ADVANTAGES:

Effective - increases accuracy and

diagnostic measurement capability.

As a consequence, improves the

surgical success rate and facilitates

post-surgery monitoring.

Flexible - allows to explore many of

the eye positions.

Documented - generate

documentary evidence appended to

the clinical history.

Pre-programmable - with scan

patterns defined by the specialist.

Easy to use - provides the

possibility to delegate scanning

tasks to physician assistants.

Versatile - allows the

implementation of other features

related to ocular motility.

Videoculograph (VOG) with laser projection system, integral with the patient's head, that allows to measure and accurately diagnose complex deviations of gaze in all di-

rections. APPLICATIONS: Measures ocular deviation at any point in space.

Measure strabismus.

Measure nystagmus.

Measure pupillary dynamics.

Measure the field of ocular motility.

This medical device is equipped with two cameras with infrared vision, that allows recording eye movements with great preci-sion, and with a laser projector able to pro-

jects at any point in space. Components: 1. Laser projector 2. Cameras with infrared vision 3. System subject to the head 4. Electronic circuits

The device includes an ad hoc computer with the necessary applications preinstalled.

Endotrophy:

Left Endotrophy + Left Hypertrophy:

The right eye is following properly the horizontal pattern, while the left eye deviates to the left. As the patient follows the pattern to the left, an increasing hypertrophy appears in

the left eye.

On the eyes’ pictures, for pattern dot number 5 (eyes look-ing at coordinate 10,0) the left eye deviation towards the right is horizontal=19.5° and vertical=-9.4°. For dot number 8 (eyes looking at coordinate 40,0) the left eye deviation towards the right is horizontal=9° and vertical=-20.5°.

Left Endotrophy + Left Hypertrophy + Alternate Fixation:

It can be observed that the eye fixa-tion to vertical pattern changes ac-

cording to the point examined.

For pattern dot number 2 (coordinate 0,20) we observe that the fixating eye is the left, while the right eye looks inward. The visual difference between right and left eye is horizon-tal=23.1° and vertical=-2.9°.

For pattern dot number 5, the fixat-ing eye is the right one, while the left eye looks inward. Visual deviation of the right eye towards the left is hori-zontal=17.7° and vertical=-10.6°.

Right Exotrophy:

It can be observed that the left eye fol-lowed correctly the vertical pattern, while the right eye maintains a steady drift to-

wards the right on all points.

In the pictures above, looking at dot num-ber 1 (coordinate 0,0), it can be observed the deviation of the right eye compared to the red cross (0,0).

Pupil Dynamics:

The blue graph presents the rapid re-sponse of the right pupil diameter over time, as a result of two flashes of light. Similarly, the red graph shows the

rapid response of the left pupil diame-ter as a result of three flashes of light.

Nystagmus:

The device detects the vibra-tion of the eye in the horizontal direction, while almost no ver-tical oscillation. The average

amplitude of motion is 5 mm with a pendulum type swing.

BCN Innova is a technology start-up founded in 2008 in Barcelona, Spain. Our mission is to provide the ophthalmological sector with technological so-lutions based on artificial vision, that may support specialist on the diagno-sis of ocular dysfunction, improving measurement accuracy and serving as an standard for post-surgery monitoring.
