No
The summary mentions "computer analysis of these images" but does not provide any details suggesting the use of AI or ML algorithms. The absence of terms like "AI," "ML," "deep learning," or descriptions of training/test sets further supports this conclusion.
No
The device is described as a diagnostic tool used to determine the thickness and inner structure of the retina and to assess retinal thickness abnormalities and other pathologies. It does not provide treatment or therapy.
Yes
The device is intended to provide "computerized tomography of the retina in vivo" and is "indicated for assessing the area and location of retinal thickness abnormalities, such as thickening due to macular edema and atrophy associated with degenerative diseases, and for visualizing other retinal pathologies." This aligns with the definition of a diagnostic device, as it identifies and assesses medical conditions.
No
The device description explicitly details hardware components such as laser and conventional light sources, optics, a scanner, and a digital camera, indicating it is a physical device with integrated software, not a software-only device.
Based on the provided information, the RTA Model D Retinal Thickness Analyzer is not an IVD (In Vitro Diagnostic).
Here's why:
- IVD Definition: In Vitro Diagnostics are medical devices used to perform tests on samples taken from the human body, such as blood, urine, or tissue, to detect diseases, conditions, or infections.
- RTA Model D Function: The RTA Model D is described as a computerized slitlamp biomicroscope that performs tomography of the retina in vivo. This means it directly examines the retina within the living eye, without taking any samples from the body.
- Intended Use: The intended use clearly states it is for assessing retinal thickness abnormalities and visualizing retinal pathologies in vivo.
Therefore, because the RTA Model D operates directly on the patient's eye and does not analyze samples taken from the body, it falls outside the definition of an In Vitro Diagnostic device.

Intended Use / Indications for Use
The RTA Model D Retinal Thickness Analyzer ("RTA Model D") is a computerized slitlamp biomicroscope that is intended to provide manual and computerized tomography of the retina in vivo. The RTA Model D scans successive slit images on the fundus, without the need for a contact lens, to determine the thickness and the inner structure of the retina, both by observation of the slit images and by computer analysis of these images. It is indicated for assessing the area and location of retinal thickness abnormalities, such as thickening due to macular edema and atrophy associated with degenerative diseases, and for visualizing other retinal pathologies.

Device Description
The RTA Model D is a computerized electro-optical system comprised of two primary components, namely the optical head and the computer system. The main elements of the optical head include laser and conventional light sources, optics, a scanner, and a digital camera.
The RTA Model D is a computerized slitlamp biomicroscope that provides manual and computerized tomography of the retina in vivo. The RTA Model D scans successive slit images of the fundus to determine the thickness and the inner structure of the retina, both by observation of the slit images and by computer analysis of these images. The RTA Model D uses a solid-state laser source that emits green light at a wavelength of 532 nm. The beam is focused into a thin slit and, by means of a mirror, is directed toward the eye. The scanner and optics then detect the image of the illuminated portion of the retina and transmit the image to the digital camera. The digital camera then captures the image, where it can then be stored and analyzed by the computer system.

The RTA Model D is a computerized slitlamp biomicroscope that provides manual and computerized tomography of the retina in vivo. The RTA Model D scans successive slit images of the fundus to determine the thickness and the inner structure of the retina, both by observation of the slit images and by computer analysis of these images. The RTA Model D uses a solid-state laser source that emits green light at a wavelength of 532 nm. The beam is focused into a thin slit and, by means of a mirror, is directed toward the eye. The scanner and optics then detect the image of the illuminated portion of the retina and transmit the image to the digital camera. The digital camera then captures the image, where it can then be stored and analyzed by the computer system.
Substantial Equivalence:
The RTA Model D is a modification to the previously cleared RTA Retinal Thickness Analyzer. The only differences between the previously cleared RTA and the modified RTA Model D are:
- The Laser source has been changed from a green He-Ne operating at 1. 543nm to a green Solid State laser operating at 532nm;
- The interference filter has been modified accordingly; and 2.
- The laser beam optics has been modified to account for a slightly 3. different beam size.
Through design control assessment, including verification and validation testing, Talia has demonstrated that the modifications to the cleared RTA do not raise any new questions of safety or effectiveness. Accordingly, the RTA Model D is substantially equivalent.
