Purpose	to perform imaging in patients with posterior uveitis and compare Fluorescein angiography (FA) and Indocyanine green angiography (ICGA) with Heidelberg Spectralis® HRA and Optos.
Methods	single-center, observational case series, 50 eyes received ultra-widefield FA and ICGA using the Optos® panoramic P200Tx imaging system and the Heidelberg Spectralis® HRA+OCT system's non-contact ultra-widefield module. The photos were captured as single, unguided shots focused on the macula. The general area inside the four visible quadrants was computed and compared between the two devices. Additionally, three masked reviewers assessed each quadrant per eye to determine which modality photographed the retinal vasculature more peripherally.
Results	FA and ICGA groups had their Optos and HRA calculated. Except for subretinal fluid separation (p=0.843>0.05), all other factors for FA were statistically significant. Consequently, there is no statistically significant difference in any of these factors between the Optos and HRA for ICGA groups.
Conclusion	Optos is more widely used than Spectralis HRA. However, we cannot assume the superiority of one device over the other for imaging in patients with posterior uveitis. Nevertheless, our study revealed that angiograms obtained with Spectralis HRA were more accurate and precise for detecting certain lesions. As such, Additional research must be conducted to draw further conclusions.
