The Role of OCT in Fundus Examination and Treatment
Sep 14 , 2022
In clinical practice, choroidal rupture caused by indirect external force is common. Blunt trauma can cause rapid deformation of the eyeball, leading to anterior and posterior compression and horizontal expansion of the eyeball. Collagen rich sclera and flexible retinal tissue rarely rupture, while bullet free RPE, Bruce membrane and choroidal capillaries are easy to rupture. The incidence of chor...

History of OCT in Ophthalmology
Oct 09 , 2022
In 1991, Huang et al. of the Massachusetts Institute of Technology first used the developed OCT to observe the isolated human retina and optic disc. in 1995,it was officially used in ophthalmology. The initial clinical application of OCT is OCT1, with only 10 scanning procedures and 7 analysis procedures. In 1997, the OCT2 scanning procedure was increased by 2 and the analysis procedure was ...

Hidden Visual Killer - Sugar Net
Jan 28 , 2023
Diabetes is not diabetes caused by eating too much sugar. It occurs when the pancreas is no longer able to make insulin, or when the body cannot make good use of the insulin it produces. Sustained high blood sugar can cause serious diseases affecting the heart and blood vessels, eyes, kidneys, nerves and teeth. In addition, people with diabetes are at higher risk of developing infections. Diabetes...

What are the working principles and characteristics of Optical Coherence Tomography？
Jan 03 , 2025
Angio OCT (Optical Coherence Tomography) is a non-invasive imaging technique used to observe the vascular structure and blood flow dynamics of the retina and choroid at high resolution. It combines the cross-sectional imaging capabilities of optical coherence tomography (OCT) with blood flow analysis and is widely used in the field of ophthalmology. Working principle The core technology of Angio O...

What causes retinal detachment?
Mar 13 , 2025
Retinal Detachment (RD) refers to the separation of retinal nerve epithelia from pigment epithelia, resulting in the inability of photoreceptor cells to properly receive and conduct light signals, which can lead to irreversible visual impairment or even blindness in severe cases. RD can be divided into three categories: porosity, tractive and exudative. Among them, rheogenic retinal detachment is ...
