Clinical evidence: RPE cells imaged with rtx1-TFI

In a study published in Diagnostics, clinical researchers at Quinze-Vingts National Eye Hospital, INSERM and University of Pittsburgh School of Medicine investigated the retinal pigmented epthelium with rtx1-TFI, an adaptive optics retinal camera with transscleral illumination.

 

They examined the same eyes with a method capable of revealing RPE cells – near-infrared autofluorescence AOSLO – and with the transscleral imaging modality of rtx1.

For the first time, the authors report cell-to-cell comparisons between TFI and NIRAF images. It provides clinical confirmation that rtx1-TFI enables assessing RPE cells.

 

“If we compare the time needed for capturing the same retinal area, rtx1-TFI is 35 times faster, which makes this system adapted to a clinical environment.”

 

 

To learn more, see also the interview with ophthalmologists Prof. Michel Paques, Prof. Kiyoko Gocho and Dr. Ysé Borella, who kindly shared their insight on how rtx1-TFI enables investigating pigment migration in dry AMD.

 

 

TFI is an optional add-on for the rtx1 AO retinal camera. It is available as an upgrade and is compatible with most existing rtx1 units.
