Chronic lesions of the beak, footweb, and eye of geese photosensitized by the comsumption of Ammi majus (L.) are described, 7 weeks after the acute symptoms commenced. Sixty-four (48%) of the 133 birds in the flock showed various degrees of abnormality. All affected birds had stunting of the upper beak and cicatrization and thickening of the footweb. Eighty-nine percent of the affected birds showed ocular involvement, comprising chemosis, blepharoconjunctivitis, keratitis, symblepharon, ankyloblepharon, cicatricial ectropium, and mydriasis.

Previously unreported adverse drug reactions can be difficult to detect and it may be even more difficult to establish a cause and effect relationship, particularly if the adverse reactions mimic naturally occurring disease. In a previous paper we reported 29 patients with granulomatous anterior uveitis, blepharoconjunctivitis, periorbital dermatitis, marginal keratitis and elevation in intraocular pressure (IOP), suspected to be caused by metipranolol (Glauline). With the approval of the District Ethics Committee 7 of those patients were rechallenged with metipranolol 0.3% compared to timolol maleate 0.5% in a double blind trial. The 7 metipranolol treated eyes developed an adverse reaction within 14 days. Metipranolol (Glauline) has been conclusively proven to cause granulomatous anterior uveitis, blepharoconjunctivitis and elevation in IOP, adverse effects never previously reported with any of the ophthalmic topical beta-blockers. The multidose preparations of metipranolol (Glauline) in all three strengths 0.1%, 0.3% and 0.6% and the single dose minim preparation of metipranolol 0.6% have now been withdrawn from clinical use in the United Kingdom.

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.

Staphylococcus epidermidis accounts for nearly one third of all cases of bacterial keratitis in certain geographic areas. Recently, the sensitivity of this organism has changed dramatically so that nearly half of nosocomially acquired systemic S epidermidis infections are resistant to methicillin sodium, cephalosporins, and aminoglycosides. Methicillin-resistant and gentamicin sulfate-resistant S epidermidis causing infectious blepharoconjunctivitis and endophthalmitis has previously been reported. Two cases of methicillin- and gentamicin-resistant S epidermidis keratitis occurred that were treated successfully with topical vancomycin hydrochloride.

The epidemiological and clinical features of recurrent herpes simplex virus ocular infection (RHSV) were studied. Of 108 patients with primary herpes simplex virus ocular infection (PHSV) who were followed up for two to 15 years 35 (32%) suffered one or more recurrent attacks. The recurrence rate was significantly higher in patients under 20 years of age, but there was no significant difference between recurrence rates in males and females. Of 35 patients with RHSV 17 (49%) had one recurrent attack, 14 (40%) had between two and five, and four (11%) had between six and 15 attacks. The mean time interval between PHSV and the first four RHSV attacks was 10 months, and was shorter in subsequent attacks. The duration and severity of RHSV were reduced in successive recurrences. Patients with more severe conjunctivitis and lid lesions during PHSV ocular infection had a higher incidence of recurrent infection. The severity of the corneal signs in PHSV had no influence on the incidence of recurrent infection. Several clinical forms of RHSV were observed. Conjunctivitis associated with lid lesions was observed in 29 (83%) patients. In six (17%) patients the disease presented as an acute follicular conjunctivitis without characteristic lid or corneal lesions. Dendritic ulcer was found in three (9%) patients, and in one of them it was associated with a disciform keratitis. A chronic blepharoconjunctivitis developed in eight (23%) patients. The epidemiological and clinical features of RHSV were compared with those of PHSV.

The epidemiological and clinical features of primary herpes simplex virus ocular infection in 108 patients were studied. Of these, 69 (64%) were aged 15 or over and only eight (7%) were under the age of 5. Associated upper respiratory tract infection was found in 38 (35%) patients and systemic disorders such as mild malaise, fever, and aching in 34 (31%) patients. Common symptoms were redness, watering, discharge, itching, irritation, and lid swelling, whereas pain, photophobia, lid vesicles and ulcers, and blurred vision were less frequent. The major signs consisted of vesicles and ulcers on the lids, papillary responses which were more severe in the upper lid conjunctiva, follicles which were more common in the lower lid conjunctiva, fine and coarse epithelial punctate keratitis, and subepithelial punctate keratitis. Dendritic ulcers and disciform keratitis were found in 16 (15%) and two (2%) patients respectively. The clinical forms of primary herpes simplex virus ocular infection varied. Moderate or severe disease was observed in 41 (38%) and 16 (15%) patients respectively. In eight (7%) patients the disease presented as an acute follicular conjunctivitis without characteristic lid or corneal lesions. A chronic blepharoconjunctivitis which lasted for months developed in 16 (15%) patients. The epidemiological and clinical features in our patients were compared with features of the disease reported previously.

For treatment of herpetic keratitis, 5-iodo-2'-deoxyuridine (IUdR) has been the only drug available in Japan. However, IUdR is not completely satisfactory, and alternative antivirals are required. The Association for Research in Infectious Diseases of the Eye, Japan, carried out a clinical trial in 92 cases of ulcerative herpetic keratitis using 3 percent acyclovir ophthalmic ointment to determine its efficacy and safety. In 63 eyes, it had an excellent effect and ulcers healed within seven days. In 26 eyes, it had a good effect and ulcers healed within 14 days or became half-size within seven days. Therefore, the response to acyclovir in 96.8 percent of cases was excellent or good. The average healing time in 81 eyes in which ulcers disappeared within 14 days was 5.8 +/- 3.4 days. Including the five eyes in which ulcers took more than 14 days to heal, the average healing time of ulcers was 6.6 +/- 4.8 days. Of the 92 patients treated with acyclovir ointment, one had contact blepharoconjunctivitis and another complained of mild irritation. Mild punctate keratitis, as another side effect of acyclovir ointment, was observed in 22 eyes (23.9 percent) by photo-slit lamp examination, but in these patients it was possible to continue treatment without complaint.

Herpes Zoster Ophthalmicus (HZO) is not an uncommon condition in the elderly and the immunocompromised. The common ocular manifestations include blepharoconjunctivitis, keratitis and uveitis. Dramatic presentations like orbital apex syndrome and superior orbital fissure syndromes occur rarely in patients with herpes zoster meningo-encephalitis. We report a patient with herpes zoster meningo-encephalitis and the superior orbital fissure syndrome (SOFS).

Herpetic stromal keratitis (HSK) and blepharoconjunctivitis in humans are thought partly to result from immunopathological responses to herpes simplex virus type 1 (HSV-1). The corneas of NIH mice were inoculated with HSV-1 (strain McKrae) and mice were examined for signs of disease and infection on days 1, 4, 7, 10, 14 and 21. The eyes and eyelids of infected and control mice were processed for immunohistochemistry and double stained for viral antigens and one of the following cell surface markers (Gr-1, F4/80, CD4, CD8, CD45R or MHC class II) or one of the following cytokines (IL-2, IL-4, IL-6, IL-10, IL-12 or IFN-gamma). All infected mice developed signs of HSK by day 4 and blepharitis by day 7 and these both persisted until day 21, when signs of resolution where apparent. Virus was detected during the first week of infection and became undetectable by day 10. Large numbers of Gr-1(+) cells (neutrophils) infiltrated infected corneas and eyelids in areas of viral antigen and CD4(+) T cells increased significantly in number after virus clearance. In both sites, the predominant cytokines were IL-6, IL-10, IL-12 and IFN-gamma, with few IL-2(+) and IL-4(+) cells. These observations suggest that the immune responses in the cornea are similar to those in the eyelids but, overall, the responses are not clearly characterized as either Th1 or Th2. In both sites, the neutrophil is the predominant infiltrating cell type and is a likely source of the cytokines observed and a major effector of the disease process.

Described in the paper are the results of examination of the local immunity in patients with demodectic blepharoconjunctivitis (DBC). Demodicosis of the eyes was established to develop in impairments of the local immunity described by a lower level of IL-4 in lacrimal fluid, a lower relative quantity of CD3+ cells, and a higher relative count of CD16+-lymphocytes infiltrating the eyelid-conjunctiva epithelium. The age-related immunodeficiency manifested as a decreased relative number of CD3+ and CD4+-lymphocytes infiltrating the eyelid-conjunctiva epithelium provokes a higher invasion of ticks and an increased morbidity of demodicosis among elderly people. DBC, when complicated by episcleritis or keratitis, is accompanied by a higher IgE level in lacrimal fluid and a decreased ratio of IgE/IL-4, which matters in prognostication and pathogenetic substantiation of DBC therapy.
