This study found optic nerve kinking is significantly more common in Normal Tension Glaucoma patients (86%) than controls (18%), suggesting a potential role in NTG development.

In asymmetric glaucoma, the more damaged eye had significantly lower corneal hysteresis and pulsatile ocular blood volume, suggesting these metrics may indicate disease progression independent of IOP.

ICRS in keratoconus significantly stiffened the cornea, improving biomechanics and providing structural support. This suggests a beneficial long-term effect on corneal integrity.

This study found normal corneal stress is thickness-driven, but in keratoconus, maximum stress shifts from the thinnest point as the disease progresses, highlighting biomechanical decompensation.

NCTs don't form droplets in standard use. With eye drops, droplets can form near the lower eyelid, suggesting holding eyelids open carefully if assistance is needed to avoid forward droplet spread.

Prostaglandin use in glaucoma patients was linked to scleral biomechanical changes, affecting IOP measurements. This suggests standard tonometry may be inaccurate and the IOP/ACV ratio could predict treatment success.

Scleral buckling for retinal detachment alters corneal biomechanics, reducing corneal hysteresis. This suggests SB eyes have less compliant corneas, potentially affecting IOP measurement accuracy and glaucoma management.

Researchers developed and validated a new algorithm (bIOPs) for soft corneas, showing it reliably estimates IOP in keratoconus, improving accuracy over standard methods and reducing corneal biomechanics dependence.

This study found that a new biomechanically corrected IOP measurement (bIOP) remained stable after LASIK/SMILE, unlike traditional methods. This suggests bIOP may provide more accurate glaucoma screening post-refractive surgery.

This study found corneal refractive surgeries (PRK/LASIK) don't alter biomechanically corrected IOP. PRK caused less corneal biomechanical change than LASIK, suggesting it's biomechanically safer.

Combined PRK and CXL for myopia reduced corneal biomechanical changes compared to PRK alone, suggesting CXL stabilizes the cornea. Biomechanically corrected IOP remained stable.

Corneal biomechanics impact refractive surgery outcomes and IOP measurement accuracy. Altered corneas, especially after thinning, invalidate standard IOP readings, requiring alternative technologies for reliable assessment.

This study found Goldmann applanation tonometry (GAT) underestimated IOP after corneal transplant. Corneal biomechanics, not thickness, significantly influenced IOP readings, suggesting GAT may be less accurate in these eyes.

This study found a contact lens sensor accurately measures IOP and ocular pulse amplitude, comparable to standard tonometers, offering a viable method for continuous monitoring.

LASIK and LASEK both reduce IOP and alter corneal biomechanics. LASIK causes greater biomechanical changes, especially with deeper ablation, impacting accurate IOP measurement and glaucoma risk assessment.

LASIK alters corneal biomechanics and lowers most IOP readings, but the Pascal tonometer (PDCT) remains stable, suggesting it's more reliable for post-LASIK glaucoma management.

Liu Jun, Roberts Cynthia J

This study quantified how corneal properties, especially biomechanics, significantly alter applanation tonometry readings from true intraocular pressure. This highlights the need to account for individual corneal variations for accurate glaucoma diagnosis.
