The summary describes standard imaging and measurement techniques (OCT, SLO, Microperimetry) and data analysis (sensitivity mapping, statistical analysis of performance studies). There is no mention of AI, ML, deep learning, or any related concepts in the device description, intended use, or performance studies. The "Not Found" entries for "Mentions AI, DNN, or ML" and "Description of the training set..." further support this conclusion.
No
The device is indicated for use "as a diagnostic device to aid in the detection and management of ocular diseases." It does not provide treatment.
Yes
The "Intended Use / Indications for Use" section explicitly states, "It is used as a diagnostic device to aid in the detection and management of ocular diseases affecting the posterior of the eye."
No
The device description clearly states it is a non-contact, non-invasive, high-resolution device that is an add-on module to an existing OCT/SLO system. It utilizes hardware components like a super luminescent diode (SLD) and an organic light emitting diode (OLED) for light generation and stimuli, and involves physical interaction with the patient (depressing a button). This indicates it is a hardware device with integrated software, not a software-only medical device.
Based on the provided information, this device is not an In Vitro Diagnostic (IVD).
Here's why:
- IVDs are used to examine specimens derived from the human body. The intended use and device description clearly state that this device is used for in vivo viewing, imaging, and measurement of posterior ocular structures directly within the patient's eye. It does not analyze samples like blood, urine, or tissue outside of the body.
- The device description focuses on non-contact, non-invasive imaging and measurement of ocular structures. This is characteristic of imaging devices used for diagnosis, not IVDs.
- The microperimetry functionality involves subjective patient responses to light stimuli. This is a functional test performed on the living eye, not an analysis of a biological specimen.
Therefore, based on the definition of an IVD, this device does not fit that category. It is an in vivo diagnostic imaging and functional testing device for the eye.

Intended Use / Indications for Use
The Optos spectral OCT/SLO with Microperimetry is indicated for use for in vivo viewing, axial cross section, and three dimensional imaging and measurement of posterior ocular structures including retina, macula, retinal nerve fiber layer and optic disk. It is used as a diagnostic device to aid in the detection and management of ocular diseases affecting the posterior of the eye. In addition, cornea sclera and conjunctiva can be imaged with the system by changing the focal position.
The additional microperimetry functionality is indicated for use as a fixation examiner locating the patient's fixation site and by using the patient's subjective answer to light stimuli, generating a sensitivity map of the inspected retinal region.

Device Description
The Optos OCT/SLO Microperimeter is a non-contact, non-invasive, high-resolution device that is an add-on module to the FDA-cleared Optos Optical Coherence Tomography/Scanning Laser Ophthalmoscope (OCT/SLO). The OCT/SLO is a computerized instrument that employs non-invasive, low-coherence interferometry to acquire simultaneous high-resolution cross-sectional OCT and confocal images of ocular structure, including retinal nerve fiber layer, macula and optic disc of the eye. The light source used for this is a super luminescent diode (SLD).
The microperimetry test runs simultaneously with the confocal ophthalmoscope (SLO) and provides real-time tracking of retinal motion and patient fixation during the exam. Additionally, the patient's subjective response by depressing a button to light stimuli generates a sensitivity map for the inspected retinal region. The variable light stimuli are generated by an organic light emitting diode (OLED).

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)
a) Precision Study: A precision study was conducted that used 3 devices (each with a different operator). Each device was used to measure 4 normal subjects and 4 subjects with relevant eye pathology, with a total of 12 subject eyes measured across all three devices. The eye pathologies used for the study are early and internediate Age-Related Macular Degeneration, Geographic Atrophy, Diabetic Retinopathy (mild, moderate, severe), Macular Edema secondary to Diabetes, Retinal Vein Occlusion, Central Serous Retinopathy, Pattern Dystrophy, Epiretinal Membrane or Macular Hole. For each subject, one eye was evaluated using 3 replicates with repositioning at the start of each test.
A nested study design was used and the results achieved were as follows:-
Overall Mean: 16.16 dB for 12 Normal patients; 12.23 dB for 12 with pathology
Overall Standard Deviation: 1.735 dB for 12 Normal patients; 3.508 dB for 12 with pathology
Repeatability SD: 0.531 dB for 12 Normal patients; 0.682 dB for 12 with pathology
Repeatability SD Limit*: 1.49 dB for 12 Normal patients; 1.91 dB for 12 with pathology
*The repeatability limit is the upper 95% limit for the difference between repeated results. The Repeatability Limit is defined in ISO 5725-1 and ISO 5725-6 and equates to 2.8 times the repeatability standard deviation. It should be noted that the minimum to maximum repeatability for normal and eyes with pathology can vary by a factor of approximately 10. The table provides an estimate of the average repeatability, as determined during the clinical evaluation of the device. Users should note that repeatability varies between patients.
b) Agreement study: An in house study was conducted on 20 normal eyes and 20 diseased eyes using the Optos and the predicate device.
Excluding the extremes of the attenuation scale, the agreement between the devices approximates to ± 1 attenuation steps. At the attenuation scale extremes the agreement is ±2 steps as a worst case. .
Due to background illumination differences between the Optos and predicate device, there is a systematic difference of 1 ½ steps (3dB's) in the means for normal eyes. The mean difference between devices for diseased eyes is a ¼ step (0.5dB's). The mean difference between devices for diseased eyes is smaller than the mean difference between devices for normal eyes because, at higher levels of illuminance, the background level appears to have less of an effect on diseased eyes. This systematic bias between the Optos device and the predicate device was not consistent across all measurement values. For the normal eye, the average attenuation is from 17.2 to 19.0 dB. In this range, the difference between the predicate and the Optos device decreases from approximately 5.3 to 2.0 dB. For the diseased eyes, the difference (Predicate ~ Optos) increases from -4.0 dB to 2.0 dB when the average measurement ranges between 5.0 and 19.0 dB. This pattern was observed because the predicate reading is high mean attenuation values (approaching 20 dB's) and lower at low mean attenuation values when compared to the Optos OCT/SLO device. The differences in agreement between the Optos device and the predicate necessitate that measurements obtained from these two devices are not interchangeable.

- b) Agreement study
An in house study was conducted on 20 normal eyes and 20 diseased eyes using the Optos and the predicate device.
Excluding the extremes of the attenuation scale, the agreement between the devices approximates to ± 1 attenuation steps. At the attenuation scale extremes the agreement is ±2 steps as a worst case. .

For the diseased eyes, the difference (Predicate ~ Optos) increases from -4.0 dB to 2.0 dB when the average measurement ranges between 5.0 and 19.0 dB. This pattern was observed because the predicate reading is high mean attenuation values (approaching 20 dB's) and lower at low mean attenuation values when compared to the Optos OCT/SLO device. The differences in agreement between the Optos device and the predicate necessitate that measurements obtained from these two devices are not interchangeable.
Substantial Equivalence
In terms of microperimetry, the Optos OCT/SLO has the same intended use and indications for use and similar principles of operation and technological characteristics as the predicate device. The Optos and
2
the predicate device both require a patient response via a button push to light stimuli of varying intensity. The control, pattern and duration of these stimuli are very similar. The minor technological differences mainty relating to the use of a light emitting OLED in the Optos device and a backlif liquid crystal display (LCD) do not raise any new questions of safety and effectiveness. Thus, the Optos OCT/SLO (EOD) as not falso any not question to the legally marketed Nidek MP-1 Microperimeter (K023719)
