This review examines the history, measurement techniques (tonographic and fluorophotometric methods), and clinical implications of aqueous humor outflow facility as a key parameter in determining intraocular pressure (IOP) and understanding glaucoma pathophysiology and treatment.
Outflow facility is identified as one of 4 core parameters governing IOP, with reduced facility in drainage tissues being the primary driver of pathologic IOP elevation; the review highlights tonography as the main noninvasive clinical tool and calls for standardization of both measurement methods.
Full text was not available — findings are based on abstract only, limiting detail on clinical data summarized. The review does not appear to include original data or a formal systematic methodology, reducing its evidentiary weight.
Clinicians managing glaucoma should be aware that outflow facility measurement (via tonography or fluorophotometry) can provide insight into drainage pathway dysfunction and may help personalize IOP-lowering therapy. Standardization of these methods is still needed before routine clinical adoption.
