Comparison of complications of intrascleral fixation according to the extent of vitrectomy.

Background: Intraocular lens (IOL) fixation is performed after intraoperative anterior or total vitrectomy. This study aimed to compare the intraoperative and postoperative complications of these two techniques.

Methods: This retrospective study included 235 eyes that underwent intrascleral fixation surgery at our hospital between July 2014 and January 2021.

Modified capsule expander implantation to reposition and fixate the capsular bag in eyes with subluxated cataractous lenses and phacodonesis: intermediate-term results.

Purpose: To report the intermediate-term results of capsule stabilization for scleral fixation with implantation of the Yaguchi hook, a modified capsule expander stabilization hook.

Setting: Department of Ophthalmology, School of Medicine, University of Showa, Fujigaoka Rehabilitation Hospital, Yokohama, Japan.

Design: Retrospective case series.

Rap1 GTPase activation and barrier enhancement in rpe inhibits choroidal neovascularization in vivo.

Loss of barrier integrity precedes the development of pathologies such as metastasis, inflammatory disorders, and blood-retinal barrier breakdown present in neovascular age-related macular degeneration. Rap1 GTPase is involved in regulating both endothelial and epithelial cell junctions; the specific role of Rap1A vs. Rap1B isoforms is less clear.

Myopic refractive shift represents dense nuclear sclerosis and thin lens in lenticular myopia.

Background: It is not rare to meet unilateral nuclear sclerotic cataracts with myopic refractive changes (lenticular myopia) compared with the fellow eye in the ophthalmic examination of patients with decreased visual acuity. To determine the relationship between the myopic refractive changes and interocular differences of parameters, we investigated the interocular differences of ocular parameters between a lenticular myopic eye and the fellow eye.

Method: This retrospective study included 68 eyes of 34 patients, who showed unilateral lenticular myopia.

Periostin, discovered by nano-flow liquid chromatography and mass spectrometry, is a novel marker of diabetic retinopathy.

Diabetes can lead to serious microvascular complications including proliferative diabetic retinopathy (PDR), the leading cause of blindness in adults. Recent studies using gene array technology have attempted to apply a hypothesis-generating approach to elucidate the pathogenesis of PDR, but these studies rely on mRNA differences, which may or may not be related to significant biological processes. To better understand the basic mechanisms of PDR and to identify potential new biomarkers, we performed shotgun liquid chromatography (LC)/tandem mass spectrometry (MS/MS) analysis on pooled protein extracts from neovascular membranes obtained from PDR specimens and compared the results with those from non-vascular epiretinal membrane (ERM) specimens.

[Evaluation of post intraocular lens implantation detrition of clear corneal incisions using an injector system in porcine eyes].

Purpose: To evaluate the detrition of clear corneal incisions (CCIs) after intraocular lens (IOL) implantation using an injector system in porcine eyes.

Methods: Group A: after CCIs were performed with 1.8, 2.

Capsular stabilization device to preserve lens capsule integrity during phacoemulsification with a weak zonule.

We describe a new capsular stabilization device for suspending a lens with weak zonular support. It is flexible, 10.0 mm in length, and fashioned from 5-0 nylon.

Lens epithelial cell migration between posterior capsule and intraocular lens with variously finished posterior optic edge and two haptic angulations.

Purpose: To compare lens epithelial cell migration between intraocular lens (IOL) optics and the posterior capsule of IOLs with various edges and haptic angulations.

Methods: Experimental acrylic IOLs with 3 types of finishing (none, polishing, tumbling and polishing) and 2 types of haptic angulation (10 and 15 degrees ) as well as 3 (AcrySof MA30BA, Sensar AR40, CeeOn 911) clinically implanted IOLs were inserted in rabbit eyes. Scanning electron-microscopic examination of IOLs was carried out before surgery and histological examination of lens capsules 3 weeks after surgery.
