Trial summary

The transient visual disturbances (TVD) are defined by a short abnormality of visual function. Their etiology may be ophthalmological, neurological non-ischemic or of ischemic origin. The difficulty is to recognize an ischemic mechanism which imposes emergency cares. Read more about this study

About this study

Official title: Development and Validation of a Predictive Score for the Ischemic Etiology of a Transient Visual Disturbances

The transient visual disturbances (TVD) are defined by a short abnormality of visual function. Their etiology may be ophthalmological, neurological non-ischemic or of ischemic origin.

The difficulty is to recognize an ischemic mechanism which imposes emergency cares.

A clinical score could help the clinician to recognize the etiology of the TVD .

Being tested
Clinical, ophthalmological and neurological evaluation

What is being measured

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

  1. Etiology, ischemic or not, of the initial transient visual disturbance

    Clinical : questionnaire about the symptoms and about the vascular risk factors Cerebral MRI, MRI angiography of the supra-aortic trunks, ECG, Holter, transthoracic echocardiography, blood count, erythrocytes sedimentation rate, C reactive protein, visual field, optical coherence tomography, retinography and a new evaluation after 3 months.

    Measured: 3 months

Secondary outcomes (4)
  1. Incidence of new visual transient ischemic attacks during the 3 months of follow-up

    Clinical : questionnaire about the symptoms and about the vascular risk factors Cerebral MRI, MRI angiography of the supra-aortic trunks, ECG, Holter, transthoracic echocardiography, blood count, erythrocytes sedimentation rate, C reactive protein, visual field, optical coherence tomography, retinography and a new evaluation after 3 months.

    Measured: 3 months

  2. Incidence of visual ischemic strokes during the 3 months of follow-up

    Clinical : questionnaire about the symptoms and about the vascular risk factors Cerebral MRI, MRI angiography of the supra-aortic trunks, ECG, Holter, transthoracic echocardiography, blood count, erythrocytes sedimentation rate, C reactive protein, visual field, optical coherence tomography, retinography and a new evaluation after 3 months.

    Measured: 3 months

  3. Incidence of transient ischemic attacks, visual or not visual, during the 3 months of follow-up

    Clinical : questionnaire about the symptoms and about the vascular risk factors Cerebral MRI, MRI angiography of the supra-aortic trunks, ECG, Holter, transthoracic echocardiography, blood count, erythrocytes sedimentation rate, C reactive protein, visual field, optical coherence tomography, retinography and a new evaluation after 3 months.

    Measured: 3 months

  4. Incidence of ischemic strokes, visual or not visual, during the 3 months of follow-up

    Clinical : questionnaire about the symptoms and about the vascular risk factors Cerebral MRI, MRI angiography of the supra-aortic trunks, ECG, Holter, transthoracic echocardiography, blood count, erythrocytes sedimentation rate, C reactive protein, visual field, optical coherence tomography, retinography and a new evaluation after 3 months.

Questions about this trial

What is this clinical trial studying?

An observational study of Vision Disorders, run by Fondation Ophtalmologique Adolphe de Rothschild at 2 sites in France.

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 1 inclusion and 1 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: finished, as of the sponsor's last update on 25 Mar 2019. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 2 sites in France. Whether a site is taking part right now should be confirmed with that site. See every site.

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 is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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?

Etiology, ischemic or not, of the initial transient visual disturbance (time frame: 3 months). 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 25 Mar 2019.
