PURPOSE To report the prevalence of postoperative retinal tear or rhegmatogenous retinal detachment secondary to intravitreal injections. METHODS Surgical and medical records of patients who received intravitreal injections at the practice of a single retina specialist from January 2004 to May 2013 and who were followed for at least 6 months were investigated retrospectively. RESULTS During...

Introduction: Posterior segment retained Intraocular foreign body (IOFB) management is challenging. Facility of pars plana vitrectomy (PPV) and availability well trained vitreo retina surgeons are the basic need to accomplish this work. Encircling band provide permanent 360° support close anterior retinal break prevent traction on retina. The objective study analyse clinical characteristics pre...

purpose : to report a case of congenital macular macrovessels case report : an 8-year-old girl was referred for decreased vision in her right eye. her best corrected visual acuity (bcva) in the right eye was 20/200 and in the left eye 20/20. anterior segment examinations were normal in both eyes. posterior segment examination of the right eye showed abnormal macrovessels crossing the macula and...

Introduction Blue light is a part of the spectrum with the highest energy content, which can reach the retina. The damage that it can cause to the retina is called photochemical or blue-light retinal injury. For the retinal injury assessment of the photochemical and aphakic retinal hazards in the wavelength range of 300-700 nm, use of effective spectral radiance limits (W.m-2.sr-1) seems to be...

BACKGROUND Trans-pars plana vitrectomy (TPPV) is an effective surgical procedure to retain the useful vision in vitreoretinal diseases. OBJECTIVE To evaluate the surgical outcome of pars plana vitreoretinal surgery. STUDY DESIGN Retrospective non-comparative interventional case series. MATERIALS AND METHODS A hospital-based retrospective interventional study of series of cases was carried...

PURPOSE To modify existing experimental models to simulate the typical clinical presentation of human rhegmatogenous retinal detachment (RRD), namely an RD caused by a retinal break, in a phakic eye, with a posterior vitreous detachment (PVD); to model RRD in a species that is anatomically similar to humans; and to characterize the glial cell response to RRD. METHODS Mixed-breed pigs underwen...

The eye generally is considered to be an immune-privileged organ, but this notion is being increasingly challenged as ocular antigens can be expressed in the generative lymphoid organs, resulting in attainment of self-tolerance. What triggers a break in this tolerant state is a fundamental question in autoimmunity research. The general belief is that exposure to environmental microbes can break...

The climbing fibers (CFs) that project from the dorsal cap of the inferior olive (IO) to the flocculus of the cerebellar cortex have been reported to be purely sensory, encoding "retinal slip." However, a clear oculomotor projection from the nucleus prepositus hypoglossi (NPH) to the IO has been shown. We therefore studied the sensorimotor information that is present in the CF signal. We presen...
