Highlights

The Opto AP300 features Static, Kinetic, Blue on Yellow and Flicker Perimetry capability, enhanced variable colour stimulus and size testing as well as a state of the art Digital Eye Tracking System.

Accurate Results: The Stimuli of the Opto AP300 Perimeter is projected into an array of very dense points resembling accurate pattern of receptor cells that make up the neural architecture of the retina. This results in presentation of a circular grid pattern providing most precise map of the visual field, however for those who are familiar with the conventionally known Humphrey pattern, the users can choose for the stimulus projections to follow the square grid layout.

Optical Stimulus Correction System: The world’s first optical stimulus correction system ensuring that the projected stimuli appear precisely within the selected Goldman parameters across the entire field. As for all other Projection-Type Perimeters presently in the market, their projected stimuli becomes oval-shaped usually in the test fields above 30° degrees making the clinical results less precise.

Advanced Digital Eye Tracking System: The Opto AP300 features one of the most advanced Digital Eye Tracking monitoring systems in the market. This constant and precise monitoring of the patients’ position results in rapid and accurate exams.

The Eye Tracker System can be set to auto-pause when statistical losses of fixation are detected, or set to perform an entire examination providing results disregarding fixation losses, making the examination simple and convenient.

Examination Area Expansion: The physician has the ability to commence the visual examinations selecting fields as small as 10° degrees, yet should peripheral visual losses be detected they can easily expand the test area as much as required whilst continuing the initial examination.

This significant feature adds to the overall convenience for both patient and the operator as it significantly saves time eliminating the need of further retesting.

Expansion Area Retest and Defect Verification: A simple point and click of the mouse enables a quick selection and retest of the suspect points whilst examination. This unique feature enables verification of any suspect areas resulting in either poor fixation or visual loss, and facilitates in straightforward testing of specific regions.

Customizable Examinations: The user-friendly Test Editor function allows easy customization and creation of test fields for an instant examination compatible with all system strategies.

This significant function is ideal when tracking the disease progress saving further the examination time by focussing on the affected areas only, testing patients with neurological impairments or customization for research needs.

User Friendly Software: The Opto AP300 Perimeter software was designed to be intuitive and simple to use, even for operators with limited computer skills. Interactive system menus provide customizable sounds alerting losses of fixation and cover all standard comments. Provided information is efficient and comprehensive, reducing the time spent in preparing, reviewing, printing and sharing the patient exams. The Opto Perimeter operating software terminology and language can be easily customized to individual needs.

The enhanced patient database algorithm is known to be fully recoverable even after PC is formatted, can be set to automatic daily backup to HDD/CD/DVD and is well protected from accidental deletion.

Operating System Upgradeability: Opto ensures ongoing operational software upgrade capability, which is easy and evolutionary allowing our customers to keeping pace with their practice needs as well as the latest developments perimetry testing.

Data and Practice Management Integration: The Opto AP300 integrates with numerous practice management systems as well as other Opto devices. Network data sharing or remote system accessibility and operation is also possible adding further efficiency to dynamic practices eliminating multiple patient and data entries.

Fast Examination Times: Several techniques are available to reduce examination time, including optimised strategies such as FastScan, Screening, Fast Threshold and Smart Threshold, as well as enhanced fixation methods and adaptive patient response. For patients with large field losses, the use of custom or neurological test methods is available.

The new Kinetic as well as the Smart Threshold strategy tests randomly selected points, and when a reduction in visual threshold is sensed the system adds points adjacent to the area of interest for accurate testing. This permits an examination to be carried out in less time whilst maintaining maximum accuracy.

Examination Reliability: The Opto AP300 Perimeter features many integrated tools assuring high reliability of the examination results utilizing Goldman Standard compatible Global and Reliability Indices recording.
