Moorfields Eye Hospital, clinical partner of the IMCUSTOMEYE consortium, has published a post about the IMCUSTOMEYE project on their intranet and newsletter. The post introduce the project and talks about the Moorfields’ role testing patients with keratoconus, cataract and glaucoma to validate the new devices’ ability to identify corneal disease and measure eye pressure accurately.

Moorfields Eye Hospital is the leading provider of eye health services in the UK and a world-class centre of excellence for ophthalmic research and education. The main focus of their 2300 staff members is the treatment and care of NHS patients with a wide range of eye problems. The volume and variety of conditions treated by Moorfields clinicians means that they have a unique range of skills and knowledge.

The next step in the project for Moorfields will be to set up the study mentioned before and then begin recruiting patients from clinics to take part in the testing.

Imcustomeye press release published by the university of liverpool

The University of Liverpool, member of the IMCUSTOMEYE consortium, has published a press release on the project in its research section. The article highlights the role of the University’s Biomechanical Engineering Group in the development of new imaging techniques to diagnose and treat corneal diseases and glaucoma in a personalised manner. 

Professor Ahmed Elsheikh, head of the research group, explains that “despite the fact that these treatments, and the conditions they help with, interact or interfere mechanically with the cornea, there is currently no method to accurately measure corneal biomechanical properties in vivo. Such a method would be essential for customising these treatments for individual patients’ needs and ultimately improving their clinical outcomes. The IMCUSTOMEYE project is intended to address this need,”

IMCUSTOMEYE landmark paper on first multi-meridian corneal imaging device PUBLISHED IN BOE

10/16/2020

 
Picture
An EU Horizon 2020 IMCUSTOMEYE project landmark paper has just been published in Biomedical Optics Express. It is the result of a collaboration between CSIC, University of Liverpool, and the Polish Academy of Science. It presents the first multi-meridian corneal imaging device, based on a swept-source optical coherence tomography system with high transverse scanning frame rates, to measure a promising early keratoconus biomarker based on air-puff-induced deformation asymmetry. The system will serve both as the basis for determining the minimum viable specifications for a keratoconus screening device based on a deformation asymmetry biomarker, and as a platform to estimate patient-specific corneal biomechanical properties, that can be fed in corneal surgery planning simulators. Currently the system is employed in a pilot clinical study with Keratoconus and Lasik-candidate subjects in collaboration with Fernandez Vega Ophthalmological Institute.

All partners, including the PIs, attended the two days meeting, gaving an update on the research, IP and outreach progress of the project during this past year. Professor Cynthia Roberts (Department of Biomedical Engineering, Ohio State University), member of the Advisory Board, was invited to the meeting where she gave a lecture on "The importance of corneal biomechanics as a diagnostic marker". 

The event also included bilateral discussions on specifics of the project between designated partners, a steering committee session and a debate on the impact of COVID-19 on market of medical devices and clinical studies. 

New Publications on Nanosensitive OCT acknowledging Imcustomeye

Optical coherence tomography (OCT) is a non-invasive depth resolved optical imaging modality, that enables high resolution, cross-sectional imaging in biological tissues and materials at clinically relevant depths. Though OCT offers high resolution imaging, the best ultra-high-resolution OCT systems are limited to imaging structural changes with a resolution of one micron on a single B-scan within very limited depth. Nanosensitive OCT (nsOCT) is a recently developed technique that is capable of providing enhanced sensitivity of OCT to structural changes. Improving the sensitivity of OCT to detect structural changes at the nanoscale level, to a depth typical for conventional OCT, could potentially improve the diagnostic capability of OCT in medical applications. Researchers from the National University of Ireland Galway demonstrates in this paper, published by Biomedical Optics Express, the capability of nsOCT to detect structural changes deep in the rat cornea following superficial corneal injury.

Corneal cross‐linking (CXL) using ultraviolet‐A (UVA) irradiation with a riboflavin photosensitizer has grown from an interesting concept to a practical clinical treatment for corneal ectatic diseases globally, such as keratoconus. This research led by NUI Galway reports the application of oversampling nanosensitive OCT for probing the corneal structural alterations. The results indicate that the spatial period increases slightly after 30 minutes riboflavin instillation but decreases significantly after 30 minutes UVA irradiation following the Dresden protocol. The proposed noninvasive method can be implemented using existing OCT systems, without any additional components, for detecting nanoscale changes with the potential to assist diagnostic assessment during CXL treatment, and possibly to be a real‐time monitoring tool in clinics.

Most of the fundamental pathological processes in living tissues exhibit changes at the nanoscale. Noninvasive, label-free detection of structural changes in biological samples pose a significant challenge to both researchers and healthcare professionals. Modern nanoscopy largely requires labeling, is limited to superficial 2D imaging, and is generally not suitable for in vivo applications. In this article published in Applied Physics Letters, we presented a method, spatial frequency domain correlation mapping optical coherence tomography (sf-cmOCT), developed at NUI Galway, for detection of depth resolved nanoscale structural changes noninvasively. Our approach is based on detection and correlation of the depth resolved spectra of axial spatial frequencies of the object which are extremely sensitive to structural alterations. These experimental results demonstrate possibilities for the study of nanoscale structural changes, without the need for biomarkers or labels. Thus, sf-cmOCT offers exciting and far-reaching opportunities for early disease diagnosis and treatment response monitoring, as well as a myriad of applications for researchers.

One option for treating keratoconus, a degenerative disease that results in a weakened cornea and vision loss, is cross-linking. Cross-linking strengthens the overall structure of the cornea by promoting the creation of covalent bonds between neighboring collagen fibrils or between fibrils and the surrounding extracellular matrix. To measure how cross-linking affects the cornea at different depths inside the stroma, three different corneal treatments were performed on rabbit animal models: no treatment, Riboflavin instillation/Ultraviolet irradiation, and Rose Bengal instillation/Green light irradiation. Rabbits were sacrificed one and two months after treatment. Images of corneal lamellae were taken with a second harmonic generation laser scanning microscopic developed at VioBio Lab (CSIC) and were analyzed with a MATLAB script to measure the different directions of the collagen fibers. The collagen fibers in the cross-linked corneas had more uniform fiber orientations than in untreated corneas through a depth of 300 microns. The amount of second harmonic generation is also greater in cross-linked corneas than in control corneas. Both the organization and second harmonic generation signal increased between one month and two months after treatment. This research was a collaboration between CSIC, the University of Valladolid, and the Wellman Center for Photomedicine.

​Application of the air‐puff swept source optical coherence tomography (SS‐OCT) instrument to determine the influence of viscoelasticity on the relation between overall the air‐puff force and corneal apex displacement of porcine corneas ex vivo has been demonstrated. Micrometer resolution, fast acquisition and noncontact character of the air‐puff SS‐OCT measurements have potential to improve the in vivo assessment of mechanical properties of the human corneas. This work was successfully published in Journal of Biophotonics.
