A study comparing the UWFFA imaging capabilities of the Optos 200Tx and a recently introduced module-based system confirms that the optomap® provides the widest field of view. Results published in Clinical Ophthalmology demonstrated that both systems provided excellent imaging of the peripheral retina although the Optos optomap covered at least 50% more retinal surface area with a single, non-steered shot and provided a wider view of the retina temporally and nasally, with the comparator system providing greater visualization of the peripheral vasculature of the superior and inferior retina.
