purpose. Visual sensations in patients with blindness and retinal degenerations may be restored by electrical stimulation of neurons implantable microelectrode arrays. A prospective trial was initiated to evaluate the safety efficacy a wireless intraocular implant (EPIRET3) six volunteers RP. methods. The is remotely controlled, fully device consisting receiver stimulator module. placed on surface. Data energy are transmitted via an inductive link from outside eye implant. Surgery included...
purpose. To analyze the occurrence of near infrared (NIR) fluorescence in relation to NIR reflectance, blue-light–excited autofluorescence, angiograms, and funduscopy. methods. Observational consecutive case series patients with macular diseases. Imaging was performed a confocal scanning laser ophthalmoscope for fluorescence, fluorescein indocyanine green (ICG) angiograms. In cases which observed, five nine images were averaged. The leakage analyzed. results. 291 eyes analyzed, observed 51...

<h3>Background</h3> It is unclear whether or not an additional encircling band improves outcome in vitrectomy for pseudophakic retinal detachment (PRD). Also small gauge transconjunctival trocar-guided as successful conventional 20 (G) vitrectomy. <h3>Methods</h3> 257 adult patients with uncomplicated PRD were enrolled 14 vitreoretinal centres across Germany. Contingent on availability of qualified surgeons, eligible randomly assigned either (i) ratio 1:1 to G plus (group E1) without any...
To test if an encircling band improves outcomes in vitrectomy for pseudophakic retinal detachment (PRD) with inferior or multiple (4 more) breaks. Subgroup analysis of a prospective randomized controlled multicenter trial patients uncomplicated PRD assigned either to 20 G plus (group E1), without any buckle C), 23/25 E2). The primary endpoint was defined as no indication retina reattaching procedure during the review period 6 months. One hundred out 257 were identified breaks and 63 had 4...
To examine the relationship between surgeon experience and success rates in retinal detachment surgery.Success during a follow-up of 11 months 8 surgeons who performed total 375 procedures ranging from 14 to 115 cases December 1997 January 2002 were correlated number vitreoretinal 176 2,587. All patients received either scleral buckling or vitrectomy, complicated excluded.Mean primary anatomical 0.69 ± 0.14 for 0.9 0.05 vitrectomy (P < 0.05). The did not correlate procedures.

Purpose . Most studies about retinal detachment cover a limited follow-up period. The purpose of this research is to assess the long-term results after pars plana vitrectomy (PPV) and scleral buckle (SB) surgery in patients with rhegmatogenous (RRD). Methods 155 RRD are treated either SB or PPV mean more than 5 years. Retrospective analysis patient data was performed between January 2006 June 2008 at tertiary eye clinic. Results Overall primary success rate 85.2% (PPV: 84.6%, SB: 89.5%;...
<h3>Purpose</h3> Scleral buckling is currently used in addition to vitrectomy for the treatment of pseudophakic retinal detachment (PRD) better support vitreous base and visualisation periphery. <h3>Aims</h3> The aims this study are evaluate (1) whether combination 20 G scleral superior alone (control) (confirmatory), (2) transconjunctival 23/25 non-inferior (both without buckling) regarding operation success (exploratory). <h3>Methods</h3> VIPER (Vitrectomy Plus Encircling Band Vs....
<h3>Aim:</h3> To assess the accuracy and signal quality of axial length measurements by partial coherence laser interferometry (PCI) for optical biometry in eyes with conventional silicone oil (SO) or heavy (HSO) as endotamponade. <h3>Methods:</h3> We included 26 SO endotamponade (SO, n = 15; HSO, 11) using a Zeiss IOLMaster measurement day before at least 6 weeks after removal. analysed intra-individual deviation between both signal-to-noise ratio (SNR) marker quality. 16 contralateral...
Abstract Purpose We assessed the accuracy of lens power calculation in highly myopic patients implanting plus and minus intraocular lenses (IOL). Methods included 58 consecutive, eyes with an axial length (AL) > 26.0 mm, undergoing phacoemulsification IOL implantation following biometry using IOLMaster 500. For calculation, Haigis formula was used all cases. comparison, refraction back-calculated Barrett Universal II (Barrett), Holladay I, Hill-RBF (RBF) SRK/T formulae. Results The mean...
To demonstrate development and complications in heavy silicone oil (HSO) surgery 100 eyes following primary vitreoretinal surgery.100 were included this retrospective study that underwent using HSO as endotamponade. Indication diagnoses retinal detachments (n = 76), complicated macular holes (MH) 20), others 4). removal was performed after a mean period of 20.2 ± 19.0 weeks. In 18 with poor functional prognosis the remained permanently for stabilisation. Overall follow-up time 35.9 51.8...
In addition to measurement errors, individual anatomical conditions could be made responsible for unexpected prediction errors in the determination of correct intraocular lens power cataract surgery. Obviously, such might relevant both eyes. The purpose this study was evaluate whether postoperative refractive error first eye has taken account biometry second.In retrospective study, we included 670 eyes 335 patients who underwent phacoemulsification and implantation a foldable According SRK/T...
Purpose: To determine ocular side effects of vardenafil with special regard to color vision and retinal function. Methods: This was a single center, randomized, double-blind, placebo-controlled, twofold crossover study an administration oral dose two 20 mg tablets BAY 38–9456 (vardenafil hydrochloride) or corresponding placebo in 24 healthy male subjects. Ocular investigations included Farnsworth–Munsell D100 test, electroretinogram, basic ophthalmological examinations like visual acuity,...
To investigate the relationship of ocular blood flow (via arteriovenous passage time, AVP) and contrast sensitivity (CS) in healthy as well normal tension glaucoma (NTG) subjects.Mono-center comparative prospective trial METHODS: Twenty-five NTG patients without medication 25 test participants were recruited. AVP a measure retinal was recorded via fluorescein angiography after CS measurement using digital image analysis. Association at 4 spatial frequencies (3, 6, 12, 18 cycles per degree,...
