The Claim
In a cohort of 1256 children followed from birth to age 7–8, higher placental monocyte chemoattractant protein-1 expression was associated with a 1.6% higher odds of myopia, a 0.008 diopter reduction in spherical equivalent, and a 0.006 mm increase in axial length, although these associations were not statistically significant after correction for multiple comparisons.
What the research says
Challenges is higher
Challenge is ahead, but a single strong supporting study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
In children followed from birth to age 7–8, higher levels of a specific protein in the placenta were linked to slightly higher odds of myopia, a small decrease in eye focusing power, and a small increase in eye length, but these links were not strong enough to rule out chance after accounting for multiple tests.
See the scientific wording
Among 1256 children followed from birth to age 7–8, placental monocyte chemoattractant protein-1 expression was associated with a 1.6% higher odds of myopia, a 0.008 diopter reduction in spherical equivalent, and a 0.006 mm increase in axial length, but these associations did not remain statistically significant after correction for multiple comparisons.
Higher levels of a signaling protein in the placenta trigger a mild, ongoing inflammatory response that changes how the eye grows before birth, leading to a longer eyeball and nearsightedness.
What the research says
1 studyScientists found a tiny link between a placental protein and nearsightedness in kids, but when they checked if it was real or just luck, the link disappeared. So, it probably doesn’t mean anything.
