About the RHA

Share This Page:  

The RHA™ is an integrated system with two distinct components:

RHA™ Instrument

The RHA™ instrument is a multi-spectral imaging digital ophthalmoscope with a patented optical system that captures high resolution image data through the retinal and subretinal layers.

Multi-spectral imaging extends the simple color based analysis eye care professionals use to distinguish between ocular structures.  It both expands the examination wavelength range from green to invisible near infrared wavelengths of light and generates the probe wavelengths to separate specific spectral regions for enhanced visibility and discrimination. The combination of the images and extracted data points provides an enhanced view of the eye.

The photographs below show the dimensions of the instrument.

RHA Report™

The RHA Report™ is a data analysis and reporting software package that processes and analyzes the RHA™ image data sets, creating an intuitive program for professional assessment and diagnosis of the patient’s ocular and general health.

The RHA Report™ software is also patient friendly and can be used for an informative discussion that can enhance the doctor-patient relationship. Effective communication will improve a patient’s compliance with respect to treatment.

“This technology promises to not only revolutionize clinical practice, but also greatly enhance our understanding of the pathophysiology of retinal and choroidal disease.”
