Northwest Vision Center, a local Columbus eye care practice with a proud reputation for client satisfaction and care, proudly introduces the addition of Optical Coherence Tomography (OCT), the latest cutting-edge technology for the earliest detection and treatment of common eye conditions such as glaucoma, macular degeneration and diabetic retinopathy. OCT is a non-invasive imaging test that uses light waves to obtain cross-section pictures of the light-sensitive tissue lining the back of the eye, known as the retina.
