Clinical data from MERLIN to be presented at Euretina 2022/in Allgemein /by Marine Durand
At the Euretina 2022 annual meeting, in Hamburg on Sept 1-4, Dr Kiyoko Gocho will present more clinical results from the MERLIN project.
During the lecture, she will show multimodal information on the retina at different scales, including three-dimensional cellular-resolution images, all acquired with the MERLIN device in clinical settings. The series of clinical cases will cover a wide range of pathologies.

OCT reaches cellular resolution – MERLIN results got published/in Allgemein /by Marine Durand
We are happy to announce that the joint-article submitted by the entire MERLIN consortium has been published in Scientific Reports last week.
This paper covers more than 3 years of collaborative work for developing a novel retinal imaging instrument. As a peer-reviewed publication, it establishes the multi-modal and multi-scale retinal imaging capabilities of the Merlin device, and in particular, the applicability of cellular-level OCT imaging in clinical settings.
The H2020 MERLIN project is now closed, but the adventure still continues.
Imagine Eyes is further advancing the imaging device towards commercialization. Meanwhile, ophthalmologists at Paris Quinze-Vingts Hospital and Copenhagen Rigshospitalet implement MERLIN’s technology as a tool for accelerating the development of new therapies for sight-threatening retinal diseases. First clinical case reports were presented at ARVO 2022 (see previous news).

Clinical cases with MERLIN presented at ARVO 2022/in Allgemein /by Marine Durand
At the ARVO 2022 annual meeting, in Denver on May 2nd, Dr Kiyoko Gocho presented the first results of the pilot clinical investigation in the MERLIN project.
During the lecture, she showed extraordinary images that provided multimodal information on the retina at different scales, including three-dimensional cellular-resolution images, all acquired with the MERLIN device. The series of clinical cases covered a wide range of pathologies – inherited retinal diseases, AMD, diabetic retinopathy, serous detachment, arterial hypertension – demonstrating the applicability of the imaging device to clinical settings.

H2020 MERLIN project celebrates successful final review/in Allgemein /by Marine Durand
We are happy to announce the successful completion of our Horizon 2020 MERLIN project. We received a very positive evaluation from the European Commission last week after presenting the technical and clinical results of the new retinal imaging technology developed by MERLIN’s partners.
We take this opportunity to thank our advisors throughout the world for their extremely valuable contributions over the last 4 years. We are also grateful to the European Commission for supporting MERLIN and to reviewers for their constructive feedback.
The project has delivered retinal imaging prototypes that are now being tested at two medical centers. These systems combine several technologies, including optical coherence tomography OCT) and adaptive optics (AO), to visualize the retina at different scales with multiple modalities. For the first time, doctors can directly examine cells in three dimensions at the back of the eye.
After MERLIN, the adventure continues.
Imagine Eyes is further advancing the imaging device towards commercialization. Meanwhile, for ophthalmologists at Paris Quinze-Vingts Hospital and Copenhagen Rigshospitalet, the next step is to implement MERLIN’s technology as a tool for accelerating the development of new therapies for sight-threatening retinal diseases.
Beyond ophthalmology, the SHIVA project is poised to explore applications in neurology. To do so, SHIVA partners will further develop MERLIN’s-OCT angiography technology and investigate retinal microcirculation in dementia and cognitive decline with an unprecedented level of detail. The goal is to better prevent and treat major causes of neurological disability.
MERLIN results to be presented at ICOOR 2021/in Allgemein /by Marine Durand
The 9th International Congress on OCT and OCT Angiography – ICOOR 2021 meeting – will be held in Rome on Dec 17-18.
Michael Pircher and Nicolas Chateau will present MERLIN project outcomes. Their lectures will introduce the clinical-prototype developed by the consortium, which delivers multimodal information on the retina at different scales, including three-dimensional cellular-resolution images.

More than 170 subjects examined with MERLIN/in Allgemein /by Marine Durand
MERLIN clincial protoypes were installed at Quinze-Vingts National Eye Hospital in Paris in December 2020, and Rigshopitaltet in Copenhagen in January 2021. Since then, clinicians have used it to examine the back of the eye of 177 subjects.
The performance of the device, in terms of image quality and ergonomy, was confirmed on 35 healthy volunteers as well as 142 patients with various pathologies : age-related macular degeneration, inherited retinal diseases, diabetes, hypertension, and other retinal diseases.
In these patients, MERLIN images provided unprecedented details of retinal changes – at the level of single photoreceptor cells and capillary blood vessels.

MERLIN project implements active retinal tracking/in Allgemein /by Marine Durand
The MERLIN team recently integrated a new active retinal tracking technology (ARTT) in several multimodal retinal imaging prototypes.
During retinal examinations, the natural movements of patients’ eyes have detrimental effects on the quality of retinal images. Distortion artifacts induced by eye motion are particularly pronounced in tomographic scans acquired with a high optical magnification. The purpose of ARTT is to neutralize these effects.
With MERLIN’s ARTT, the position of the laser beam that scans the retina is continuously corrected for any movement of the eye. This active compensation is driven by fast measurements of retinal displacements using a secondary laser beam. As a result, the system delivers high-magnification tomographic images without motion distortion (see image below).
Two MERLIN prototypes equipped with the new ARTT are now under clinical testing at Paris Quinze-Vingts Hospital and Copenhagen Rigshospitalet.
