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
Inclusion Criteria: * Participants 18 years and older with a clinical and/ or genetic diagnosis of IRD recruited either from the clinic and/or the Inherited Ocular Disease Registry to participate in this trial * Participants that are willing to participate as evidenced by signing the written informed consent Exclusion Criteria: * Presence of ocular conditions other than an IRD which may affect the quality of ocular imaging including but not limited to advanced cataracts, corneal disorders, nystagmus, vitreous hemorrhage, or poor dilation * Presence of ocular conditions other than an IRD whi…
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.
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.
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
