Comparison of polypropylene and silicone Ahmed® glaucoma valves in the treatment of neovascular glaucoma: A 2-year follow-up.

Background: Inflammation associated with biomaterials of Ahmed® glaucoma drainage devices may cause the formation of a capsule around the device and can thus have a significant influence on the level of intraocular pressure reduction.

Objectives: The objective of this study was to compare the clinical outcomes after the implantation of a polypropylene or silicone Ahmed® glaucoma valve in patients with neovascular glaucoma.

Material And Methods: In the study, 27 eyes with neovascular glaucoma (group 1) received silicon Ahmed® valves and 23 eyes (group 2) received polypropylene valves.

Assessment of macular function, structure and predictive value of pattern electroretinogram parameters for postoperative visual acuity in patients with idiopathic epimacular membrane.

Purpose: To evaluate macular function and structure before and after epimacular membrane surgery and to estimate the usefulness of pattern ERG test parameters in predicting the postoperative visual acuity.

Methods: We evaluated 32 eyes of 32 patients (mean age 70.8 ± 6.

The role of outdoor activity in the development of myopia in schoolchildren.

Introduction: The aim of our study was to examine whether outdoor activity influences the prevalence of myopia in schoolchildren.

Materials And Methods: 5601 Polish students of elementary and secondary schools (2688 boys and 2913 girls), 6–18 years of age (mean 11.9 ±3.

PARS PLANA VITRECTOMY IN ADVANCED CASES OF VON HIPPEL-LINDAU EYE DISEASE.

Purpose: To investigate spectrum of patients with Von Hippel-Lindau disease (VHL) that required pars plana vitrectomy and evaluate anatomical and functional outcomes of surgery.

Methods: Twenty-three patients who underwent surgery for advanced VHL eye disease were assessed by genetic tests, diagnostic tests for systemic lesions, and clinical eye examination. The vitrectomized eyes were divided into two groups: with or without retinotomy (group R vs.

Does the month of birth influence the prevalence of refractive errors?

Purpose: The aim of our study was to examine whether the month of birth influences the prevalence of refractive errors.

Material And Methods: A total of 5,601 schoolchildren were examined (2,688 boys and 2,913 girls, aged 6-18 years, mean age 11.9, SD 3.

[Outcomes of surgical management of retinopathy of prematurity--an overview].

According to the guidelines by the ETROP (Early Treatment for Retinopathy of Prematurity) study group, laser therapy is the gold standard in the treatment of retinopathy of prematurity. However, progression of the disease is seen in 12% of eyes despite the treatment. Since there is no causal treatment, new therapies of retinopathy of prematurity, are continually sought, such as anti-VEGF agents, beta-blockers, or insulin-like growth factor gene therapy.

Present-day conservative treatment retinopathy of prematurity.

Retinopathy of prematurity occurs in prematurely born babies. Etiology of disease is multifactorial and frequency of retinopathy of prematurity diagnosis increases. Retinopathy is one of causes for major loss of vision and amaurosis in newborns around the world.

[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.

Potential application of adult stem cells in retinal repair--challenge for regenerative medicine.

Stem cells (SCs) maintain the balance among somatic cell populations in various tissues and are responsible for organ regeneration. The remarkable progress of regenerative medicine in the last few years indicates promise for the use of SCs in ophthalmic disorder treatment. This review describes the current view on hierarchy in the SC compartment and presents the latest attempts to use adult SCs in the regeneration of the retina.

[Neuroprotection in glaucoma].

The aim of this research is to describe one of the most frequent ophthalmology disease-glaucoma and to look at their neurodegenerative nature and methods to stop disease. We use neuroprotection in glaucoma from a short time but despite of ethiological reasons neuroprotection seems to be one of the main mechanism to slow their progression. This research is talking about new opinions about neuroprotection in glaucoma and their epidemiology and etiology.

[Objective retinal nerve fiber laser assessment by scanning laser polarimetry in patients with chiasmal compression].

Purpose: To assess the evaluation ability of retinal nerve fiber layer (RNFL) in patients with visual tracts' compression and to assess the correlation between visual field loss and changes in RNFL.

Material And Methods: Polarimetric RNFL analysis (scanning laser polarimeter- NFA/GDx, software version 1.0.

[Evaluation of retinal nerve fiber thickness with scanning laser polarimetry in patients with anterior ischemic optic neuropathy].

Purpose: To measure retinal nerve fiber layer thickness (RNFL) in patients with anterior ischemic optic neuropathy (AION) by scanning laser polarimetry and to asses the correlation between RNFL thickness and perimetric indices in AION eyes.

Material And Methods: Polarimetric RNFL analysis (scanning laser polarimeter- NFA/GDx, software version 1.0.

[Retinal nerve fiber layer analysis and evaluation of eye blood flow in patients with glaucoma].

Purpose: The aim of this research was to evaluate the changes of blood flow velocity in ocular arteries (ophthalmic artery, central retinal artery and short posterior ciliary arteries) and the amount of ocular nerve fibers in patients with primary open angle glaucoma (POAG) and normal tension glaucoma (NTG).

Material And Method: The research was done on 17 patients with diagnosed POAG and 13 patients with NTG. No ocular surgery was performed on any of these patients prior to our examinations.
