How to interpret the optometry results of Shanghai Eye Hospital?

Eye hospitals are specialized in providing diagnosis and treatment services for eye diseases, and optometry results are one of the important bases for ophthalmologists to judge patients' eye health. This article will elaborate on how to interpret the optometry results of Shanghai Eye Hospital from four aspects.

Radius of curvature of cornea

Corneal radius of curvature is the result of measuring the curvature of the anterior surface of the cornea of the patient's eyes with a refractometer. The larger the radius of curvature of the cornea, the steeper the curvature of the cornea; On the contrary, the smaller the radius of curvature of the cornea, the flatter the curvature of the cornea. The result of the radius of curvature of the cornea can help doctors understand whether patients have eye diseases such as myopia, hyperopia or astigmatism. If the radius of curvature of the cornea is within the normal range, it usually indicates that the patient's eye health is good.

In the optometry results, if the radius of curvature of the cornea is abnormal, it may indicate that the patient has ametropia, which needs further analysis and treatment by the doctor.

Visual examination

Vision examination is an essential part of optometry. By providing patients with an eye chart, doctors can assess the ability of patients' eyes to recognize distant and near objects. The results of vision examination are expressed by scores, such as 20/20. The numerator represents the patient's vision, and the denominator represents the normal person's vision of the same object. The patients whose vision examination results are 1.0 or 20/20 represent normal vision; The patients whose vision is lower than 1.0 or 20/20 mean that their vision is impaired to some extent.

The result of visual examination is an important basis for judging whether patients need to wear glasses or contact lenses. If the result of vision examination is not ideal, it may mean that the patient has myopia, hyperopia, astigmatism and other common eye diseases.

Diopter measurement

The diopter measurement is the result of measuring the patient's ocular diopter with a refractometer. By judging the focusing ability of the patient's eye, the ophthalmologist can determine whether the patient suffers from refractive errors, such as myopia, hyperopia, astigmatism, etc.

The result of diopter measurement is usually expressed as "D", with positive number representing hyperopia and negative number representing myopia. The size of the diopter measurement results represents the intensity of the patient's need to correct vision, so as to help doctors determine whether to wear glasses or carry out other treatments.

Fundus examination

Fundus examination is to observe the bottom of the patient's eyeball through a magnifying glass and other tools. The results of fundus examination can help doctors understand the condition of the patient's retina, macula, optic nerve and other important structures, so as to judge whether the patient has eye diseases, such as macular degeneration, glaucoma, etc.

In fundus examination results, if macular or retinal lesions are found, further treatment or surgical intervention may be required. The normal fundus examination results show that the patient's eye structure is normal, reducing the risk of eye disease.

Summary

Through the interpretation of optometry results in Shanghai Eye Hospital, we can draw the following conclusions: First, the results of corneal radius of curvature can help doctors judge whether patients have refractive errors; Secondly, the vision examination results can evaluate whether the patient's vision is normal, so as to determine whether glasses are needed; In addition, the results of diopter measurement can help doctors determine whether patients have myopia, hyperopia and other problems; *Later, the results of fundus examination can help doctors understand whether the patient's eye structure is normal and judge whether there is eye disease.

In a word, the optometry results of Shanghai Eye Hospital are an important basis for ophthalmologists to judge patients' eye health. Through the interpretation of the results of corneal curvature radius, vision examination, diopter measurement and fundus examination, doctors can comprehensively assess the patient's eye conditions and determine the appropriate treatment plan. I hope this article can provide a reference for readers to interpret the optometry results of Shanghai Eye Hospital.
