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.

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.

Diagnostic ability of a new method for measuring haemoglobin levels in the optic nerve head in multiple sclerosis patients.

Aims: To evaluate a new method for measuring haemoglobin (Hb) levels and quantifying the colour changes in the optic nerve head of multiple sclerosis (MS) patients to detect axonal loss and consequently optic disc atrophy.

Material And Methods: 40 MS patients and 40 age and sex-matched healthy subjects were included in this prospective cross-sectional study and underwent a full ophthalmological examination, including three photographs of the optic disc. The Laguna ONhE ('optic nerve hemoglobin'; Insoft SL, Tenerife, Spain) software was used to obtain the Hb analysis in each of the 24 sectors and average Hb of optic disc photographs acquired.

Measuring hemoglobin levels in the optic nerve head: comparisons with other structural and functional parameters of glaucoma.

Purpose: We evaluated and compared the ability of a new method for measuring hemoglobin (Hb) levels at the optic nerve head (ONH) to that of visual field evaluation, scanning laser ophthalmoscopy (HRT), scanning laser polarimetry (GDx), and optical coherence tomography (OCT) for diagnosing glaucoma.

Methods: Healthy eyes (n = 102) and glaucomatous eyes (n = 101) underwent reliable Oculus Spark perimetry, and imaging with the HRT, GDx, and Cirrus OCT. In addition, ONH color images were acquired with a non-mydriatic fundus camera.

Comparison of the efficacy and safety of contact versus peribulbar anaesthesia in combined eye surgery.

Purpose: To compare the combined levels of comfort, the presence of complications and the results of phacotrabeculectomy surgery obtained with 2 different forms of anaesthesia: topical contact anaesthesia and peribulbar injected anaesthesia.

Procedures: In total, 120 consecutive patients undergoing phacotrabeculectomy were randomly assigned to each anaesthesia group. The patients were asked to rate their pain level on a 5-point scale at 3 time points during the procedure.

Contact-topical plus intracameral lidocaine versus peribulbar anesthesia in combined surgery: a randomized clinical trial.

Purpose: To compare the efficiency and safety of contact-topical anesthesia versus peribulbar injection anesthesia for phacotrabeculectomy.

Materials And Methods: A total of 80 patients undergoing combined cataract and glaucoma surgery were randomly allocated to receive either contact or peribulbar anesthesia. No systemic sedatives were used in either group.

Contact versus peribulbar anaesthesia in trabeculectomy: a prospective randomized clinical study.

Purpose: To compare the pre-, intra- and postoperative pain scores and complication rates in trabeculectomy under contact-topical anaesthesia versus peribulbar injection anaesthesia.

Methods: A total of 100 patients selected to undergo primary trabeculectomy were randomly allocated to receive either contact or peribulbar anaesthesia. Patients were asked to rate their pain levels on a 5-point scale for four periods: during the administration of the anaesthetic agent, during surgery, immediately after surgery and 24 hours postoperatively.
