No
The description mentions "basic analysis" and "user developed algorithms," but there is no mention of AI, ML, or related terms like neural networks or deep learning. The technology described is a standard digital imaging system with basic measurement software.
No.
The device is described as an ophthalmic diagnostic tool intended to track the progress of glaucoma by monitoring changes in the appearance of the Optic Disc, which is a diagnostic function, not a therapeutic one.
Yes
The Intended Use / Indications for Use section explicitly states that the Discam® Digital Imaging System "is intended to be used as an ophthalmic diagnostic tool." It also details its use in tracking the progress of glaucoma by monitoring changes in the Optic Disc, which is a diagnostic activity.
No
The device description explicitly details hardware components including a CCD Stereo Camera, image capture board, PC, rise and fall table, chin rest, fixation lights, power supply, and halogen lamp. While it includes software for analysis, it is not solely software.
Based on the provided information, the Discam® Digital Imaging System is not an In Vitro Diagnostic (IVD) device.
Here's why:
- IVD Definition: In Vitro Diagnostics are devices intended for use in the examination of specimens derived from the human body (such as blood, urine, tissue) to provide information for the diagnosis, monitoring, or treatment of disease.
- Discam® Function: The Discam® Digital Imaging System directly images the Optic Disc (Optic Nerve Head) within the living human eye. It does not analyze specimens taken from the body.
- Intended Use: The intended use is to be an ophthalmic diagnostic tool to track the progress of glaucoma by monitoring changes in the appearance of the Optic Disc. This is done through direct imaging of the anatomical structure.
The device is a medical imaging device used for in-vivo examination, not an in-vitro diagnostic device.
N/A
Intended Use / Indications for Use
The Discam® Digital Imaging System is intended to be used as an ophthalmic diagnostic tool, which is complimentary to other accepted diagnostic technologies, to track the progress of glaucoma, relative to monitoring changes in the appearance (size and shape) of the Optic Disc.
The Discam® Digital Imaging System is intended to be used to evaluate the Optic Disc, (Optic Nerve Head). It is used in the same fashion as a Fundus camera, except that it's field of view is narrower, in order to focus exclusively on the Optic Disc, (Optic Nerve Head). Evaluation of changes in the size and shape of the Optic Disc, (Optic Nerve Head), is useful in monitoring the progress of patients with Ocular Hypertension, and Glaucoma.

Device Description
The Discam® Digital Imaging System consists of a CCD Stereo Camera that captures stereo images through an image capture board interfaced with a PC with the minimum requirements mages arough an RAM, 1 GB Hard Disc, 133 MHz CPU, Windows® 95 OS. The CCD stereo camera and housing is mounted on a standard rise and fall table, along with a standard adjustable patient chin rest.
The patient fixates on fixation lights, (fixed LEDs), and the operator views the image on the PC's monitor. Image capture, which is accomplished in 0.2 seconds, is initiated by pushing a iov stick.
Windows® based software allows basic analysis, (measurement of cup and Disc, cup to Disc ratio), of the captured images, using either our optional analysis software, or third party software with user developed algorithms, and data archiving.
The camera measures 370 mm Depth x 360 mm Height x 108 mm Width. It is powered by a switch mode power supply 100 V to 220 V, 50 Hz to 60 Hz.
Illumination is from a 12 Volt 55 Watt Halogen Lamp. There is no flash.

Dear Mr. Dawson:
We have reviewed your Section 510(k) notification of intent to market the device referenced above and we have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to 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). You may, therefore, market the device, subject to the general controls provisions of the Act. 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.
If your device is classified (see above) into either class II (Special Controls) or class III (Premarket Approval), it may be subject to such additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 895. A substantially equivalent determination assumes compliance with the current Good Manufacturing Practice requirements, as set forth in the Quality System Regulation (QS) for Medical Devices: General regulation (21 CFR Part 820) and that, through periodic (QS) inspections, the Food and Drug Administration (FDA) will verify such assumptions. Failure to comply with the GMP regulation may result in regulatory action. In addition, FDA may publish further announcements concerning your device in the Federal Register. Please note: this response to your premarket notification submission does not affect any obligation you might have under sections 531 through 542 of the Act for devices under the Electronic Product Radiation Control provisions, or other Federal laws or regulations .
