What is OCT?
The OCT (optical coherence tomography) it's an exam non-invasive which provides high-resolution images of sliced (tomographic) scans of the cornea, the central part of the retina (macula) and the head of the optic nerve (papilla).
The operating principle of interferometry is similar to that of ultrasound, exploiting the reflection of a harmless laser beam instead of sound waves.
What is OCT used for?
The OCT It is indicated in patients in whom a disease is suspected of the cornea, retina, and optic nerve. It provides information on structural alterations of the retina, precisely identifying their location. It also allows for the automated measurement of the thickness of the tissues (useful for monitoring the evolution of diseases over time) and of the cornea, analyzing the structural alterations and identifying the depth of the lesions.
Optical coherence tomography is irreplaceable for the diagnosis, monitoring, and clinical decision-making regarding the treatment of many important retinal diseases.
How long does OCT last and how is it performed?
It is a simple and quick execution (10-15 minutes); The patient is made to sit in front of the instrument, resting his chin and forehead on special supports, then the operator asks him to focus on a luminous target.
At the HUB Vicenza Polyclinic and Analysis you can book an eye examination with OCT exam with the Dr. Francesca Militello – Ophthalmologist Oculoplastic surgeon, with the Dr. Federico Friede, with the Doctor Paolo Pezzato.
