The clinical spectrum of ocular disease in 37 patients with atopic keratoconjunctivitis (AKC) is described. Patients typically had a severe blepharoconjunctivitis. Associated corneal scarring, suppurative keratitis, or keratoconus were the major causes of visual loss. Serum and tear samples from these patients were analyzed to quantify total and specific IgE antibodies. The results were compared as a case control study with results from samples from 55 patients with other forms of atopic disease and 16 nonatopic volunteers. Although the mean values for total and specific IgEs in the serum of patients with atopic disease were markedly higher than the values from nonatopic controls (P less than 0.00002), a difference between the disease groups could not be demonstrated (P greater than 0.05). There were also differences between both the total IgE (P = 0.0002) and pollen-specific IgE (P = 0.015) in tears from patients with atopic disease and nonatopic controls, but not for house dust mite or cat dander-specific IgEs. These results suggest that clinical differences between groups of patients with chronic allergic external eye disease are not associated with specific patterns of IgE production.

Individuals with atopic dermatitis are particularly susceptible to herpes simplex viral infection and may develop dissemination (eczema herpeticum). Additionally, they may develop severe and bilateral herpetic ocular disease. The keratitis is commonly complicated by stromal scarring and slow epithelial healing despite topical antiviral therapy. We treated three patients who had herpetic keratoconjunctivitis associated with eczema herpeticum. In all three cases the keratitis resolved promptly (48 to 72 hours) without residual scarring after treatment with systemic acyclovir and topical trifluridine. The combined use of systemic acyclovir and topical trifluridine may be of similar value in treating all cases of atopic herpetic keratitis.

Corneal replicas were made from the severely affected eyes of 12 patients presenting with typical signs and symptoms of epidemic keratoconjunctivitis. Adenovirus was isolated from the eyes. Histopathological study of the replicas and cytology of diseased cells removed with the replica showed diffuse mild oedema of the epithelium, with scattered moderately swollen and deformed cells. The clinically observed punctate lesions histologically consisted of markedly swollen cells that had become oval or rounded. Fusion of these cells led to small syncytial formations, and the development of pseudopodia-like processes was occasionally observed. Loss of cell contents resulted in the formation of plicae on the surface of many cells. Two types of inclusion bodies were detected in the epithelial cells. The first type, intranuclear vacuolar inclusions, contained homogeneous material. The second type of inclusions were round, dense bodies, that developed in the homogeneous material of intranuclear vacuolar inclusions. The dense bodies contained the replicating and maturing virus particles. After cell degeneration the dense bodies become extracellular. Making a corneal replica had a beneficial effect on the clinical course of adenovirus keratitis.

The overriding consideration in choosing between soft contact lenses (SCLs) and rigid gas-permeable (RGP) lenses is the severity of the changes each induces in the corneal epithelium, endothelium, and conjunctival structures. Lens-related epithelial changes are largely the consequence of relative oxygen deprivation and consequent corneal edema. Factors such as lower oxygen transmissibility, minimal tear exchange capacity, and large diameters may explain why SCL wearers show a higher rate of corneal infiltrates, sterile ulcers, and irregular staining patterns than users of RGP lenses. The greater association of hydrogels with infectious keratitis may reflect their tendency to accumulate proteinaceous deposits, harbor bacteria in the polymer matrix, and resist easy disinfection. SCL wear has been linked to endothelial polymegethism, a largely irreversible condition that may cause more rapid corneal swelling and slower deswelling after periods of hypoxic stress. Among the conjunctival problems more often seen in SCL wearers are superficial neovascularization, contact lens-related superior limbic keratoconjunctivitis, and giant papillary conjunctivitis. Mechanical irritation from large-diameter lenses, a tendency to build up mucoproteinaceous deposits, corneal draping, and hypersensitivity to preservatives in SCL care products may play a role in these problems.

A prospective double blind study was carried out to evaluate the role of soluble antigen fluorescent antibody (SAFA) test to detect ocular Tuberculosis. The study material comprised 39 patients with suspected ocular tuberculosis suffering from interstitial keratitis, sclero keratitis, granulomatous uveitis, phlyctenular keratoconjunctivitis, Eales disease and central serous retinopathy. The cases of proven ocular tuberculosis showed up as 70 percent strong reactors and 30 percent weak reactors to SAFA while none had a negative response to SAFA. Of these cases skin hypersensitivity reaction was positive only in 40 percent of the cases. The control group revealed a strong SAFA reaction in only 4 percent of cases with a weak reaction in 44 percent of cases. It thus appears that SAFA test can provide a useful addition to the routine tests in diagnosing tuberculosis.

A study of the therapeutic effect in 159 patients with epidemic keratoconjunctivitis treated by antiviral preparations: alpha-interferon, prodigiosane, 0.25% phlorenale and 0.05% riodoxole ointments has a sufficiently high effect of the mentioned preparations; the duration of the disease is shorter in these patients as compared with patients treated by common antibiotic preparations. As compared with other medicinal preparations, the therapeutic effect of alpha-interferon and phlorenale was evident not only in the shortening of terms of treatment, but also in prevention of keratitis in such patients. The therapeutic effect was higher when the preparations were prescribed at early terms (1-4 days) of the disease.

Acquired immune deficiency syndrome (AIDS) is associated with a wide spectrum of systemic and ocular infectious diseases. Little information is known about herpes simplex virus type 1 (HSV-1) keratoconjunctivitis in association with AIDS. The authors present six cases of recurrent HSV keratitis occurring in AIDS patients. Features of the herpetic keratitis in these patients included unilateral dendritic or geographic epithelial keratopathy; predilection for peripheral versus central corneal involvement; one to three recurrences per patient over a mean observation period of 17 months, with a median dendrite-free interval of 7 months; and a moderately prolonged clinical course with a median healing time of 3 weeks using topical antiviral therapy. Only one of six cases had stromal infiltrative involvement. These cases raise the question of whether the immunologic abnormalities associated with AIDS may affect the clinical characteristics and course of HSV keratitis.

We report two cases of a previously unrecognized clinical entity: concurrent adenoviral and herpetic ocular infection. The first case was recognized clinically by the presence of herpetic keratitis and findings attributable to epidemic keratoconjunctivitis (EKC) including lid swelling, pseudomembranous and follicular conjunctivitis, subconjunctival hemorrhages, preauricular lymphadenopathy, and corneal infiltrates. Only Herpes simplex virus was recovered by culture. In the second case of apparent EKC (again initially only Herpes simplex was isolated) after maintaining virus cultures long enough to isolate adenovirus, the diagnosis of concurrent infection was established when the second virus was isolated.

The effects of a modified-live infectious bovine rhinotracheitis virus vaccine (administered ocularly or intranasally) on experimentally induced infectious bovine keratoconjunctivitis were evaluated. The modified-live infectious bovine rhinotracheitis virus vaccine was administered to 13 male Holstein calves (intranasally in 4 and ocularly in 9; day 0). Five calves were not vaccinated and served as controls. Calves were examined daily and, starting on day 4, Moraxella bovis was administered ocularly to all 18 calves once daily for 4 days. The eyes of all calves were assigned a clinical score, and the ocular secretions were evaluated for presence of infectious bovine rhinotracheitis virus and M bovis daily until day 19. The severity of the ocular lesions was estimated by scoring the lesions clinically and by determining the protein concentration, myeloperoxidase activity, and WBC count in the tears. By day 5, conjunctivitis, chemosis, and epiphora were observed in all of the calves vaccinated ocularly. The calves vaccinated intranasally developed conjunctival plaques, but did not develop chemosis or photophobia. All of the calves developed keratitis after inoculation with M bovis. The median lesion scores were greater in both groups of vaccinated calves than in the controls. Corneal perforations developed exclusively in the vaccinated calves. The frequency of M bovis isolation from ocular secretions was significantly (P less than 0.05) greater in the vaccinated calves than in the controls. The tears from the intranasally vaccinated calves contained the highest myeloperoxidase activity and WBC count. The mean protein concentration in the tears of vaccinated calves was not significantly different from that in tears of controls.(ABSTRACT TRUNCATED AT 250 WORDS)

An in vitro analysis of glycoprotein produced by nine human ocular isolates of HSV-1 is reported. The source of the isolates was; three patients with recurrent dendritic keratitis, three with chronic stromal disease and three with primary keratoconjunctivitis. Virus strains were labelled with the radioactive precursors (35S) methionine and (14C) glucosamine. Radiolabelled viral glycoproteins were subsequently analysed by sodium dodecyl sulphate polyacrylamide gel electrophoresis (SDS-PAGE), followed by autoradiography. Viral glycoproteins were further characterised by immuno-precipitation with polyclonal and monoclonal antibodies to HSV. The stromal isolates excrete larger amounts of 'soluble' precursor glycoprotein D than those in the other two disease categories. It is possible that the immune response to glycoprotein D is in part responsible for the severity of stromal disease.
