Would you like to have all retreatment parameters at a glance when you see your patients with neovascular AMD?

The RetInSight Fluid Monitor provides a concise PDF report by a mouse click:


• Fluid compartments, volume, fluctuations between visits, distribution and thickness together with the original and annotated images of the central OCT scan; all retreatment parameters at one glance.


• Time saved by avoiding the need to look up and review images and/or data from the previous visit.


• May be used as a patient hand-out, to create transparency and improve compliance.


• While Fluid Monitor processes the images of patient A, the images of patient B can be taken (no idle time).

Then take the next evolutionary step in the management of nAMD with theRetInSight Fluid Monitor

An updated comprehensive version of Fluid Monitor is available from February 27, 2023, for the monitoring of patients with neovascular age-related macular degeneration (nAMD).


In addition to precise fluid volume measurements using routine OCT images, the novel Fluid Monitor also provides the fluid volume changes compared to the previous visit. Fluctuations are indicative of decreased or increased disease activity, which guides retreatment decisions.


The RetInSight Fluid Monitor fulfills all MDR 2017/745 requirements for class IIa medical devices as a Clinical Decision Support System (CDSS) and may be used in clinical routine in the EU.


It is intended to be compatible with all leading OCT systems, starting with the Heidelberg Engineering SPECTRALIS® OCT/Heyex/AppWay platform.

The RetInSight Fluid Monitor is a unique CE-certified AI-based fluid activity meter

The accumulation of fluid in the retina can be observed in OCT-images as reliable indicator of disease activity.1


The RetInSight Fluid Monitor is an AI-based fluid activity meter for the monitoring of disease progression and treatment response in patients with nAMD.


It supports the optimisation and personalisation of therapy, with the aim to improve patient outcomes and enhances workflow to increase clinical efficiency and reduce cost.


The concise Fluid Monitor report can be generated by the OCT-operator under the supervision of the eye care specialist in just a few minutes, while the patient is on site.

The RetInSight Fluid Monitor identifies, localizes, and quantifies retinal fluid by assigning a label to each OCT pixel in an entire OCT volume.

It denotes its fluid type as intraretinal fluid (IRF), subretinal fluid (SRF) or pigment epithelial detachment (PED) when present, as well as its location within the central 1-mm and 6-mm macular area.

And converts the automated segmentations into precise volumes in nanoliters.2,3

And easy to interpret fluid volume changes

The RetInSight Fluid Monitor provides fluid volume changes compared to the previous visit, which are clinically relevant:

Greater fluctuations in retinal fluid volumes during the maintenance phase of anti-VEGF treatment in nAMD is associated with worse VA by 2 years. 4

Most relevant for an optimized fluid management is a precise assessment of fluid dynamics to distinguish stable from recurrent SRF and novel from persistent, IRF i.e., degenerative, IRF, which is enabled by the accuracy of AI-based fluid measurement in nl. 5

By fluid compartment

IRF, SRF and PED compartments have a different impact on visual function and show a different fluid resolution during therapy:

Intraretinal fluid was the only variable that reflected VA increase and decrease over time. 3

To optimally manage nAMD, clinicians should understand the impact of fluid compartments on visual acuity. After initial treatment, anti-vascular endothelial growth factor regimens that tolerate stable subretinal fluid (if visual acuity is stable/improved) but not intraretinal fluid may enable patients to achieve their best possible visual acuity. 6

This study suggests that levels of SRF up to around 150 lm thickness on OCT have minimal impact on vision. Greater levels of SRF have greater impact on vision, unless associated with significant amounts of atrophy or SHRM, when the additional effect of the SRF on vision remains low. 7

The most relevant biomarker for BCVA was the horizontal extension of IRF in the foveal region, whereas SRF and PED ranked low. 8

86% of responders considered the development of subretinal and/or intraretinal fluid on the OCT as a reason to initiate anti-VEGF therapy in a patient with wet AMD. 9

With highly reliable and consistent accuracy

The volume measurement accuracy of the RetInSight Fluid Monitor is comparable to the manual reading by expert-readers and the reported automated measurements in the literature.10

The Fluid Monitor measurements are objective and consistent, unlike manual reading:

Our findings highlight the variability in the performance of human expert OCT grading and the need for AI-based automated feature analyses.11

Unprecedented speed

On average, the manual annotation of an OCT volume of 97 B-scans by an experienced expert-reader takes 2 hours and 49 minutes.

The RetInSight Fluid Monitor requires only 2 minutes and 8 seconds. The entire Fluid Monitor processing, from the receipt of the OCT image up to the generation of the report, takes on average 3 minutes and 6 seconds (excluding variable up- and download time).10

An opportunity to save time during clinical routine and improve patient throughput without compromise on patient safety.

Which potential value does the RetInSight Fluid Monitor bring?

Eye Care Specialists

• A solid basis for confident treatment decisions

• The possibility to document the new hard data points facilitates long-term monitoring

• The ability to optimise and personalise treatment regimens, thereby reducing the risk and deficiencies of over- and under-treatment 2-11

• A more efficient workflow, resulting in higher patient throughput

​

72% of responders believed that artificial intelligence will significantly assist their ability to diagnose and monitor  retina diseases in the next 2-3 years. 75% said would use AI-based healthcare tools in their practice, on a case-by-case basis.9

Payer

• Gaining better insight into the budget spent on nAMD and improving resource allocation

• Reducing the cost per patient, which, combined with a better patient flow and throughput, results in enhanced patient access 

Patients

• Shorter waiting times before getting an appointment with and seeing the eye care specialist

• Less inconvenience and lower cost associated with travel and absence from work caused by over-treatment, and reduced risk of vision loss caused by under-treatment

• Increased trust and compliance with the therapy, resulting from receiving an understandable personal Fluid Monitor report as evidence of disease progression and treatment response​

Hospitals and Clinics

An opportunity to finetune internal treatment protocols, demonstrate quality of care and strengthen the reputation as innovative eye care provider, becoming or remaining:​

• An attractive and competitive workplace for the AI-generation

• A preferred eye care provider for patients and referring general practitioners

• A valuable partner to insurance companies and/or Ministries of Health

About the Fluid Monitor logo​

The RetInSight Fluid Monitor is an AI-based software solution for the detection, localisation and quantification of intraretinal (IRF), subretinal (SRF) and pigment epithelial detachment-related (PED) fluid at an ultrastructural level. This is expressed by the product logos and program icons.

The symbol​

The symbol shows in a graphically abstracted but medically correct way a typical OCT image for retinal fluid. The curved baseline represents the retina; the three ovals represent the fluid compartments embedded in the retinal layers. The waveform indicates the recurrence of fluid, the so-called fluctuations (fluid activity), over the course of the chronic progressive disease.​

The shape​

The basic form of the Fluid Monitor icon is the square. It stands for the therapeutic monitoring. ​

The superscript company logo acts as the sender: Fluid Monitor is a product of RetInSight.

The color​

The basic color dark blue was chosen as an objective, calm and analytical color and one that is associated with trust, honesty and reliability.​
