摘要:

Purpose.To report on a patient with a clinical presentation of annular crystalline keratopathy after immunoglobulin therapy for pyoderma gangrenosum.Methods.Case report of a 6-year-old boy with biopsy-proven history of pyoderma gangrenosum who had undergone several cycles of systemic immunoglobulin therapy. The literature on ocular manifestations associated with pyoderma gangrenosum was reviewed.Results.One year after the last cycle, the patient complained of the sudden onset of photophobia. Slit-lamp biomicroscopy revealed bilateral symmetric crystalline deposits in an annular region of the cornea. Because visual acuity was not reduced, specific therapy was not initiated. Symptoms could be reduced by the prescription of medical edged filter lenses.Conclusions.Annular crystalline corneal deposits may be associated with immunoglobulin therapy or represent a hitherto unknown ocular complication of pyoderma gangrenosum.

摘要:

Purpose.To report a case of direct contact xylene-related vacuolar keratopathy.Methods.Interventional case report and review of the literature.Results.Xylene keratopathy is a distinct clinical entity characterized by significantly decreased visual acuity, increased corneal thickness, and the presence of corneal epithelial and stromal vacuoles on a diffuse gray stromal background. The vacuoles are diffusely scattered, subtle, and clear on slit-lamp examination. Occasionally, white, round, denser areas can also be observed. Xylene keratopathy disappeared gradually over 4 weeks with topical steroid treatment and did not cause permanent sequelae.Conclusions.Xylene exposure should be considered as possible etiologic agent of vacuolar epithelial and stromal keratopathy. Exposure may occur directly as a splash of liquid or through its vapors.
