The Claim
Glaucoma patients with retinal vein occlusion have a significantly lower choroidal vascularity index (64.62 ± 7.38%) than glaucoma patients without retinal vein occlusion (67.49 ± 5.90%), indicating reduced choroidal vascular density in the presence of retinal vein occlusion.
What the research says
Supports is higher
Support is ahead, but a single strong opposing 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.
Among people with glaucoma, those who also have retinal vein occlusion show a measurable reduction in choroidal vascular density compared to those without retinal vein occlusion.
See the scientific wording
Glaucoma patients with retinal vein occlusion exhibit a significantly lower choroidal vascularity index (64.62 ± 7.38%) compared to those without retinal vein occlusion (67.49 ± 5.90%), indicating reduced choroidal vascular density in the presence of RVO.
When the nervous system fails to properly regulate blood vessel tone, blood flow to the layer behind the retina drops, causing the vessels there to shrink and slow down. This sluggish flow makes blood more likely to clot in the veins of the retina, which further reduces blood supply and leads to fewer visible blood vessels in the choroid.
What the research says
1 studyGlaucoma patients who had a blocked vein in their eye were found to have slightly less blood vessel volume in the layer behind the retina than glaucoma patients without the blockage — the study measured this directly and found a real difference.
