SD-OCT

Meaning

SD-OCT, or Spectral-Domain Optical Coherence Tomography, is a high-speed, non-invasive imaging technology routinely used in ophthalmology to capture cross-sectional, micron-level resolution images of the retina and the optic nerve head. This advanced diagnostic tool functions analogously to an optical ultrasound, providing incredibly detailed visualization of the various retinal layers, including the fovea and the retinal pigment epithelium. Clinically, SD-OCT is indispensable for accurately diagnosing, precisely monitoring, and objectively quantifying subtle structural changes, such as thinning or fluid accumulation, often associated with drug-induced maculopathy or other complex retinal diseases.
