Clinical research with the rtx1 AO camera

Age-related macular degeneration

Publications report that the rtx1 showed AMD-related retinal changes in higher details than conventional imaging. Different types of drusen had distinct appearances on rtx1 images. A new examination method using rtx1, called gaze-dependent AO imaging, further enhanced the contrast of small drusen, and enabled detecting more drusen than on color fundus images. Furthermore, the border of geographic atrophy is more sharply visualized on rtx1 images than on autofluorescence images, which enabled detecting and measuring GA progression over timescales as short as 3 weeks.

Webinar on September 20

3 professors in Ophthalmology will share their experience and vision about the use of rtx1 AO camera in AMD.

Inherited retinal diseases

A wide array of inherited retinal diseases has been investigated with rtx1. In all of them, rtx1 revealed microscopic changes in various retinal structures. Regarding alterations of the cone cell mosaic, rtx1  enabled quantifying them, and in some cases even before clinical changes. Longitudinal studies have shown that rtx1 also assessed RP progression over shorter timescales than visual acuity or OCT biomarkers.

Diabetes and diabetic retinopathy

In several clinical studies, the rtx1 revealed multiple microscopic abnormalities in the retinas of diabetic patients, even in eyes without diagnosed retinopathy. Read more in the summary.

Arterial hypertension

Clinical findings with rtx1 in hypertensive patients revealed modifications in the wall structure of retinal arterioles, which rtx1 enables quantifying with micron precision. Such alterations were correlated with microvascular changes in other parts of the body.

List of publications

Over 200 peer-reviewed research studies have used the rtx1 Adaptive Optics Retinal Camera to investigate retinal anatomy and pathology at the cellular and microvascular levels.
