The effect of a new antiherpetic compound of very low toxicity called acycloguanosine (Wellcome 248U) on herpetic ulcers in rabbit cornea was studied by the Corneal Epithelial Lesion Therapeutic Assay (CELTA). The therapeutic effect of 3% acycloguanosine ointment on dendritic ulcers was equal to that of 0.5% 5-iodo-2'-deoxyuridine (IDU) ointment. No toxic symptoms could be detected by slit-lamp...

PURPOSE We report a case of methicillin-resistant Staphylococcus aureus (MRSA) keratitis after Descemet's stripping automated endothelial keratoplasty (DSAEK). CASE REPORT An 87-year-old woman who had undergone a DSAEK 4 months previously was referred to Tokushima University Hospital with a diagnosis of infectious keratitis after DSAEK. A white abscess and infiltration in the inferior cornea ...

PURPOSE To evaluate the incidence, severity, and factors related to drug-induced keratoepitheliopathy in eyes using antiglaucoma eye drops. PATIENTS AND METHODS In a cross-sectional study, 749 eyes from 427 patients who had used one or more antiglaucoma eye drops were examined at Niigata University Medical and Dental Hospital or related facilities. The incidence and severity of superficial pu...

The results of a histopathological study of 30 cases of Acanthamoeba keratitis are construed as indicating a four stage pathogenetic sequence: (1) initial infection, involving breaching of the surface epithelium; (2) keratocyte depletion by the invading trophozoites; (3) inflammatory response mediated by neutrophil polymorphonuclear leucocytes; (4) stromal necrosis attributable to leucocytic ac...

Considerable information has been accumulated concerning the herpes virus and its relationship to man, its natural host (Table VI). It is evident that to control the diseases produced, by the virus it is essential that some means be found not only to control the acute manifestations but also to eliminate the harbored virus from the readily available supply in the numerous ubiquitous carriers. A...

AIMS This study was designed to assess the relative efficacy of topical ganciclovir 0.15% gel and acyclovir 3% ointment in the treatment of herpes simplex dendritic keratitis. METHODS Both treatment modalities were administered on a five times daily basis to patients suffering from herpes simplex keratitis. Patients were assigned randomly to one of the two treatment groups for the purpose of ...

Topical therapy with trypsin, chymotrypsin, and monoxychloroserene, and corneal scrub with iodine, ether, and silver nitrate did not demonstrably reduce the incidence of a positive virus culture from rabbit corneas infected with herpes simplex. It is suggested that the virucidal properties of such substances as measured by their effect on cell-free virus suspensions is not pertinent to the abol...

Acanthamoeba are opportunistic protozoan parasites that can cause painful, visionthreatening keratitis. However the pathogenesis and pathophysiology of Acanthamoeba keratitis remain incompletely understood. Most cases of Acanthamoeba keratitis develop as a result of poor hygiene in contact lens care but it is unclear how amoebae transmigrate from the environment into the cornea leading to infla...
