Oct Optical Coherence Tomography
What is OCT?
The OCT (optical coherence tomography) It allows the anatomy of the retina to be reconstructed in the macular region. un non-invasive test and provides images high-resolution slice scans (tomographic) of the cornea, of the central part of the retina (macula) and the head of the optic nerve (papilla). Computerized tissue analysis allows for the reconstruction of the structure in two-dimensional planes and three-dimensional volumes. The operating principle of interferometry is similar to that of ultrasound, using the reflection of a harmless laser beam instead of acoustic waves.
What is the purpose of the exam?

OCT is indicated in patients in whom a disease of the cornea, retina and optic nerveOCT provides information on structural changes in the retina, precisely identifying their location. It also allows for the automated measurement of tissue thickness (useful for monitoring the progression of diseases over time) and the cornea, analyzing structural changes and identifying the depth of lesions. Optical coherence tomography is indispensable for the diagnosis, monitoring, and clinical decision-making regarding the treatment of many important retinal diseases, such as:
- Age-related macular degeneration and youthful
- Serous and hemorrhagic detachment of the retinal neuroepithelium and pigment epithelium
- Intraretinal and preretinal neovascularization
- Diabetic retinopathy
- Retinal vein occlusion
- Acute and chronic chorioretinopathies
- Macular edema
- Retinal atrophy
- Macular hole and pseudohole
- Vitreoretinal interface pathologies, such as vitreoretinal tractions, epiretinal membranes (macular pucker)
- Foveal retinoschisis
- Glaucoma
