PURPOSE: To study the composition of corneal astigmatism in older adults, evaluating the difference made by the inclusion of posterior corneal astigmatism in a ray tracing calculation of total corneal astigmatism. SETTING: Ophthalmology clinic. METHODS: One hundred consecutive patients aged between 60 and 80 years were included in a prospective descriptive study. Their right eye was analysed by an integrated Placido disk and rotating Scheimpflug camera topographer (CSOTM Sirius). Several parameters were measured: anterior corneal astigmatism (ACA) and posterior corneal astigmatism (PCA), total astigmatism based on anterior topographic data (simK) and total corneal astigmatism (TCA) by merging anterior and posterior astigmatism using ray tracing. RESULTS: Mean ACA was 1.51 diopters (D) and PCA was 0.38D. ACA was aligned 47% with-the-rule and PCA 87% against-the-rule. Cases with against-the-rule ACA showed low magnitude correlation between anterior and posterior surfaces. TCA had a mean deviation of 0.30D @ 3 over SimK in a vector calculation. Eighteen percent (18%) of cases differed by 0.50 D or more between SimK and TCA magnitude, and 53% had 10 or more degrees of axis discrepancy, the difference being higher at lower magnitudes of astigmatism. CONCLUSIONS: Anterior WTR astigmatism tends to be compensated by posterior ATR astigmatism in older patients. Nevertheless, the high number of cases largely justifies the use of tomographic technology that takes into account the posterior corneal surface for managing individual total corneal astigmatism.

Objectives: The aim of this study was to compare sonoelastographic findings in the retina– choroid–sclera (RCS) complex and vitreous in glaucomatous and healthy eyes.Methods: For this cross-sectional comparative study, 20 patients with primary open-angle glaucoma (POAG) and 20 healthy volunteers were recruited. Ultrasound elastography measurements were taken with a sonographic scanner of the RCS complex, anterior vitreous (AV), posterior vitreous (PV), retrobulbar fat tissue (RFT), optic disc, and optic nerve in each eye.Results: The elasticity index of the RCS complex, RFT, optic disc, optic nerve, AV, and PV were similar in both groups (p > 0.05), though the AV/PV strain ratio in the group of patients with glaucoma was significantly higher (p = 0.04).Conclusion: Glaucoma increases the AV/PV strain ratio. In providing reproducible and consistent values, the real-time elastography technique may be helpful in elucidating the mechanisms of glaucoma in some aspects.

A transition period regarding in vitro medical device (IVD) regulation in the European Union (EU) is upon us. The former IVDD regulations are phasing out and IVDR 2017/746 has already taken its place as the acting regulation for IVD manufacturers but also lab developed tests (LDTs) and health institutions. In our upcoming webcast we will talk about the roles and significance of IVDR and ISO 13485 certification for clinical labs and for Golden Helix as a medical device manufacturer. Join us as we will introduce VarSeq 2.6.1 complete with Dx Mode, which offers the use of VarSeq as CE marked medical device. Even more we will also present strategies to facilitate the transition of Golden Helix customers to operate in accordance with IVDR.

Overview: Join Dr. Faiza in this in-depth lecture on cardiac impulse and the rhythmical excitation of the heart. This presentation covers the intricate pathways and mechanisms that ensure the efficient conduction of electrical impulses through the heart, leading to coordinated myocardial contractions. Attendees will gain a comprehensive understanding of the normal sequence of cardiac depolarization, the specialized conductive pathways, and the ionic basis of pacemaker potentials. Learning Objectives: Trace the normal sequence of cardiac depolarization via specialized conductive pathways and cardiac myocytes. Illustrate the velocity of conduction of cardiac impulses through these pathways. Draw and label a typical pacemaker action potential. Describe the ionic basis of various phases of the pacemaker potential. Key Topics: Generation of Impulse: Mechanisms of rhythmical excitation in the heart. Conduction of Impulse: How impulses are transmitted and why atrial syncytium contracts ahead of ventricular syncytium. Specialized Excitatory & Conductive System: Detailed examination of the SA node, AV node, bundle branches, and Purkinje fibers. SA Nodal Action Potential: Phases of pacemaker potential, ionic movements, and self-excitation mechanisms. Transmission Pathways: Role of anterior and posterior fascicles, internodal, and interatrial pathways. Clinical Significance: Implications of delayed conduction and conditions like Stokes-Adams syndrome and ectopic pacemakers. Target Audience: This lecture is tailored for medical students, physiology scholars, healthcare professionals, and anyone interested in cardiac physiology and the mechanisms of cardiac impulse conduction. It is particularly beneficial for those preparing for exams or seeking to enhance their clinical knowledge in Applied physiology of cardiovascular system and internal medicine.
