Adenoviral keratoconjunctivitis in a tertiary care eye clinic.

PURPOSE: To elucidate the natural history and epidemiology of adenoviral keratoconjunctivitis as seen in a tertiary care eye clinic. METHODS: In a retrospective observational case series design, the medical records of 54 consecutive patients seen over a 6-year period at the Dean McGee Eye Institute (DMEI) with a diagnosis of adenoviral keratoconjunctivitis were analyzed retrospectively. The main outcome measure was the duration of symptomatic subepithelial corneal infiltrates following onset of acute conjunctivitis. RESULTS: Annual case numbers ranged from 3 each in 1997 and 1998 to 26 in 2000. No more than 5 new cases presented in any single month, and no seasonal predominance was evident. The median duration of disease was 5 weeks, but the mean was 23.4 weeks, reflecting a subset of patients with a prolonged course. Indeed, 14 (25.9%) of 54 patients demonstrated symptomatic subepithelial corneal infiltrates for more than 45 days from the first examination for conjunctivitis. CONCLUSION: These data suggest a significant level of long-term morbidity for adenoviral keratoconjunctivitis.

Camphor-related self-inflicted keratoconjunctivitis complicating delusions of parasitosis.

PURPOSE: To report a case of camphor-related self-inflicted keratoconjunctivitis secondary to delusions of parasitosis. METHODS: A 61-year-old man with delusions of parasitosis suffered from camphor-related self-inflicted ocular trauma that manifested with corneal epithelial defects and secondary anterior chamber reaction. Two episodes of exacerbation of the ocular conditions related to the use of camphor occurred. The left eye had secondary infection with Sternotrophomonas maltophilia and Staphylococcus aureus in the second episode of exacerbation. RESULTS: The right eye recovered well with the treatment of topical lubricants and corticosteroids and had best-corrected visual acuity (BCVA) of 20/25. The infection of the left eye led to corneal perforation, necessitating penetrating keratoplasty; BCVA was hand motions because of a mature cataract. Olanzapine therapy for 1 month to decrease the delusions of parasitosis and 24-hour watch to prevent the use of camphor led to the resolution of self-inflicted keratoconjunctivitis in the patient. CONCLUSIONS: Delusions of parasitosis may lead to vision-threatening self-inflicted ocular trauma. This may be the first case report of pure camphor-related self-inflicted toxic keratoconjunctivitis.

Encephalitozoon hellem infection as the cause of a unilateral chronic keratoconjunctivitis in an umbrella cockatoo (Cacatua alba).

An umbrella cockatoo (Cacatua alba) was presented with a keratoconjunctivitis of 9 months' duration that was refractory to antibacterial and antifungal treatments. Microsporidian-type spores were observed in calcofluor M2R-stained cytological preparations of debrided corneal epithelium. Hematoxylin and eosin-stained sections of a conjunctival biopsy also showed a small number of intracellular parasites. Microsporidial DNA was detected by polymerase chain reaction in DNA extracted from the remaining biopsy material. Sequence analysis of the small subunit ribosomal RNA gene identified the microsporidium as Encephalitozoon hellem. The cockatoo was treated with oral albendazole for 3 months with resolution of the signs, and then again for 4 months when the signs returned. Since then, the bird has remained healthy for 2 years. This is the second report of a microsporidial keratoconjunctivitis in a bird, and the first report of an E. hellem infection in a cockatoo. Ophthalmologists should consider E. hellem as a possible cause of a keratoconjunctivitis in parrots that is refractory to treatment with traditional antimicrobials.

Treatment of menopausal keratoconjunctivitis sicca with topical oestradiol.

OBJECTIVE: To investigate the effect of 17 beta-oestradiol ophthalmic drops in comparison with a traditional tear substitute in postmenopausal women with keratoconjunctivitis sicca. DESIGN: Randomised prospective trial. SETTING: Menopause clinic. PARTICIPANTS: Eighty-four postmenopausal women suffering from keratoconjunctivitis sicca and necessitating a hormone replacement therapy (HRT) for general climacteric symptoms. METHODS: The women were randomised into two groups and were given 17 beta-oestradiol eye drops (n = 42, group 1) or a tear substitute (n = 42, group 2). Both groups received a systemic HRT. MAIN OUTCOME MEASURES: A Schirmer's test was performed immediately before the beginning of therapy and after four months. In addition, eye symptoms were assessed using a visual analogue scale. RESULTS: A comparison of visual analogue scores at four months in the women who received 17 beta-oestradiol eye drops versus those who received a tear substitute demonstrated a statistically significant difference in all observed ocular symptoms (P < 0.0001). The Schirmer's test revealed a significant difference of results before and after treatment in the oestradiol group (P < 0.0001) while in group 2 no significant difference was found. CONCLUSIONS: Our study demonstrates that topical oestrogen is successful in treating keratoconjunctivitis sicca while it seems that the blood-eye barrier prevents systemic oestrogens from acting on the conjunctivae.

Keratoconjunctivitis sicca and primary Sjögren's syndrome in a Danish population aged 30-60 years.

PURPOSE: To investigate the presence of keratoconjunctivitis sicca and primary Sjögren's syndrome a sample of 504 persons aged 30-60 years from Copenhagen was studied. METHODS: The presence of keratoconjunctivitis sicca and primary Sjögren's syndrome was estimated according to both the Copenhagen set of criteria and the preliminary European criteria. RESULTS: Symptoms of dry eye and oral dryness were very common and with no significant correlation to age or sex. Keratoconjuncitivis sicca was most frequent in persons aged 50-59 years and was equally common in men and women. Primary Sjögren's syndrome could only be diagnosed in one person according to the Copenhagen criteria (cut-off the Schirmer-1 test < or = 5 mm/5 min), and in three persons according to the preliminary European criteria. CONCLUSION: The frequency of keratoconjunctivitis sicca in persons aged 30-60 years in Copenhagen may be estimated to be 11% according to the Copenhagen criteria and 8% according to the preliminary European criteria. The frequency of primary Sjögren's syndrome in persons aged 30-60 years in Copenhagen may be estimated to be between 0.2% and 0.8% according to the Copenhagen criteria and between 0.6% and 2.1% according to the preliminary European criteria.

Clinical features and diagnosis of adult atopic keratoconjunctivitis and the effect of treatment with sodium cromoglycate.

This study describes 17 cases of atopic keratoconjunctivitis in adults. In 8 cases the clinical appearances were nonspecific and sufficiently different from vernal keratoconjunctivitis to make diagnosis difficult. These atypical cases often showed a fine papillary conjunctival reaction on the upper tarsus, subconjunctival scarring, and in 1 case severe symblepharon. Corneal features included corneal microcysts, peripheral vascularisation, and various patterns of punctate epithelial keratitis. It was therefore important to establish the atopic status of the patient. A personal or family history of other atopic disease was elicited in every case, and the diagnosis was confirmed by the detection of raised serum IgE level. Uncontrolled clinical assessment suggested that 10 out of 15 patients experienced improvement in symptoms with the use of 2% sodium cromoglycate eyedrops 4 times a day. A subsequent double-masked cross-over trial comparing the same treatment with a matched placebo preparation indicated that 6 out of 9 patients preferred sodium cromoglycate while 1 preferred the placebo. Two patients noted no difference. Cases showing nonspecific or atypical clinical features responded to treatment just as frequently as did cases of typical vernal keratoconjunctivitis.

Efficacy of nedocromil 2% versus fluorometholone 0.1%: a randomised, double masked trial comparing the effects on severe vernal keratoconjunctivitis.

AIMS: To compare the efficacy of topical nedocromil 2% with fluorometholone 0.1% in vernal keratoconjunctivitis (VKC). METHODS: In a double masked random design, 24 patients with severe vernal keratoconjunctivitis were placed at random on nedocromil 2% eye drops in one eye and fluorometholone 0.1% in the fellow eye. At the end of the 2 week treatment period, the patient crossed over the eye drops (if asymptomatic in one eye), or continued with nedocromil sodium in both eyes (if asymptomatic in both eyes). All patients were examined weekly and ocular surface temperature recorded for a period of 6 weeks. RESULTS: Improvement in the watering, discharge, conjunctival hyperaemia, papillary hypertrophy, and Trantas' dots was noted in both groups, but overall fluorometholone was significantly more effective than nedocromil. Eyes treated with fluorometholone showed a significant decrease in ocular surface temperature compared with nedocromil treated eyes (p = 0.03). CONCLUSIONS: Both nedocromil and fluorometholone were effective in ameliorating the signs and symptoms of vernal keratoconjunctivitis. No adverse effects were noted in the nedocromil group.

Keratoconjunctivitis sicca in the dog associated with the administration of salicylazosulphapyridine (sulphasalazine).

Thirteen cases of iatrogenic and bilateral keratoconjunctivitis sicca following the administration of the sulphonamide salicylazosulphapyridine (sulphasalazine) for the treatment of colitis were studied. No breed, age or sex incidence was noted in this series, unlike in keratoconjunctivitis sicca cases due to other causes. The lacrimotoxic effect of sulphasalazine was permanent except in one case and it is suggested that dogs on this drug should be monitored for tear secretion at regular intervals. Reports of a similar association between keratoconjunctivitis sicca and this drug and between the disease and other sulphonamides and compounds are discussed.

Use of exfoliative cytology in the diagnosis of ovine keratoconjunctivitis.

The cells present in the conjunctival sacs of 142 healthy sheep and 87 sheep with ovine keratoconjunctivitis were examined. The most numerous cells in the healthy conjunctival sacs were epithelial cells and occasionally lymphocytes; neutrophils were rarely present. Ovine keratoconjunctivitis was characterised by a rapid onset of acute inflammation of the conjunctiva, followed by hyperaemia of the sclera and pannus, and opacity of the cornea. The most numerous cells in the acute phase were neutrophils, and the presence of plasma cells was also suspected. The use of cytological methods to aid the detection of Mycoplasma conjunctivae, the organism most commonly isolated from cases of ovine keratoconjunctivitis in Britain are discussed.

Mycoplasmas and ovine keratoconjunctivitis.

The clinical course of an outbreak of keratoconjunctivitis in housed lambs and their dams was followed. Signs were transient generally and became severe in only a small proportion of lambs. The outbreak became most obvious when the lambs were 46 to 55 days old, when 46.9 per cent were affected. Mycoplasma conjunctivae isolations, confirmed by comparison with the type strain by biochemical and serological reactions, increased to 62.1 per cent of all eyes swabbed, but no correlation could be demonstrated between presence of the organism and clinical status. The reasons for this are discussed. Mycoplasma ovipneumoniae was also recovered from the eyes of a small number of lambs. Instillation of a broth culture of M conjunctivae into the conjunctival sacs of four hoggs produced a transient keratoconjunctivitis similar to that observed in the field, but no effect was observed in animals inoculated intravenously. M conjunctivae may therefore be the aetiological agent of non-follicular infectious ovine keratoconjunctivitis, although further work in gnotobiotic or specific pathogen free lambs is required to establish the fact beyond doubt.

Occurrence of keratoconjunctivitis apparently caused by Mycoplasma gallisepticum in layer chickens.

Natural cases of keratoconjunctivitis, apparently caused by Mycoplasma gallisepticum (MG), in layer chickens are described. The disease occurred in a commercial flock consisting of 36,000 pullets (Babcock), first appearing around 30 days of age. Clinically, affected chickens showed unilateral or bilateral swelling of the facial skin and the eyelids, increased lacrimation, congestion of conjunctival vessels, and respiratory rales. Some of the severely affected chickens closed their eyes. The morbidity reached 27.8%, and it was estimated that approximately 10% died from reduced feed intake due to impaired vision. Ten 70-day-old chickens with clinical diseases were examined for lesions. There was acute to subacute keratoconjunctivitis in all of the chickens, and some exhibited laryngitis. Adherence of mycoplasma organisms to epithelial cells of the conjunctiva, cornea, and larynx was frequently observed. These organisms had an ultrastructure characteristic of MG and showed a positive reaction with rabbit polyclonal antibodies against the S6 strain of MG by immunohistochemical analysis. MG was isolated from tissue homogenates of the eyelids and tracheas of the affected chickens. Many of the chickens had atrophic bursae, and infectious bursal disease virus antigens were detected in necrotic bursal follicles by immunostaining. Therefore, immunosuppression due to infectious bursal disease was implicated in the pathogenesis of keratoconjunctivitis in the present cases.

Incidence of ocular complications in rheumatoid arthritis and the relation of keratoconjunctivitis sicca with its systemic activity.

To investigate the incidence of ocular complications in patients with rheumatoid arthritis under modern modalities of treatment and find the relationship between its systemic activity and ocular complications, routine ophthalmological examinations were done as a prospective study in 111 consecutive patients including 89 inpatients and 22 outpatients with rheumatoid arthritis seen from April to May 1995, in a hospital with a special clinic for rheumatology. Keratoconjunctivitis sicca (secondary Sjögren's syndrome) was found in 19 patients (17.1%), scleritis in one patient (0.9%), central retinal vein occlusion in 2 patients (1.8%), and idiopathic retinal hemorrhage in 3 patients (2.7%). Patients with keratoconjunctivitis sicca had significantly higher titers of rheumatoid factor (Mann-Whitney's U-test, p = 0.0048), higher levels of IgM (p = 0.0484), and lower levels of HDL-cholesterol (p = 0.0191), compared to patients without it. The incidence of ocular complications was comparable to the previous studies and keratoconjunctivitis sicca should be considered in patients with high titers of rheumatoid factor.

A case of epidemic keratoconjunctivitis complicated by Alcaligenes xylosoxidans infection.

PURPOSE: To report a case of epidemic keratoconjunctivitis complicated by Alcaligenes xylosoxidans. METHODS: A 37-year-old man suffered epidemic keratoconjunctivitis in both eyes. Eleven days later, he developed a corneal ulcer in his left eye. Bacterial staining, culture, and antibiotics sensitivity test were performed from a corneal scrape. RESULTS: The cultures revealed a growth of Alcaligenes xylosoxidans, and the patient was treated with ceftazidime and levofloxacin, based on the sensitivity test results. After 21 days of treatment, the infection was resolved with mild scaring and final vision in the left eye of 20/20. CONCLUSIONS: Alcaligenes xylosoxidans should be considered a rare but potential pathogen able to produce comeal ulcer complication in epidemic keratoconjunctivitis.

Late onset of haze associated with viral keratoconjunctivitis following photorefractive keratectomy.

BACKGROUND: To report a newly recognized cause of late onset of corneal haze following photorefractive keratectomy (PRK). METHODS: A 35-year old woman who underwent uneventful PRK and subsequently developed viral keratoconjunctivitis 1 year after treatment. RESULTS: During resolution of the viral keratoconjunctivitis, the patient developed extensive central corneal subepithelial infiltrates and anterior stromal fibrosis in the PRK ablation zone. More than 1 year after the initial infection, the central subepithelial fibrosis persisted, complicated by myopic regression, central steep island on videokeratography, and loss of five lines of spectacle-corrected visual acuity. By the end of the second year after the infection, visual acuity had improved with disappearance of the central steep island on videokeratography. However, the myopic regression and subepithelial fibrosis remained. CONCLUSION: Patients who undergo PRK may be at greater risk of visual loss following viral keratoconjunctivitis secondary to persistent subepithelial infiltrates and/or stromal fibrosis within the PRK treatment zone.

A 10-year case report and current clinical review of chronic beta-hemolytic streptococcal keratoconjunctivitis.

BACKGROUND: Streptococcus is a common source of bacterial keratoconjunctivitis in adults. Affected patients often report decreased vision, foreign body sensation, redness, and a mucous discharge. Clinical signs reveal diffuse conjunctival injection, a conjunctival papillary response, corneal superficial punctate keratitis, and a mucopurulent discharge with corresponding visual acuity decrease. Culturing is mandatory in hyperacute cases and broad-spectrum treatment is advised until culture results are definitive. Recurrent cases may change in clinical appearance. Bacterial exotoxins may induce a severe inflammatory response as well. CASE REPORT: A case of bilateral recurrent bacterial keratoconjunctivitis in a 61-year-old man is reported, as well as a current clinical review of the literature. Aerobic culture yielded Streptococcus pyogenes, a beta-hemolytic group A streptococcus. After unsuccessful broad-spectrum antibiotic treatment with several agents, culture and sensitivity testing confirmed the diagnosis and adjustment of the treatment plan accordingly was successful. During the following 10 years, there were six episodes in the left eye and three episodes in the right eye with resultant inflammation and comeal pannus. Recent repeat culture and sensitivity testing showed that the streptococcus had changed to an atypical presentation. The university laboratory reported the findings to the State Department of Public Health, as this was a nonrespiratory isolate of group A streptococcus. CONCLUSION: Although culture is indicated in hyperacute bacterial keratoconjunctivitis, consider sensitivity testing in non-responsive cases. If the condition is recurrent and the clinical presentation appears different from previous episodes, suspect that the initial pathogen may be changing. Severe secondary inflammation may occur due to bacterial exotoxin reactions. Identification of the underlying causes is advised.

Cytologic diagnosis of adenoviral epidemic keratoconjunctivitis by direct immunofluorescence.

A direct immunofluorescence technique for the diagnosis of acute adenoviral keratoconjunctivitis and pharyngoconjunctivitis was found to be a reliable, sensitive, and specific technique for the detection of soluble adenoviral antigens in epithelial cells on conjunctival scrapings of patients with epidemic keratoconjunctivitis. Of 25 patients with clinical findings consistent with epidemic keratoconjunctivitis or pharyngoconjunctival fever, all had positive diagnostic scrapings by direct immunofluorescence.

[Isolation of chlamydia in keratoconjunctivitis].

Two isolates, identified as Chlamydia (neorickettsia) were obtained from the lacrimal secretion of calves with an acute infection on two of a total of four investigated farms with a record of infectious keratoconjunctivitis. In about 70% of the calves that survived there were complement-fixing antibodies against the neorickettsial antigen, the titers ranging from 1:8 to 1:64. Calves that yielded the causative agent were investigated in terms of the antibody dynamics. In the remaining herds no specific antibodies were demonstrated in animals that had survived. One of the isolated strains was used to infect (via the external camera oculi) a rabbit. Acute keratoconjunctivitis followed, and the blood serum of the rabbit was found to contain complement-fixing antibodies of a titer within the 1:8-1:16 range from the 30th day on. A neorickettsial strain was also isolated from the ocular secretion of a dog with serofibrinous keratoconjunctivitis, and this was regarded as a rarely encountered finding.

Rapid assay of lactoferrin in keratoconjunctivitis sicca.

We compared measurement of lactoferrin concentration by the LactoCard solid phase ELISA assay with the LactoPlate radial immunodiffusion assay in tears of normal patients and those with keratoconjunctivitis sicca. The LactoCard, a new lactoferrin assay, allows rapid determination of tear lactoferrin concentration in 10-15 min, a notable improvement over the 3 days required of the LactoPlate. There was no statistically significant difference between the accuracy of the two assays in normal patients nor in those patients with a diagnosis of keratoconjunctivitis sicca. Both assays showed a significant decrease in tear lactoferrin concentration in patients with severe keratoconjunctivitis sicca when compared to normal patients. The LactoCard is a rapid and reliable means of measuring tear lactoferrin concentration in a clinical setting.
