PURPOSE Large macular holes usually have an increased risk of surgical failure. Up to 44% of large macular holes remain open after 1 surgery. Another 19% to 39% of macular holes are flat-open after surgery. Flat-open macular holes are associated with limited visual acuity. This article presents a modification of the standard macular hole surgery to improve(More)
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(More)
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(More)

This master thesis investigates the possibilities of using Suffix Tree Clustering (STC) algorithm to clustering search results in the Polish language as obtained from Web search engines. This work indicates possible problems arising when documents in language of complex inflection and syntax are being clustered. We also share the results of our observations(More)
Histamine (HI) is present in all studied ocular (retina, choroid, optic nerve) and brain structures of the albino rabbit. HI levels in neural eye elements (retina and optic nerve) are relatively low, i.e 70–140 ng/g tissue, and comparable with those found in the brain; a typical vascular tissue, i.e. choroid, contained approximately 10 times more HI.(More)
The aim of this paper is to evaluate the retinal structure after macular hole surgery and to study the correlation of structural findings with final functional outcomes, using high-speed, high-resolution spectral optical coherence tomography (SOCT). Sixty-eight eyes of 60 patients with full-thickness macular holes were included in the study. All patients(More)
Preretinal membrane formation is a frequently diagnosed disease in ophthalmology. Its pathogenesis is unclear. Optical coherence tomography is an important diagnostic tool in patients with epiretinal membranes. In our study we use high-speed and high-resolution spectral OCT. Our goal was to present different forms of ERM and to analyze the influence of some(More)
To report on changes in retinal morphology during the 12 months after macular hole surgery. Seventy one eyes of 66 patients after pars plana vitrectomy with ILM peeling and air tamponade were evaluated with spectral OCT for 12 months and additionally before surgery. Macular hole size was measured. On consecutive visits, the size of photoreceptor layer(More)
PURPOSE To report choroidal thickness and volume in healthy eyes using swept source optical coherence tomography (SS-OCT). METHODS A prospective observational study of 122 patients examined with swept source OCT (DRI-OCT, Topcon, Japan). In each eye, we performed 256 horizontal scans, 12 mm in length and centered on the fovea. We calculated choroidal(More)
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. Twenty-six eyes of 26 patients with lamellar macular hole were diagnosed using spectral domain optical coherence tomography (SD- OCT). The(More)
