Current Tests

An Easier, Faster Approach to Visual Field Testing

90 Seconds Glaucoma Perimetry

16/64 Point Neurological Perimetry

Tests are easy to understand and perform for children and the elderly
First, the patient is presented with a central target. Subsequently, a peripheral stimulus appears. Then, utilizing eye-tracking, BulbiCAM detects whether the patient looks towards the new spot. The contrast to a counterintuitive eye-brain-hand push button reflex arc is profound.

Saves time for medical personnel
Our visual field assessment for glaucoma takes 90 seconds per eye, on average. The examiner spends less time explaining the procedure to the patient. Because the test is so intuitive, retesting is rarely needed.

Early glaucoma detection
SAP often doesn’t show signs of damage before half of all ganglion cells are lost. This is alarming. Both finished and ongoing studies suggest that eye movement
perimetry recognizes field damage where SAP detects none.

Pupillometry and RAPD Log Measurement

Dynamic Pupillometry

Rapid RAPD Assessment

Efficient workflow
Detailing pupillary reactions, measuring pupil diameters accurately in darkness and light, and quantifying RAPD is often very time consuming for the clinician.
This test takes less than a minute to perform, and is easily applied by a technician prior to dilation.

Intuitive Nystagmography

Rapid, straightforward, and objective characterization of nystagmus
Our nystagmograph captures video at 400 fps and accurately graphs eye movements. In the intuitive interface, direction, amplitude, frequency, jerk/pendular
characteristics, and saccade shape are determined in a minute or two. Eye movements replay at different speeds. Now, disease progression and treatment efficacy are easily monitored.

The interface is proprietary and next-generation. Please be in touch for a demo.

Semi Automated Ptosis Grading

Accurate, effort-saving ptosis grading
Using captured eye images, ptosis measurements are done in seconds.
