Macular degeneration is not difficult to diagnose. It can be detected and diagnosed through dilated fundoscopy, OCT, imaging, and so on. In general, when you go to the ophthalmology department, you need to do routine examinations, such as visual acuity, intraocular pressure, slit lamp, funduscopic examination, but for this kind of macular degeneration, there are two examinations that are very important, the first one is called Optical Tomography, referred to as OCT, and the second one is called fundus angiography. In most cases, experienced ophthalmologists can basically make a judgment through the ophthalmoscope, but still cannot completely confirm the diagnosis, and cannot understand the details of the disease. OCT is a non-invasive fundus scanning test that provides a very detailed tomographic scan of the macula, providing information on the location of the lesion, the extent of the lesion, and the progression of the disease. In simple terms, it reveals where in the fundus bleeding is leaking and how much fluid is present. Modern OCT examinations also have the function of navigational recognition, and the results of previous examinations of the same area can be compared, making it easier for the doctor to understand the effect of the medication used. When macular disease is suspected, it is advisable for patients to have this test done if available. OCT can basically confirm the diagnosis. At present, most hospitals are equipped with this equipment and can basically do this test. However, the results of different hospitals will have some differences, on the one hand, because there are various types of OCT equipment, some with higher resolution, providing more detailed information, and some with lower resolution, providing more fuzzy information; on the other hand, it also has to do with the operating techniques of the examiners. If the quality of the acquired image is not good, it will affect the doctor’s judgment of the result; if the most important lesion areas are not swept, it will also affect the diagnosis, and the prediction of the treatment result. If the patient has cataracts, vitreous clouding, and some corneal diseases, it may also affect the results of the OCT scan. The cost of the test is not quite the same in each hospital, Qilu Hospital OCT examination of one eye 170 yuan, both eyes 340 yuan, usually do not need to make an appointment in advance, the same day done to get the results. The OCT scan can understand the structure of the lesion in the fundus, but it cannot understand the status of the blood vessels. With a fundus angiogram, the doctor is able to see where the neovascularization is growing, how extensive it is, and whether it is now active or receding. These are two complementary tests that are not interchangeable. It is a very necessary test for the diagnosis of fundus diseases, including macular diseases, and is highly recommended, especially when the diagnosis is made for the first time. Elderly people are older, there is a certain risk to do this test, so before doing the test, the doctor will ask the patient whether there is any heart disease, cerebrovascular lesions in the past, as well as blood pressure, and it is necessary to control the underlying diseases well before the test; fundus imaging test must be done before the allergy test, the patients who are allergic to the contrast agent can not carry out this test. Before the examination, diluted contrast medium is injected into the patient’s vein, and after 5 minutes, the patient is observed to have any obvious allergic reactions such as rash, edema or dyspnea. In most cases, patients are now able to complete this test. The ophthalmology departments in general hospitals are able to do this test, and as in the case of OCT, the images are clearer in some hospitals and blurrier in others. This test requires a better operator to obtain high quality images. If the images from the test are clear and the time of the test is close to the time of this visit, we can adopt the images done at the local hospital.
