The Corneal Ulcer—II The Diagnosis of Corneal Ulceration
Journal of Small Animal Practice, 1966Abstract— The diagnosis of corneal ulceration is discussed and illustrated. Examination of the cornea and the clinical signs of ulceration are discussed.Résumé— La diagnose de l'ulcération de la cornée est discutée et illustrée. Des examens de la cornée et des signes cliniques d'ulcération sont discutés.Zusammenfassung— Die Diagnose über ...

Mechanisms of corneal ulceration
Ophthalmology Clinics of North America, 2002Corneal ulceration is a significant cause of visual morbidity. Although this discussion has primarily focused on the local factors involved in non-immune related sterile corneal ulcerations, an understanding of these mechanisms is important since a final common pathway that is conceivably relevant to all forms of corneal ulceration exists. With respect

Helminthosporium Corneal Ulcers
American Journal of Ophthalmology, 1978We studied four cases of Helminthosporium corneal ulcers from four different institutions. One case occurred in an immune-deficient infant, another in a patient three months after removal of a foreign body; the third case occurred in a patient with a corneal dystrophy who was wearing soft contact lenses and using topical corticosteroids; and the fourth

In a series of 162 bacterial corneal ulcers, 27 were culture positive for anaerobic organisms. Applying strict microbiologic criteria, 11 ulcers were determined to be due to anaerobic infection. No morphologic characteristic was identified to distinguish anaerobic from other types of corneal ulcers. All of the anaerobic ulcer patients manifested one or

Collagenase in Corneal Ulcerations
Archives of Ophthalmology, 1969Collagenase activity was found in the corneal epithelium of ten cases of corneal diseases associated with either acute or chronic corneal ulcerations. Sixteen cases, which included autopsy corneas, nondiseased corneas, and diseased corneas wihout ulcerations failed to reveal detectable activity.

Noninfected Corneal Ulceration
International Ophthalmology Clinics, 1984The pathogenesis of noninfected corneal ulcers consistently relates to persistent or extensive epithelial defects, concomitant with stromal inflammatory cell infiltration and enzymatic degradation of collagen and ground substance. The therapeutic approaches to these disorders may be considered on three levels: (1) determination of etiology and ...

A patient sustained a corneal abrasion from organic material, used an antibioticcorticosteroid ointment, and developed a corneal ulcer. The common contaminant Pullularia pullulans was isolated from corneal scrapings on two separate occasions. Topical amphotericin B application was ineffective despite in vitro sensitivity.

To the Editor. —I work in an area of the world where fungus corneal ulcers are common. The results of treatment have been uniformly disappointing. Despite vigorous treatment (including cautery with carbolic acid, silver nitrate, and iodine, and antifungal agents such as amphotericin B, nystatin, and clotrimazole), the ulcer usually progresses ...

Community Care of Corneal Ulcers
American Journal of Ophthalmology, 1992Because of increasing concern about the appropriate and cost-effective use of eye care services and procedures, several organizations have sought to arrive at practice guidelines or practice patterns from which physicians can draw guidance. To assess the potential effectiveness of such guidelines, we reviewed the care of patients with corneal ulcers ...

Corneal cross-linking in the treatment of corneal ulcers
Current Opinion in Ophthalmology, 2016New treatments for corneal ulcers are needed to address challenges with antibiotic resistance, cost, and specificity requiring timely pathogen identification. This review assesses the evidence regarding safety and efficacy of corneal cross-linking (CXL) as an adjunct or stand-alone treatment.To date approximately 200 clinical cases of CXL used with ...
