This study found that post-trabeculotomy, anterior chamber clot formation, unlike simple hyphema, leads to higher post-operative IOP spikes, prolonged bleeding, and increased reoperation risk, impacting patient outcomes.

This study found pars plana Baerveldt implant insertion caused less corneal endothelial cell loss and bullous keratopathy than pars limbal, especially with low preoperative cell density, guiding surgical choice.

This study found foveal detachments near the Müller cell cone after glaucoma surgery are significant risk factors for persistent visual acuity loss, highlighting a critical complication.

The study found XFS patients with the CYP39A1 G204E mutation have significantly increased blindness risk, more severe glaucoma, and higher rates of XFG, indicating a critical genetic factor for prognosis.

This study found that very low pressure one week post-glaucoma surgery increased mid-term visual loss, while an epiretinal membrane was a significant long-term risk factor for visual decline.

Ripasudil significantly increased peripapillary vessel density in glaucoma/OH patients, unlike brimonidine, suggesting a novel mechanism for improving ocular blood flow clinically.

OCTA vessel density and prelaminar flow index were studied; vessel density was better at differentiating glaucoma and OH from normal eyes than PLFI, but inferior to structural OCT.

This study found that adding a fenestration to deep sclerectomy for glaucoma lowered IOP but suppressed bleb formation, resulting in similar overall IOP reduction as deep sclerectomy alone.

This study found high myopia impairs cpRNFL's, but not GCC's, ability to detect glaucoma. Therefore, GCC parameters are crucial for glaucoma diagnosis in highly myopic patients.

Chihara Etsuo, Hayashi Ken

This study found the "lake" volume after D-lectomy glaucoma surgery poorly correlates with IOP reduction, suggesting transscleral outflow is a minor mechanism for pressure lowering.

Shoji Takuhei, Sato Hiroki, Ishida Masahiro, Takeuchi Masaru, Chihara Etsuo

This study found SD-OCT's ganglion cell complex (GCC) parameters, particularly Global Loss Volume, are best for detecting glaucoma in highly myopic eyes, offering improved clinical diagnosis.

Oku Yoshiko, Oku Hidehiro, Park Masami, Hayashi Ken, Takahashi Hirokazu, Shouji Takuhei et al.

This study found long axial length is a significant risk factor for both normal tension and primary open-angle glaucoma, suggesting patients with longer eyes need careful glaucoma screening.

Modified deep sclerectomy (D-lectomy MMC) achieved comparable IOP reduction to trabeculectomy for glaucoma, but with fewer filtering blebs. This suggests a potentially effective alternative with different post-operative characteristics.

Park Masami, Hayashi Ken, Takahashi Hirokazu, Shoji Takuhei, Chihara Etsuo

This study found high preoperative IOP, more medications, and postoperative IOP spikes increase the risk of uncontrolled pressure after phacoviscocanalostomy, while older age decreases risk.

This review found Goldmann tonometry, the IOP gold standard, lacks precision needed for glaucoma management, as corneal properties and other factors significantly affect its accuracy, necessitating better measurement tools.

Takahashi Hirokazu, Chihara Etsuo

This study found mild diabetic retinopathy causes RNFL measurement differences between GDx-VCC and StratusOCT in healthy eyes, but both devices remain effective for glaucoma detection even with diabetes.

Phacoviscocanalostomy for normal-tension glaucoma and cataract significantly lowered IOP and better preserved visual fields compared to cataract surgery alone, offering a safe, effective combined treatment.

Park Masami, Hayashi Ken, Takahashi Hirokazu, Tanito Masaki, Chihara Etsuo

Phaco-viscocanalostomy provided better IOP control and fewer complications than phaco-trabeculotomy in open-angle glaucoma, suggesting it's a safer, more effective surgical option.

Diabetes thins the retinal nerve fiber layer, worsening with retinopathy severity, which can lead to false-positive glaucoma diagnoses using scanning laser polarimetry.

Park Masami, Tanito Masaki, Takahashi Hirokazu, Chihara Etsuo

Studying phaco-viscocanalostomy, JCT peeling didn't improve long-term IOP but reduced early IOP spikes and complications. This adjunctive step may benefit glaucoma patients.

Park Masami, Tanito Masaki, Nishikawa Maki, Chihara Etsuo

UBM showed the intrascleral lake size decreased over 12 months post-viscocanalostomy/cataract surgery, correlating with IOP reduction. This suggests lake maintenance is crucial for long-term IOP control.

Takahashi Hirokazu, Tanito Masaki, Yokoyama Mitsunobu, Park Masami, Chihara Etsuo

Endoscopy during viscocanalostomy showed viscoelastic material filling and disrupting Schlemm's canal, suggesting inner wall disruption contributes to IOP reduction, improving glaucoma treatment understanding.

Tanito Masaki, Itai Noriko, Ohira Akihiro, Chihara Etsuo

This study found that perifoveal retinal thickness is significantly reduced in preperimetric and established glaucoma, correlating with visual field loss, offering a potential early diagnostic tool.

Tanito Masaki, Itai Noriko, Dong Jin, Ohira Akihiro, Chihara Etsuo

This study found that better IOP control (below 21 mmHg) correlates with less optic disc damage in high-tension glaucoma suspects, suggesting a target pressure between 18-21 mmHg is beneficial.
