How is Xi'an Ophthalmology OCT performed?
Fundus diseases are one of the common diseases in ophthalmology. In order to more accurately diagnose and treat fundus diseases, ophthalmologists often use optical coherence tomography (OCT) technology for examination. Next, we will introduce the process of Xi'an Ophthalmology OCT examination in detail from four aspects: equipment preparation, examination steps, examination results and relevant precautions.
Equipment preparation
Before OCT examination, doctors and patients need to make corresponding preparations. First of all, the doctor needs to check the working status of the OCT equipment to ensure that the equipment operates normally. At the same time, doctors also need to confirm whether patients have contraindications, such as photosensitivity or near infrared photosensitivity. For patients, it is necessary to make an appointment in advance and inform the doctor of relevant medical history, such as eye surgery history, disease history, etc., when reporting to the hospital, so that the doctor can better evaluate the eye condition.
At the same time, the patient needs to make some simple preparations for the eyes. First, glasses or contact lenses need to be removed to avoid affecting the inspection results. Secondly, patients need to thoroughly clean their eyes to prevent dust or dirt from interfering with the examination.
Inspection steps
After the equipment is prepared, the ophthalmologist will perform OCT examination for the patient. The specific steps are as follows:
1. The patient needs to sit on the inspection seat, place his chin on the corresponding bracket, and tilt his head slightly forward to keep his eyes stable.
2. The doctor will put a pair of glasses on the patient to make the patient's eyes aim at the inspection beam and maintain the clarity of the retina.
3. The doctor will tell the patient to look at a specific position to maintain a stable vision.
4. Next, doctors will use OCT equipment to scan. During scanning, the patient may feel some slight tingling or foreign body sensation, but it will not cause any damage to the eyes.
5. After the examination, the doctor will tell the patient to relax his eyes and have a rest.
Inspection results
After OCT examination, the doctor will analyze and diagnose according to the examination results. The results of OCT generally include images and numerical data of fundus structure.
Fundus structure image is one of the main results of OCT, which can show the retina, vitreous, choroid and other eye structures. Through these images, doctors can judge whether there are fundus diseases, such as macular edema, retinal pigment epithelial diseases, etc.
Numerical data are derived from OCT, such as foveal thickness, macular edema degree, etc. These data can provide more objective indicators to assist doctors in disease assessment and treatment decisions.
matters needing attention
When receiving OCT examination, patients should pay attention to the following points:
1. When receiving OCT examination, patients need to keep their eyes stable and focus on specific positions to ensure the accuracy of the examination results.
2. The patient may feel some slight discomfort during the examination, such as tingling or foreign body feeling, but it will not cause damage to the eyes.
3. Some patients may need to receive fundus macular scanning. At this time, they need to specially cooperate with the doctor's guidance and should not rotate their eyes at will.
Through the detailed introduction of the above four aspects, we learned the whole process of Xi'an Ophthalmology OCT examination. Patients only need to make corresponding preparations and cooperate with doctors to complete the examination of fundus lesions quickly and accurately. OCT examination can not only provide ophthalmologists with detailed fundus structure information, but also help doctors to formulate treatment plans, improve the treatment effect, and better protect patients' vision health.
In a word, Xi'an Ophthalmic OCT is a very important ophthalmic examination technology, which plays an important role in assisting the diagnosis and treatment of fundus diseases.
