not only judge the type and degree of refractive problems, but also help doctors to develop personalized treatment plans and provide accurate vision correction and treatment services for patients.
