COmparison of Clarus and Optos Ultrawide Field Imaging Systems for Inherited Retinal Disease

Summary

The goal of this research study is to compare two ultrawide field cameras to the gold standard imaging system to evaluate the back of the eye. The main question it aims to answer is the same results and information can be acquired from all of the cameras for evaluating and monitoring inherited retinal diseases (IRDs). Participants will: * undergo pupillary dilation * have photographs taken of the inside of the eyes using three different cameras

Interventions

• Device
  Spectralis FAF imaging

  Spectralis is a scanning laser ophthalmoscope which uses a blue light excitation wavelength of 488nm and a 500nm barrier filter to produce FAF images. Spectralis images 20-55 degrees of the retina.

• Device
  Optos imaging

  Optos is an ultrawide field imaging platform which images up to 200 degrees of the retina. It uses both a green-light excitation wavelength of 532nm and a red-light excitation wavelength of 633nm with an emission filter of greater than 540nm to produce FAF images.

• Device
  Clarus imaging

  Clarus 700 is an ultrawide field imaging system with similar retinal coverage to that of Optos. It uses Broad Line Fundus Imaging to produce blue FAF images at excitation wavelengths of 435-500nm and green FAF images at wavelengths of 500-585nm
