An Optical Coherence Tomography scan (commonly referred to as an OCT scan) is the latest advancement in imaging technology. Similar to ultrasound, this diagnostic technique employs light rather than sound waves to achieve higher resolution pictures of the structural layers of the back of the eye.
A scanning laser is used to analyze the layers of the retina and optic nerve for any signs of eye disease, similar to a CT scan of the eye. It works using light without radiation and is essential for the early diagnosis of glaucoma, macular degeneration, and diabetic retinal disease.
With an OCT scan, doctors are provided with color-coded, cross-sectional images of the retina. These detailed images are revolutionizing the early detection and treatment of eye conditions such as wet and dry age-related macular degeneration, glaucoma, retinal detachment and diabetic retinopathy.
An OCT scan is necessary if we are managing a patient for diseases such as diabetes, glaucoma, and macular degeneration. They are also great for detecting problems that would not have been otherwise found with other eye exams.
An OCT scan is a non-invasive, painless test. It is performed in about 10 minutes right in our San Jose office. Feel free to contact our Buena Vista Eyecare Optometry office to inquire about an OCT at your next appointment.
