Distinguishing subclinical from clinical keratoconus by corneal measurements.

Purpose: The study aimed to determine the stability of topographic and tomographic indices measured with Pentacam and to evaluate the biomechanical parameters measured with Corvis ST in the diagnosis of subclinical keratoconus (sKCN) and clinical keratoconus (KCN).

Methods: This is a single-center cohort study with a retrospective review of topographic and tomographic indices and biomechanical parameters on adult patients with subclinical keratoconus (sKCN), clinical keratoconus (KCN), and healthy subjects (control group). The area under the receiver operating curve (AUC) was used to identify the cutoff values for evaluated indices able to distinguish between subjects with sKCN and those with KCN.

Intraoperative Iris Behavior during Phacoemulsification Maneuvers in Rabbits Treated with Selective α1-Blocker, 5α-Reductase Inhibitor, or Anxiolytic Medication.

This prospective, experimental study aims to evaluate the association between administration of α-blocker, 5α-reductase inhibitor, or anxiolytic medications and intraoperative floppy iris syndrome (IFIS) using a rabbit animal model. A total of 31 Metis rabbits were distributed into four groups as follows: 10 rabbits given tamsulosin, 10 rabbits given finasteride, 5 rabbits who received lorazepam, and 6 treatment-naive animals in the control group. Dosing was calculated according to body surface area ratio of man to rabbit, with a dosing duration of 43 days for all groups.

Photochemical Crosslinking of Tarsal Collagen as a Treatment for Eyelid Laxity: Evaluation in Ex Vivo Human Tissue.

Purpose: Experimental investigation in human eyelids to confirm that exposing excised tarsal plates to ultraviolet-A radiation can induce a stiffening effect through the riboflavin-photosensitized crosslinking of tarsal collagen.

Methods: Thirteen tarsal plates excised from nonfrozen human cadavers were irradiated with ultraviolet-A rays (365 nm wavelength) at an irradiance of 75 mW/cm 2 for 3 minutes, equivalent to a radiation fluence of 13.5 J/cm 2 , in the presence of a riboflavin derivative as a photosensitizer.

Retinal Structural and Vascular Changes in Patients with Coronary Artery Disease: A Systematic Review and Meta-Analysis.

Background: Retinal microvascular anomalies have been identified in patients with cardiovascular conditions such as arterial hypertension, diabetes mellitus, and carotid artery disease. We conducted a systematic review and meta-analysis (PROSPERO registration number CRD42024506589) to explore the potential of retinal vasculature as a biomarker for diagnosis and monitoring of patients with coronary artery disease (CAD) through optical coherence tomography (OCT) and optical coherence tomography angiography (OCTA).

Methods: We systematically examined original articles in the Pubmed, Embase, and Web of Science databases from their inception up to November 2023, comparing retinal microvascular features between patients with CAD and control groups.

Long term visual outcomes in cataract surgery with bilateral implantation of the Extended Depth of Focus Intraocular Lens - Mini Well Ready type.

To evaluate the refractive results, visual outcomes and patients' satisfaction of a new extended depth-of-focus (EDOF) intraocular lens (IOL). Oculens Clinic, Cluj-Napoca, Romania. Retrospective, single-center, observational study.

Comparative Results Between "Epi-Off" Accelerated and "Epi-Off" Standard Corneal Collagen Crosslinking-UVA in Progressive Keratoconus - 7 Years of Follow-Up.

Purpose: The purpose of the present study was to assess the long-term efficiency and safety of the "epi-off" accelerated CXL (9 mW/cm for 10 minutes) in comparison to the standard "epi-off" CXL (3 mW/cm for 30 minutes) in terms of topographical and keratometric parameters, refractive data and visual outcomes at 7 years of follow-up, in progressive keratoconus.

Material And Method: A retrospective and comparative study was performed. A total of 183 eyes from 183 patients with documented progressive keratoconus were included in the study.

Intraosseous venous malformation of the zygomatico-orbital complex. Case report and literature review with focus on confusions in vascular lesion terms.

Intraosseous vascular malformations (VascM) of the facial skeleton are rare entities, raising difficulties even today in their treatment. We present a case for zygomatic intraosseous venous malformation of traumatic etiology with growth dynamics presentation and a multidisciplinary treatment approach, with intravascular embolization surgical ablation and primary reconstructruction using a titanium patient-specific implant (PSI), and a review of the literature for intraosseous vascular lesions of the facial skeleton focusing on the diagnostic syntagms used by the involved medical personnel, to shed light on the confusions over these terms.

NONICHEMIC CENTRAL RETINAL VEIN OCCLUSION ASSOCIATED WITH HEREDITARY THROMBOPHYLIA.

Retinal vein occlusion (RVO) is the second most common retinal vein disease with significant visual loss via thrombus or compression of vein wall. Thrombophilia is the predisposition to vascular thrombosis with the existence of genetic defect that leads to blood hypercoagulability. This report describes the case of a 55 year old male patient, with an active life who presented himself at the emergency room with acute visual lose, insidious and progressive visual field constriction, without any known history of neurological or vascular diseases.

A study on the type of lesions achieved by three electrosurgical methods and their way of healing.

The technical progress in the medical sector in the past decades has continuously driven the development of electrosurgical techniques. The controversies surrounding the superiority of a certain technique relative to another - electrocautery, laser and radiofrequency - have determined us to carry out a histopathological design with the aim of comparing the healing sort of the shallow wounds generated by the three types of electrosurgical devices. The experimental study has investigated the healing process inflicted by the electrosurgical devices mentioned beforehand on 12 Wistar albino rats.
