Guangzhou Zhongshan Affiliated Ophthalmic Clinic Ophthalmic Examination Project
As a professional ophthalmic hospital, Guangzhou Zhongshan Affiliated Ophthalmic Clinic provides a variety of ophthalmic examination items to help patients understand and treat eye problems in a timely manner. The following will introduce the examination items of the ophthalmic clinic in detail from four aspects: corneal examination, visual examination, fundus examination and intraocular pressure examination.
1、 Corneal examination
Cornea is one of the common objects in ophthalmic clinic. Corneal examination is designed to assess the health of the cornea and the presence of disease. Common corneal examination items include:
1. Corneal curvature measurement: by measuring the curvature of the front surface of the cornea, evaluate its ability to refract light and judge whether there is any refractive abnormality.
2. Corneal topographic map: With the help of computer system, the topographic map of the corneal surface is drawn, and the curvature, height and shape of the cornea are measured and analyzed to help diagnose and treat refractive errors, corneal diseases and other problems.
3. Anterior segment scanning: optical imaging technology is used to observe and measure the anterior segment structure of the cornea, including anterior chamber depth, corneal thickness, etc., which has auxiliary diagnostic value for glaucoma, dry eye and other diseases.
2、 Visual examination
Another important examination item of the ophthalmic outpatient service is the vision examination. By measuring the patient's vision level, we can understand the basic function of their eyes. Vision examination includes the following aspects:
1. Corrected vision measurement: after using glasses or contact lenses for correction, measure the patient's vision and assess visual clarity.
2. Astigmatism inspection: test whether the patient has astigmatism problems, to determine whether to wear special astigmatism glasses.
3. Color blindness inspection: check whether there is color blindness or color weakness by letting patients identify patterns or numbers of various colors.
3、 Fundus examination
Fundus examination is to observe and evaluate the internal structure of the eye, and check whether there are fundus diseases or other potential problems by observing the fundus blood vessels, optic disc, retina and other parts. Common methods of fundus examination include:
1. Direct funduscopy: doctors use special funduscopy to directly observe fundus structure, and clearly observe and evaluate fundus blood vessels, optic disc, retina and other parts through magnifying lenses.
2. Indirect funduscopy: doctors use indirect funduscopy to observe the fundus. By adjusting the light source and lens, they can observe a wider funduscopy area, which is especially suitable for observing areas around the retina and macula.
3. Fluorescein fundus angiography: by giving patients intravenous injection of fluorescein dye, observe and record fluorescein angiography images to help diagnose and treat fundus diseases.
4、 Intraocular pressure test
Intraocular pressure refers to the fluid pressure inside the eyeball. Detection of intraocular pressure can assess the risk of glaucoma and help identify relevant eye problems early. Common methods of intraocular pressure examination in ophthalmic clinics include:
1. Non contact intraocular pressure measurement: without contacting the eyeball, use air or light source and other technologies to measure the intraocular pressure level, and quickly and accurately assess the intraocular pressure.
2. Four manual intraocular pressure measurement: the doctor measures the intraocular pressure level by placing a pressure measuring device on the cornea. This method requires doctors to operate and contact patients' eyeballs, and is generally used for more accurate intraocular pressure measurement.
3. 24-hour intraocular pressure measurement: by wearing a special intraocular pressure measurement instrument, monitoring the changes of intraocular pressure for 24 hours continuously, it is very helpful to evaluate the stability and effect feedback of glaucoma.
summary
Guangzhou Zhongshan Affiliated Ophthalmic Clinic provides a variety of ophthalmic examinations, including corneal examination, visual examination, fundus examination and intraocular pressure examination. These projects can help doctors understand patients' eye problems in a timely manner and provide targeted treatment plans. Through regular ophthalmic examinations, we can find early signs of eye problems, prevent and treat the development of eye diseases, and protect vision health.
