Objective: To examine the clinical phenotype and genetic deficiencies present in Chinese aniridia families with PAX6 haplotype deficiency.
Methods: A comprehensive questionnaire and ophthalmological assessments were administered to both affected patients and unaffected relatives. The clinical feature analysis included the evaluation of visual acuity, intraocular pressure, slit-lamp anterior segment examination, fundus photography, and spectral domain optical coherence tomography.
In insects, chemosensory proteins (CSPs) play an important role in the perception of the external environment and have been widely used for protein-binding characterization. Riptortus pedestris has received increased attention as a potential cause of soybean staygreen syndrome in recent years. In this study, we found that RpedCSP4 expression in the antennae of adult R.

Methods: A retrospective, nonrandomized, comparative case series was conducted. Patients with CACG who underwent phaco in combination with either ECP alone (ECP group) or GSL with ECP (E-GSL group) from 2018 to 2019 were followed for 12mo and reviewed.
Cataract is the leading cause of blindness worldwide. In order to achieve large-scale cataract screening and remarkable performance, several studies have applied artificial intelligence (AI) to cataract detection based on fundus images. However, the fundus images they used are original from normal optical circumstances, which is less impractical due to the existence of poor-quality fundus images for inappropriate optical conditions in actual scenarios.

This was a retrospective, uncontrolled, interventional case series. All patients from 2016 to 2017 who received CLASS were recruited in this study.

The aim of the present study was to identify the underlying cause of ARS in a Chinese family. Genomic DNA was extracted from the peripheral blood of the subjects from a family with ARS.

Currently, mesenchymal stem cells (MSCs) could restore I/R-injured retina through paracrine secretion. Additionally, heme oxygenase-1 (HO-1) could ameliorate oxidative stress and thus retinal apoptosis, but the expression of HO-1 in MSC is limited.

Purpose: The aim of this study is to examine whether or not myocilin (MYOC) genetic variations are associated with susceptibility to primary angle-closure glaucoma (PACG) in the Han Chinese population.
Methods: Four single-nucleotide polymorphisms (SNPs)-rs235913, rs183532, rs12076134, and rs235875-in the MYOC gene were genotyped in 212 adult patients with PACG and 255 age-, sex-, and ethnic-matched healthy controls by using a polymerase chain reaction-restriction fragment length polymorphism assay. Data were analyzed by chi-square analysis.

Objective: To investigate the relationship between glaucoma and Moscow Eye Microsurgery Complex (Moroz) keratoprosthesis.
Methods: Analysis and retrospective review of consecutive clinical case series. A total of 90 patients had a Moroz keratoprosthesis implantation between Apr, 2000 and Jun, 2011 at our hospital.
Aim: To investigate the characteristics and criterion of graft rejection in mice model.
Methods: C57BL/6 or BALB/c mice corneal grafts were grafted onto BALB/c hosts. Each group was divided into two subgroups according to the corneal opacity scores 12d after transplantation.
Objective: To study the cell membrane of corneal endothelium with a micromolecular compound J2 in corneal allograft of rat using atomic force microscopy (AFM).
Methods: Cohort study. Subjects were divided into two groups: group A (n = 15): experimental group; group B (n = 15): placebo control group.

Aim: To construct a Foxp3 lentiviral vector and transfer it into DC2.4 cells, which provides Foxp3+DC cells for further study on its immune modulation.
Methods: We cloned mouse Foxp3 gene into lentiviral vector(pGC-FU) and acquired the plasmid pGC-FU-Foxp3.
Background: The aim of this study was to investigate the mechanisms underlying tolerance induction of dexamethasone (Dex)-treated dendritic cells (DCs).
Material/methods: Well-grown DC2.4 cells were randomly assigned to receive control, 50 µg/L, 100 µg/L, or 200 µg/L of dexamethasone and then were cultured for 6 days.

Objective: To evaluate the efficacy, predictability, stability, and safety of the surgical correction myopia using implantable Collamer lenses (ICL) in phakic eyes.
Methods: A prospective study was performed to analyze 91 eyes of 48 patients who had the implantation of ICL for the treatment of myopia from July 2008 to February 2010. Patients were examined preoperatively and followed at 1 week, 1, 3, 6, and 12 months postoperatively.
Objective: To discuss the mechanism of J2 on preventing mice's corneal rejection.
Methods: In experimental study, Balb/c mice had been divided into A, B, C, D, E groups randomly. There were 13 mice in each of Group A, C and E, while 7 in both Group B and D.

Objective: To investigate the effects of J2 on the prevention of corneal allograft rejection in mice.
Methods: Randomized control design was applied. One hundred C57BL/6 and thirty eight BALB/c mice were used as donors and recipients, respectively, to establish a corneal allograft model.

Background: Frozen or dried corneal grafts are commonly used for stromal transplantation such as lamellar keratoplasty (full or partial thickness), keratophakia, epikeratophakia. Structural properties are important for the final optical results of these surgeries but the effects of freezing/thawing and drying/rehydration on the properties of the stroma are known little compared with the corneal endothelium, mainly because of lack of non-invasive technique to evaluate the stromal structure. This study aimed to investigate the swelling and structural properties of the bovine corneal stroma following freezing or drying by X-ray diffraction which was a non-invasive technique and could give ultra-structural information in hydrated tissues.
