Nanoparticles of chosen noble metals as reactive oxygen species scavengers.

Reactive oxygen species (ROS) play an important role in various physiological processes of living organisms. However, their increased concentration is usually considered as a threat for our health. Plants, invertebrates, and vertebrates including humans have various enzymatic and non-enzymatic defence systems against ROS.

[Treatment of cystoid macular edema with bevacizumab in course of Irvine-Gass syndrome].

Purpose: To determine clinical effect of intravitreal bevacizumab (Avastin) in patients with cystoid macular edema after cataract surgery.

Material And Methods: Four eyes of four patients treated with 1 intravitreal injection of 1.25 mg Avastin.

Long-term evaluation of vitreomacular traction disorder in spectral-domain optical coherence tomography.

Purpose: The aim of this article was to estimate the natural course of vitreomacular traction (VMT) disorder using high-resolution spectral-domain optical coherence tomography.

Methods: Nineteen eyes of 19 patients with idiopathic symptomatic VMT and who underwent spectral-domain optical coherence tomographic follow-up examinations were included in the retrospective observational study. The average observation period of all patients who underwent the examination was 8 months (±4.

Evolution from macular pseudohole to lamellar macular hole - spectral domain OCT study.

Background: The pathogenesis of macular pseudohole (MPH) is supposed to be different from that of macular lamellar hole (LMH). MPH is thought to be caused by centripetal contraction of previously present epiretinal membrane. LMH is considered to be an effect of abortive process of full-thickness macular hole formation, or a result of de-roofing of a foveal cyst in persistent cystoid macular oedema.

Surgical treatment of lamellar macular holes.

Background: The aim of this study is to present functional and anatomical results of pars plana vitrectomy without gas tamponade in lamellar macular holes. Additionally, the study determines factors influencing final outcome.

Methods: Twenty-six eyes of 26 patients with lamellar macular hole were diagnosed using spectral domain optical coherence tomography (SD-OCT).
