Chapter 2: Intraocular Pressure and Tonometry

Teng Ruiwen, Luo Jia, Zhao Peiquan et al.

A model predicts altitude-related IOP spikes post-vitrectomy with gas, finding varied safe travel intervals by gas type, offering personalized risk assessment for patients.

Daas Arij, Patel Bhavin, Ranjit Ananth et al.

MP-TSCPC reduces IOP in glaucoma/OHT primarily by decreasing aqueous humor production, not outflow. This clarifies its mechanism, supporting its safe, effective use.

Rocks Madeline C, Dossantos Jason, Tran Hoang-Viet et al.

This study found OMNI canaloplasty with or without a Hydrus microstent during cataract surgery yielded comparable IOP, medication, and success rates at one year, suggesting the microstent may not add significant benefit.

Cai, Yuting, Zhang, Chenguang, Dang, Pengrui et al.

This smart contact lens monitors eye pressure and automatically releases glaucoma medication when pressure is high, offering a personalized, real-time treatment solution.

Steger Jennifer S, Capó-Aponte José E, Papp Alexandra et al.

Microdrops via Nanodropper showed better IOP lowering, reduced bottle exhaustion, and fewer side effects than conventional drops, potentially improving glaucoma treatment adherence and control.

Fabian Ekkehard, Janeková Andrea, de Arriba Palomero Pablo et al.

This study found Z-HYALCOAT non-inferior to HEALON EndoCoat for cataract surgery, showing similar IOP spikes, endothelial cell loss, and overall safety. This offers clinicians another comparable OVD option.

Zhou Lin, Zhao Chenzhu, Li Dongfeng et al.

This study established normative wide-field retinal and choroidal thickness in Chinese children, finding distinct patterns influenced by age, myopia, and other ocular parameters, aiding early disease detection and monitoring.

Suzuki Hisaharu, Kurose Mai, Horie Takashi et al.

A study on porcine eyes found the UNITY system maintained anterior chamber stability significantly better than Centurion during simulated phacoemulsification occlusion breaks, potentially improving surgical safety and surgeon confidence.

Miller Kevin M, Aboughaida Ali, Dyk David et al.

This study compared phacoemulsification systems, finding UNITY® had 44% lower occlusion break surge than CENTURION®. This reduces intraocular pressure fluctuations, potentially improving safety and confidence in complex cataract surgery.

Yepez Juan B, Murati Felipe A, Kozak Igor et al.

A novel plungerless injector for aqueous humor sampling proved feasible and safe, offering more consistent aspiration, shorter procedure times, and less discomfort than conventional methods.

Vasavada Shail, Dwivedi Shyamal, Vasavada Vaishali et al.

This study found that low intraoperative IOP (20mmHg) during cataract surgery in diabetic retinopathy patients improved macular and optic nerve perfusion, suggesting a beneficial clinical effect.

Araújo-Azevedo Beatriz, Ferreira-da-Silva Renato, Barbosa-Breda João

This study found that lowering intraocular pressure to single digits in progressive normal-tension glaucoma significantly slows visual field loss, but carries a risk of hypotony-related complications.

Sng Jie James, Park Ki Ho, Kim Young Kook et al.

AS-OCT revealed persistent structural differences in primary angle closure disease eyes even after LPI, suggesting its utility for assessing risk and severity post-treatment.

Tempelhof Ortal Fogel, Reich Yael, Rachmiel Rony et al.

Face masks inconsistently affect Goldmann tonometry, causing clinically significant IOP changes (≥3 mmHg) in one-third of patients, warranting re-measurement without a mask for accurate glaucoma management.

Narainswami Neeran, Chavez Matheus Pedrotti, Sperotto Pedro Henrique Ferrazza et al.

This study found slow-coagulation cyclophotocoagulation lowers eye pressure more than micropulse, similarly to continuous wave, with comparable safety. It's a viable non-incisional glaucoma treatment option.

Uzel Mehmet Murat, Koçer Ali Mert, Aksoy Bekir Eren et al.

Trabecular meshwork peeling during hemi-GATT significantly reduces early postoperative IOP spikes, improving early IOP control without compromising surgical success, offering a safer procedure.

Wu Na, Aihemaiti Xianmuseye, Sun Xinghuai et al.

In untreated glaucoma, higher corneal deformability (less stiffness) was associated with lower 24-hour intraocular pressure variation. This suggests corneal properties may influence IOP measurement and glaucoma management.

Lanza Michele, Boccia Rosa, Scutifero Marianna et al.

Zhang Yue, Padhee Swati, Yuhas Phillip T et al.

A novel AI model accurately predicted ocular stiffness from ORA waveforms, improving keratoconus detection. This expands ORA's utility for biomechanical assessment and diagnosis in clinical settings.
