Aqueous levels of VEGF correlate with retinal non-perfusion areas in patients with diabetic macular edema and macular edema secondary to central retinal vein occlusion.

Aim: To evaluate the association between the level of vascular endothelial growth factor in the aqueous humor and the size of capillary non-perfusion areas in patients with macular edema secondary to retinal vein occlusion and diabetic retinopathy.

Material And Methods: The study group consisted of 24 patients (24 eyes) at the age of 55-78 years, with diffuse macular edema secondary to retinal vein occlusion and diabetic retinopathy. The control group consisted of 26 subjects aged 55-87 years who were admitted for scheduled cataract surgery.

[Elevated level of circulating endothelial cells as an exponent of chronic vascular dysfunction in the course of AMD].

Purpose: In recent years, emerging data support the concept of endothelial dysfunction in the course of age-related macular degeneration (AMD). Circulating endothelial cells (CECs) are desquamated mature cells that have detached from the intimal monolayer in response to endothelial injury. In this study we sought to explore the potential role of endothelial dysfunction in pathogenesis of AMD by measuring the concentration of CECs in peripheral blood of AMD patients.

[Usefulness of electrophysiological tests in the evaluation of retinotoxicity and treatment efficacy of intravitreal bevacizumab (avastin) injection in some eye diseases].

Purpose: The goal of our study is to present on the basis of the current literature the value of electrophysiological tests in the evaluation of retinal toxicity and clinical efficacy of bevacizumab intravitreal injection.

Material And Methods: Intravitreal toxicity of bevacizumab in rabbits and isolated vertebrate retinas FVEP and ERG were used for testing. Electrophysiological tests in animals were performed according to own laboratory methods.

[Transconjunctival sutureless vitrectomy (TSV)].

The purpose of this study is to present, on the basis of the current literature, the actual state of knowledge on the subject of microvitrectomy: surgery technique, indications, contraindications, potential benefits and possible complications. Introduced in 2002, 25-gauge, transconjunctival sutureless vitrectomy (TSV) becomes more popular surgical technique, which can replace in many cases standard 20-gauge vitrectomy. Recent study results indicate, that TSV is effective and safe surgery technique which is characterized by shorter surgery time, reduction of postoperative inflammation and faster rehabilitation in comparison to 20-gauge vitrectomy.

Visual function and late complications after cataract surgery by phacoemulsification with primary posterior capsulotomy and intracapsular foldable intraocular lens implantation.

Purpose: Evaluation of visual function and late complications after cataract phacoemulsification with primary posterior capsulotomy and intracapsular foldable intraocular lens implantation in 22-months follow-up.

Material And Methods: Twenty five eyes of 25 patients (mean age: 53 years) were included in the study. All the eyes underwent primary posterior thermal capsulotomy and in-the-bag foldable IOL (Acrysof) implantation.

[Use of applicator AMO PhacoFlex II SofTip Insertion System in cataract surgery with IOL implantation].

Purpose: To evaluate the clinical use of the unfolder in cataract surgery with foldable IOL implantation.

Material And Method: Forty eyes of 40 patients were analysed. In all patients cataract phacoemulsification was performed.
