No
The description focuses on signal acquisition, processing algorithms (spatial filtering, artifact rejection), and data visualization, without mentioning AI/ML techniques. The "Mentions AI, DNN, or ML" section is explicitly marked as "Not Found".
No
The device is described as an "electrodiagnostic device" used to measure and display electrical signals from the visual system for diagnosis, not for treatment.
Yes
The "Intended Use / Indications for Use" states that the device is "used to generate photic signals and to measure and display the electrical signals generated by the retina and the visual nervous system" and "displays digitized electroretinogram (ERG), visual evoked potential (VEP) and sensory electro-oculogram (EOG) signals, power spectra and topographic maps." It further clarifies that these functions are "for use with patients who are experiencing visual system abnormalities," indicating its role in identifying and characterizing medical conditions.
No
The device description explicitly mentions hardware components like LEDs, a monitor, and recording channels using conventional EEG electrodes, which are not provided but are necessary for the device's function. The software analyzes the data acquired by this hardware.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- IVD definition: In vitro diagnostics are tests performed on samples taken from the human body, such as blood, urine, or tissue, to detect diseases, conditions, or infections.
- Device function: The E3 and Profile system is an electrodiagnostic device that measures electrical signals generated by the retina and visual nervous system in vivo (within the living body). It does not analyze samples taken from the body.
- Intended Use: The intended use clearly states it's used with patients experiencing visual system abnormalities, implying direct interaction with the patient's body to measure physiological responses.
Therefore, the device falls under the category of a medical device used for physiological measurement, not an in vitro diagnostic device.

Device Description
Photopic stimuli are presented to the patient using LEDs or a monitor, using various number of elements in separately stimulated fields. Various modes are available for preferential stimulation of different retinal mechanism and isolation of signal from different retinal lavers. Data is recorded by up to 5 recording channels using conventional EEG electrodes (not provided with the device).
During the period of time that the system is acquiring data (1-20 minutes), there is a real time display of the raw and processed data presented to the user. Once the resulting individual waveforms are acquired, the signals are analyzed by software using algorithms for spatial filtering and artifact rejection. Data may be presented in a number of forms, including waves recorded at each of the points tested, color plots, or 3D topographical representation.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)
The non-clinical testing completed for the E3 and Profile included these three major categories of testing:
Technical tests:
Internal hardware, firmware and software component tests, packaging and labeling tests. Software verification and validation have been tested against their specifications and according to IEC 62304: 2015.
Functional tests:
The different functions needed to measure electroretinograms (ERG), visual evoked potentials (VEP) and sensory electro-oculograms (EOG) were tested according to the recommendations of the International Society of Clinical Electrophysiology of Vision (ISCEV).
Compatibility tests:
Compatibility of the equipment and software with the major types of electrodes was tested for the different exams performed by the equipment.
Conclusion:
The E3 and Profile and the Vision MonPackONE system have the same intended use and indications, technological characteristics and principles of operation. Any technological differences between the E3 and Profile and its predicate does not present any new issues of safety or effectiveness. Testing has demonstrated that the E3 and Profile is substantially equivalent to the predicate device.

Dear Jeffrey Farmer:
We have reviewed your Section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (Act) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. Although this letter refers to your product as a device, please be aware that some cleared products may instead be combination products. The 510(k) Premarket Notification Database located at https://www.accessdata.fda.gov/scripts/cdrh/cfdocs/cfpmn/pmn.cfm identifies combination product submissions. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration. Please note: CDRH does not evaluate information related to contract liability warranties. We remind you, however, that device labeling must be truthful and not misleading.
