oxidative stress in patients with epiretinal membrane.

Context: Oxidative stress is an important factor for vitreomacular interface disease development in a theoretical model.

Purpose: The aim of the study was to evaluate the correlation between oxidative stress in the human epiretinal membrane (ERM) and retinal morphological changes.

Material And Methods: The study included patients scheduled for vitrectomy with epiretinal membrane removal.

Recurrent Intraocular Lens Dislocation in a Patient with Familial Ectopia Lentis.

A 36-year-old patient presented to the hospital with recurrent dislocation of the intraocular lens (IOL). The patient with the diagnosis of familial ectopia lentis was first operated on for crystalline lens subluxation in the left eye in 2007 and in the right eye in 2009. In both eyes, lens extraction with anterior vitrectomy and transscleral fixation of a rigid IOL was performed.

The Most Common Lesions Detected by Neuroimaging as Causes of Epilepsy.

Epilepsy is a common neurological disorder characterized by chronic, unprovoked and recurrent seizures, which are the result of rapid and excessive bioelectric discharges in nerve cells. Neuroimaging is used to detect underlying structural abnormalities which may be associated with epilepsy. This paper reviews the most common abnormalities, such as hippocampal sclerosis, malformations of cortical development and vascular malformation, detected by neuroimaging in patients with epilepsy to help understand the correlation between these changes and the course, treatment and prognosis of epilepsy.

Optical coherence tomography angiography features in patients with idiopathic full-thickness macular hole, before and after surgical treatment.

Purpose: To present optical coherence tomography (OCT) angiography features in patients with idiopathic full-thickness macular hole before and after vitrectomy.

Study Design: Prospective case series study.

Materials And Methods: Patients presenting with an idiopathic full-thickness macular hole (IMH) who underwent posterior vitrectomy with internal limiting membrane peeling and gas tamponade were included in the study.

The gamma knife in ophthalmology. Part Two--Other ocular diseases.

Gamma Knife was designed by Lars Leksell in the early 1950's. It gave rise to a new discipline of medicine--stereotactic radiosurgery. Main use of Gamma Knife in ophthalmology--discussed in the first part of this paper--is non-invasive treatment of uveal melanoma.

The gamma knife in ophthalmology. Part One--Uveal melanoma.

The Gamma Knife was designed by Lars Leksell in the early 1950's. It gave rise to a new discipline of medicine--stereotactic radiosurgery. Primarily dedicated to neurosurgery, the Gamma Knife has become an alternative, widely used surgery technique.
