Optos Retinal Exam
The optical coherence topographer is one of the newest technologies available to an eye doctor. It provides a view of the different layers of the retina, giving information not otherwise visible.
The OCT creates cross-sectional images by assessing light reflections from the layers of the retina. Thus it functions in a manner similar to an ultrasound but using “light” instead of “sound”.
A detailed assessment is made of the structure and thickness of the layers of the retina, in the macula area and around the optic nerve as well as the optic nerve itself. The thickness measurement of the cornea is made as well as an anterior chamber angle assessment.
OCT images are especially useful in imaging the interface between the inner layers of the retina and the vitreous, the gel within the eye. The OCT helps the eye care professional diagnose, monitor, and treat diabetic retinopathy, age-related macular degeneration, glaucoma, macular holes, and several other eye diseases.
