A 4-Year Retrospective Study: Clinical Outcomes of XEN45 in Patients with Glaucoma.

Introduction: The main purpose of the current study was to evaluate the long-term effectiveness and safety of XEN45 implant, either alone or in combination with cataract surgery, in patients with glaucoma.

Methods: Retrospective and single center study conducted on consecutive patients who underwent a XEN45 implant, either alone or in combination with cataract surgery, between November 2016 and October 2021. The primary endpoint was the mean intraocular pressure (IOP) lowering from preoperative values.

Study of perfusion changes in the optic disc of patients with fibromyalgia syndrome using new colorimetric analysis software.

Purpose: We measured the amount of hemoglobin at the optic nerve head of fibromyalgia (FM) patients using new colorimetric analysis software. We also investigated whether perfusion defects of the optic nerve head in patients with FM lead to tissue atrophy and corresponding retinal nerve fiber layer (RNFL) thinning measured by optical coherence tomography (OCT).

Methods: We recruited for this cross-sectional study 118 FM patients and 76 sex- and age-matched healthy controls.

Analysis of optic disk color changes in Alzheimer's disease: a potential new biomarker.

Purpose: In the present study, we evaluated changes in the retinal nerve fiber layer (RNFL) and optic disk color (i.e., the level of paleness as an indirect sign of axonal loss) in patients with Alzheimer's disease (AD) compared with healthy controls.

Measuring hemoglobin levels in the optic disc of Parkinson's disease patients using new colorimetric analysis software.

Objective. To evaluate a new method of measuring hemoglobin (Hb) levels and quantifying the color changes in the optic nerve head of Parkinson's disease (PD) patients. We also compared differences in retinal nerve fiber layer (RNFL) thicknesses obtained using spectral domain optical coherence tomography (OCT) device between PD group and healthy group.

Detecting Optic Atrophy in Multiple Sclerosis Patients Using New Colorimetric Analysis Software: From Idea to Application.

Neuro-ophthalmologists typically observe a temporal pallor of the optic disc in patients with multiple sclerosis. Here, we describe the emergence of an idea to quantify these optic disc color changes in multiple sclerosis patients. We recruited 12 multiple sclerosis patients with previous optic neuritis attack and obtained photographs of their optic discs.
