In an epidemic of viral keratoconjunctivitis in Bulgaria in 1972, caused by adenovirus 9, we applied ABOB in 1 percent solution topically in 120 of all 151 observed patients. When the treatment could be begun in first 3-5 days of the disease, a very favourable curing effect was noted. In most of the patients occurred a significant subjective improvement. The effect was most pronounced upon the course of ther keratitis stage. When ABOB was applied early, the observed keratitis was lighter, with slight visual impairment (with a duration of more than one month in 14.4 percent of the patients, as opposed to 57.3 percent in a placebo group), with quicker epithelialization of corneal erosions and, as a result, with fewer residual corneal opacities.

Combinations of neomycin sulfate and polymyxin B sulfate are commonly used in ophthalmic ointments for the treatment or the prevention of bacterial keratoconjunctivitis. In this study we evaluated the effectiveness of various ointments containing these two antibiotics, alone and in combination, in preventing Staphylococcus aureus keratitis in rabbits. Rabbit eyes were infected by intracorneal inoculation, treated topically with ointment and graded by gross observation 24 hours after inoculation. Treatment with ointments containing neomycin alone offered significant protection against these corneal infections. The polymyxin B ointments, as well as the vehicle controls, were ineffective in preventing S aureus infections in the rabbit eyes. However, by far, the most effective ointment formulations tested were the combination ointments and specifically those containing 1.75-3.50 mg neomycin and 3,000-6,000 units polymycin B per gram of ointment.

Of 120 individuals suffering from follicular conjunctivitis, with or without keratitis, 56 had epidemic keratoconjunctivitis caused by adenovirus type 8. The remaining 64 patients had keratoconjunctivitis produced by several different viruses, including herpes simplex, adenoviruses types 3, 7, 8, 16, 21, and 29, and others. Positive viral cultures were difficult to obtain after the first week of illness in most viral infections. Serologic tests were far more successful in indetifying causative agents. Hemagglutination-inhibition tests in adenovirus infections proved to be fast, accurate, and more sensitive than other serologic tests. Among the epidemic and nonepidemic adenovirus groups, the degree of corneal involvement in the infections appeared to be correlated with the level antibody against the infectious agent. Patients with low antibody titers had more severe keratitis than those with high titers. This correlation was true for both the epidemic and non epidemic patients.

Since July 1973 cases of keratoconjunctivitis resembling epidemic keratoconjunctivitis were observed in the External Eye Disease Clinic at Moorfields Eye Hospital; City Road, London. Adenovirus type 19 was isolated in human embryonic kidney cells from 21 patients. The majority were males between 20 and 40 years old. A small hospital outbreak involving six patients occurred. Clinical features of the disease, consisting of moderate to severe follicular conjunctivitis, major subepithelial punctate keratitis, sometimes with pseudomembrane and scarring, were closely similar to those of epidemic keratoconjunctivitis caused by adenovirus type 8. This similarity, as well as the ability of the agent to cause hospital outbreaks, indicates that adenovirus type 19 is a cause of epidemic keratoconjunctivitis. A case of bilateral chronic papillary conjunctivitis that persisted for 16 months following an acute onset was described. Adeno 19 was isolated from the eye of the patient after 12 months of recrudescent or recurrent illness. Chronic adenovirus infection lacking the usual clinical picture of an acute follicular reaction has not hitherto been described. Such cases are probably important because of the obvious danger of continuing the carriage and shedding of infective adeno 19 from one outbreak to another, by presenting subsequently in eye clinics, and providing an unrecognised source of infection to initiate further outbreaks of hospital transmission.

A case of keratoconjunctivitis caused by adenovirus type 21 in London has been described. A 59-year-old woman attented hospital in August 1974 complaining of a 3-week history of redness, grittiness, watery discharge, and photophobia in her left eye and a slight upper respiratory infection. Clinical examination showed a moderate follicular conjuctivitis mainly in the lower and upper fornices, which lasted for 6 weeks. In the cornea a moderate amount of epithelial and subepithelial punctate keratitis was observed. The subepithelial opacities were coarse, discrete, and round and lasted for 4 months. The course of follicular conjunctivitis and the subepithelial punctate keratitis in this patient was similar to epidemic keratoconjunctivitis caused by adenovirus 8. A conjunctival swabbing collected from this patient was positive for adenovirus serotype 21.

Nineteen cases of keratoconjunctivitis caused by an adenovirus serologically related to types 10 and 19 are described. Seventeen of the patients presented over a period of 7 weeks and included 4 who were involved in a minor outbreak at a factory. The presentation and clinical features closely resembled those caused by adenoviruses types 8 and 19. Mild to severe follicular conjunctivitis, superficial punctate keratitis, discrete subepithelial opacities, membrane formation, and conjunctival scarring were all observed.

The authors present the results of morphological study of experimentally-induced conjunctivitis and keratitis induced in guinea pigs by salmonellae. It was revealed that injuries of the conjunctiva and cornea in salmonellae infection were different by development and morphological manifestations from keratoconjunctivitis caused by shigellae. This difference was due to specific peculiarities of the pathogenic properties of salmonellae and shigellae clearly expressed on the given experimental model.

A double-masked, coded trial was undertaken to evaluate the effect of the topical administration of 2% cromolyn sodium eye drops on vernal keratoconjunctivitis in 14 children. One eye of each patient was treated for one year with cromoly, the other eye with placebo. Cromolyn reduced the characteristic vernal keratitis, vernal corneal ulcers and plaques, and limbal edema and infiltrates but did not affect the number or size of the giant papillae. The drug's long-term topical use did not have any adverse side effects.

A case of bilateral keratoconjunctivitis caused by self-instillation of a 1% aqueous solution of gentian violet was complicated by a secondary uveitis and gram-negative conjunctivitis. The patient was treated with cycloplegics and specific antibiotics and after resolution of the bacterial infection, a mild topical corticosteroid was used. After six months the patient had completely recovered from the keratitis, but bilateral corneal vascularization, had unilateral posterior synechiae, corneal scarring, and cataract formation were present. Cationic dyes such as gentian violet appear to be toxic to the ocular surfaces and tend to produce severe intraocular inflammation.

During the 18 months January 1975 to June 1976, 25 cases of acute herpetic follicular conjunctivitis and keratoconjunctivitis resembling adenovirus ocular infection presented in the External Eye Disease Clinic, Moorfields Eye Hospital, City Road, London. Herpes simplex virus was isolated in HEp2 cells in 22 patients, and the remaining 3 patients were identified by a minimum 4-fold rise in the level of antiherpes simplex virus antibody in their blood. No adenovirus was isolated from these patients, but complement fixation test for adenovirus was positive in 1 patient with cultural test positive for herpes simplex virus. Most patients were between 20 and 35 years old and the ratio of males to females was 12 to 13. At the initial visit the clinical features of disease were moderate to severe conjunctival papillary and follicular reasons with epithelial and subepithelial punctate keratitis but little systemic disease. In the absence of typical herpetic lesions of face, lids, or cornea the disease resembled adenovirus types 8 or 19 keratoconjunctivitis. Of these 25 patients 5 subsequently developed typical herpetic lesions of lids or cornea. In the remaining 20 cases the correct diagnosis could be made only by cultural or serological tests. Virological diagnosis provides a rational basis for antiherpetic chemotherapy, which appears to shorten the course of infection.
