Xi'an Eye Vision Examination Project

Vision is an important indicator of eye health, and vision examination is a common ophthalmic examination item. In Xi'an Eye Hospital, vision examination involves many aspects to ensure that patients' vision problems are comprehensively evaluated and treated. The following will elaborate the vision examination items of Xi'an Ophthalmology Department from four aspects: refractive examination, intraocular pressure measurement, visual field examination and ophthalmic bottom examination.

Refractometry

Refractive examination is an important part of vision examination, which is used to assess the diopter and refractive state of the eye and help doctors determine whether there are refractive problems such as myopia, hyperopia, astigmatism, etc. Xi'an Ophthalmic Hospital usually uses automatic optometry or computer optometry for refractive examination.

In refractive examination, the patient needs to observe the letters or symbols prompted by the doctor one by one, and respond to the doctor according to the size and clarity of the sequence. The doctor will record the size of the letters that the patient can clearly see to determine the accuracy of their vision and obtain accurate refractive index values.

Through refractive examination, doctors can judge whether patients need to wear glasses or contact lenses, and provide * excellent refractive correction scheme.

Intraocular pressure measurement

Intraocular pressure measurement is one of the key indicators for evaluating eye health, especially for early detection and treatment of glaucoma. In Xi'an Eye Hospital, intraocular pressure is usually measured with non-contact or contact pressure measuring instruments.

The non-contact pressure measuring instrument usually uses the gas sensing principle to calculate the intraocular pressure by aligning a beam of air flow with the corneal surface and measuring the change of air flow after being reflected by the cornea. The contact manometer measures the intraocular pressure by first dropping a drop of anesthetic eyedrops on the cornea, and then measuring the intraocular pressure with an instrument called "ophthalmoscope".

Intraocular pressure measurement is of great significance for early detection of glaucoma and other eye diseases. Timely treatment can avoid further impairment of vision.

Perimetry

Perimetry is used to evaluate the central and peripheral visual range of the patient, and detect whether the patient has visual field defects and other problems. In Xi'an Eye Hospital, visual field examination is usually performed with computerized automatic perimetry or hand-held perimetry.

In perimetry, the patient needs to look at the screen or target and respond to the doctor when the test prompt appears. During the test, the light spot or pattern will appear on the screen. The patient should try to focus on the center, and press the button or answer questions when noticing the light spot or pattern. The doctor will record the visual field defect according to the patient's response.

Visual field examination can be used to detect and monitor glaucoma, optic neuritis and other diseases early, and assess the degree of visual impairment of patients.

Ophthalmic bottom examination

Ophthalmic fundus examination is an important means of examining fundus structure, which can observe the pathological changes of optic nerve, retina and blood vessels. In Xi'an Eye Hospital, fundus camera or ophthalmoscope is usually used for fundus examination.

Eye examination at the bottom needs to expand the pupils so that doctors can observe the fundus more clearly. The doctor will put a drop of mydriasis eyedrops on the patient's eyes, wait for a period of time, and then use a camera or mirror to observe the fundus structure. Through the bottom examination of ophthalmology, doctors can find eye diseases such as retinal detachment, vitreous hemorrhage, and macular disease.

Ophthalmic fundus examination is a very important part of vision examination, which can help doctors diagnose and treat fundus diseases.

Summary

Through the detailed description of the vision examination items in Xi'an Eye Department, we can learn that the vision examination in this hospital mainly includes refraction examination, intraocular pressure measurement, visual field examination and ophthalmic bottom examination. These projects can comprehensively assess the vision health of patients, timely discover and treat eye diseases, and provide * good vision correction programs. Vision examination is of great significance for the assessment and treatment of eye health. It is recommended that we conduct vision examination regularly to protect eye health.
