Propionibacterium acnes endophthalmitis seven months after extracapsular cataract extraction and intraocular lens implantation.

We present a case of endophthalmitis caused by Propionibacterium acnes seven months following extracapsular cataract extraction and intraocular lens implantation. The markedly delayed clinical course of endophthalmitis associated with this organism appears to be highly stereotypical. Recognition and treatment of this complication of cataract surgery allows an excellent chance at cure.

Spectrum of Sjögren syndrome in children.

Sjögren syndrome, consisting of keratoconjunctivitis sicca and xerostomia with or without another autoimmune disease, is uncommon in children. We describe our retrospective experience with eight pediatric patients with SS. All had recurrent parotid enlargement and abnormal salivary gland biopsies, six had keratoconjunctivitis sicca, and five had other autoimmune manifestations, although only two of these had other clearly defined autoimmune disorders (mixed connective tissue disease and hypergammaglobulinemic purpura). Our patients had a higher incidence of primary SS, parotid enlargement, and hematologic abnormalities than did children previously reported with SS. Children with SS demonstrate a clinical heterogeneity comparable to that seen in adults.

Possible foreign body granuloma of the retina associated with intravenous cocaine addiction.

A 27-year-old man who was a heroin addict had light flashes in front of the right eye and a hemicentral scotoma immediately after intravenous cocaine. The initial ophthalmoscopic appearance was of a white foreign body lying over the papillomacular bundle of the retina in the right eye. This ophthalmoscopic finding was consistent with intraocular talc, cornstarch, or lactose, common diluting agents that are present in intravenous injections of heroin, cocaine, or methylphenidate hydrochloride, and are known to cause systemic embolic phenomena in chronic drug abusers. This glistening crystal on the surface of the retina changed and evolved into a noninfectious but inflammatory organization of retinal granuloma, in which the foreign body crystal could still be visualized at the apex of the lesion. The anterior and posterior segments of the eye remained free of inflammatory signs throughout the course of the organization of the retinal granuloma.

Listeria monocytogenes endophthalmitis.

A 62-year-old white man developed an acute anterior chamber inflammation in his left eye. Listeria monocytogenes was cultured from the vitreous aspirate. There was no evidence for ocular trauma or distant site of infection from which hematogenous spread of the organism occurred. No underlying state of immunocompromise was demonstrated. The endophthalmitis responded well to therapy.

Acute hemorrhagic conjunctivitis in Tunisia. Report of viral isolations.

Acute hemorrhagic conjunctivitis (AHC), a new disease entity first reported in 1969, has since become pandemic throughout the world. In Tunisia during an epidemic in 1972 to 1973 we studied 25 cases of AHC, which were characterized by explosive onset of lid edema, chemosis, conjunctival hemorrhages, follicular hypertrophy, and epithelial keratitis. Clinical signs peaked in 48 hours and cleared without sequelae in five to seven days. Paired acute- and convalescent-phase sera from six of the patients showed a rising titer of neutralizing antibody to the prototype strain of AHC virus (J6 70/71), which was isolated in Japan. Two viral isolates from Tunisian patients were also antigenically related to the Japanese strain, indicating that a single etiologic agent (a new member of the picornavirus group) is probably responsible for the current pandemic of AHC.

Herpes simplex keratitis in a developing country. Natural history and treatment of epithelial ulcers in Tunisia.

Herpes simplex keratitis was found to be a common ophthalmic problem in Tunisia. Dendritic and geographic ulcers were complicated by deep stromal keratitis in 31% of patients, two thirds of whom were known to have been treated previously with corticosteroids. Herpes simplex virus was isolated from 41% of patients from whom corneal material was cultured. To develop an effective program for management of epithelial herpes in developing countries, treatment with idoxuridine was compared with debridement and patching. Average healing time for 31 ulcers treated with idoxuridine was 13 days, with three treatment failures; average healing time for 20 ulcers treated with debridement and patching was five days, with one failure. Debridement and patching of herpetic ulcers was an efficient way to treat herpes simplex keratitis within the context of overall medical care in Tunisia.

The Francis I. Proctor Foundation: the first fifty years.

September 15, 1997 marked the golden anniversary of the Francis I. Proctor Foundation, which was established in affiliation with the University of California in San Francisco. Over 50 years, 182 fellows from 27 countries have been trained in programs focusing on the study of infectious and inflammatory eye disease, and the prevention of blindness worldwide. Many of the people and events that have contributed to the success of the Proctor Foundation are presented in this brief essay.
