Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Prospective, longitudinal, interventional, exploratory, non-randomized, single-center study including patients with pathological myopia .

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

This project will be conducted in two phases, with a qualitative study and an exploratory phase.

There is a clinical need to better understand the progression of myopic complications with diffuse choroidal atrophy (DCA Cat. 2) and choroidal patch atrophy (CPA Cat. 3) and their impact on everyday life.

The first phase is a qualitative study whose objectives are

1. to study the parameters (ceiling and floor effects) and assess the reliability of performance tasks in relation to perceived difficulties,
2. to use interviews to gather information on the difficulties reported in everyday life, the causes, and the environmental conditions leading to a reduction in activity in a population of myopic patients with retinal complications.

The second phase will consist of a quantitative exploratory pilot study aimed at comparing the performance of diffuse choroidal atrophy (DCA) and choroidal patch atrophy (CPA) patients in order to highlight any differences between the two in tasks involving mobility and obstacle avoidance, visual search, and driving

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Qualitative Phase

The "Qualitative" phase, estimated to last six months, will be conducted on a panel of up to 30 patients with hight myopia for the purpose of conducting semi-structured interviews and pre-tests to calibrate the Perf Outcome parameters.

Group Type OTHER

Quality of life questionnaire

Intervention Type OTHER

The NEI-RQL-42 (National Eye Institute Refractive Quality of Life) questionnaire will be self-administered via a secure online platform to assess the impact of pathological myopia on quality of life.

Performance Outcomes (PerfO)

Intervention Type OTHER

Three tests are planned to assess the impact of high myopia on critical aspects of mobility and safety, with the possibility of adjusting their scope based on pilot data.

* The first test involves an assessment of driving on a simulator, designed to evaluate the performance of detecting pedestrians in peripheral vision, with and without glare.
* The second test focuses on assessing mobility and obstacle avoidance under six levels of brightness.
* The third test evaluates visual search ability. It consists of finding spheres in everyday scenes in an apartment with six levels of contrast tested.

Semi-structured interviews

Intervention Type OTHER

Semi-structured interviews will only be offered to patients recruited in Phase 1 Qualitative and aim to further explore the information gathered from the NEI-RQL-42 questionnaire responses and the difficulties encountered during the performance tasks in the laboratory, by exploring in more detail the limitations encountered by patients with pathological myopia in their daily activities. These interviews will help identify the specific causes of the difficulties encountered, as well as the environmental conditions that may create discomfort or increased hardship.

Exploratory Phase

The "Exploratory" phase, estimated to last 18 months, will be conducted on a panel of 70 patients with hight myopia in order to explore the validity of Perf Outcome.
