SILICONE FINE-NEEDLE ASPIRATION RETINAL BIOPSY: A Novel Surgical Technique for Vitreoretinal Lymphoma.

Purpose: To describe a 41-gauge silicone fine-needle aspiration biopsy (S-FNAB) technique and assess its value in diagnosing primary vitreoretinal lymphoma (PVRL).

Methods: Retrospective review of seven consecutive patients who underwent vitreous biopsy (VB) and 41-gauge S-FNAB of retinal/subretinal lesions in a single tertiary center between January 2012 and March 2023.

Results: Of seven patients, S-FNAB confirmed the diagnosis of PVRL in six patients.

Morphological and functional parameters in X-linked retinoschisis patients-A multicentre retrospective cohort study.

Introduction: X-linked retinoschisis (XLRS) is a potential target for gene supplementation approaches. To establish potential structural and functional endpoints for clinical trials, a comprehensive understanding of the inter-eye symmetry, relationship between structural and functional parameters, and disease progression is vital.

Methods: In this retrospective multicentre study, 118 eyes of 59 XLRS patients with mutations were assessed.

Various clinical presentations of uveitis associated with durvalumab treatment.

Background: Immune checkpoint inhibitors (ICI) are becoming increasingly common in treating several cancer types. Durvalumab is a human IgG1 monoclonal antibody that blocks PD-L1 binding to PD-1 and CD80 and has recently been approved for the treatment of extensive-stage small-cell lung cancer (ES-SCLC) and locally advanced unresectable (NSCLC). The present review aimed to analyse immune-mediated uveitis, secondary to durvalumab treatment, through a review of the literature and a presentation of two clinical cases.

Disease Progression in and Retinopathy; Characteristics of Slovenian Cohort and Proposed OCT Staging Based on Pooled Data from 126 Patients from 7 Studies.

Achromatopsia has been proposed to be a morphologically predominately stable retinopathy with rare reports of progression of structural changes in the macula. A five-grade system of optical coherence tomography (OCT) features has been used for the classification of structural macular changes. However, their association with age remains questionable.

Repurposing beta-3 adrenergic receptor agonists for Alzheimer's disease: beneficial effects in a mouse model.

Background: Old age, the most important risk factor for Alzheimer's disease (AD), is associated with thermoregulatory deficits. Brown adipose tissue (BAT) is the main thermogenic driver in mammals and its stimulation, through β3 adrenergic receptor (β3AR) agonists or cold acclimation, counteracts metabolic deficits in rodents and humans. Studies in animal models show that AD neuropathology leads to thermoregulatory deficits, and cold-induced tau hyperphosphorylation is prevented by BAT stimulation through cold acclimation.

Automated Visual Acuity Evaluation Based on Preferential Looking Technique and Controlled with Remote Eye Tracking.

Objective: To establish an automated visual acuity test (AVAT) for infants, based on preferential looking technique and controlled with remote eye tracking. To validate the AVAT in a group of healthy children. To compare AVAT visual acuity (VA) values with corresponding VA values acquired with standard tests (ST).
