ABSTRACT
Purpose@#We report seven cases of first occurrence of dendritic keratitis associated with contact lens wear without previous keratitis history, based on a literature review. Those cases were finally diagnosed and treated as herpes virus keratitis. @*Methods@#Among patients who visited the ophthalmology outpatient clinic over two years, patients with dendritic corneal lesions associated with contact lens wear were included. Authors performed the diagnosis, treatment and the clinical follow up. @*Results@#Seven Patients with dendritic corneal lesions after wearing contact lens were diagnosed by history taking, clinical findings and molecular biological methods and were observed over the course of treatment. @*Conclusions@#For patients with dendritic keratitis after wearing contact lenses, there is a possibility of herpes keratitis rather than the common lesions associated with non-infectious corneal infiltration or keratitis caused by bacteria and fungus. It is necessary to observe those eyes thoroughly in respect to the exact past history taking, diagnosis by molecular-biological method as well as clinical features and the response to empirical antiviral agents.
ABSTRACT
Purpose@#To report two cases of keratoconjunctivitis induced by gingko nut contact.Case summary: These cases report two old patients with severe keratoconjunctivitis who had recently touched ginkgo nuts and then the periorbital area and eyes. In both patients, slit lamp examination found severe chemosis and corneal edema with moderate Descemet membrane folding. Specular microscopy showed diffuse damage of endothelial cells in acute stage of the disease. The patients were treated with oral and topical steroid and antihistamine over two weeks and showed slow recovery. @*Conclusions@#Contact with ginkgo nut can induce severe keratoconjunctivitis to the periorbital area. Special caution is recommended when after contacting ginkgo nuts.
