What items does Guangzhou eye examination include?
Guangzhou is an important economic and cultural center in southern China, with many first-class hospitals and ophthalmology specialties. Ophthalmic examination is an indispensable part of daily eye health management. Next, we will introduce the ophthalmic examination items in Guangzhou from four aspects.
Visual examination
Vision examination is the basic step of ophthalmic examination. Eye hospitals in Guangzhou usually use standard visual acuity charts, such as Snellen's visual acuity chart, to assess patients' vision. By observing the distance and size of the letters, the doctor can determine the naked vision and corrected vision of the patient. This examination item is very important for finding problems such as ametropia and amblyopia.
In addition to naked vision and corrected vision, ophthalmologists can also use other test methods, such as contrast sensitivity test, dark adaptation test and visual field test. These additional tests can further assess the patient's visual function and help the doctor determine whether there are other eye problems.
Intraocular pressure measurement and fundus examination
Intraocular pressure measurement and fundus examination are common items in ophthalmic examination, which can help doctors find eye diseases such as glaucoma. In intraocular pressure measurement, doctors will use special instruments, such as the Application tonometer, to assess the fluid circulation in the eyeball by measuring intraocular pressure. Fundus examination is to evaluate the fundus condition of patients by observing fundus blood vessels and optic nerve head.
In the eye hospitals in Guangzhou, intraocular pressure measurement is usually painless, and fundus examination may need to increase the diameter of the eye pupil, so that doctors can better observe fundus details. Ophthalmologists can use special eyedrops to dilate the pupils, which may cause some temporary blurred vision. Therefore, before receiving these examinations, patients need to know the relevant precautions in advance.
Corneal topography and tear examination
Corneal topography and tear examination are mainly used to evaluate the problems of eye surface. Corneal topography can be used to detect corneal irregularities, corneal deformation and other problems. Ophthalmologists in Guangzhou usually use corneal topography instruments, such as corneal apex scanners, to generate corneal topography by measuring the curvature and thickness of the cornea.
Tear examination can evaluate the secretion and quality of tears, which is helpful to diagnose dry eye and other tear related problems. In Guangzhou eye hospitals, Schirmer test and tear evaporation rate measurement are usually used for tear examination.
Eye disease screening and laser treatment
The ophthalmic examination in Guangzhou also includes screening of eye diseases and laser treatment. Ophthalmologists will assess whether patients have eye diseases, such as glaucoma, cataract, eyelid diseases, etc. through detailed medical history inquiry and eye examination. Once confirmed, doctors may recommend laser therapy and other means of treatment.
Laser therapy is a common ophthalmic surgery method, which can be used to treat myopia, hyperopia, astigmatism and other refractive errors. Eye hospitals in Guangzhou are usually equipped with modern laser surgical equipment, such as excimer laser, LASIK, etc. Patients can choose their own laser treatment methods under the guidance of doctors.
summary
Guangzhou ophthalmic examination includes many items, including vision examination, intraocular pressure measurement and fundus examination, corneal topography and tear examination, as well as eye disease screening and laser treatment. These programs are designed to help people maintain eye health, identify and treat eye problems in a timely manner. If necessary, it is recommended to go to a regular eye hospital for examination and treatment.
