AIM Investigation of the natural history of trachomatous trichiasis in the Gambia and of the outcome of self epilation and surgery for the condition. METHODS A 1 year longitudinal study of 190 subjects with trichiasis was performed. Major trichiasis cases (five lashes or more) were referred for surgery and minor trichiasis cases were advised to epilate. Outcome measures included progression o...
PURPOSE This study aimed to evaluate the effectiveness of phototherapeutic keratectomy (PTK) as an alternative treatment to keratoplasty using the Pentacam to assess depth of dense opacities. METHODOLOGY PTK was performed in eleven eyes of ten patients with superficial corneal opacities after assessment by Scheimpflug images of the Pentacam for central corneal thickness (CCT) and opacity leve...
A 31-year-old man presented to our clinic for an ocular trauma to his left eye. His best-corrected visual acuity was 20/200 OS (left eye). Anterior segment examination showed an epithelial defect, which implies a direct injury to the cornea. A marked focal stromal edema accompanied by Descemet's membrane folds were located at 10 o'clock in the paraxial area, about 4 mm apart from the corneal ce...
FK506 binding protein 12 (FK506BP) is a small peptide with a single FK506BP domain that is involved in suppression of immune response and reactive oxygen species. FK506BP has emerged as a potential drug target for several inflammatory diseases. Here, we examined the protective effects of directly applied cell permeable FK506BP (PEP-1-FK506BP) on corneal alkali burn injury (CAI). In the cornea, ...
PURPOSE To determine if paraproteinemic keratopathy (PPK) in the setting of monoclonal gammopathy of undetermined significance (MGUS) causes distinct patterns of corneal opacification that can be distinguished from hereditary, immunologic, or inflammatory causes. METHODS A retrospective, interventional study of patients showed distinct bilateral opacity patterns of the cornea at the eye clini...
INTRODUCTION Severe ocular trauma requires emergency surgery, and a fresh corneal graft may not always be available. We describe a case of perforating eye injury with corneal opacity, suspected endophthalmitis, and an intraocular foreign body. The patient was successfully treated with a two-step procedure comprising endoscopy-guided vitrectomy followed by corneal transplantation. This surgical ...
purpose : vitreoretinal surgery can be difficult or impossible in patients with corneal opacity. one solution for this problem is use of temporary keratoprosthesis (tkp). we report anatomical and visual outcomes of this combined surgery in our institution. methods : we retrospectively reviewed charts of patients in whom a tkp was used between 2006 and 2010 with follow-up of at least six months....
To fabricate donor corneal substitutes based on carbodiimide cross-linked porcine collagen, to study their in vitro and in vivo properties, and to elaborate new implantation techniques for the donor corneal collagen-based substitutes, this study had been performed. Bioengineered substitutes of corneal stroma (BSCS) were fabricated by cross-linking porcine type I collagen with 1-ethyl-3-(3-dimet...
KERATITIS associated with a line of opacity within the cornea is a peculiar condition which has been included as an interstitial keratitis by Duke-Elder and Leigh (1965). It was first reported by Fuchs (1926) as keratitis linearis migrans, and the literature was enlarged and summarized by Wright (1963). The characteristic feature is a line of granular opacity which elongates at each end while m...
