Preserflo TM MicroShunt implantation combined with Ologen TM in primary and secondary glaucoma patients in a clinical setting.

Purpose: This study aims to assess the effectiveness and safety of combining the Preserflo™ MicroShunt implant (MicroShunt) with a simultaneous Ologen™ implant in patients with glaucoma.

Methods: We conducted a retrospective study on consecutive patients with medically uncontrolled glaucoma who underwent MicroShunt + Ologen implantation as a standalone procedure or in combination with phacoemulsification (combined procedure). Success was defined as achieving an intraocular pressure (IOP) of 6-15 mmHg at 18 months post surgery, with a preoperative IOP reduction of at least 20%, and without (complete success) or with (qualified success) the need for antiglaucoma medications.

The influence of altitude on the differences between Goldmann tonometry and Pascal dynamic contour tonometry: An ecological meta-analysis.

Purpose: A meta-analysis found that including atmospheric pressure as altitude in generalized linear models reveals higher differences between Goldmann tonometry and Pascal dynamic contour tonometry at higher altitudes, with the difference increasing in thinner corneas. To examine the difference in intraocular pressure (IOP) measurements by using Goldman applanation tonometry (GAT) and dynamic contour tonometer (DCT) tonometry in published literature and determine the influence of central corneal thickness (CCT), age, and altitude on that difference.

Methods: Articles that compare GAT and DCT were selected for an extensive literature review, and the location and altitude of the research centers were found online.

Results of a modified ab-external trabeculectomy surgical technique in patients with open angle glaucoma.

Objective: Assess the safety and efficacy of a Modified Ab-externo Trabeculectomy surgical technique in controlling intraocular pressure (IOP) in open-angle glaucoma patients.

Methods And Analysis: Patients diagnosed with primary or secondary open-angle glaucoma underwent this modified technique as the first filtering surgical treatment were included. The preoperative and final follow-up assessed IOP, hypotensive medications, the need for additional treatments, and early and late complications.

New Gonioscopy Technique for Finding Schwalbe's Line: The Ortiz Maneuver.

Unlabelled: A new technique for performing gonioscopy that facilitates finding Schwalbe´s line, and lowers the amount of time and light that enters through the pupil is presented. The technique is an alternative to the classic corneal wedge technique and is feasible in the horizontal quadrants without further adjustments to the slit lamp, in contrast to the tilting usually needed for these quadrants. Clinical photos and online videos are presented.

Duration of the hypotensive effect of prostaglandin analogues measured with the water drinking test in glaucoma patients.

Objective: To measure the magnitude and duration of the hypotensive effect of two prostaglandin analogues in glaucoma patients using the water drinking test (WDT).

Methods: Patients received latanoprost or travoprost every 24 h and then every 48 h. Untreated WDT were performed at 7 am and with treatment 12, 36 and 44 h after the last dose; intraocular pressure (IOP) peak, fluctuation and the difference between peak and isolated IOP measurements at consultation times were calculated.
