Purpose: To report a case of posterior keratoconus with atypical ocular findings Case report: An 8-year-old boy was referred to our clinic with the chief complaint of blurred vision in his right eye. The patient had no history prior ocular surgery of trauma. Her family history was also unremarkable. Comprehensive ocular examination was performed. Results: The patient's best spectacle corrected ...

Purpose To assess the comparability and repeatability of keratometric and astigmatism values measured by four techniques: Orbscan IIz® (Bausch and Lomb), Lenstar LS 900® (Haag-Streit), Cassini® (i-Optics), and Total Cassini (anterior + posterior surface), in healthy volunteers. Patients and methods Fifteen healthy volunteers (30 eyes) were assessed by the four techniques. In each eye, three c...

AIMS To map the thickness, elevation (anterior and posterior corneal surface), and axial curvature of the cornea in normal eyes with the Orbscan corneal topography system. METHODS 94 eyes of 51 normal subjects were investigated using the Orbscan corneal topography system. The anterior and posterior corneal elevation maps were classified into regular ridge, irregular ridge, incomplete ridge, i...

Purpose: To evaluate anterior surface topographic technologies and display algorithms in mapping keratoconus. Materials and methods: A total of 27 eyes of 17 subjects clinically diagnosed with keratoconus were imaged on six topographers: EyeSys, Alcon EyeMap, Keratron, TMS-1, Orbscan and PAR corneal topography system. Axial distance (AD) and instantaneous radius of curvature (IROC) algorithms w...

In the global village of today, more people have been moving and migrating than ever before creating a need for better communication. Thus community interpreting rose as a specialization serving the needs of members of the community who are unable to communicate with the system. Within this broad field of interpreting the specialist area of legal interpreting assumed a high position. However, l...

Abstract This paper presents an alternative epistemic worldview of the corporate responsibility to respect human rights (CR2R) as a norm. It examines how Afrocentric interpretation CR2R norm can contribute relational system where corporations promote in African host communities. uses — Ubuntu reframe and reinterpret Pillar II terms. argues that this reframing is important for three reasons.
