PURPOSE The purpose of this work was to identify potential tear-film based proteins expressed in keratoconus. METHODS Recruited subjects were normal gas permeable (GP) contact lens wearers, keratoconus subjects wearing GP contact lenses, and keratoconus subjects without contact lenses. Subjects wearing soft lenses or having previous ocular surgeries were excluded from participating. Approxima...

AIM To study the survival and visual outcome of penetrating keratoplasty in an African setting. METHODS A retrospective analysis of 216 corneal grafts, performed on 203 eyes of 186 patients, at Kikuyu Hospital, Kenya over a 5 year period. RESULTS Half of the transplants were carried out for keratoconus with only 5% of the grafts being undertaken for corneal scarring caused by trachoma or me...

Abstract In recent years, driven by Industry 4.0 wave, academic research has focused on the science, engineering, and enabling technologies for intelligent cyber manufacturing. Using a network science data mining-based Keyword Co-occurrence Network (KCN) methodology, this work analyzes trends in topics manufacturing literature over past two decades to inform researchers, educators, industry lea...

PURPOSE To validate the estimation of corneal aberrations from videokeratography against a laser ray tracing technique that measured total eye aberrations, in eyes without keratoconus (ie, cornea-dominated wave aberrations). METHODS We measured total and corneal wave aberrations of three eyes diagnosed with keratoconus by slit-lamp microscopy and corneal topography: two eyes from one patient ...

PURPOSE To differentiate between keratoconus and contact lens-related corneal warpage by combining focal change patterns in anterior corneal topography, pachymetry, and epithelial thickness maps. METHODS Pachymetry and epithelial thickness maps of normal, keratoconus, and warpage, and forme fruste keratoconus (FFK) eyes were obtained from a Fourier-domain optical coherence tomography (OCT). E...

We report a familial case of keratoconus with corneal granular dystrophy. The mother and first son have both keratoconus and corneal granular dystrophy and the second son has keratoconus alone. The keratoconus in this family is thought to be an autosomal dominant or an X-linked inheritance pattern. Granular dystrophy is an autosomal dominant inheritance. This familial case suggests that the gen...

Objectives Comparison of topography and corneal higher order aberrations (HOA) data of fellow normal eyes of unilateral keratoconus patients with keratoconus eyes and control group. Materials and Methods The records of 196 patients with keratoconus were reviewed. Twenty patients were identified as unilateral keratoconus. The best corrected visual acuity (BCVA), topography and aberration data ...

A 23-year-old lady was referred to the cornea clinic complaining of progressive visual loss from 8 years ago. Uncorrected visual acuity (UCVA) was 20/100 in her right eye and 20/600 in the left one. She was using rigid gas-permeable (RGP) contact lenses for 4 years and complained of contact lens intolerance especially in her left eye. On slit lamp examination, both corneas were clear but Vogts’...

Introduction: There are many reports on the association of various psychiatric disorders with visual impairment. The dry eye syndrome depressive has been particularly well documented. In context keratoconus patients group, data similar relationships inconclusive. Attempts have also made to assess personality suffering from keratoconus, and first study in this area was produced as early 1976. Ma...

Measurements of respiration were made on leaf discs from glasshouse-grown soybean (Glycine max [L.] Merr. cv ;Corsoy') plants in the presence and absence of cyanide (KCN) and salicylhydroxamic acid (SHAM). O(2) uptake by mature leaves measured at 25 degrees C was stimulated by 1 millimolar KCN (63%) and also by 5 millimolar azide (79%). SHAM, an inhibitor of the alternative oxidase and a select...
