Diagnostic methods of ophthalmic keratitis in Xi'an
Ophthalmic keratitis refers to the inflammation of the cornea, which is often caused by bacterial, viral, fungal and other infections. For patients in Xi'an, the correct diagnosis method is very important, because it can help doctors to identify the cause of disease and choose the appropriate treatment scheme. The following will introduce the diagnosis methods of Xi'an ophthalmic keratitis from different aspects.
1. Analysis of medical history and symptoms
When seeing a doctor in Xi'an Eye Hospital, the doctor will first ask the patient's medical history in detail, including time of onset, cause of onset, treatment experience, etc. This information can help doctors understand the initial conditions of the disease and speculate on the possible causes.
Secondly, the doctor will carefully ask the patient about the symptoms of the eye, such as redness, eye pain, blurred vision, photophobia, tears and other symptoms. The symptoms of ophthalmic keratitis caused by different causes are slightly different. Through detailed symptom analysis, doctors can further narrow the scope of diagnosis.
*Later, doctors also need to know the general health status of patients, recent exposure to infection sources and drug use for comprehensive analysis and judgment.
2. Physical inspection
Physical examination is an important means to diagnose ophthalmic keratitis, including eye measurement, anterior segment examination, etc.
First, the doctor will perform a vision examination to assess the patient's vision. Vision decline is one of the common symptoms of ophthalmic keratitis, and the examination results can reflect the impact of inflammation on vision.
Secondly, doctors will use hand-held slit lamps or microscopes and other equipment to perform anterior examination on the eyes of patients, and observe the shape, transparency, ulcer, scar and other abnormalities of the cornea. These abnormal features can indicate the type of inflammation. For example, corneal ulcer, a common bacterial infection, can be preliminarily judged by anterior examination.
In addition, doctors can also check the condition of the patient's eyelids and conjunctiva to rule out the possible coexisting diseases of other patients, such as conjunctivitis and blepharitis.
3. Etiology inspection
In order to identify the pathogen and the specific cause of keratitis, etiological examination is necessary.
A commonly used method of pathogenic examination is eye swab sampling. The doctor will use the sterilized sampling cotton swab to gently wipe the patient's eye secretion or corneal ulcer surface, and send the obtained samples to the laboratory for cultivation and detection of bacteria, viruses, fungi and other pathogens.
In addition, doctors can also use protein detection, antibody detection or PCR and other methods to determine the cause of keratitis according to the changes of specific markers in patients' body fluids.
4. Other auxiliary inspection
If the initial medical history, symptom analysis and physical examination cannot make a clear diagnosis, the doctor can also carry out other auxiliary examinations to help determine the diagnosis.
For example, a doctor may choose to have a corneal dye test. Under the color development of the dye, the inflamed part of the patient's cornea will appear green or yellowish green, which is helpful to confirm the inflamed part and scope.
In addition, ophthalmologists can also use fundus imaging, ocular ultrasound and other imaging technologies to help diagnose and determine the cause of disease by observing changes in the structure of the eye.
Summary
The diagnostic methods of Xi'an ophthalmic keratitis include history and symptom analysis, physical examination, etiology examination and other auxiliary examinations. Through the comprehensive application of these methods, doctors can accurately determine the cause and type of keratitis, and then formulate a reasonable treatment plan. Therefore, the patient should cooperate with the doctor's inquiry and inspection, and provide detailed and accurate information to help the doctor quickly and accurately diagnose.
