Examination of ophthalmic tumors in Xi'an
Eye tumor refers to the tumor in the eye tissue. Its early symptoms are not obvious and it is easy to be ignored. For the eye tumor examination in Xi'an Ophthalmology Department, the following examinations are generally required.
1. Eye examination
Eye examination is one of the important methods to diagnose eye tumors. The doctor will use a microscope to examine the subject's eyeball. This examination method is simple and reliable. The size, color, shape and other characteristics of the eye tumor can be observed to determine whether it is a tumor.
In addition, doctors will also perform eye movement tests to understand whether the tumor has affected the patient's eye movement function and vision. Abnormal eye movement and decreased vision may be one of the symptoms of eye tumors.
In the eye examination, the doctor will also combine the fundus examination to further judge the type and severity of eye tumors by observing the changes of fundus blood vessels, optic disc, retina and other tissues.
2. Eye ultrasonic examination
Ocular ultrasound is a non-invasive, painless and radiation free examination method, which can comprehensively evaluate the intraocular structure. For the detection of eye tumors, ophthalmic ultrasound can help doctors determine the size, location, shape and other information of tumors.
There are two types of ophthalmic ultrasonography: A type and B type. Type A ophthalmic ultrasound can observe the structure of the eyeball through sound waves, and can observe the shape, location, size and other information of intraocular tumors. B-mode ocular ultrasound can generate three-dimensional images of the eyeball, which can more clearly observe the details of the eyeball tissue.
Ocular ultrasound is of great value in screening and diagnosing various ocular tumors, and can help doctors determine whether further treatment is needed.
3. Fundus fluorescein angiography
Fundus fluorescein angiography is an inspection method that is observed by injecting dye. It can help doctors observe the changes of fundus blood vessels and is helpful for the detection of eye tumors.
During the examination, the doctor will collect a certain amount of dye on the patient's arm, and then inject it into the patient's body through vein. With the spread of dyes, doctors use professional equipment to observe the changes of eyeground blood vessels and further judge the type and distribution of eye tumors.
4. Eye biopsy
Eye biopsy is a method of directly obtaining eye tissue samples for examination, which can help doctors make a clear diagnosis. For uncertain ocular tumors, ocular biopsy is an important diagnostic method.
In this examination, the doctor will use a special tool to obtain a small part of tissue samples from the patient's eyeball according to the location and size of the tumor. Then send the sample to the laboratory for cytological or histological examination, and judge the tumor type by observing the morphology and structure of the tissue cells.
summary
Xi'an Ophthalmology Department's examination of eye tumors mainly includes eye examination, eye ultrasound, fundus fluorescein angiography and eye biopsy. These examination methods can help doctors determine the type, location, distribution and severity of eye tumors, and provide accurate diagnosis and treatment for patients.
