Trial summary

Retinopathy pigmentosa (which affects about 40,000 patients in France) leads to destruction of the peripheral retina. This condition, often familial, frequently affects young patients. Visual acuity is excellent for a long time, the disease affecting the central macular region only belatedly. Read more about this study

About this study

Official title: Evaluation of the Visual Field on the Ground: Impact on Locomotion Rehabilitation Adults With Retinitis Pigmentosa With Loss of Peripheral Vision

Retinopathy pigmentosa (which affects about 40,000 patients in France) leads to destruction of the peripheral retina. This condition, often familial, frequently affects young patients. Visual acuity is excellent for a long time, the disease affecting the central macular region only belatedly. On the other hand, the visual field is very quickly narrowed to a central or paracentral zone.

For the patient, knowing the limits of his visual field and learning to adapt is necessary especially when traveling.

The management of these patients is twofold:

  • an orthoptist carries out an overall evaluation of the visual field using the Goldmann device (30 cm projection of the areas seen and not seen by the patient's eye), then performs rehabilitation over several weeks
  • an instructor of locomotion (open specialization: occupational therapist, case of this project,...) carries out an evaluation in situation, followed by a personalized reeducation over several weeks. The first sessions consist in establishing a climate of confidence, presenting the objectives of the management of locomotion and begin to understand the movements inside and outside accompanied. The following of the rehabilitation is an apprenticeship of the optimal use of the residual field of vision and the proposed technical aids (white cane), in the whole of the displacements, inside and outside.

The residual field of vision is evaluated by a device at the first appointment at the specialized center. This examination, necessary for the professional, is not informative for the patient. It is sometimes supplemented by the evaluation of the visual field of view (ECVS). The ECVS, done jointly by the orthoptist and the locomotion instructor, consists in evaluating the functional visual field on a horizontal plane at 1m (meter) and 5m, and vertical at 5m. The field of vision of the patient, immobile, is materialized by targets deposited at each limit of the zones seen that it indicates.

The investigators believe that the passing of a visual field on the ground, thanks to the projection of the zones of vision, allows the patient to improve his knowledge on his visual possibilities (and gaps) and thus to make his reeducation more efficient.

What is being measured

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

  1. difference in the number of errors committed during a walk between T0 and T2

    difference in the number of errors committed (= number of hurdles, number of "doors" forgotten) during a walk between T0 (before ECVS) and T2 (after ECVS + 10 re-education sessions).

    Measured: 2 months

Questions about this trial

What is this clinical trial studying?

A study testing evaluation of the visual field on the ground in people with Retinitis Pigmentosa Syndrome, run by University Hospital, Limoges.

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 7 inclusion and 7 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 9 Jun 2026. 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?

difference in the number of errors committed during a walk between T0 and T2 (time frame: 2 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 9 Jun 2026.
