High Resolution Imaging OCT Study

January 13, 2026 updated by: Heidelberg Engineering GmbH

High Resolution Imaging OCT Pilot Study

The goal of this pilot study is to compare image quality between the investigational devices (R1 and HighRes OCT) and the SPECTRALIS (cleared) in adult participants with normal and/or pathology eyes.

Participants will be imaged with different imaging modalities and scan protocols on all study devices.

Study Overview

Status

Status

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.

Enrollment (Estimated)

Enrollment

The number of participants in a clinical study. The "anticipated" enrollment is the target number of participants that the researchers need for the study.
97

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

  • Adult
  • Older Adult

Accepts Healthy Volunteers

Yes

  • Age-related macular degeneration Subjects with a diagnosis of AMD as determined by the investigator, either early-intermediate, atrophic, or neovascular
  • Diabetic retinopathy Subjects with a diagnosis of diabetic retinopathy as determined by the investigator
  • Disease with expected altered autofluorescence pattern Subjects with a disease that can be expected to be associated with altered autofluorescence patterns as determined by the investigator

Exclusion Criteria:

  • Subjects unable to read or write
  • Subjects with ocular media not sufficiently clear to obtain acceptable study-related imaging

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
cSLO Image quality grading
Time Frame: 6 months after image acquisition
Good: Good focus, even illumination, optimal exposure Average: The image is of sub-optimal quality, where there are issues with focus, illumination, or exposure, but the image still allows assessment of clinically relevant content Poor: Clinically relevant features are not visible, images are not clinically useful
6 months after image acquisition
Visability of key anatomical structures
Time Frame: 6 months after image acquisition

Visibility of

OCT image:

  1. Difference in reflectivity between the outer retino-choroidal complex and vitreous
  2. The vitreo-retinal interface
  3. Difference in reflectivity between retinal nerve fiber layer and vitreous
  4. Difference in reflectivity between plexiform layer and vitreous
  5. Multiple layers within the outer retino-choroidal complex
  6. The ganglion cell layer
  7. Difference in reflectivity between outer nuclear layer and vitreous
  8. External limiting membrane
  9. Choroidal/scleral interface

OCTA image:

  1. Foveal avascular zone
  2. Large vessels: 1st order vasculature, if applicable
  3. Medium vessels: 2nd and 3rd order vasculature
  4. Small vessels: between 3rd order vasculature and end capillaries
  5. End capillaries
6 months after image acquisition

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Safety Monitoring
Time Frame: from enrollment to study completion (expected 1 year after initiation)
