This study found ciliochoroidal detachment is common after Preserflo MicroShunt surgery. Short axial length and postoperative hypotony are key risk factors, informing patient selection and monitoring.

Preserflo MicroShunt implantation was linked to corneal endothelial cell reduction, especially with a narrower tube-cornea angle and higher preoperative eye pressure, highlighting risk factors for corneal health.

Outer nasal macular perfusion density (MPD) correlates strongly with central visual field loss across all POAG stages. It's a valuable biomarker, particularly in advanced disease, complementing structural OCT when measurements are at their floor.

This study found epiretinal membranes are associated with worse glaucoma severity (thinner RNFL, larger cupping, worse visual fields) in POAG, suggesting ERMs may be a risk factor for progression.

This pilot study found simultaneous intravitreal TA/tPA for CRVO-related macular edema improved vision and reduced swelling in most patients, suggesting a potential treatment option needing further validation.

This study compared RON and tPA cannulation for CRVO, finding no significant difference in visual or edema improvement, but high neovascular glaucoma rates, questioning their overall effectiveness.

Intravitreal bevacizumab effectively treated iris neovascularization and early neovascular glaucoma, but failed to control IOP in advanced cases, which often required surgery.

Intravitreal bevacizumab effectively regressed iris neovascularization in proliferative diabetic retinopathy patients, offering a safe, short-term treatment option for this challenging condition.

Radial optic neurotomy for hemi-CRVO significantly improved visual acuity and prevented neovascularization in a small study, suggesting it may be an effective treatment for this condition.

Chronically implanted microelectrodes in rabbit optic nerves were safe and stable, eliciting electrical potentials for months. This supports their potential for future optic nerve-based prostheses in glaucoma patients.

Researchers successfully stimulated rabbit optic nerves via optic disc electrodes, eliciting cortical potentials with minimal damage. This demonstrates a potential method for vision restoration in optic nerve diseases.
