Trial summary

This study is aimed at creation and validation of a vitreous haze scoring system using ultrasonography B-scan of the eye. Images will be obtained from patients with uveitis and quantification of inflammation will be done to create the scoring scale. Read more about this study

About this study

This study is aimed at creation and validation of a vitreous haze scoring system using ultrasonography B-scan of the eye. Images will be obtained from patients with uveitis and quantification of inflammation will be done to create the scoring scale.

Read the detailed description

Patients with uveitis may present with Vitreous Haze (VH) resulting in obscuration of fundus details. VH is composed of cells and protein exudation and results in decrease visual acuity.The degree of VH is an important indicator of disease activity, severity and response to therapy in patients with uveitis. Color fundus images are commonly used to objectively document VH.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Ultrasonography B-scanDevice

    The patient's eye will be anesthetized. The ultrasound probe will then be used to obtain images by keeping the probe in light contact with the eye.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Inter-observer correlation for vitreous haze grading

    Inter-observer correlation for vitreous haze (VH) grading will be assessed using number of eyes as the unit of measure as well as standardized grading scheme for VH

    Measured: 1 year

Questions about this trial

What is this clinical trial studying?

A study testing Ultrasonography B-scan in people with Uveitis, run by University of Nebraska.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 3 inclusion and 5 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: withdrawn, as of the sponsor's last update on 15 Aug 2023. Status can change between updates, so confirm with the study contact before making plans.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study was withdrawn before enrolling participants, so there are no results.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Inter-observer correlation for vitreous haze grading (time frame: 1 year). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 15 Aug 2023.
