PURPOSE To test the hypothesis that keratoconus and pellucid patients who have glaucoma or are suspected of having glaucoma have lower corneal hysteresis (CH) and/or corneal resistance factor (CRF) measurements compared to controls. METHODS A prospective study at a tertiary eye center of keratoconus and pellucid patients with glaucoma or suspected of having glaucoma, and age-matched keratocon...

Background: In spite of the great advances in vitrification, the mechanism of embryo damage which occure in some cases and varies from one case to another case is not exactly understood. Since Zona pellucida has an important role on early embryonic development, the aim of the present study is to investigate the effect of vitrification on integrity of zona pellucida and surveillance of blastocys...

The main aim of the Pellucid project is to develop a platform based on the multi-agent technology for assisting public employees in their organization. This paper deals with one of many problems associated with building such a system. There is the problem of classification and identification of required information for agent’s performance. Pellucid agents use historical experience and informati...

RATIONALE Terrien's marginal corneal degeneration (TMD) is characterized by progressive peripheral corneal thinning. It appears primarily above the age of 40 years and is rare at younger ages. Spontaneous corneal perforation in TMD is a rare, but serious complication that may occur in childhood. PATIENT CONCERNS This review presents the case of a 16-year-old girl presented with blurred vision...

PURPOSE To report the long-term clinical outcome of a patient diagnosed as having Terrien marginal degeneration (TMD) who was subjected to corneal collagen cross-linking (CXL) with ultraviolet-A and riboflavin in both eyes. METHODS Topographical changes were assessed by high-resolution Scheimpflug imaging and anterior segment optical coherence tomography. Eccentric epithelium-off CXL was perf...

PURPOSE We report a case of Terrien's marginal degeneration (TMD) with a unilaterally typical narrow band of peripheral corneal stroma thinning, accompanied by the presence of an unusual network of opacities diffusing throughout the anterior stroma layers. CASE REPORT A 43-year-old woman presented with superior nasal peripheral corneal thinning and an unusual network of polygonal stromal opac...

In 1937 Bietti reported a tapetoretinal degeneration with associated corneal deposits at the limbus. The hallmark of the disease was the crystalline characteristics of the retinal spots as well as those at the corneal limbus. Bagolini and Ioli-Spade in 1968 presented a 30 year follow-up on Bietti's cases and presented six additional cases. The present report delas with this entity in Orientals,...

Abstract This paper is a survey focuses on seven basic Voting Methods for Preferential Ballots. The purpose to give pellucid illustration of these in consideration Game Theory, and understand their intrinsic associative properties. In order efficacy, multiple techniques, such as Mathematical Modeling Computer Programming, are used evaluation comparison. ultimate goal find which elect the most d...
