Nomogram for predicting non-proliferative vitreoretinopathy probability after vitrectomy in eyes with rhegmatogenous retinal detachment.

Aim: To identify the risk factors for postoperative proliferative vitreoretinopathy (PVR) in patients with primary rhegmatogenous retinal detachment (RRD) and develop a nomogram for predicting postoperative PVR-free probability.

Methods: A total of 741 patients (741 eyes) diagnosed with primary RRD who underwent first surgery in the same hospital were retrospectively reviewed and randomly assigned with 521 to the training set and 220 to the validation set. Univariate and multivariate logistic regression analyses were performed in the training cohort to determine risk factors to construct a nomogram for predicting the 3-, 4-, 5-, and 6-month postoperative PVR-free probabilities.

Intraocular lens-blocking technique for intraocular foreign body removal.

The aim of this study was to describe a novel technique for intraocular foreign body (IOFB) removal. Phacoemulsification was performed in all patients, followed by a complete microincision vitrectomy to free all tissues surrounding the IOFB. A three-piece intraocular lens (IOL) was placed in the capsular bag, and an opening was made in the upper center of the capsule.

Reversed scleral tunnel technique for repair of iridodialysis after blunt force trauma: a retrospective clinical study.

Background: To investigate the efficacy and safety of reversed scleral tunnel technique for repairing iridodialysis after blunt force trauma.

Methods: A total of 51 eyes of 51 patients with iridodialysis undergoing surgery were included in this study. Patients were divided into 2 groups: group A (the reversed scleral tunnel technique) and group B (the control group).

Suturing technique for scleral fixation of toric intraocular lens in the traumatic aphakic eye with corneal astigmatism.

Purpose:: To describe the clinical outcomes of traumatic aphakic eyes with corneal astigmatism after using a novel technique for toric intraocular lens suture fixation.

Methods:: In total, 12 eyes of 12 patients who underwent a new scleral suture fixation technique of one-piece toric intraocular lens (SN6AT series, Alcon Inc., TX, USA) were included in our retrospective study.

Treatment of Bacillus cereus endophthalmitis with endoscopy-assisted vitrectomy.

To evaluate the use of endoscopy-assisted vitrectomy in patients with sight-threatening Bacillus cereus endophthalmitis.A retrospective analysis was conducted in 15 eyes with Bacillus cereus endophthalmitis. Patients were divided into 2 groups: endoscopy-assisted vitrectomy (5 eyes) and conventional vitrectomy (10 eyes).

Potential role of Cyr61 induced degeneration of human Müller cells in diabetic retinopathy.

The degeneration of Müller cells has been recognized to involve in the pathogenesis of diabetic retinopathy. However, the mechanism is not yet clear. This study is to explore the potential role of Cyr61, a secreted signaling protein in extracellular matrix, in inducing human Müller cell degeneration in diabetic retinopathy (DR).

Sutureless vitrectomy incision architecture in the immediate postoperative period evaluated in vivo using optical coherence tomography.

Purpose: To investigate the in vivo sutureless vitrectomy incision architecture using optical coherence tomography (OCT) in the immediate postoperative period.

Design: Prospective, observational case series.

Participants: Thirty-five patients underwent 3-port pars plana vitrectomy using 23-gauge instrumentation combined with 25-gauge infusion at the Wenzhou Eye Hospital.
