Risk Factors and Progression of Keratoconus
This study, taking place in France, aims to understand more about keratoconus, an eye condition where the cornea thins and bulges, causing blurry vision. Researchers will follow 200 people aged 10 to 40 for two years. Some participants will have eye treatments, like cross-linking surgery or getting special rings placed in their eye, while others will not have these treatments. The researchers want to see how the condition progresses naturally, how well different treatments work, and how changes in the eye are linked to changes in vision. They will collect information about the eyes and even test tears to learn more about the condition. This information could help improve future care for people with keratoconus.
Em resumo
Sobre o que é este estudo?
This study is designed to help us learn more about keratoconus, an eye condition that affects many people. When you have keratoconus, the clear front part of your eye, called the cornea, thins and bulges outwards like a cone. This can cause your vision to become blurry and distorted.
The main goal of this research is to closely observe and understand how keratoconus changes over a two-year period in 200 people. Some participants will receive standard treatments for keratoconus, such as cross-linking surgery (which helps strengthen the cornea) or having special rings placed inside the eye (to reshape it). Other participants will not have these specific treatments during the study period. By comparing these groups, doctors hope to gain a clearer picture of how the condition progresses and how different approaches might affect it.
Researchers will collect detailed information about participants' eyes, including how their vision changes and what the cornea looks like. They will also look at tiny proteins found in tears, as these might give clues about the condition. Understanding these links could help doctors in the future predict how keratoconus will develop and choose the best treatments for each person.
Pontos principais
- Learn about keratoconus progression over two years.
- Compares current treatments (cross-linking, rings) with no specific intervention.
- Includes participants aged 10-40 in France.
- Will collect detailed eye information, including tear analysis.
- Helps doctors better understand and treat keratoconus in the future.
Quem pode ser elegível?
To take part in this study, you would need to be between 10 and 40 years old. You also need to have keratoconus, whether it's clearly visible and affecting your vision, or if it's in an earlier stage where changes are just starting to show on eye scans, even if your vision is still good.
You should be receiving care for your eyes at one of three specific hospitals in France: CHU Montpellier, CHU Bordeaux, or CHU Toulouse. If you're an adult, you'll need to give your written permission to join after considering it carefully. If you're under 18, one of your parents or legal guardians must give their permission, and you'll also be asked to agree after thinking about it.
There are also a few reasons you might not be able to join. For example, if you're under legal guardianship, have had a corneal implant in both eyes before, or if you plan to move away before the initial part of the study is finished.
Este estudo pode ser adequado para você?
Responda a estas perguntas rápidas para ver se você pode ser elegível. Este é apenas um guia — a decisão final é da equipe de pesquisa.
- Are you between 10 and 40 years old?
- Do you have keratoconus (diagnosed or suspected)?
- Are you receiving eye care at CHU Montpellier, Bordeaux, or Toulouse?
- Are you able to provide consent (or a parent/guardian for minors)?
- Are you not planning to move before your initial treatment stage finishes?
O que envolve a participação?
If you decide to take part, the study will last for up to two and a half years. The visits and what happens during them will depend on whether you have surgery (like cross-linking or an intra corneal ring) or not.
If you don't have surgery, you'll have visits at 6 months, 12 months, and 24 months after starting the study. During these visits, doctors will check your eyes and vision. You'll also be advised not to rub your eyes, as this can worsen keratoconus.
If you do have surgery, your visits will be more frequent at the start: after 7 days, then at 1 month, 6 months, 12 months, and 24 months after your operation. At these appointments, doctors will closely monitor your recovery and how your eye is healing. This study only observes; no extra treatments outside of what your doctor would normally recommend will be given.
