Narrative review of mechanistic models without systematic methodology or primary human data.

What was done
This narrative review summarizes the current understanding of the ocular glymphatic system, focusing on bidirectional polarized fluid transport pathways across the optic nerve and addressing diverging mechanistic definitions generated by differing methodologies.
What was found
The abstract reports no numerical data. It describes that cerebrospinal fluid moves from the brain along periarterial spaces toward the eye, while retinal fluid travels along perivenous spaces following axonal transport across the glial lamina, noting that methodological variations have led to conflicting mechanistic models.
Why it matters
Elucidating ocular fluid dynamics and waste clearance pathways may identify novel therapeutic targets for common blinding diseases such as glaucoma, diabetic retinopathy, and age-related macular degeneration.
Limits
As a narrative review, this article presents no original human or experimental data and does not employ systematic review methods. The abstract explicitly highlights existing confusion and conflicting mechanistic models in the field.
