Medical principle of myopia table in Shanghai Eye Hospital
Shanghai Eye Hospital is a professional ophthalmic medical institution, which provides many innovative treatments for solving eye health problems. Among them, the myopia table, as a commonly used auxiliary inspection tool, plays an important role in the assessment and treatment of myopia patients. The medical principle of myopia table involves many aspects such as eye optics, corneal curvature and retinal imaging.
1. Basic principle of myopia watch
Myometer is a tool that uses a combination of red, green and blue to measure the ocular diopter. During the examination, the doctor will ask the patient to evaluate the degree of vision by observing the black letters or symbols on the myopic chart. Compare the letters or symbols seen by the patient with the standard vision chart to determine the patient's vision.
This method is based on the physiological characteristic that the human eye has different refractive responses to different colors of light. Through the different combination and quantity of red, green and blue light, the myopia table can simulate the situation of different diopter, so as to evaluate the patient's vision.
2. Corneal curvature measurement principle of myopia table
In addition to measuring the diopter, the myometer can also provide information about the curvature of the cornea. The cornea is the transparent front window of the eye, and its curvature has an important impact on the refraction of light. By observing the subtle structural changes on the myopic surface, doctors can indirectly assess the patient's corneal curvature.
This principle is based on the distortion of the symbols, letters and other structures on the myopia table when light is refracted. We know that when light passes through the cornea with different curvature, it will be refracted, and this refraction will cause the structural shape of the myopia surface to change. By observing these shape changes, doctors can conclude whether the patient's corneal curvature is normal.
3. Retinal imaging principle of myopia table
In addition to diopter and corneal curvature, the myopia table can also provide information about the patient's retinal imaging. This is also one of the important roles of myopia table in disease assessment.
The retina is a photosensitive tissue located inside the eyeball and has the function of recording images. The myopia table uses a special optical structure, which can feed back the patient's retinal imaging to the myopia table through the natural imaging process of the eye. By observing the retinal imaging on the myopia table, doctors can judge whether there is any abnormality in the patient's retina, and then carry out corresponding treatment.
4. Clinical application of myopia table
Based on the medical principle of myopia table, Shanghai Eye Hospital widely uses myopia table to assess the vision of myopia patients and monitor disease. Myometer can not only measure the patient's diopter and corneal curvature, but also provide retinal imaging to help doctors accurately judge the patient's eye health. According to the feedback information from the myopic chart, doctors can develop personalized treatment plans to provide better eye health management for patients.
In a word, the application of myopia table in Shanghai Eye Hospital is based on medical principles such as eye optics, corneal curvature and retinal imaging, which provides accurate vision assessment and disease monitoring means for myopia patients. Through the use of the myopia table, doctors can better understand the patient's eye health and develop personalized treatment plans. Shanghai Eye Hospital will continue to be committed to research and innovation in the field of eye health and provide more patients with high-quality ophthalmic medical services.
