A 53-year-old man with treated, biopsy-proven Whipple's disease is described during the exacerbation of the disease, and several new findings not previously reported in association with this disease are presented. The unique combination of ocular signs included uveitis, glaucoma, epiphora, superficial punctate keratitis, and an unusual fibrovascular pannus involving the anterior chamber angles and corneal periphery of both eyes. These ocular abnormalities emphasize the need for thorough ophthalmologic evaluation of all patients with Whipple's disease.

The nonophthalmic physician confronted by a patient with a red eye should be able to distinguish common microbial or allergic conjunctivitis from potentially blinding disorders, such as acute angle closure glaucoma, uveitis, or herpes simplex keratitis, and should remain alert for an associated systemic disease, such as rheumatoid arthritis, polycythemia, or carotid cavernous fistula. The physician should approach the red eye systematically: take a careful history, including type of pain; measure visual acuity; observe the pattern of redness, the type of discharge, the shape of the pupil, and the opacities of the media; and measure the intraocular pressure.

We initiated a pathologic investigation of ocular disease in wallabies. Of 21 animals examined, the eyes were investigated histologically in 11; in four of these animals the brains were also available for section and the sera were investigated in three. In ten animals only sera were received. Histologic studies showed bilateral or unilateral cataract in five animals. Eight animals, with or without cataracts, showed various degrees of keratitis, uveitis, choroidoretinitis, or endophthalmitis. In three animals Toxoplasma cysts were found within the retina or brain, or both. Of the 13 cases examined serologically 11 were positive for toxoplasmosis; three reached high titers.

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.

The distribution of living and dead microfilariae in 160 cases of ocular onchocerciasis has been studied. A model for coding the densities in 9 different areas of the cornea has been used. The average numbers of microfilariae and onchocercal punctate opacities per square millimetre were assessed. The highest densities were found in the superficial one-third of the corneal stroma at the periphery of the nasal and temporal parts of the cornea. Sclerosing keratitis was also recorded, and the average age of the patients in this group was significantly higher than in the group with non-sclerosing onchocercal involvement. Corneal thickness measurement showed that the presence of microfilariae or onchocercal punctate opacities or a faint uveitis did not influence the values. In sclerosed areas the corneal thickness varied greatly and was dependent on the degree of the vascularisation. The routes of entry of microfilariae into the eye are discussed on the basis of the distribution patterns of microfilariae and onchocercal opacities.

A case history of a 15-year-old schoolgirl with fluctuating bilateral uveitis, bilateral stromal keratitis with vascularisation, and bilateral deafness associated with tinnitus and balance disturbance is described. Three years from the onset of her clinical signs she died of a sudden cardiac arrest caused by endocarditis associated with valvular and arterial lesions. Chlamydia psittaci was isolated from her conjunctiva. In her blood type-specific antichlamydial antibody at a level of 1/64 against her own isolate was detected. The clinical findings in this patient were suggestive of a Cogan's syndrome. It is highly probable that the chlamydia isolated from the eyes was responsible for her various lesions.

This critical review is based upon controlled experimental and clinical data. Dendritic keratitis initially should be treated by debridement of the diseased epithelium followed by antiviral medication. The advantages and disadvantages of different debridement techniques and different synthetic antivirals are discussed. Rational treatment of other forms of herpetic eye disease with antivirals, steroids, therapeutic soft lenses, collagenase inhibitors etc. necessitates first of all an exact diagnosis (disciform edema, interstitial herpetic keratitis, herpetic (kerato-)uveitis, metaherpetic erosion, metaherpetic ulcer). Therapeutic or prophylactic measures which as yet have found no valid experimental or clinical basis are discussed as well as further developments. Special interest is laid upon the application of human interferon.

Patients with active herpetic epithelial keratitis who had toxic reactions or were resistant to idoxuridine received vidarabine. Only one of 35 cases of herpetic epithelial keratitis without stromal disease failed to heal. Of 21 patients with active epithelial keratitis complicating stromal keratitis or uveitis. 11 had complete reepithelialization by day 14. Two patients were removed from the trial as treatment failures. The remaining cases healed in 21 to 48 days. In most instances the stromal keratitis was inactivated when the epithelial ulcer healed. In our patients treated with vidarabine, healing of herpes simplex epithelial ulcers was biphasic: Stage 1, progression from an active to an inactive viral ulcer, and Stage 2, complete reepithelialization.

Interaction of leucocytes with human corneal endothelial cells (HCECs) can be observed in several clinicopathological conditions, such as uveitis, keratitis, and corneal graft rejection. Since leucocyte-endothelial cell interactions involve various adhesion receptors we have analysed the expression and distribution pattern of the neural cell adhesion molecule (NCAM), the intercellular adhesion molecule-1 (ICAM-1), the vascular cell adhesion molecule-1 (VCAM-1), the endothelial leucocyte adhesion molecule-1 (ELAM-1), and the cluster of differentiation antigen-44 (CD44) on flat preparations of normal and organ-cultured HCECs. NCAM and ICAM were constitutively expressed on HCECs whereas VCAM-1, ELAM-1, and CD44 were absent from normal HCECs. However flat mounts of HCECs from organ-culture preserved corneas showed a mosaic-like distribution pattern of VCAM-1 and ELAM-1 positive cells and garland-like clusters of CD44 positive cells. We suggest that modulation of ELAM-1, VCAM-1, and CD44 expression on HCECs may contribute to the regulation of leucocytes-HCECs interaction in the case of anterior segment inflammation.

Herpes simplex disciform keratitis is a difficult condition. The general feeling is that it is an immune disease, mediated by the virus, possibly located in the endothelial cells. It is frequently combined with inflammation in the trabecular meshwork and with uveitis. There is some controversy in relation to treatment and it has been suggested that anti-virals will control herpetic disciform keratitis, particularly if the patient has never had steroids previously. The authors of this paper have, in the past, published data which showed that Acyclovir, with corticosteroid, was necessary in the management of disciform keratitis. The data suggested that Acyclovir on its own was not effective. It remained to be answered whether Acyclovir on its own would be effective in patients who never had steroids for any reason previously. This paper demonstrates clearly that it is necessary, irrespective of whether patients have had steroids in the past or not, to combine corticosteroids with Acyclovir in the management of herpetic disciform keratitis. Acyclovir, on its own, is shown to be ineffective. It has also been suggested that Acyclovir is non-toxic. In a general way this is true, but the authors suggest that Acyclovir ointment does produce a punctate keratitis in patients with tear film disease, and that oral Acyclovir is preferable in such patients.
