Congenital coralliform cataract is the predominant consequence of a recurrent mutation in the CRYGD gene.

Background: Congenital cataract is a leading cause of treatable childhood blindness and both clinically and genetically heterogeneous. Among the already characterized phenotypes, coralliform cataract is a rare special form of congenital cataracts. Although previous studies had shown that mutations in the γD-crystallin (CRYGD) can result in congenital coralliform cataracts, no conclusive genotype-phenotype correlation might be drawn.

Effects and Prognosis of Cataract Surgery in Patients with Retinitis Pigmentosa.

Introduction: Cataract extraction could improve visual acuity (VA) for patients with retinitis pigmentosa (RP), while the surgery may increase photoreceptor degeneration through light damage. In this study, we conducted a systematic review and meta-analysis to investigate the effectiveness and prediction of VA after cataract surgery in patients with RP.

Methods: We comprehensively extracted data from literature of available studies with quality control processing.

cGAS inhibition alleviates Alu RNA-induced immune responses and cytotoxicity in retinal pigmented epithelium.

Background: The degeneration of retinal pigmented epithelium (RPE) cells results in severe diseases, such as age-related macular degeneration (AMD) that causes blindness in millions of individuals.

Results: We report that targeting GMP-AMP (cGAMP) synthase (cGAS) alleviates Alu RNA-induced immune responses and cytotoxicity in RPE. We find that the deletion of cGAS in RPE inhibits the Alu RNA-stimulated interferon production.

Vault changes and pupillary responses to light in myopic and toric implantable collamer lens.

Background: Achieving an appropriate vault is the main concern after the implantation of Implantable Collamer Lens (ICLs) for surgical correction of high myopia. The vault will vary with time and optical parameters, such as accommodation and pupil size. This research is to evaluate the vault change in Myopic and Toric ICLs under different lighting conditions; and to analyze the relationship between vault changes and pupillary responses to light.

NIR-triggered drug delivery system for chemo-photothermal therapy of posterior capsule opacification.

Posterior capsule opacification (PCO) is the most common complication after cataract surgery and is likely to cause the second loss of vision. Pharmacological PCO prophylaxis has been proved to be effective, yet no clinical option is available due to the lack of a suitable mode of administration. In this work, we propose a unique concept of NIR dual-triggered drug release from black phosphorus (BP)-based implantable intraocular lens (IOL) for controlled drug release and chemo-photothermal combination therapy of PCO.

A novel F30S mutation in γS-crystallin causes autosomal dominant congenital nuclear cataract by increasing susceptibility to stresses.

Despite of increasingly accumulated genetic variations of autosomal dominant congenital cataracts (ADCC), the causative genes of many ADCC patients remains unknown. In this research, we identified a novel F30S mutation in γS-crystallin from a three-generation Chinese family with ADCC. The patients possessing the F30S mutation exhibited nuclear cataract phenotype.

CuInS/ZnS quantum dots modified intraocular lens for photothermal therapy of posterior capsule opacification.

Posterior capsule opacification (PCO) after cataract surgery is one of the leading causes of visual impairment and blindness. The cause of PCO is the capsule fibrosis developed on implanted Intraocular Lens (IOLs) by the de-differentiation of Lens Epithelial Cells (LECs) undergoing epithelial mesenchymal transition. How to prevent PCO has been a challenge to scientists and ophthalmologists for decades.

TGF-β regulation of microRNA miR-497-5p and ocular lens epithelial cell mesenchymal transition.

The purpose of this study was to investigate the role of a human lens microRNA (miR-497-5p) in regulating epithelialmesenchymal transition (EMT) under the control of transforming growth factor beta (TGF-β). A microRNA array was used to evaluate the microRNA profiles of untreated and TGF-β-treated human lens epithelial cells in culture. This showed that TGF-β treatment led to the upregulation of 96 microRNAs and downregulation of 39 microRNAs.

Repeatability and agreement of two anterior segment OCT in myopic patients before implantable collamer lenses implantation.

Aim: To evaluate the intra-operator repeatability of time domain and swept-source Fourier domain anterior segment optical coherence tomography (AS-OCT), namely, Visante AS-OCT and Casia SS-1000 OCT, in measuring the preoperative parameters of implantable collamer lens (ICL) in myopic eyes, as well as the agreement between the two devices.

The purpose of the present study was to analyze the clinical phenotypes of a girl with oculo-facio-cardio-dental (OFCD) syndrome and to identify the potential pathogenic mutation responsible for her disease.

Mutation analysis of the candidate gene BCOR was performed with polymerase chain reaction and Sanger sequencing.

Retinal vascular injuries and intravitreal human embryonic stem cell-derived haemangioblasts.

Objective: To investigate whether intravitreally applied haemangioblasts (HB) derived from human embryonic stem cells (hESCs) are helpful for the repair of vascular damage caused in animals by an oxygen-induced retinopathy (OIR), by an induced diabetic retinopathy (DR) or by an induced retinal ischaemia with subsequent reperfusion.

[The progress of studies on intraocular lens implantation in cataract with high myopia].

With development of the technology of cataract surgery, combined phacoemulsification and intraocular lens implantation in cataract with high myopia has been widely carried out in clinical treatment. Due to the particularity of high myopia, phacoemulsification in patients with cataract and high myopia is difficult and has recently received a lot of attentions. In this paper, preoperative examinations, the selection of intraocular lenses, surgery methods and surgical complications of cataract surgery in patients with cataract and high myopia are briefly reviewed.
