What Is an OCT (Optical Coherence Tomography) Scan, and How Does It Detect Eye Diseases? - #14522
I recently visited an eye doctor, and they recommended an OCT scan to check for possible vision issues. I want to understand what an OCT scan is, how it works, and whether it is necessary for everyone. Some people say that OCT scans are only for serious eye diseases, but I am unsure whether they can also detect early signs of vision problems. An Optical Coherence Tomography (OCT) scan is a non-invasive imaging test that provides high-resolution cross-sectional images of the retina and optic nerve. It helps in diagnosing glaucoma, macular degeneration, and diabetic retinopathy. Many ophthalmologists recommend OCT scans for people with high eye pressure or a family history of eye disease, but some people worry about costs and whether it’s necessary for routine checkups. However, I want to know whether lifestyle factors like diet, hydration, or blue light exposure affect eye health more than screenings. For those who have had an OCT scan, what conditions were detected, and was the test useful in early diagnosis? Would love insights into when an OCT scan is necessary and whether it can prevent vision loss.
