Efficacy of different lighting schemes on refractive development and choroidal thickness in school-age children.

In 30 seconds

This randomized controlled trial examined the effects of a one-year high-illuminance crystal pure full-spectrum lighting scheme on refractive development in 198 school-aged children (6-10 years). The experimental group showed a significantly smaller increase in axial length and a more pronounced increase in choroidal thickness compared to the control group. The axial curvature ratio improved significantly in the experimental group (3.02 ± 0.07) versus the control group (p < 0.001).

Key findings

• The experimental group had a smaller increase in axial length compared to controls.
• Choroidal thickness increased significantly in the experimental group.
• The axial curvature ratio improved significantly in the experimental group (3.02 ± 0.07).
• Choriocapillaris flow deficit decreased significantly in the experimental group (13.11 ± 3.80%).

Why it matters

The findings suggest that specific lighting conditions in school settings may play a crucial role in managing refractive development in children, potentially aiding in myopia prevention strategies.
