2,277 specimens from 901 eyes were cultured for herpes simplex virus (HSV). 161 of 391 herpes-diseased eyes yielded HSV. The clinico-virological correlation led to a simple diagnostic and therapeutic scheme which is applicable by the ophthalmologist in his office without virological confirmation: 1. Superficial viral herpes (dendritic keratitis and allied disorders), HSV-isolating rate 96%. 2. Stromal herpes (disciform edema, different types of interstitial herpetic keratitis), only sporadical findings of HSV in the lacrimal fluid. The rate of virus-recovery increases, however, when an interstitial herpetic keratitis ulcerates. 3. Metaherpetic corneal disease = chronic or chronic recurrent superficial postherpetic disease without any detectable HSV-activity (main types: metaherpetic erosion, metaherpetic ulcer, metaherpetic bullous keratopathy). One of four superficial herpetic corneal diseases proved to be nonviral, i.e. metaherpetic in our series. Metaherpetic diseases may be widely considered as a therapeutic entity. The differential diagnosis with the slitlamp only and the proposed therapy (highly hydrophilic soft lenses plus adequate additional eye drops) are discussed in detail. Being aware of the diagnostic criteria and taking advantage of a combined soft lens therapy the treatment of metaherpetic corneal disease is easier and more successful than commonly accepted.

The most common causes of acquired corneal scarring before age 6 are herpes simplex keratitis, penetrating injuries, and congenital dystrophies. We performed 18 keratoplasties in 16 eyes of 15 patients under the age of 12 years, achieving clear grafts in 14 eyes (87%). We also performed 11 grafts in nine eyes of eight patients with congenital, central corneal opacities, achieving only one clear graft and four instances of phthisis bulbi or enucleation for buphthalmos. We do not recommend penetrating keratoplasty in patients with unilateral, congenital corneal opacities. However, those with bilateral cloudy corneas should have an attempt at kertoplasty as early in life as possible. The social and psychologic condition of the family often makes the difference between success and failure.

Fifty strains of herpes simplex virus, isolated from patients with herpetic keratitis, were examined in vitro for susceptibility to polyinosinic acid-polycytidylic acid [poly(I:C)] in the presence of a constant concentration of diethylaminoethyl-dextran. The minimal inhibitory concentration of poly(I:C) for 44 of these strains ranged from 0.0001 to 0.1 mug/ml; for the remaining six strains, the minimal inhibitory concentration stood at 1 to 2 mug/ml. Fifteen isolates from primary infections were more susceptible to poly(I:C) than 35 isolates from recurrent infections. Isolates acquired at different points of a given clinical episode showed similar susceptibilities to poly(I:C). In two patients, isolates from consecutive recurrences of infection exhibited reduced susceptibilities. The implications of the above observations for the therapeutic use of poly(I:C) are discussed.

Sheep antihuman IgG-antiferritin hybrid antibodies were used for the ultrastructural localization of herpes simplex virus (HSV) antigens in rabbit corneas from animals with herpetic keratitis. In animals with epithelial keratitis in which active viral replication is occurring (6 days after infection), viral antigen was found within nuclei, on nuclear membranes, and on cell surface membranes of epithelial cells. In animals with early necrotizing keratitis in which active viral replication cannot be demonstrated (14 to 21 days after infection), viral antigen was found in association with the cell surface of stromal keratocytes. Since lymphocytic cells in intimate contact with degenerating keratocytes have previously been identified in the cornea, these observations provide a basis for the view that cell-mediated immunopathogenesis is involved in the etiology of herpetic stromal keratitis.

Treatment of human skin and corneal fibroblasts with prednisolone-21-phosphate did not increase the capacity of these cells to replicate type I herpes simplex virus (HSV). The steroid however was found to (1) inhibit human lymphocytes from mediating antibody-dependent cell-mediated cytotoxicity (ADCC) against HSV-infected fibroblasts and (2) suppress the replication of virus in PHA-stimulated human lymphocytes. The data suggest that the exacerbation observed when patients with dendritic keratitis are inadvertently treated with prednisolone may be due to the steroid suppressing ADCC and not by promoting the growth of virus in the corneal cells.

In a masked controlled study we compared 3% acycloguanosine, 0.5% idoxuridine, and 3% vidarabine ointments in therapy of experimental herpes simplex virus keratitis in rabbits. The results of the acycloguanosine group were significantly better than the control groups and both other treatment groups, while producing none of the toxic side effects of increasing iritis, conjunctivitis or stromal keratitis, with continued drug application.

The authors report two cases of severe herpetic keratitis and briefly discuss the possible mechanism of acquired idoxuridine resistance of herpes simplex virus. They believe that acquired resistance to IDU may be due to the treatment itself because of activity site of the inhibitor, i.e. the viral DNA.

Two patients had herpes simplex infection of the fingertips (herpetic whitlow) associated with herpetic keratitis. Both patients were health-care professionals who probably acquired their disease from patients. Herpetic whitlow can be distinguished from a paronychia by the lack of a tense pulp space, formation of vesicles, and serous (rather than purulent) drainage. The fingertip inflammation resolves spontaneously, leaving normal healthy skin, in about two weeks.

Previous results obtained in experimental and clinical trials have demonstrated that topical combined thrapy with human interferon (HI) and human colostral secretory immunoglobulin A (S-IgA) is effective against herpetic corneal infection. This therapy prevented encephalitis in rabbits but could not completely prevent recurrences either in rabbits or in patients. A number of in vitro studies were designed to elucidate the role of these factors in herpes simplex virus replication in the nervous system, with the following results: (1) HSV latency in trigeminal ganglia (TG) explanted from rabbits with experimental herpetic keratitis, topically treated with HI or HI/S-IgA: HSV was recovered in 30% TG after 15-19 days co-cultivation on RK-13 cells. (2) HSV replication in nervous ganglia and nerve of newborn rabbits in organ culture; influence of HI or HI plus IgG: a restrictive HSV productive infection was demonstrated in this system, although yields were always higher in nerve cultures. We were unable to demonstrate a direct effect of HI on HSV-1 replication. When explants were treated with HI and IgG before and after infection for 48 hours a delay in the expression of HSV-1 was detected by co-cultivation. (3) Replication of HSV-1 and HSV-2 in a C1300 murine neuroblastoma clone (NB41A3): both HSV types replicated with titres of 10(3.4) for HSV-1 AND 10(4.8) for HSV-2 at 48 hours p.i.; CPE was more marked for HSV-2 at 24 hours. HSV-specific antigens were demonstrated by the immunoperoxidase technique.

Since herpes simplex virus (HSV) can cause persistent infection of autonomic ganglia of both humans and experimentally infected animals, we followed the pattern of eye disease and viral growth after HSV inoculation of one superior cervical ganglion in rabbits. Of 27 inoculated animals, eye disease or detectable virus developed in 18. Anterior uveitis was the most common clinical manifestation (94%), but conjunctivitis and dendritic keratitis were also frequent (60%). All 12 uveal-retinal specimens tested and five of seven ipsilateral superior cervical ganglia had detectable virus. If recurrent herpetic iritis in humans is associated with persistent infection of the superior cervical ganglion, autonomic mediators might trigger episodes of virus shedding. In patients with herpetic iritis, then, the use of epinephrine and other adrenergic agonists or antagonists should be avoided.
