The device is a computerized interactive device that provides the user with a series of linear images oriented in vertical and horizontal planes on a video imaging screen that is designed to identify and correct visual dysfunction from reduced visual acuity by re-training the eye to utilize its optimal visual response in gaining an increased awareness of visual acuity through a series of training sessions. The device analyzes the patient's visual acuity deficiencies and sets a program for the user to increase the demand on the visual system resulting in an improvement of visual acuity. The device pre-programs a series of visual stimuli tasks and takes the patient through a series of interactive functions in identifying various objects on the video screen, and helps to provide an environment that increases visual response.
The Neurovision AA-1 System for the Treatment of Amblyopia is indicated for the treatment of amblyopia in patients 9 years or older.
1. Acceptance Criteria and Reported Device Performance:
| Acceptance Criteria | Reported Device Performance |
|---|---|
| Improvement in visual acuity | Average improvement of 2.5 lines of visual acuity from baseline best corrected vision |
| Consistency in visual improvement | Greater than 70% of subjects showed consistency in visual improvement |
| Retention of visual improvement after 3 months | Subjects were measured for their ability to retain visual improvement |
2. Sample size used for the test set and data provenance:
- Test Set Sample Size: The document does not specify the exact number of subjects in the test set. It mentions "subjects who completed the study with the long term follow-up three month visit."
- Data Provenance: Prospective, randomized, and controlled clinical investigation. The country of origin of the data is not explicitly stated.
3. Number of experts used to establish the ground truth for the test set and their qualifications:
Not applicable. The study evaluated the device's ability to directly improve visual acuity, which is a measurable physiological outcome, rather than relying on expert interpretation of diagnostic images or data for ground truth.
4. Adjudication method for the test set:
Not applicable. Visual acuity improvement was measured directly.
5. If a multi-reader multi-case (MRMC) comparative effectiveness study was done:
No, an MRMC comparative effectiveness study was not done. This study was a clinical investigation evaluating the direct effect of the device on patient visual acuity, comparing it to a placebo control group.
6. If a standalone (i.e., algorithm only without human-in-the-loop performance) was done:
Yes, a standalone study was essentially performed in the sense that the device itself (the computerized program) was the intervention being evaluated. The "human-in-the-loop" was the patient interacting with the device, but the performance being measured was the patient's visual acuity improvement as a direct result of the device's treatment program, not the device's diagnostic accuracy independently.
7. The type of ground truth used:
Visual acuity measurements (lines of visual acuity) objectively assessed before and after treatment, and after a 3-month rest period.
8. The sample size for the training set:
Not applicable. This device is a treatment system, not a diagnostic algorithm that requires a training set in the typical machine learning sense. The "program" within the device analyzes patient deficiencies and sets a program, implying an internal logic or pre-programmed rules rather than a trained AI model based on a training dataset.
9. How the ground truth for the training set was established:
Not applicable, as there was no explicit training set for a machine learning model. The device operates based on a "pre-programmed analysis of visual debilitation from amblyopia and a computerized software program that had analyzed the visual defect and carried the subjects through a series of sequential treatments designed to improve visual resolution capability." This suggests a rule-based or empirically derived program rather than one trained on a dataset with established ground truth.

INDICATION for USE:
The AA-1 System is indicated for the treatment of amblyopia using an interactive computerized program in patients 9 years or older suffering from amblyopia.
SUBSTANTIALLY EQUIVALENT TO:
The Neurovision AA-1 System is substantially equivalent to an ophthalmic Haploscope, a Class I Exempt medical device that is an AC powered device consisting of two movable viewing tubes, each containing a slide carrier, a low intensity light source for illumination of the slides, and a high

intensity light source for creating an afterimage. The intended use of the device includes amblyopia treatment and treatment of suppression.
The Neurovision device is equivalent to the haploscope (Preamendments Device 886.1340) with respect to the intended use- treatment of amblyopia. Additionally, the subject device is further equivalent to a haploscope in its principal of action, in that the low intensity light stimulus on the haploscope slides are used to bring light stimulus to the eyes when the target slides are moved with respect to each other.
The Neurovision AA-1 System is also substantially equivalent to the Humphrey Visual Field Analyzer (K852639) in that both devices collect diagnostic information through the use of software that interprets data information and reports diagnostic information useful to the user employing the device for further diagnosis and or treatment in the given indication for use.
Lastly, the Neurovision AA-1 System is substantially equivalent to an Eye Shield (K896171) Eye Garter Company, and Eye Shield (K841599) Storz Instrument Company, that is customarily used to cover the good eye during amblyopic treatment of the amblyopic eye during treatment sessions to improve visual acuity in the affected eye.
DEVICE DESCRIPTION:
The device is a computerized interactive device that provides the user with a series of linear images oriented in vertical and horizontal planes on a video imaging screen that is designed to identify and correct visual dysfunction from reduced visual acuity by re-training the eye to utilize its optimal visual response in gaining an increased awareness of visual acuity through a series of training sessions. The device analyzes the patient's visual acuity deficiencies and sets a program for the user to increase the demand on the visual system resulting in an improvement of visual acuity. The device pre-programs a series of visual stimuli tasks and takes the patient through a series of interactive functions in identifying various objects on the video screen, and helps to provide an environment that increases visual response.
CLINICAL INVESTIGATION
A prospective randomized and controlled clinical investigation was conducted to evaluate the potential for improvement and retention of visual acuity in persons of 9 years of age or older who suffer from amblyopia (lazy eve) from any source. The investigation consisted of a series of treatment sessions in an interactive environment using a pre-programmed analysis of visual debilitation from amblyopia and a computerized software program that had analyzed the visual defect and carried the subjects through a series of sequential treatments designed to improve visual resolution capability. The investigation consisted of visual stimuli projected onto a video monitor and patient responses being recorded by the click of a computer mouse responding to the various visual stimuli. The computerized program archived the responses and analyzed the responses in preparing the subjects for the subsequent treatment session. Completion of the treatments was established when the subjects no longer improved visual acuity, and were stable to the same visual acuity readings for three consecutive visits. After a three month rest period from treatments, the subjects were measured for their ability to retain the visual improvement that was gained during the first phase of the treatments.
The investigation of the device demonstrated that the subjects who completed the study with the long term follow-up three month visit improved visual acuity performance by an average of 2.5 lines of visual acuity from their baseline visual acuity best corrected vision. Greater than 70% of the subjects showed consistency in visual improvement. The control group treated by placebo treatment showed no improvement and was detected earlier in the study
