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.

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.

Active immunization against Pseudomonas aeruginosa keratitis and systemic disease in mice was studied. In the first series of experiments, monovalent vaccine, administered orally or intraperitoneally, protected against subsequent corneal and intraperitoneal challenge with the homologous strain of P. aeruginosa; however, oral administration of vaccine elicited less protection than intraperitoneal administration. After both routes, protection was observed at 11 and 32 days post-vaccination, but it was greater at 11 days. In the second series of experiments, multivalent vaccine administered intraperitoneally protected against corneal challenge with 56 to 78 percent of 18 strains.

From 1969-1974 1000 unselected enucleated globes have been examined histopathologically. 277 derive from the University Eye Hospital in Hamburg, 723 from various Eye Hospitals in northern and southern Germany. They originate from 589 men and 408 women, three times the sex was unknown. 86 globes had to be removed from children less than 15 years old. 6 groups of etiologies have been distinguished: trauma (308), histologically confirmed neoplastic disease (281), ocular manifestations of systemic diseases (diabetes mellitus, occlusions of central retinal vessels presumably following generalized vascular disease etc.: 128), "operative ocular disease" (164), primary inflammatory disease (71), miscellaneous (malformations, high myopia, pseudo-glioma and pseudo-melanoma: 48). The etiology "operative ocular disease" consists of 67 primary glaucomas (57 adults, 10 buphthalmus), 41 idiopathic cataracts (7 of these congenital) and 3 primary corneal dystrophies, as well as 53 cases of primary retinal detachment. Among the 281 neoplastic diseases, there are 238 primary intraocular malignant melanomas of the uvea, 18 retinoblastomas, 4 primary reticulumcellsarcomas of the retina, 2 choroidal nevi, 10 intraocular metastases and 9 orbital tumors. 16 enucleations among the 1000 enucleations have been performed for pseudo-gliomas (5 x Coats disease, 5 x persistent primary hyperplastic vitreous, 2 x retrolental fibroplasia, others 4 x). The manifestations of systemic disease are consisting of 68 central retinal vein-occlusions, 30 complications of diabetes mellitus and 10 central retinal artery occlusions as well as 20 other generalized diseases. A primary inflammatory disease led to enucleation 50 times due to an intraocular process, 5 times due to scleritis and 18 times as a consequence of keratitis (including 13 times herpes simplex). As the final clinical cause for enucleation the following categories have been elaborated: secondary glaucomas (416), clinical diagnosis of "tumor" (275), atrophy and phthisis bulbi (118), inflammation (112), acute trauma to 4 weeks after the accident (72), others (7). In conclusion the central role of rubeosis iridis leading to secondary angle closure glaucoma is emphasized. This process presents a challenge to ophthalmologic research. Finally the significance of early surgery for primary angle closure glaucomas and for complete restoration of the anterior chamber after trauma and any intraocular procedure is stressed.

Many studies have described the presence of circulating antibodies against corneal components in patients with corneal disease or uveitis, and in patients with skin or systemic disease with or without ocular involvement. The role of such antibodies in the underlying immunopathological process remains obscure. Here we describe the induction of autoantibodies against the rat cornea. Our attempts to induce corneal autoantibodies by various forms of keratitis and corneal trauma failed. However, circulating corneal autoantibodies could be detected by Western blotting after immunization of BN rats and Lewis rats with bovine corneal protein 54 (BCP 54). Rats immunized with rat corneal extracts (RaCE) or human serum albumin (HSA) as (auto) antigen did not develop corneal autoantibodies. During the study period (greater than 4 months), it was observed that the presence of circulating corneal autoantibodies did not elicit corneal inflammation. Severe keratitis did develop when BCP 54-immunized rats were challenged intracorneally with BCP 54, but the clinical signs were not significantly different from HSA-immunized rats after an intracorneal HSA challenge. Injection of corneal autoantibodies into the corneal stroma did not provoke keratitis. To the best of our knowledge this is the first study demonstrating corneal autoantibodies in rats without actual manipulation of the eye. This model may provide further insights in the role and significance of corneal autoantibodies in disease.

Ninety-eight patients were studied. Ninety were consecutive patients who were isolation-positive for adenovirus, and 8, who were associated with a hospital outbreak of adenovirus serotype 8 infection, developed characteristic features of infection but were isolation-negative. The ratio of males to females was 2 to 1, and most patients were aged 20 to 39. Adenovirus serotypes 3, 7, and 8 were isolated from 86% of patients, and serotypes 2, 4, 5, 11, 15, and 15/29 from the remaining 14%. Adenovirus serotype 7 was more commonly isolated from patients under the age of 19 and was Not isolated during winter. Sources of infection could be identified in 36% of patients and included contact with upper respiratory tract of ocular infections, a hospital outbreak, and a recent visit to a swimming pool. Associated systemic disease was detected in 47% of patients, most of whom had upper respiratory tract infection. The most severe and prolonged conjunctivitis was caused by serotypes 5 and 8. Most patients developed epithelial punctate keratitis. Subepithelial punctate keratitis, which was once-considered to be a characteristic feature of adenovirus serotype 8, developed in cases of serotype 3, 4, 5, 7, and 8 infection.

The lacrimal gland has been investigated by a number of authors with specific interest in the relationship between keratitis sicca and systemic disease. Neoplastic involvement of the lacrimal gland and lacrimal sac have drawn the attention of others. Imaging of the lacrimal drainage system by ultrasonography, computerized axial tomography, and magnetic resonance imaging has been reviewed. Finally, surgical approaches to dacryocystorhinostomy and attendant complications have been studied.

The term 'vasculitis' includes a wide range of disorders characterised by inflammation of the wall of blood vessels, sometimes with necrosis, leading to ischaemia of the affected organ. The exact pathogenesis of most of these vasculitides is not fully understood and although the presence of circulating auto-antibodies seems to be a common feature among them, each vasculitis has its unique pathogenesis and a predilection for vessels of a defined size. Systemic vasculitis may be associated with ocular complications which include scleritis, keratitis, uveitis and optic neuropathy. These can precede the symptoms/signs of the systemic disease and therefore their recognition may lead to detection of the underlying disorder. The eye may also be affected by the treatment required to control the systemic disease.

Animal models of aspergillosis have been used extensively to study various aspects of pathogenesis, innate and acquired host-response, disease transmission and therapy. Several different animal models of aspergillosis have been developed. Because aspergillosis is an important pulmonary disease in birds, avian models have been used successfully to study preventative vaccines. Studies done to emulate human disease have relied on models using common laboratory animal species. Guinea pig models have primarily been used in therapy studies of invasive pulmonary aspergillosis (IPA). Rabbits have been used to study IPA and systemic disease, as well as fungal keratitis. Rodent, particularly mouse, models of aspergillosis predominate as the choice for most investigators. The availability of genetically defined strains of mice, immunological reagents, cost and ease of handling are factors. Both normal and immunosuppressed animals are used routinely. These models have been used to determine efficacy of experimental therapeutics, comparative virulence of different isolates of Aspergillus, genes involved in virulence, and susceptibility to infection with Aspergillus. Mice with genetic immunological deficiency and cytokine gene-specific knockout mice facilitate studies of the roles cells, and cytokines and chemokines, play in host-resistance to Aspergillus. Overall, these models have been critical to the advancement of therapy, and our current understanding of pathogenesis and host-resistance.

Atopic keratoconjunctivitis (AKC) is presently considered as an individual nosological entity of ocular allergosis, which is associated with the systemic disease - atopic dermatitis. The clinical features of corneal lesions were studied in 40 patients with AKC. Those associated with the systemic pattern of an atopic process as a severe form of ocular allergosis were revealed. A classification of the clinical forms of corneal lesions in AKC as limbitis, epithelial microerosions, epithelial keratopathy, superficial keratitis in mild forms of the disease, is presented. The severe forms of AKC were characterized by corneal manifestations: extensive keratopathy, stromal keratitis with neovascularization without ulceration, corneal infiltrates and ulcers of bacterial and herpetic etiology.
