What Is OCT (Optical Coherence Tomography), and How Is It Used in Eye Diagnosis? - #14440
I recently went for an eye check-up, and my doctor suggested an OCT (Optical Coherence Tomography) scan to examine my retina and optic nerve. I want to understand how this test works, what conditions it detects, and whether it is necessary for routine eye care. Some people say that OCT scans are mainly used for detecting retinal diseases, but I am unsure whether they are also helpful for other vision problems. OCT is a non-invasive imaging test that provides high-resolution cross-sectional images of the retina, optic nerve, and macula. It is commonly used to diagnose conditions such as glaucoma, diabetic retinopathy, age-related macular degeneration (AMD), and retinal detachment. Many eye specialists recommend this scan for individuals with diabetes, vision changes, or a family history of eye diseases. However, I want to know whether it is necessary for people with no symptoms or if it is only for those already experiencing vision problems. For those who have undergone an OCT scan, what results did it reveal? Did it help in early detection of eye diseases, and how often should this scan be done? Would love insights into how useful OCT scans are for eye health and whether they should be part of routine check-ups.
