Summary

OCt.IN.N is a national, monocentric, prospective, observational cohort study evaluating the utility and applicability of Optical Coherence Tomography (OCT) in the diagnostic workup and longitudinal monitoring of neurological diseases.

840 patients with Central Nervous System neurological diseases (Multiple Sclerosis, Alzheimer's disease, Parkinson's disease, migraine/headache) and 210 age-matched healthy controls will undergo OCT examination at baseline and at 6, 12, 18, and 24 months of follow-up at IRCCS San Raffaele Hospital, Milan, Italy.

OCT is a non-invasive, rapid, and reproducible technique that automatically measures the thickness of individual retinal layers. Retinal layer thicknesses and their longitudinal changes will be correlated with established clinical scales, neuroimaging, and biological markers used in routine neurological practice.

DEVICE

Optical Coherence Tomography (OCT) - Heidelberg SPECTRALIS HRA+OCT

Spectral-domain Optical Coherence Tomography (OCT) performed using the Heidelberg SPECTRALIS HRA+OCT device (Class IIa CE-marked medical device). The procedure is non-invasive: the patient sits in front of the device and is asked to fix a target (light or cross) through a lens. No drugs or contrast agents are administered. OCT automatically acquires images of the macular region (where GCL and IPL are most represented) and the optic nerve head region (where RNFL is most represented), providing automated measurements of the thickness of individual retinal layers. OCT is performed at baseline and at follow-up visits at 6, 12, 18, and/or 24 months. Ophthalmological evaluation may be performed at the investigators' discretion if OCT images, clinical symptoms, or medical history suggest concurrent ocular pathology. Patients with a known diagnosis of epilepsy or history of epileptic seizures will not undergo specific imaging modes using clearly visible light sources (MultiColor, FA, BAF).
