摘要:

Purpose.To describe a patient with keratitis caused byCapnocytophaga canimorsusafter traumatic injury with a cat's tooth.Methods.Case report and review of the literature.Results.Sixteen months after onset of infection, the patient regained 20/30 vision in the affected eye. However, he required 7 months of antibiotic therapy to eliminate the infection.Conclusion.C. canimorsuskeratitis may follow penetrating corneal injury and wound contamination with cat saliva and may be recalcitrant to topical antibiotic therapy.

摘要:

Purpose.To report clinical and laboratory findings of bilateral corneal involvement in a patient with epidermolysis bullosa acquisita.Methods.A 25-year-old man with a history of progressive and painless loss of vision in both eyes presented to our service with bilateral corneal involvement: peripheral corneal perforation in one eye and advanced corneal thinning in the other eye. There was concomitant dermatologic bullous disease. Clinical and laboratory exams were analyzed.Results.The patient was diagnosed as having epidermolysis bullosa acquisita. Therapeutic corneal patch graft and conjunctival resection with cryotherapy were done, with satisfactory results.Conclusion.Bilateral corneal involvement in epidermolysis bullosa acquisita is described. To the best of our knowledge, this is the first description of such a case. Surgical management of the ocular findings associated with systemic therapy with colchicine seems to be a good therapeutic option in the management of this defying disease.

摘要:

Purpose.A case of inferior corneal thinning and high astigmatism with features of keratoconus in a patient with long-standing ocular rosacea is described.Methods.Axial curvature mapping was performed with the Tomey TMS-1 videokeratoscopy instrument and corneal thickness mapping was performed with the Orbscan Corneal Topography System (CTS). Tear clearance was assessed by measuring the concentration of fluorescein in the tear fluid with a fluorometer.Results.There were inferior corneal thinning and opacification in both eyes. Tear fluorescein clearance was markedly delayed in the right eye. There was asymmetric inferior corneal steepening in both eyes with I-S values of 1 in the right eye and 5.9 in the left eye. There were 5.9 diopters of astigmatism at 85 degrees in the right eye and 7.3 diopters of astigmatism at 73 degrees in the left eye. Corneal pachymetry mapping with the Orbscan CTS showed a normal central corneal thickness and maximal thinning in the inferotemporal periphery of the right cornea and inferonasal periphery of the left cornea.Conclusion.Chronic ocular rosacea can produce inferior corneal thinning and high astigmatism with some features of keratoconus. The inferior pattern of thinning in rosacea may be related to chronic exposure of the inferior cornea to inflammatory and matrix-degrading factors in the inferior tear meniscus.

摘要:

Purpose.To report a patient with consecutive Descemet's membrane (DM) detachments after successive phacoemulsification, review other reported patients with bilateral DM detachments, and explore the possibility of anatomic predisposition to DM detachment in some patients.Methods.Our patient's course was reviewed along with the reported experience with three other patients with bilateral DM detachments.Results.No clear underlying etiology of DM detachment was found in our patient or any of the other three reported patients reviewed.Conclusions.Some patients may be anatomically predisposed to DM detachment possibly because of an abnormality in the fibrillary stromal attachment to DM. Early postoperative surgical intervention often leads to satisfactory visual results.
