We investigate the existence of Intrinsic Localized Modes (ILMs) in nonlinear one-dimensional KleinGordon chains. We use the Lagrangian averaging approach parameterizing ILM by several slow-varying variables, and apply the averaging directly in the action principle. Our preliminary studies yield results for ILM dynamics in accordance with those obtained by other methods.

BACKGROUND Myopic foveoschisis (MF) is among the leading causes of visual loss in high myopia. However, it remains controversial whether internal limiting membrane (ILM) peeling or gas tamponade is necessary treatment option for MF. METHODS PubMed, EMBASE, CBM, CNKI, WANFANG DATA and VIP databases were systematically reviewed. Outcome indicators were myopic foveoschisis resolution rate, visua...

AIMS To investigate the ultrastructure of the vitreoretinal interface in patients with vitreomacular traction syndrome. METHODS 14 patients with vitreomacular traction syndrome underwent standard pars plana vitrectomy. After induction of posterior vitreous detachment, epiretinal tissue and the inner limiting membrane (ILM) of the retina were removed, and processed for transmission electron mi...

Purpose: To evaluate the efficacy and safety of combined phacoemulsification and 23gauge pars plana vitrectomy with Brilliant blue-G (BBG)-assisted ILM peeling in idiopathic macular hole surgery with closure of the hole by an inverted ILM flap. Design: Prospective and interventional case series. Methods: 23 eyes with large (>400 μm) idiopathic macular hole treated by phacoemulsification with po...

BACKGROUND To evaluate the efficacy of internal limiting membrane (ILM) peeling in the treatment of a macular hole. METHODS The ocular evaluation included Snellen visual acuity, a slit-lamp examination, indirect ophthalmoscopy, and contact lens biomicroscopy. The macular holes were confirmed using a Watzke-Allen slit beam test. Surgery consisted of a standard 3-port vitrectomy under local ane...

BACKGROUND The purpose of this study was to describe and evaluate a surgical approach, known as internal limiting membrane (ILM) peeling, as an adjunct to repair of recurrent retinal detachment due to proliferative vitreoretinopathy (PVR). METHODS This was a retrospective case series. All eyes underwent repair of recurrent PVR-related rhegmatogenous retinal detachment incorporating macular in...

PURPOSE To investigate the incidence of and risk factors for a dissociated optic nerve fiber layer (DONFL) after epiretinal membrane surgery. METHODS Two hundred and ninety-six primary pars plana vitrectomy operations for epiretinal membrane that were eligible for inclusion in the study. All patients received a complete ophthalmologic examination and color fundus photography, optical coherenc...

The topographic distribution of fibronectin and laminin in young and old human eyes was determined by indirect immunofluorescent techniques. These two glycoproteins may play a role in the attachment of the vitreous to the internal limiting membrane (ILM) and the internal limiting membrane to the Mueller cell processes. A double-laminated pattern of fluorescence for both glycoproteins was freque...

We reduce the complex mechanics of an Intrinsic Localized Mode (ILM) on an infinite monodirectional nonlinear coupled oscillator array. By using Hamiltonian Mechanics, we derive two systems – a simple case when only the position of the ILM is allowed to vary, and the more complex case where both position and amplitude are allowed to change with time. We arrive at a systems of nonlinear equation...

A static bar is perceived to dynamically extend from a peripheral cue (illusory line motion, ILM) or from a part of another figure presented in the previous frame (transformational apparent motion, TAM). We examined whether visibility for the cue stimuli affected these transformational motions. Continuous flash suppression, one kind of dynamic interocular masking, was used to reduce the visibil...
