Daily morning light therapy is associated with an increase in choroidal thickness in healthy young adults. – School of Optometry and Vision Science, Queensland University of Technology. – Read, S. A., Pieterse, E. C., Alonso-Caneiro, D., Bormann, R., Hong, S., Lo, C. H., Richer, R., Syed, A., & Tran, L. (2018).

Objective This study aimed to examine the influence of morning bright light therapy upon choroidal thickness in healthy young adults. Studies have demonstrated that choroidal thinning accompanies the development and progression of myopia (Read, S., Fuss, J., Vincent, S., Collins, M., & Alonso‐Caneiro, D. (2018). Choroidal changes in human myopia: insights from optical coherence tomography […]
