Purpose: To report our experience in non-contact wide-angled visualization with chandelier-assisted scleral buckling (SB) in uncomplicated primary rhegmatogenous retinal detachments (RRD).
Methods: Retrospective case series of 282 eyes that underwent non-contact wide-angled visualization with chandelier-assisted SB and were followed for a mean of 13.5 months.
Background: To assess closure rate after a single surgery of large macular holes and their visual recovery in the short term with three different surgical techniques.
Methods: Prospective multicenter randomized controlled trial. We included treatment-naïve patients with diagnosis of large macular hole (minimum diameter of > 400 µm).
Background: To assess the sensitivity, specificity, positive predictive value and negative predictive value of anterior chamber tap for the diagnosis of bacterial endophthalmitis on a population with high prevalence.
Methods: Retrospective, single centre, case series study. We reviewed all medical records with clinical diagnosis of bacterial endophthalmitis in our hospital from January 1st, 2000 to December 31st 2014.

We reviewed all the available data regarding the current management of non-complex rhegmatogenous retinal detachment and aimed to propose a new decision-making algorithm aimed to improve the single surgery success rate for mid-severity rhegmatogenous retinal detachment. An online review of the Pubmed database was performed. We searched for all available manuscripts about the anatomical and functional outcomes after the surgical management, by either scleral buckle or primary pars plana vitrectomy, of retinal detachment.

After the 4-year mark, visual acuity tends to return to pretreatment level. Treatment delays and lack of awareness and self-referral by the patients are believed to be the cause of the PRN regimen failure.

Methods: Eighteen New Zealand white rabbits were divided into three treatment groups (groups 1 to 3) and different intravitreal doses of quinupristin/dalfopristin were tested in each group. The right eye was injected with the drug and the left eye received intravitreal injection of 5% dextrose water and served as control eye.
The purpose of this study is to determine baseline vitreous humor temperature during a combined phacoemulsification and pars plana vitrectomy (PPV) procedure; to determine what is the temperature variation during phacoemulsification; and to compare vitreous temperature to sublingual temperature. The methods used are prospective, interventional and comparative study. Patients with a diagnosis of cataract and vitreous hemorrhage, programed for a combined procedure of phacoemulsification and PPV, were included.

Methods: A prospective, interventional, noncomparative case study. The primary outcome measure was visual acuity.
Background: Perfluorocarbon liquid (PCL)-perfused vitrectomy has been shown in previous studies to be feasible, safe, and to have advantages in managing complicated cases of tractional retinal detachment. The present study had the objectives of describing the anatomical results and measuring surgical time and PCL consumption when combining PCL-perfused techniques with modern vitrectomy equipment.
Methods: A prospective, interventional consecutive case series was investigated.
Purpose: To measure vitreous, aqueous, subretinal fluid and plasma levels of vascular endothelial growth factor in late stages of retinopathy of prematurity.
Methods: Interventional study. We enrolled patients with clinical diagnoses of bilateral stage V retinopathy of prematurity, confirmed by b-scan ultrasound and programmed for vitrectomy.
Background And Objective: To assess the effect of laser fluence reduction to reduce pain during panretinal photocoagulation.
Patients And Methods: Twenty-five patients (50 eyes) with diabetic retinopathy who had indication for panretinal photocoagulation were included in this prospective, interventional, and comparative study. The right eyes were treated using low fluence parameters (LFP), whereas the left eyes were treated with standard fluence parameters (SFP).
Background/aims: The pattern scan laser photocoagulator (PASCAL) is a novel laser device that uses 10-30 ms pulse duration for retina photocoagulation. The aim of this study was to analyse the safety profile of this approach.
Methods: This was a retrospective study.
Purpose: To assess the short-term complications of a single dose of intravitreal bevacizumab in patients with proliferative diabetic retinopathy (PDR).
Methods: Retrospective review of 343 patients with PDR who were treated with intravitreal injection of bevacizumab (2.5 mg/0.
Retinal pathological angiogenesis is the leading cause of visual loss in a wide variety of ocular diseases. Some of the examples include: Age-related macular degeneration, diabetic retinopathy and retinopathy associated with prematurity. These last two entities are, in addition, public health problems in developing countries.
View Article and Find Full Text PDFBackground: Central retinal vein occlusion (CRVO) is a common retinal vascular disorder with potentially complications: (1) persistent macular edema and (2) neovascular glaucoma. No safe treatment exists that promotes the return of lost vision. Eyes with CRVO may be predisposed to vitreous degeneration.

Two patients with refractory end-stage glaucoma who had no light perception underwent pars plana vitrectomy and lamina cribrosa puncture to relieve pain and decrease intraocular pressure. The patients presented with blind, painful eyes and high intraocular pressure (> 40 mm Hg). After the procedure, the pain was relieved and the intraocular pressure was lowered in both cases.
View Article and Find Full Text PDFPurpose: To present a new concept and technique for subretinal surgery.
Methods: Twenty-four eyes of 24 patients with subfoveal choroidal neovascularization (CNV) were included in this study. Nine patients were operated on in Mexico City by one surgeon, 15 patients in Frankfurt by another surgeon.
Purpose: To investigate the feasibility and advantages of using perfluorocarbon liquid (PCL) perfusion to remove vitreous during suction-cutting vitrectomy in rabbit and pig eyes.
Design: Experimental study.
Methods: Balanced salt solution (BSS) was replaced by PCL perfusion during experimental vitrectomy.

Background And Objective: To evaluate the effectiveness of a new method of delivering diode laser (810 nm) spots through an indirect ophthalmoscope in conjunction with intravenous indocyanine green to treat choroidal neovascularizations (CNVs) larger than 5,400 microm.
Patients And Methods: A prospective, non-comparative, interventional case series study was conducted with 8 patients with CNV secondary to age-related macular degeneration. Laser pulses were applied to the CNV within 5 minutes of an intravenous injection of 25 mg of indocyanine green.
Purpose: To report the spontaneous resolution of a traumatic macular hole that was considerably larger than in previously reported cases.
Design: Observational case report.
Methods: The clinical and angiographic data of the patient were reviewed.
