Surgical interventions for simple phakic fovea-splitting rhegmatogenous retinal detachment: a comparative study of scleral buckling and pars plana vitrectomy.

National Clinical Research Center for Ocular Diseases, Eye Hospital, Wenzhou Medical University, Wenzhou, China.
Aims: To compare the efficiency of scleral buckling (SB) and pars plana vitrectomy (PPV) with or without SB in patients with primary simple phakic fovea-splitting rhegmatogenous retinal detachment (RRD).
Methods: A retrospective case-control study included 101 patients aged <55 years diagnosed with phakic fovea-splitting RRD. The primary outcome was functional success, defined as achieving a postoperative logarithm of the minimum angle of resolution best-corrected visual acuity of 0.
3',4'-Dihydroxy Flavonol (DiOHF) Exerting a Positive Effect on Neurogenesis and Retinal Damage in Experimental Brain Ischemia-Reperfusion of Rats.
Curr Pharm Des
January 2025
Department of Physiology, Medical School, Selcuk University, Konya, Turkey.
Introduction: Brain ischemia-reperfusion can cause serious and irreversible health problems. Recent studies have suggested that certain flavonoids may help stabilize the correctly folded structure of the visual photoreceptor protein rhodopsin and offset the deleterious effect of retinitis pigmentosa mutations.
Objective: The current study aimed to determine the effect of 3',4'-Dihydroxyflavonol (DiOHF) supplementation for 1 week on lipid peroxidation in the retina tissue following focal brain ischemia-reperfusion in rats.
MicroRNAs' Significance in Retinoblastoma Diagnosis and Treatment: The Little Heroes.

Immunology Research Center, Tabriz University of Medical Sciences, Tabriz, Iran.
One in 16, 000 live births is affected by the retinal tumor RB (retinoblastoma), which is frequently found in a child's early years. Both of the RB1 alleles that have been locally mutated in the affected retina are present in 60 percent of cases. Retinoblastoma (RB) can be detected using a variety of techniques, including imaging of the brain and orbits, eye examinations under anesthesia (EUAs), and the discovery of cell-free tumor DNA in samples of aqueous humor or plasma.

Current teleoperated robotic systems for retinal surgery cannot effectively control subtle tool-to-tissue interaction forces. This limitation may lead to patient injury caused by the surgeon's mistakes. To improve the safety of retinal surgery, this paper proposes a haptic shared control framework for teleoperation based on a force-constrained supervisory controller.

: This study aimed to evaluate the location of retinal fractal dimension (FD) abnormalities in individuals with diabetes mellitus (DM) and hypertension (HTN) without retinopathy. The annular zone of 6 mm × 6 mm OCTA images centered on the fovea was partitioned into thin annuli and analyzed using fractal analysis to measure FDs. The cohort ( = 114) had an average age of 55.
