Steps of ophthalmic examination
Ophthalmic examination refers to the process of comprehensive examination and evaluation of patients' eyes through the use of various instruments and technical means. The main purpose of ophthalmic examination is to determine the patient's eye health, and to find and diagnose eye diseases. Here are some common ophthalmic examination procedures:
1. Vision examination:
Vision examination is the basic item in ophthalmic examination, and also the most common one. The doctor will ask the patient to cover one eye, then let the patient see some letters or charts clearly from different distances, and assess their vision according to the smallest font size that the patient can distinguish. This process will test the patient's far vision and near vision respectively.
In vision examination, doctors usually use projection method, electronic screen or glasses and other tools to check. Through visual inspection, doctors can initially understand the patient's visual ability and whether there are refractive errors and other problems.
2. Intraocular pressure test:
Intraocular pressure test is a method to detect intraocular pressure, which aims to screen and diagnose glaucoma and other eye diseases. Doctors usually use a device called non-contact manometer. During the examination, patients only need to look forward to a light, and the instrument can automatically measure intraocular pressure.
The principle of intraocular pressure inspection is to send air pressure to the eye through the instrument, and then test the rebound of the eye, and then obtain the value of intraocular pressure. The normal intraocular pressure range is 10-21 mmHg. If the intraocular pressure is too high, it may be one of the pathological manifestations of glaucoma, which needs further examination and diagnosis.
3. Fundus examination:
Fundus examination is an examination method to evaluate the health of the eye by observing the fundus and optic nerve. Usually, doctors will use an instrument called eyeground mirror, with appropriate light source, to observe the details of the fundus through the pupil of the patient.
Fundus examination can see the shape and color of various structures inside the eye, including retina, macula, optic disc, etc. Through fundus examination, doctors can determine whether there are macular disease, retinal vascular abnormalities, edema of the optic disc and other diseases.
4. Optometry:
Optometry is mainly to assess the patient's refraction and the degree to be corrected by wearing lenses of different degrees or adjusting their positions. The doctor will gradually adjust the lens according to the patient's response and visual needs until the best visual clarity is found.
Optometry can help patients choose appropriate glasses or contact lenses, correct refractive errors and other problems, and improve vision and visual comfort.
Procedures of ophthalmic examination in Guangzhou
Guangzhou is a first tier city in China, with many top eye hospitals and eye clinics. The steps of ophthalmic examination in Guangzhou are as follows:
1. Appointment and registration: Before going to Guangzhou Eye Hospital, patients need to make an appointment to confirm the time and place of the examination. After arriving at the hospital, the patient needs to register at the front desk and fill in personal information and medical records.
2. Identity verification and medical record review: In order to ensure the patient's identity information, the hospital will conduct identity verification and review the patient's medical record. At the same time, patients also need to provide some necessary certificates and information.
3. Ophthalmic examination items: according to the specific situation of the patient and the doctor's suggestions, there will be different ophthalmic examination items. These items include vision examination, fundus examination, intraocular pressure examination, optometry, etc. Other special examinations may be carried out according to the specific conditions, such as corneal topography, eye position examination, etc.
4. Doctor's diagnosis and treatment suggestions: the doctor will make diagnosis and give corresponding treatment suggestions according to the examination results and the patient's symptoms and medical history. The doctor will explain the condition to the patient, answer the patient's questions, and develop a treatment plan and follow-up plan.
5. Settlement and departure: after the examination, the patient needs to go to the hospital's charging window for settlement and get the relevant examination results and medical orders. If necessary, the patient can also make an appointment for the next visit or follow-up.
summary
Ophthalmic examination is an important means to assess eye health and find eye diseases. Common ophthalmic examination procedures include vision examination, intraocular pressure examination, fundus examination and optometry. The ophthalmic examination procedures in Guangzhou generally include appointment and registration, identity verification and medical record review, ophthalmic examination items, doctor's diagnosis and treatment suggestions, settlement and hospital departure.
