What is the purpose of this trial?

This trial aims to determine if riboflavin (Vitamin B2) and daily sunlight can slow the progression of nearsightedness in children. The trial will assess whether different doses of riboflavin combined with outdoor play are more effective than no riboflavin. Children diagnosed with myopia and mild astigmatism may be suitable candidates. Participants will be divided into groups to receive either 400 mg, 200 mg, or no riboflavin while playing outside for 30 minutes daily over six months. As a Phase 2 trial, this research focuses on evaluating the treatment's effectiveness in an initial, smaller group.

Will I have to stop taking my current medications?

The trial information does not specify whether participants need to stop taking their current medications.

Is there any evidence suggesting that this trial's treatments are likely to be safe?

Research shows that riboflavin, also known as Vitamin B2, is generally safe for use. The FDA has labeled it as "generally recognized as safe" (GRAS), indicating it is safe to consume in the amounts typically found in foods or supplements.

Studies have not reported any serious side effects. Most reports mention only mild issues, such as a change in urine color, which is harmless and expected. In studies for other conditions, riboflavin did not cause any major problems.

Since this trial is in an early stage, the researchers are primarily focusing on safety. They believe riboflavin is well-tolerated, but further studies will help clarify its safety for this specific use.12345

Why are researchers excited about this trial's treatments?

Researchers are excited about the use of riboflavin, or vitamin B2, for managing myopia in children because it offers a novel approach compared to the usual methods like corrective lenses or atropine eye drops. Unlike typical treatments that focus on symptom management, riboflavin might address the progression of myopia by potentially strengthening the eye's connective tissues through its role in energy production and repair processes. Additionally, combining riboflavin with outdoor sunlight exposure could harness natural light's benefits in slowing myopia progression, offering a holistic and non-invasive strategy. This treatment could be particularly appealing due to its simplicity and the added health benefits of increased outdoor activity.

What evidence suggests that riboflavin might be an effective treatment for preventing myopia progression?

Research has shown that riboflavin, or Vitamin B2, might improve eye health when combined with sunlight. Early studies on conditions like keratoconus, where the cornea becomes thin and cone-shaped, suggest that taking riboflavin and spending time in the sun can help prevent further eye problems. In this trial, participants will receive different doses of riboflavin: one group will take 400 mg daily, another group will take 200 mg daily, and a placebo group will receive 0 mg. Specifically, one study found that people who took 400 mg of riboflavin daily and got sun exposure saw their eye condition stabilize or improve. These findings are encouraging for using riboflavin to possibly slow the worsening of nearsightedness (myopia) in children.678910

Published Research Related to This Trial

A study involving 100 eyes from 61 patients with progressive keratoconus found that both 0.1% riboflavin solutions used in corneal collagen crosslinking (CXL) were equally safe and effective, with no significant differences in visual and corneal measurements after 12 months.
No serious complications occurred in either group during or after the procedure, indicating that both riboflavin solutions can be safely used for treating keratoconus.
