Topcon 3D OCT-1 Maestro Reference Database Study II

June 6, 2022 updated by: Topcon Medical Systems, Inc.
The objective of this study is to collect OCT measurement data on normal healthy eyes in order to determine the reference limits for Topcon 3D OCT-1 Maestro based on the percentile points for 1%, 5%, 95%, and 99%.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

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

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

18 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Sampling Method

Non-Probability Sample

Study Population

Subjects without eye disease

Description

Inclusion Criteria for Normal Group

  1. Subjects 18 years of age or older on the date of informed consent
  2. Subjects able to understand the written informed consent and willing to participate as evidenced by signing the informed consent
  3. Subjects presenting at the site with normal eyes (eyes without pathology)
  4. lOP <= 21 mmHg bilaterally
  5. BCVA 20/40 or better (each eye)
  6. Both eyes must be free of eye disease

Exclusion Criteria for Normal Group

  1. Subjects previously enrolled in either the Maestro AP study or the Maestro2 study
  2. Subjects unable to tolerate ophthalmic imaging
  3. Subject with ocular media not sufficiently clear to obtain acceptable OCT images
  4. HFA visual field (24-2 Sita Standard, white on white) result unreliable (based on manufacturer's recommendation), defined as fixation losses > 20% or false positives> 33%, or false negatives> 33%

  5. Visual field defects consistent with glaucomatous optic nerve damage based on with at least one of the following two findings:

    • On pattern deviation (PD), there exists a cluster of 3 or more points in an expected location of the visual field depressed below the 5% level, at least 1 of which is depressed below the 1% level;
    • Glaucoma hemi-field test "outside normal limits."
  6. Presence of any ocular pathology except for cataract
  7. Narrow angle
  8. History of leukemia, dementia or multiple sclerosis
  9. Concomitant use of hydroxychloroquine and chloroquine

Study Major Dates

Study Start

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.
May 1, 2015

Primary Completion (Actual)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.

Study Completion (Actual)

Study Completion

The date on which the last participant in a clinical study was examined or received an intervention/treatment to collect final data for the primary outcome measures, secondary outcome measures, and adverse events (that is, the last participant's last visit). The "anticipated" study completion date is the date that the researchers think will be the study completion date.
