IMPORTANT โ€” PLEASE READ OptoReflex is a set of visual stimuli and observation tools for teaching and for supporting the examiner's own observation. It is not a medical device, it does not diagnose, and it must not be used to make medical decisions. Always consult a physician and use validated equipment for medical assessment. OptoReflex turns your iPhone or iPad into a pocket kit of classic neuro-ophthalmology stimuli for clinicians, students and educators. WHAT'S INCLUDED โ€ข Optokinetic drum (OKN) Full-screen moving stripes act as a digital optokinetic drum. Choose colors, speed, stripe width, pattern and direction, with a live preview. Speed can be shown in degrees per second for the viewing distance you set. โ€ข Smooth pursuit and saccade targets A target that glides (pursuit) or jumps between points (saccades) along horizontal, vertical or circular paths. Adjustable speed, amplitude, size and color. โ€ข Nine gaze positions A target that steps through the nine positions of gaze while you observe the eyes. โ€ข Pupillary light reflex โ€” observation The rear camera works as a magnifier with macro focus, and the flashlight delivers timed stimulus sequences (direct, consensual, alternating light, light/dark) with countdown and voice cues. For teaching, an approximate pupil diameter is shown together with the outline the app detected. It is an estimate based on an assumed iris diameter, not a clinical measurement. โ€ข Pupil gauge Circles from 1 to 9 mm at actual size on the screen, like the gauge printed on clinical penlights, for visual comparison by the examiner. Size can be calibrated with a standard bank card. โ€ข Amsler grid A standard grid with a central fixation dot, normal and inverted modes, drawing of the areas the person describes, and side-by-side comparison by eye. RECORDING AND PRIVACY Sessions can be recorded with the device camera. Videos stay in a private area on your device, with optional name or ID and date, and can be protected with Face ID. Nothing is uploaded. LANGUAGES English, Spanish, Portuguese, French, German, Italian, Chinese, Japanese, Arabic and Russian, with an in-app selector.
