Case report: Advanced modified pneumatic retinopexy for treating simultaneous bilateral rhegmatogenous retinal detachment.

Background: Simultaneous bilateral rhegmatogenous retinal detachment (RRD) is a rare and challenging condition in ophthalmology. This case report focuses on a modified pneumatic retinopexy technique, designed to improve treatment outcomes for this difficult condition.

Case Presentation: A 59-year-old male presented with decreased visual acuity in his right eye for one week.

Metabonomics analysis of aqueous humor samples from cataract patients with branch retinal vein occlusion.

Cataract (CAT) has a very high incidence rate among the middle-aged and elderly, with most patients complicated by branch retinal vein occlusion (BRVO), a key cause of blindness. In this study, through metabolomic analysis of aqueous humor samples from CAT patients with BRVO, a total of 319 different metabolites were found, most of which belonged to the categories of carboxylic acids and derivatives, fatty acyls, and organooxygen compounds. The most typical metabolites were 3-methylhistidine and biliverdin, which were up-regulated, as well as the down-regulated beta-glycerophosphoric acid.

Pneumatic Retinopexy Involving the Use of Intravitreal Air Injection and Laser Photocoagulation for Rhegmatogenous Retinal Detachment in Phakic Eyes.

The clinical efficacy of pneumatic retinopexy (PR) using intravitreal pure air injection and laser photocoagulation for rhegmatogenous retinal detachment (RRD) remains unknown. Thirty-nine consecutive patients with RRD (39 eyes) were included in this prospective case series. All patients underwent two-step PR surgery containing pure air intravitreal injection and laser photocoagulation retinopexy during hospitalization.

The cholinergic system, intelligence, and dental fluorosis in school-aged children with low-to-moderate fluoride exposure.

Disruption of cholinergic neurotransmission can affect cognition, but little is known about whether low-to-moderate fluoride exposure affects cholinergic system and its effect on the prevalence of dental fluorosis (DF) and intelligence quotient (IQ). A cross-sectional study was conducted to explore the associations of moderate fluoride exposure and cholinergic system in relation to children's DF and IQ. We recruited 709 resident children in Tianjin, China.

Retinoschisis: A Predictive Factor in Vitrectomy for Lamellar Macular Holes in Highly Myopic Eyes.

Purpose: To evaluate the effect of pars plana vitrectomy (PPV) and internal limiting membrane (ILM) peeling for lamellar macular hole (LMH) with or without macular retinoschisis in highly myopic eyes.

Methods: In this retrospective, consecutive case-control study, 21 highly myopic patients (22 eyes) with LMH were divided into two groups based on preoperative optical coherence tomography (OCT): the "flat group" had no macular retinoschisis (n = 10), and the "retinoschisis group" had macular retinoschisis (n = 12). The average follow-up time was 17.

Effects of miRNA-200b on the development of diabetic retinopathy by targeting gene.

The present study explored the effect of on the development of diabetic retinopathy (DR) by targeting vascular endothelial growth factor A () gene. The study populations consisted of 255 DR patients (case group) and 253 healthy people (control group), while the expressions of and VEGFA mRNA were detected by quantitative real-time PCR (qRT-PCR). Bioinformatics software and dual-luciferase reporter assay were used to confirm as a target gene of Also, a total of 70 Wistar male rats were selected and randomly assigned into blank, normal control (NC), mimics, inhibitors, inhibitors + silencing vascular endothelial growth factor A (siVEGFA), and siVEGFA groups (=10/group) respectively.
