Ocular imaging generally refers to fundus angiography, which is used to examine the condition of the blood vessels in the fundus to determine the presence of eye disease.
Fundus angiography is one of the most common tests performed in ophthalmology. Through this examination, the condition of the capillaries in the fundus, such as retinal blood vessels and choroidal blood vessels, can be observed, so as to diagnose macular degeneration, retinal hemangioma, retinal artery and vein obstruction, diabetic retinopathy, etc., and to help observe the effect of treatment of ocular diseases in the clinic.
Since the examination requires the injection of contrast medium, fundus angiography is contraindicated for those who are allergic to contrast medium. It is also contraindicated for people with glaucoma and serious organic diseases of the heart, liver and kidneys to prevent aggravation of the condition. If the examination process is accompanied by uncomfortable symptoms, such as nausea and vomiting, dizziness, etc., should promptly inform the doctor for treatment.
In order to ensure the accuracy of the test results, it is recommended to consult a regular hospital for fundus angiography. For those with abnormal test results, it is necessary to further combine with other examination programs to clearly diagnose the disease, so as to treat the disease as soon as possible.
