Transcriptomic analysis of plasma-derived small extracellular vesicles reveals the pathological characteristics of normal tension glaucoma.

Aim: Normal tension glaucoma (NTG) is a common optic neuropathy that can be challenging to diagnose due to the intraocular pressure remaining within the normal range. Early diagnosis and intervention are crucial for the effective lifelong management of patients.

Methods: This study recruited a total of 225 participants.

Circulating Small Extracellular Vesicles Involved in Systemic Regulation Respond to RGC Degeneration in Glaucoma.

Glaucoma is a leading cause of irreversible blindness worldwide and is characterized by progressive retinal ganglion cell (RGC) degeneration and vision loss. Since irreversible neurodegeneration occurs before diagnosable, early diagnosis and effective neuroprotection are critical for glaucoma management. Small extracellular vesicles (sEVs) are demonstrated to be potential novel biomarkers and therapeutics for a variety of diseases.

The effect of corneal power on the accuracy of 14 IOL power formulas.

Background: This study evaluates the impact of corneal power on the accuracy of 14 newer intraocular lens (IOL) calculation formulas in cataract surgery. The aim is to assess how these formulas perform across different corneal curvature ranges, thereby guiding more precise IOL selection.

Methods: In this retrospective case series, 336 eyes from 336 patients who underwent cataract surgery were studied.

Comparison of deep learning-assisted blinking analysis system and Lipiview interferometer in dry eye patients: a cross-sectional study.

Background: Abnormal blinking pattern is associated with ocular surface diseases. However, blink is difficult to analyze due to the rapid movement of eyelids. Deep learning machine (DLM) has been proposed as an optional tool for blinking analysis, but its clinical practicability still needs to be proven.

A Period of Macular Hyperemia and Subclinical Edema Caused by Phacoemulsification Surgery in Noninfectious Uveitis.

Purpose: To identify the changes in macular microvasculature in uveitic patients following phacoemulsification.

Methods: A prospective cohort study was conducted by enrolling uveitic patients who underwent phacoemulsification at the Eye Hospital. Macular vessel densities (VD) of superficial and deep capillary plexus (SCP and DCP) and retinal thickness (RT) were quantified by optical coherence tomographic angiography (OCTA).

Substance P induces sympathetic immune response in the contralateral eye after the first eye cataract surgery in type 2 diabetic patients.

Background: Substance P (SP) is a nociceptive tachykinin which regulates the immune inflammatory reactions including monocyte chemoattractant protein 1 (MCP-1) production. Sequential second-eye cataract surgery patients often suffer more pain than the first one partly because of the MCP-1 increase in aqueous humor (AH). This study aims to illustrate whether SP is involved in sympathetic inflammatory responses in the contralateral eye in patients with or without type 2 diabetes.

Identification of whirlin domains interacting with espin: A study of the mechanism of Usher syndrome type II.

Usher syndrome is the most common condition of combined blindness and deafness and is classified into three types (USH1‑USH3). USH2 is the most commonly diagnosed of all Usher syndrome cases. There are three identified proteins (usherin, GPR98 and whirlin) that form the USH2 complex.

Elevated Plasma Levels of Drebrin in Glaucoma Patients With Neurodegeneration.

Glaucoma is an optic neuropathy characterized by progressive degeneration of retinal ganglion cells (RGCs). Aberrations in several cytoskeletal proteins, such as tau have been implicated in the pathogenesis of neurodegenerative diseases, could be initiating factors in glaucoma progression and occurring prior to axon degeneration. Developmentally regulated brain protein (Drebrin or DBN1) is an evolutionarily conserved actin-binding protein playing a prominent role in neurons and is implicated in neurodegenerative diseases.

Phacoemulsification With 3.0 and 2.0 mm Opposite Clear Corneal Incisions for Correction of Corneal Astigmatism.

Purpose: To compare the effect of 3.0 and 2.0 mm opposite clear corneal incisions (OCCIs) in phacoemulsification on reduction of preexisting corneal astigmatism, and their impact on corneal aberrations.

Circulating S100A8/A9 Levels Reflect Intraocular Inflammation in Uveitis Patients.

To investigate whether there is an association between circulating S100A8/A9 levels and uveitis activity. A total of 549 plasma samples were collected from uveitis patients and non-uveitic controls. S100A8/A9 plasma levels were elevated in uveitis patients compared to non-uveitic controls ( < 0.

Long-term outcomes of ciliary sulcus versus capsular bag fixation of intraocular lenses in children: An ultrasound biomicroscopy study.

Purpose: To evaluate the long-term outcomes of ciliary sulcus versus capsular bag fixation of intraocular lenses (IOLs) in children after pediatric cataract surgery.

Methods: IOL was implanted in the ciliary sulcus in 21 eyes of 14 children, and in the capsular bag in 19 eyes of 12 children for the treatment of pediatric cataract in an institutional setting. Ultrasound biomicroscopy (UBM) was performed.

The long-term anterior segment configuration after pediatric cataract surgery and the association with secondary glaucoma.

Secondary glaucoma constitutes major sight-threatening complication of pediatric cataract surgery, yet the etiology remains unclear. The purpose of this study was to investigate the long-term anterior segment configuration and the association with secondary glaucoma in pediatric pseudophakia. Ultrasound biomicroscopy (UBM) was performed on 40 eyes of 26 children underwent pediatric cataract surgery and intraocular lens (IOL) implantation.

[Comparison of effects of secondary in-the-bag and sulcus intraocular lens implantation in pediatric aphakia after congenital cataract operation].

Objective: To compare the results of secondary in-the-bag intraocular lens (IOL) implantation with secondary sulcus IOL implantation in the eyes which received cataract extraction during early infancy.

Methods: A case control study. We selected 60 eyes of 44 patients with pediatric aphakia that meet the inclusion criterion in Affiliated Eye Hospital of Wenzhou Medical College from September 2005 to August, 2011.

Visual and optical performance of eyes with different corneal spherical aberration implanted with aspheric intraocular lens.

Aim: To compare the visual and optical performance of eyes with different corneal spherical aberration (SA) implanted with spherical aberration-free intraocular lens (IOLs).

Methods: Thirty-six patients with different corneal SA had phacoemulsification with implantation of spherical aberration-free IOLs. Patients were divided into 3 groups according to the value of preoperative corneal SA.
