DIVE-MEDICAL TECHNOLOGY

Accurate, objective, and repeatable evaluation of several visual functions

Fast and accurate vision diagnosis even for non-collaborative patients

DIVE features a high-resolution touchscreen for visual stimuli display and interaction, an eye tracker to capture the patient’s response to those stimuli, and an ergonomic case designed for optimal positioning of the device.

It is non-invasive and specially designed for pediatric patients. Combining eye tracking technology with carefully designed stimuli and algorithms, DIVE allows us to perform faster, more accurate, and more comfortable exams of the visual function even in non-collaborative patients.

Our tests

The application includes several visual tests based on validated stimuli for each age, real time adaptive presentation of the stimuli during the tests following different looking paradigms. Immediate automated analysis and interpretation of the outcomes with normative references throughout chidhood.

Visual acuity

Examination of the spatial resolution of the visual system with a grating visual acuity test at 65 cm and recognition test, with letters or symbols, at 1/2/3 m distance.

Contrast sensitivity

Measurement of the ability to distinguish a grating pattern with different luminances and spatial frequencies and generation of the contrast sensitivity curve.

Oculomotor control

An exhaustive description of fixation stability, saccadic and smooth pursuit performance.

Colour perception

Measurement of chromatic discrimination in each of the three colour vision axes (protan, deutan and tritan) and detection and quantification of the severity of any colour perception defect.

FAQs

DIVE is a platform consisting of a device and two software modules, DIVE Vision Exam and DIVE AI Vision Screening. The features of each are as follows:

DIVE Vision Exam allows automated testing of oculomotor control, visual acuity, contrast sensitivity and colour perception. It makes it possible to explore each visual ability in isolation or as a battery, monocularly or binocularly.

DIVE AI Vision Screening performs a comprehensive and automatic analysis of the entire visual function. It includes a battery of audio-guided tests that, once have been finished, the device process with an Artificial Intelligence system and displays the risk of abnormal visual development, strabismus or colour vision defects.

DIVE incorporates features that favor the exploration of visual function in uncooperative patients in patients who do not collaborate well with standard tests in ophthalmology and optometry:

  • The design presents an interface approachable to any patient, especially children, a device that is clearly perceived as harmless and non-invasive. The device itself guides the child in the assessment, so he or she is not distracted by other people or voices.
  • The height required to perform the visual examination allows young children to sit on their parents’ laps, so that they are calmer during the process.
  • The interface and colors are attractive, smooth and do not require the intrusion of healthcare personnel, which can be classically perceived as threatening to some children.
  • The device has active controls of the attention and quality of the measurements obtained in real time, so that the device itself displays stimuli with music to re-capture the patient’s attention in case he/she has momentarily lost it.
  • The evaluation with the device can be performed in any quiet room as long as there is no light or very dim light. In this way it is possible to increase the attention on the screen as it is the only stimulus present for the patient.

DIVE is designed to expand the capabilities of the eye care professional. Obtaining reliable visual function metrics in a matter of minutes is of interest in any clinical scenario. In addition, the autonomous administration of the tests does not require qualified personnel and will help to increase the daily patient portfolio of the practice.

A technician can perform the study of visual skills prior to the consultation. In this way, the ophthalmologist or optician can receive the patient with a lot of information about his or her general visual status, which will favor the patient’s care: less consultation time since we can guide the diagnosis more quickly. Likewise, the number of patients who cannot be scanned is reduced.

Although the first version of DIVE is more focused on pediatric patients, given that the current normality curves go up to 15 years of age, this version can be used in any type of patient to obtain objective measures of visual function.

Currently, adapted versions with more adult stimuli are being developed for non-pediatric patients and the normality curves will be extended to a full age range.

Any alteration in the main visual functions (visual acuity, contrast sensitivity, oculomotor control and colour vision) as well as the presence or absence of strabismus (in the Screening version).

The device is in the final stages of obtaining CE marking. CE marking is the Medical Device manufacturer’s declaration that a product complies with the essential requirements of all relevant European Directives. The Directives describe the safety and performance requirements for medical devices in the European Union (EU).

The device generates customized reports for each of the skills evaluated, showing the values obtained for each metric. Graphs are also shown with the level of each parameter with respect to a normative base by age.

It is possible to obtain a PDF report of each scan that can be printed or sent to an e-mail.
