Optical Coherence Tomography (OCT) Explained | Glaucoma Diagnosis and Monitoring

In this video, we explain Optical Coherence Tomography (OCT), a non-invasive imaging test used to evaluate the optic nerve and retina in patients with glaucoma. Learn how OCT measures the retinal nerve fiber layer (RNFL), ganglion cell layer, and optic nerve head, helping clinicians detect glaucoma early and monitor disease progression over time. 👉 OCT provides structural information that complements visual field testing in glaucoma assessment.
