A cost-saving, picture-assisted method for toric intraocular lens alignment versus manual self-leveling marking via RoboMarker.

Purpose: To determine the accuracy of two axis-marking methods for toric intraocular lens (IOL) implantation, one picture-assisted approach based on scleral vessel vectors, and the other based on a self-leveling device for manual marking.

Methods: This retrospective single-center study involved 60 eyes of 51 participants, who underwent phacoemulsification with toric IOL implantation. In all eyes, preoperative markings were made in a seated position both manually via a self-leveling corneal marker (RoboMarker), and digitally on slit-lamp photographs, defining scleral vessels as landmarks, aiding to find the correct intraoperative orientation for an angular graduation instrument.

Matched case-control comparison of surgical success after XEN45 Gel Stent and PRESERFLO MicroShunt implantation in a Caucasian population.

Background: The aim of this study was to compare the outcome of implantation of a XEN45 Gel Stent with the outcome of implantation of a Preserflo MicroShunt in a matched-pair analysis in eyes being naïve to filtering surgery.

Methods: In this comparative, retrospective study, 50 eyes that had undergone XEN45 Gel Stent implantation were compared with 50 eyes after Preserflo implantation. Follow-up was at least 6 months, and surgical success was measured by criteria A (IOP < 21 mmHg, IOP reduction >20%, no repeat surgery); criteria B (IOP < 18 mmHg, IOP reduction >20%, no repeat surgery); and criteria C (IOP ≤15 mmHg, IOP reduction ≥40%, no repeat surgery).

Susceptibility of optic nerve head in children with posture-related elevation of intraocular pressure.

Background/aims: This work aimed to investigate changes in optic nerve head (ONH) morphometry based on Bruch membrane opening in children with extensive nocturnal intraocular pressure (IOP) elevations.

Methods: The course of Bruch membrane opening-based optic nerve head (ONH) morphometry was analysed in thirty-two patients younger than 18 years with evaluable SD-OCT examinations of the ONH and nocturnal posture-dependent IOP elevation above 25 mmHg. Longitudinal changes in neuroretinal rim tissue, as measured by Bruch Membrane opening minimum rim width (BMO-MRW) and peripapillary retinal nerve fiber layer (RNFL) thickness, were assessed.

Value of addition of coronary artery calcium to risk scores in the prediction of major cardiovascular events in patients with type 2 diabetes.

Background: The increased risk for cardiovascular events in diabetics is heterogeneous and contemporary clinical risk score calculators have limited predictive value. We therefore examined the additional value of coronary artery calcium score (CACS) in outcome prediction in type 2 diabetics without clinical coronary artery disease (CAD).

Methods: The study examined a population-based cohort of type 2 diabetics (n = 735) aged 55-74 years, recruited between 2006 and 2008.

Combined ab-interno trabeculectomy and cataract surgery induces comparable intraocular pressure reduction in supine and sitting positions.

Aim: To analyze the therapeutic effect of combined ab-interno trabeculectomy and cataract surgery on intraocular pressure (IOP) levels in supine and sitting postures during a 24-hour IOP profile.

Methods: Twenty-six eyes of twenty-six patients receiving ab-interno trabeculectomy using electroablation of the trabecular meshwork combined with cataract surgery or stand-alone were included in this retrospective analysis. IOP change during 24-hour IOP profiles within two years postoperatively were analyzed for eyes receiving surgery ("study eyes") and compared to fellow eyes, which had not received surgery.

Conjunctival repair after glaucoma drainage device exposure using collagen-glycosaminoglycane matrices.

Background: To report the results of the repair of conjunctival erosions resulting from glaucoma drainage device surgery using collagen-glycosaminoglycane matrices (CGM).

Methods: Case series of 8 patients who underwent revision surgery due to conjunctival defects with exposed tubes through necrosis of the overlying scleral flap and conjunctiva after Baerveldt drainage device surgery. The defects were repaired by lateral displacement of the tube towards the sclera, with a slice of a CGM as a patch, covered by adjacent conjunctiva.

The effect of additional trabecular aspiration to phacoemulsification and trabectome as a triple procedure in pseudoexfoliation glaucoma: a case-matched study.

Background: Trabectome surgery combined with phacoemulsification is effective in lowering (intraocular pressure) IOP in pseudoexfoliation glaucoma. Trabectome surgery usually aims to remove two to four clock hours of the trabecular meshwork. When adding trabecular aspiration, the remaining meshwork can be treated as well, and therefore 360 degrees of the meshwork can be reached.
