Optical Coherence Tomography (OCT) is used for the imaging of the retina and associated structures. It is an imaging technique that produces high resolution cross sectional images of optical reflectivity. It is based on the principle of Low-coherence Interferometry. This is analogous to the application of sound waves in B-scan Ultrasonography or X-rays in Computed Tomography (CT).
Scanning Laser Ophthalmoscopy or (SLO) is a method of imaging of the eye. It uses the technique of Confocal laser Scanning microscopy for diagnostic imaging of the retina or the cornea. It is helpful in the diagnosis of Glaucoma, Macular Degeneration and other retinal disorders.
It has applications in the following conditions :
- Vitreoretinal Interface Disorders
- Diabetic Retinopathy
- Central Serous Chorioretinopathy
- Age-related Macular Degeneration
- Retinal Vascular Diseases
- Chorioretinal Inflammatory Diseases
- Retinal Dystrophies
- Cornea and Anterior Segment
