JOURNAL ARTICLE
Kah Hie Wong, Meng Hsien Yong, Safinaz Mohd Khialdin, Wan Haslina Wan Abdul Halim
SIGNIFICANCE: Determining the anatomic location of insult in cases of concurrent bilateral upgaze palsy with bilateral ptosis can be challenging due to the various overlapping pathways and shared functions. It is more commonly related to bilateral oculomotor nerve palsies and myasthenia gravis. However, the possibility of unilateral cerebrovascular events may be overlooked due to the lack of laterality of disease manifestations. PURPOSE: This report documents the uncommon presentation of bilateral ptosis and upgaze palsy in unilateral hemispheric hemorrhage with the corresponding clinical and anatomical review...

Exposure to long-wavelength light has been proposed as a potential intervention to slow myopia progression in children. This article provides an evidence-based review of the safety and myopia control efficacy of red light and discusses the potential mechanisms by which red light may work to slow childhood myopia progression.The spectral composition of the ambient light in the visual environment has powerful effects on eye growth and refractive development. Studies in mammalian and primate animal models (macaque monkeys and tree shrews) have shown that daily exposure to long wavelength (red or amber) light promotes slower eye growth and hyperopia development and inhibits myopia induced by form deprivation or minus lens wear...
