Intended Use

The Neucodia system is an electrophysiological device that generates photic stimuli, and records, processes and analyzes the resultant visual evoked potential (VEP) signals for the study of central visual functions.

Device Story

Neucodia is an electrophysiological test system for studying central visual functions. It presents visual stimuli on a monitor to a patient; records EEG signals via scalp electrodes; and processes these signals to extract visual evoked potentials (VEPs). The system performs noise filtering, artifact rejection, and frequency/time domain analysis. Outputs include EEG epochs, spectrum, Fourier components, and statistical measures (means, deviations, signal-to-noise ratio). Used in hospitals, clinics, physicians' offices, and research labs by neurologists, eye-care professionals, and trained technicians. The device aids clinicians in assessing visual pathway integrity and function.

Clinical Evidence

Clinical testing evaluated system repeatability and reproducibility. Repeatability was assessed via 10 sequential tests per subject. Reproducibility was assessed across three visits using different devices, operators, and electrode reapplication. Metrics included VEP multi-variable statistics and signal-to-noise ratio.

Technological Characteristics

Electrophysiological EEG system; hardware for signal amplification and A/D conversion. Standards: UL 60601-1, IEC 60601-2-26, EN 60601-1-2, ISO 15004-2. Features frequency and time domain analysis software. Connectivity via standard EEG electrode inputs.

Indications for Use

Indicated for normal observers, individuals at-risk for visual pathway dysfunction, or individuals with confirmed ophthalmic disorders for the study of central visual functions.

Regulatory Classification

Identification

An evoked response photic stimulator is a device used to generate and display a shifting pattern or to apply a brief light stimulus to a patient's eye for use in evoked response measurements or for electroencephalogram (EEG) activation.

### Identification of Legally Marketed Predicate Devices 2.1

The Neucodia system is substantially equivalent to Roland Consult's RETI-Port-Scan (K023525) and LACE Elettronica's GLAID Ocular Electrophysiology Device (K043367). The Neucodia device features are substantially equivalent to the predicate devices with respect to the device's general design concept, operational procedure, data processing methodology, data acquisition conditions, and indications for use. All the devices are electrophysiological (EEG) test systems that consist of electrical hardware and software to produce visual stimuli, EEG signal recording and processing for extraction of visual evoked potentials (VEPs). All the devices are intended to be used by trained medical professionals for the study of central visual functions.

# 2.2 Device Description

Visual stimuli are presented to the patient on the stimulus monitor. Visual evoked potentials are extracted from EEG epochs recorded via medical-rated EEG electrodes (not included in the device) attached to the scalp of the patient. Once the recording is complete, the digitized EEG data are processed by the software algorithm for noise filtering, artifact rejection, frequency and time domain analysis. The results are displayed on the user's monitor: EEG epochs, spectrum, Fourier components, and statistical measures (e.g., means, deviations, and signal to noise ratio).

### Indications for Use 2.3

The Neucodia system is an electrophysiological device that generates photic stimuli, and records, processes and analyzes the resultant visual evoked potential (VEP) signals for the study of central visual functions

#### Performance and Validation 2.5

Software: Verification and validation

Safety test: UL 60601-1, IEC 60601-2-26, EN60601-1-2, ISO15004-2 System: Bench testing for power supply requirement, amplifier gain and CMRR Clinical testing:

VEP multi-variable statistics and signal to noise ratio were measured to produce system repeatability and reproducibility. 10 repeated sequential tests were performed on each subject to obtain repeatability performance data. In addition, each subject had three visits for the same repeated tests using different devices and with different operators and reapplication of electrodes to obtain reproducibility performance data. The clinical test results are described in Section 4.2.18, User's Manual and Section 5.2.3, Device Description.
