How to check eye disease

Fundus diseases are generally examined by ophthalmoscopy, optical coherence tomography, fundus fluorescence angiography, etc. These examination methods can help doctors observe the structure and function of the fundus, thus diagnosing fundus diseases.

1. Ophthalmoscope

is a commonly used instrument for examining fundus diseases. Through ophthalmoscope, doctors can directly observe the changes in the structure of retina, optic nerve papilla, retinal blood vessels, etc., so as to determine whether there is fundus

disease.2. Optical coherence tomography This

is a non-invasive examination method that uses optical principles to perform high-resolution tomographic imaging of the fundus. Through optical coherence tomography, doctors can more clearly observe the changes in the structure of each layer of the fundus, which is helpful to find early lesions of fundus

disease.3. fundus fluorescence angiography

This is a special examination method, by injecting fluorescein into the patient's vein, and then using a special fundus camera to photograph the process of fluorescein filling in the fundus vessels. Through fundus fluorescence angiography, doctors can observe the morphological and functional changes of fundus vessels, which is helpful to diagnose fundus vascular diseases.
