Why can't oct see the fundus

OCT is a non-contact, non-invasive new optical diagnostic technology, mainly used in the diagnosis of fundus disease, especially helpful in the diagnosis of glaucoma and macular disease. Fundus disease is a common disease in ophthalmology, which has a high incidence, long duration, many types of diseases, complex etiology, and variable conditions, seriously affecting vision, causing great pain to patients over time, and resulting in a high rate of blindness. The emergence of ophthalmic OCT technology has a positive effect on the diagnosis and follow-up observation of fundus diseases and evaluation of treatment effects.

Traditional fundus examination often requires a lot of cumbersome steps, to the fundus fluorescence angiography, for example, need to go through a skin test to exclude the patient's allergic reaction to the injection of fluorescein can be carried out, not only a long time, but also to the patient to bring pain, the OCT examination technology to completely avoid the emergence of these shortcomings, which utilizes a certain wavelength of low-coherence light irradiation of the fundus imaging, non-invasive, only takes a few seconds, the OCT examination technology to avoid these disadvantages. The fundus vitreous interface, retina, macula, and other parts of the eye that are difficult to examine with general instruments can be clearly presented
