How does the Ophthalmology Department of Chengdu Huasha Eye Hospital check for eye diseases?
As an important organ for human to perceive the world, the eye is often threatened by various eye diseases. Eye hospitals, as institutions specialized in the treatment of eye diseases, often have advanced equipment and professional doctor teams, which can carry out accurate eye disease inspection. Here we take Chengdu Huasha Eye Hospital as an example to introduce how its ophthalmology department examines eye diseases.
1. Vision examination
Vision examination is one of the most common examinations in eye hospitals. The health of human retina and ocular diopter can be judged by visual inspection, and then various refractive errors and vision diseases can be diagnosed and treated.
First, doctors will use an eye chart to test the patient's nearsightedness, hyperopia or astigmatism. The vision chart is divided into two parts, one is the myopia part and the other is the hyperopia part. The patient needs to test the vision of the two parts respectively. The doctor will ask the patient to wear appropriate glasses or contact lenses and read the letters or symbols on the vision chart one by one to determine the clarity of vision.
Secondly, doctors will also use automatic anti Defoe instrument or excimer laser for corrective vision inspection. This inspection method does not require the use of glasses or contact lenses, which can more accurately measure vision and eliminate the possible errors caused by wearing glasses or contact lenses.
Finally, the doctor will perform binocular vision comparison and visual field examination. These examination items can determine whether the patient has monocular vision loss, color blindness, visual field defect and other diseases.
2. Fundus examination
Fundus examination is one of the important means of eye disease examination in ophthalmic hospitals. By observing the state of the fundus and retina, we can judge whether the patient has fundus diseases, retinal diseases and other diseases.
Commonly used instruments for fundus examination include: direct funduscopy, indirect funduscopy, empirical retinal fluorescein angiography, photocoagulation, etc. These instruments can magnify the fundus details, help doctors observe the blood vessels, nerve fiber layers, macular and other structures of the fundus and retina, and thus diagnose and treat patients' diseases.
Fundus examination requires the patient's eyes to relax and accept the doctor's guidance to complete the examination. During the examination, doctors will use fluorescent dye, laser and other auxiliary tools to observe the fundus conditions, so as to obtain accurate diagnostic results.
3. Intraocular pressure test
Intraocular pressure examination is one of the important methods to examine glaucoma in ophthalmic hospitals. Glaucoma is an eye disease caused by elevated intraocular pressure. If not treated in time, it will lead to optic nerve damage and visual loss.
Common intraocular pressure test methods include non-contact tonometer, electronic tonometer and opioid tonometer. These instruments can determine whether the patient has glaucoma or high intraocular pressure by measuring the intraocular pressure. When checking the intraocular pressure, the doctor will ask the patient to relax the lower eyelid, and use the instrument to gently touch the patient's cornea to measure the intraocular pressure.
4. Eye scanning
Eye scanning is an advanced ophthalmic examination method commonly used in ophthalmic hospitals at present. Stereoscopic scanning of eye tissues with high-definition scanning instruments can more intuitively observe and diagnose eye diseases.
The commonly used instruments for eye scanning include OCT (optical coherence tomography) and B ultrasound. Through OCT scanning instrument, doctors can visually observe the changes of various structures of the eye, and assist in diagnosing macular degeneration, vitreous hemorrhage and other diseases. Through the B ultrasound instrument, doctors can more comprehensively observe the internal conditions of the eyeball and diagnose diseases such as eyeball tumor and eyeball inflammation.
To sum up, Chengdu Huasha Eye Hospital has advanced instruments and a professional team of doctors in ophthalmic examination. It can accurately diagnose and treat various eye diseases and provide high-quality ophthalmic medical services for patients through vision examination, fundus examination, intraocular pressure examination, eye scanning and other methods.
