Study Overview

Status

Status

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

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.

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

  • Child
  • Adult
  • Older Adult

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Description

  • Exclusion Criteria:

    • Any patient who has a cloudy cornea.
    • Any patient whose RetCam imaging exam easily produces blanching of the optic nerve in the normal course of imaging.
    • Any patient who has consented to the procedure, but whose course of examination has filled the time allotted, leaving no time to evaluate the COSMOS.

  • Inclusion Criteria:

    • Current patients undergoing clinically indicated EUA and RetCam imaging for surveillance and treatment of ophthalmic conditions at The Hospital for Sick Children.

Study Plan

This section provides details of the study plan, including how the study is designed and what the study is measuring.

  • Primary Purpose: Diagnostic
  • Allocation: N/A
  • Interventional Model: Single Group Assignment
  • Masking: None (Open Label)

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
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.
Experimental: PCI imaging system
Procedure: Examination under anaesthetic (EUA)
The EUA is scheduled as part of the routine clinical management of children with various ophthalmic conditions.
Device: RetCam
The RetCam is a pediatric wide-field retinal camera that has been the mainstay for pediatric ophthalmic imaging since 1997. Imaging using the RetCam (during the EUA) is conducted as part of routine clinical magagement.
Device: COSMOS
The COSMOS images will be captured (during the EUA) after the RetCam images. The COSMOS is designed to be used in the same way as the RetCam, but to produce higher quality images.

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
Comparison of the field of view in RetCam and COSMOS images
Time Frame: 1 day
Masked investigators will review images from the RetCam and the COSMOS. Field of view will be graded on a scale from 1-5, with 1 being the worst and 5 being the best. We will test for significant difference, at alpha level 0.05, between scores of the images taken by the RetCam and the COSMOS.
1 day
Comparison of the color in RetCam and COSMOS images
Time Frame: 1 day
Masked investigators will review images from the RetCam and the COSMOS. Color will be graded on a scale from 1-5, with 1 being the worst and 5 being the best. We will test for significant difference, at alpha level 0.05, between scores of the images taken by the RetCam and the COSMOS.
1 day
Comparison of the dynamic range in RetCam and COSMOS images
Time Frame: 1 day
Masked investigators will review images from the RetCam and the COSMOS. Dynamic range will be graded on a scale from 1-5, with 1 being the worst and 5 being the best. We will test for significant difference, at alpha level 0.05, between scores of the images taken by the RetCam and the COSMOS.
1 day
Comparison of the sharpness in RetCam and COSMOS images
Time Frame: 1 day
Masked investigators will compare images from the RetCam and the COSMOS and grade sharpness on a scale from 1-5, with 1 being the worst and 5 being the best. We will test for significant difference, at alpha level 0.05, between scores of the images taken by the RetCam and the COSMOS.
1 day
Comparison of the detail in RetCam and COSMOS images
Time Frame: 1 day
Masked investigators will review images from the RetCam and the COSMOS. Detail will be graded on a scale from 1-5, with 1 being the worst and 5 being the best. We will test for significant difference, at alpha level 0.05, between scores of the images taken by the RetCam and the COSMOS.
1 day
Comparison of the resolution in RetCam and COSMOS images
Time Frame: 1 day
Masked investigators will review images from the RetCam and the COSMOS. Resolution will be graded on a scale from 1-5, with 1 being the worst and 5 being the best. We will test for significant difference, at alpha level 0.05, between scores of the images taken by the RetCam and the COSMOS.
1 day
Comparison of the evenness of illumination in RetCam and COSMOS images
Time Frame: 1 day
Masked investigators will review images from the RetCam and the COSMOS. Evenness of illumination will be graded on a scale from 1-5, with 1 being the worst and 5 being the best. We will test for significant difference, at alpha level 0.05, between scores of the images taken by the RetCam and the COSMOS.
