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.

Contrast Sensitivity Deficits and Its Structural Correlates in Fuchs Uveitis Syndrome.

Purpose: To investigate the deficits in contrast sensitivity in patients with Fuchs uveitis syndrome (FUS) and to explore the potential relationship between contrast sensitivity and ocular structure.

Methods: In this prospective study, 25 patients with FUS and 30 healthy volunteers were recruited. Eyes were divided into three groups: FUS-affected eyes (AE), fellow eyes (FE), and healthy eyes.

Risk factors for epiretinal membrane in eyes with primary rhegmatogenous retinal detachment that received silicone oil tamponade.

Background/aims: This study investigated the risk factors for epiretinal membrane (ERM) in eyes with primary rhegmatogenous retinal detachment (RRD) that received silicone oil (SO) tamponade.

Methods: This retrospective analysis included 1140 patients (1140 eyes) with RRD who underwent primary vitrectomy and SO tamponade. The prevalence of ERM was estimated and possible risk factors (eg, type 2 diabetes, proliferative vitreoretinopathy (PVR), SO tamponade time (SOTT), photocoagulation, vitreous haemorrhage, choroidal detachment, cryotherapy and retinal tear size) were analysed via multiple logistic regression.

Outcomes of a novel bubble ultra-wide field viewing system for vitreoretinal surgery.

Purpose: To report the clinical outcomes and evaluate the efficacy of a novel bubble ultra-wide field viewing system for vitreoretinal surgery.

Design: Prospective, noncomparative, interventional case series.

Participants: One hundred and fifty-one eyes of 146 consecutive patients with proliferative diabetic retinopathy (PDR), vitreous haemorrhage originating from retinal vein occlusion (VH-RVO), epiretinal membrane (EM), macular hole (MH) or retinal detachment (RD) who underwent vitreoretinal surgery using the bubble ultra-wide field viewing system were included.

Foveal microstructure and visual outcomes of myopic macular hole surgery with or without the inverted internal limiting membrane flap technique.

Purpose: The aim of this study was to determine the effect of the inverted internal limiting membrane (ILM) flap technique on the macular hole (MH) closure and foveal microstructure recovery of patients with highly myopic MH.

Methods: Pars plana vitrectomy and gas tamponade with the inverted ILM flap technique (19 eyes) or with the ILM peeling technique (21 eyes) were performed in patients with highly myopic MH with or without retinal detachment. The rate of MH closure and retinal reattachment, the reconstructive anatomical change of the foveal microstructure and the best-corrected visual acuities (BCVA) of the two groups were compared.

Chondrosarcoma of the Osseous Spine Treated by Surgery With or Without Radiotherapy: A Propensity Score Matched and Grade/Stage-stratified Study.

Study Design: This was a longitudinal cohort study.

Objective: The main objective of this study was to investigate the outcomes of surgery with or without radiotherapy during treatment of patients with chondrosarcoma of the osseous spine.

Summary Of Background Data: Chondrosarcoma is a primary spinal malignant tumor; chemotherapy and radiotherapy (RT) are generally unsuccessful, and thus, the main treatment of choice is complete en bloc resection.

[Short-term observation of Acrysof Toric intraocular lens for correction of preoperative astigmatism in patients having cataract surgery].

Objective: To evaluate the results of Toric intraocular lens (IOL) for correction of preoperative astigmatism in patients having cataract phacoemulsification.

Methods: It was a prospective case series study. Seventy-one eyes (60 patients) had implantation of Acrysof Toric IOL.

[Comparison of visual acuity in pseudophakic eyes with multifocal intraocular lens versus fellow eyes with clear lens].

Objective: To evaluate the visual acuity and subjective satisfaction of different aged monocular cataract patients who were implanted with ReSTOR multifocal intraocular lens (MIOL).

Methods: Prospective comparative study: the objects are 24 cases of monocular cataract patients who consecutively received phacoemulsification and implantation of ReSTOR MIOL. The patients were divided into two groups by age: the presbyopic group has 17 cases with age ≥ 45 years, the non-presbyopic group has 7 cases with ages < 45 years.

[Repair of scars in submaxillary region using expanded forehead axial flaps with fascia pedicles carrying bilateral frontal branches of superficial temporal artery and vein].

Objective: To study the feasibility of applying expanded forehead axial flaps with fascia pedicles carrying bilateral frontal branches of superficial temporal artery and vein (expanded forehead axial flap with double pedicles in brief, EFAF-DP) in repairing scars in submaxillary region.

Methods: Sixteen patients with mandibular scars hospitalized in Department of Burns and Plastic Surgery of the First Hospital Affiliated to Fuzhou General Hospital in Nanjing Military Area Command from July 2005 to December 2009 were repaired with EFAF-DP. The operation consisted of 3 stages.

[Repair of cervicofacial scar by forehead expansive skin flap double-pedicled with superficial temporal vessels].

Objective: To explore the clinical efficacy of using forehead expansive skin flap double-pedicled with superficial temporal vessels for repairing male cervicofacial scar.

Methods: From July 2005 to June 2009, 13 male patients with an average age of 27 years old (range: 21 - 38) were operated by the above method. The scar-repairing area was from 14 cm × 5 cm to 32 cm × 15 cm.

[Change in plasma brain natriuretic peptide and its clinical significance in burn patients after delayed fluid resuscitation of shock].

Objective: To observe the early change in plasma brain natriuretic peptide (BNP) level in burn patients with long delayed fluid resuscitation of burn shock and its clinical significance.

Methods: Thirty-six burn patients with second and third degree of burn covering 32%-92% total body surface area were enrolled for the study, among them 10 patients were complicated with serious heart failure (heart failure group), and 26 patients rallied from shock after delayed fluid resuscitation without heart failure (stable group). The level of plasma BNP, lactate dehydrogenase (LDH), MB isoenzyme of creatine kinase (CK-MB), and left ventricle ejection fraction (LVEF) were determined at admission and 3 hours after hospitalization, and 24, 48, 72, 168 hours after the injury in both groups with electrochemiluminescence (ECL).

[Relative factors of retinal detachment after phacoemulsification cataract extraction and intraocular lens implantation].

Objective: To investigate the incidence and related factors of retinal detachment (RD) after phacoemulsification cataract extraction and intraocular lens (IOL) implantation in an unselected patient group.

Methods: This retrospective review was comprised of 10 076 cataract patients (13 625 eyes) who had phacoemulsification cataract extraction and IOL implantation from December 1, 1998 to September 30, 2008. The patients were of different ages, gender, left or right eye and different type of cataracts.
