Microsporidial keratoconjunctivitis in a patient with AIDS.

A male patient is described with acquired immune deficiency syndrome (AIDS) who developed chronic keratoconjunctivitis and chronic sinusitis due to infection with the microsporidian Encephalitozoon cuniculi. Diagnosis was confirmed by electron microscopic examination of conjunctival epithelial cells and nasal polypectomy specimens. Treatment with propamidine isethionate 0.1% (Brolene) eye drops six times daily led to a prompt resolution of the keratoconjunctivitis.

Manchineel keratoconjunctivitis.

The Manchineel tree is an evergreen widely distributed in tropical regions. The toxic nature of Manchineel has been known since the early sixteenth century. Contact with its milky sap (latex) produces bullous dermatitis and acute keratoconjunctivitis. We identified 19 patients who had ocular injuries caused by Manchineel between 1985 and 1990 and were able to review 12. All of these patients had been treated by lavage, cycloplegia, and topical antibiotics. Of 20 episodes of exposure 14 affected both eyes. The cornea was damaged in 16 episodes, the extent varying from large corneal epithelial defects to superficial punctate keratitis. The epithelial changes had resolved in a mean period of 3.75 days (range 1 to 14 days). Two episodes caused stromal infiltration to appear and in one of these a stromal opacity remained 5 years later. The final visual acuity was 6/9 or better in all eyes except in one patient who had visual impairment because of glaucoma. Our results suggest that despite the severity of the acute reaction, the long term visual prognosis is excellent in Manchineel keratoconjunctivitis. The historical and toxicological literature on Manchineel is reviewed.

The aetiology of a keratoconjunctivitis occurring in goats in the Sudan.

An infectious keratoconjunctivitis occurring in goats in the Sudan is described. Experimental transmission using infective ocular discharges resulted in a conjunctivitis in young kids and a severe keratoconjunctivitis in an adult goat. A pleomorphic organism which resembled Rickettsia spp was found in conjunctival smears from naturally and experimentally infected animals. Neither Mycoplasma nor Chlamydia spp were isolated in microbiological cultures.

Keratoconjunctivitis in a hill sheep flock.

Keratoconjunctivitis affected many ewes on a large, experimental husbandry, hill farm in early and midwinter in two consecutive years. Small sporadic outbreaks occurred among ewes during the following winters and among ewes and lambs in the summer and autumn. Mycoplasma conjunctivae was isolated from conjunctival swabs taken from affected sheep. Keratoconjunctivitis had not been recognised on the farm before and the infection was probably introduced with purchased rams. Prompt treatment prevented blindness; a single application of aureomycin topical powder with an intramuscular injection of a long acting oxytetracycline was an effective clinical treatment. Prophylactic treatments with aureomycin powder did not prevent the spread of the disease. The outbreak appeared to have no effect on the weaning percentage and blackface and Cheviot ewes were equally susceptible.

Treatment of keratoconjunctivitis sicca in dogs with cyclosporine ophthalmic ointment: a European clinical field trial.

The results are reported of a six-week clinical trial of the efficacy of 0.2 per cent cyclosporine ophthalmic ointment for the treatment of chronic idiopathic keratoconjunctivitis sicca in dogs in the United Kingdom, Germany and France. The 87 dogs were referral cases with a history of chronic unresponsive keratoconjunctivitis sicca of which the aetiology was unknown, and they had to meet stringent criteria before being included in the trial. The clinical response to the therapy was monitored after seven, 21 and 42 days and the results for the right and left eyes were analysed separately. There was a statistically significant increase in lacrimal secretion throughout the study, with most of the increase occurring during the first week of treatment. The percentage of eyes with improved lacrimal secretion was higher in the dogs with initial Schirmer tear test values > or = 2 mm/min than in those with initial values of 0 or 1 mm/min. The observed steady improvement in conjunctival health was not always correlated with an improvement in lacrimal secretion. The incidence of blepharospasm, other signs of discomfort and corneal oedema decreased significantly during the study. No improvement in corneal vascularisation or pigmentation was observed during the six-week trial. Overall, 76 per cent of the left eyes and 87 per cent of the right eyes were considered to have improved at the end of the treatment period. No serious adverse reactions were observed and only mild irritation was noticed by the owners immediately after the application of the ointment. This irritation resulted in the recording of an adverse reaction at the scheduled observations in only three cases.

Epidemiological and microbiological study of an outbreak of infectious keratoconjunctivitis in sheep.

After several thousand sheep had been imported from Australia and New Zealand to Croatia during 1995, many native sheep that had been in contact with the imported animals acquired a severe ocular disease closely resembling infectious keratoconjunctivitis. In affected flocks glucose-fermenting mycoplasma were isolated from 48 per cent of conjunctival swabs and Branhamella ovis from 58 per cent. Twelve of 42 culturally and biochemically identical isolates were identified as Mycoplasma conjunctivae by polymerase chain reaction. From the conjunctivae of two animals M conjunctivae and M arginini were isolated in mixed culture. For many reasons most farmers removed the imported animals from their flocks and only sporadic cases of the disease were recognised in 1996. At the end of 1997, six flocks which were clinically free of the disease but had been affected during 1995, and five flocks with no history of the severe ocular disease were examined clinically and microbiologically, and were found to be free of M conjunctivae infection. At the time, B ovis was cultured almost exclusively from sheep originating from flocks which had been affected during 1995 and/or 1996. It was usually isolated in pure culture or as the predominant bacterial species, and was often accompanied by mild conjunctivitis. There were no microbiologically confirmed new cases of infectious keratoconjunctivitis during 1998 and 1999.

[Nosocomial and community outbreak of epidemic keratoconjunctivitis in Navarra in 1996].

BACKGROUND: Epidemic keratoconjunctivitis is an acute, generally bilateral infection, that appears sporadically or in outbreaks from a source of common infection which may be a visit to the ophthalmologist or a swimming pool. Keratitis may evolve to form sub-epithelial injuries in the cornea lasting as much as several months. METHODS: Description of an outbreak of epidemic keratoconjunctivitis that took place in Navarra (Spain) between April and August 1996 and which affected at least 266 people. RESULTS: The epidemiological research highlights the existence of two ophthalmologist consulting rooms as the transmission mechanism for the infection in 46 of the 116 patients researched. The spread of the infection in the environment of the patients was recorded in 119 cases, 62 of which are considered secondary cases. The aetiological diagnosis of the outbreak was carried out 11 days after the start of the microbiological research, isolating adenovirus in conjunctival samples of 8 of the 19 patients researched. CONCLUSIONS: The preventive measures taken to control the outbreak and their effectiveness was highlighted by the gradual reduction in cases.

Keratoconjunctivitis of the koala, Phascolarctos cinereus, caused by Chlamydia psittaci.

Chlamydia psittaci was cultured from 29 of 35 koalas (Phascolarctos cinereus) with keratoconjunctivitis. The disease progressed from acute to chronic stages over some months, with a known duration of at least 2 years. One recovered carrier was found. Up to 29% of koalas in some populations were clinically affected. A seasonal spread of infection was indicated by the high percentage of acutely affected cases found in summer. There was no evidence of susceptibility being related to age or sex. The sera of all chronically affected koalas had complement fixation test titres against chlamydial group antigen of 80 or above; in acute cases the titre ranged from 0 to 320. Of normal koalas, 84% were serologically negative, 16% had chlamydial antibody. A titre of 80 or more considered in conjunction with ocular disease could be taken as presumptive evidence of a chlamydial etiology. Chlamydial keratoconjunctivitis may be the ocular disease which was associated with the decline of koala numbers between the years 1885 and 1930.

[Phlyctenular keratoconjunctivitis and lymph node tuberculosis].

It is presented 28 cases of tuberculous keratoconjunctivitis from which 13 cases appears between 4-13 years at children with primary tuberculosis. All patients have a positive tuberculin skin test, a family or personal history of tuberculosis. Many of them have perihilar or cervical adenopathy and radiological evidence of a healed pulmonary tuberculous lesion. We report a case of tuberculous adenopathy with histopathological examine and tuberculous adenopathy with histopathological examine and tuberculous keratoconjunctivitis. Anti-tuberculous treatment was with isoniazid, pyrazinamide, rifampicin in cases with primary tuberculosis. The rest of patients was treated with topical medicine.

Microvascular submandibular gland transfer for severe cases of keratoconjunctivitis sicca.

Free submandibular salivary gland transfer was investigated as a surgical method for the treatment of severe keratoconjunctivitis sicca. In an animal model, we examined the tolerance of warm ischemia of the submandibular gland. After temporary interruption of the blood supply (1 to 6 hours), the morphologic changes in the submandibular gland were analyzed histologically and immunohistochemically in 41 rabbits. From 1.5 hours ischemia onward, an increasing structural damage of the parenchyma with emphasis on the secretory cells was seen. Six hours of ischemia caused total necrosis of the salivary gland. Our clinical experience includes 24 highly selected patients suffering from keratoconjunctivitis sicca, in whom we transferred 31 autologous submandibular glands to the temple for permanent autologous tear substitution within the past 4 years. The glands were implanted into a pocket prepared in the temporalis muscle, and the nourishing vessels were anastomosed to the superficial temporal artery and vein. The submandibular duct was implanted into the upper lateral conjunctival fornix. The transferred glands were left denervated. In addition to the clinical examination, scintigraphy with Tc 99m pertechnetate was used to document the graft's viability after the transfer. Viable incorporation with longstanding secretory function occurred in 26 of the 30 transplanted denervated salivary glands. The resulting lubrication of the treated eyes was irregular for up to 3 months in almost even case. One year after surgery, all patients with a viable transplant developed at least occasional epiphora, which was surgically managed by reducing the size of the graft in 10 patients. No severe side effects were seen in this series. The ophthalmologic evaluation of the method included the assessment of dry eye symptoms and of the volume and quality of ocular lubrication (Schirmer test, fluorescein break-up time), the pathology of the ocular surface (rose bengal staining), and the need for pharmaceutical tear substitutes. One year after surgery, 18 of 27 cases assessed were judged as significantly improved by these tests.

A case of keratoconjunctivitis due to Ewingella americana and a review of unusual organisms causing external eye infections.

We report the isolation of Ewingella americana from the conjunctivae of a 38 year old female physician with keratoconjunctivitis associated with the use of soft contact lens. The patient was treated successfully with topical ciprofloxacin. The source of the infection remains unknown. All contact lens cleaning materials used by the patient were sterile. Since the patient was a physician, and this organism has been recorded as a cause of nosocomial infections, we checked whether cases of Ewingella americana had been reported, but none were identified. We have identified 39 bacterial species, 27 fungi, 4 viruses, 7 protozoa, 4 helminths, and 2 arthropods which rarely have been associated with keratitis or conjunctivitis. Infectious diseases specialists and ophthalmologists must be aware of the many different causes of this illness, including Ewingella americana. This organism is a rare bacterial cause of keratoconjunctivitis not previously reported in Brazil. It should be added to the list of unusual cases of external eye infections.

[Nonpreserved topical steroids and lacrimal punctal occlusion for severe keratoconjunctivitis sicca].

PURPOSE: To analyze the efficacy of topical nonpreserved steroids before punctal occlusion in the treatment of severe keratoconjunctivitis sicca associated with Sjögren's syndrome. METHODS: We performed a prospective study including 15 patients, 30 eyes, (group 1) treated with topical nonpreserved steroids for 2 weeks and then punctal occlusion, and 15 patients, 30 eyes, (group 2) treated directly with punctal occlusion. Symptom severity (0-3+) and corneal fluorescein staining (0-9+) were evaluated after a week and after two months, and results were statistically compared between both groups with the t Student test. RESULTS: Symptom severity was negative in 67% of patients of group 1 and in 27% of patients of group 2 (p=0.0001 ) after a week, and in 80% of patients in group 1 and in 33% of patients of group 2 (p=0.0003) after 2 months. Corneal fluorescein staining was negative in 67% (OD) and 73% (OI) of patients of group 1 and in 33% (AO) of patients of group 2 (p=0.0001, AO) after a week, and in 80% (AO) of patients of group 1 and in 60% of patients of group 2 (AO) (p=0.0001, AO) after 2 months. There were no patients with side effects or complications. CONCLUSIONS: Topical nonpreserved steroid therapy for two weeks before punctal occlusion is effective in controlling symptoms and corneal fluorescein staining in patients with severe keratoconjunctivitis sicca associated with Sjögren's syndrome.

Effect of cyclosporine on conjunctival mucin in a canine keratoconjunctivitis sicca model.

PURPOSE: To test the hypothesis that beneficial effects of Cyclosporin A (CsA; Sandimmune; Sandoz, Basel, Switzerland) in treating keratoconjunctivitis sicca (KCS) include an effect on the mucin-producing conjunctival goblet cells independent of CsA's effect on lacrimation. METHODS: Keratoconjunctivitis sicca was induced bilaterally in six dogs after removal of orbital and nictitans lacrimal glands. Two weeks after induction of KCS, either 2% CsA or vehicle was applied twice daily to each surgically altered eye until 6 weeks after KCS induction. Eyes of three control dogs without surgically altered eyes were treated twice daily with vehicle only. Incisional biopsy specimens of ventral fornix conjunctiva were collected before gland removal (baseline) and at 2, 4, and 6 weeks after KCS induction. At each sampling time, eyes were photographed, and color images were subsequently graded for degree of conjunctivitis and characteristics of ocular discharge. Intracellular mucin stores in conjunctival epithelia were estimated using computer-assisted morphometry of biopsy specimen cross sections, and clinical and morphometric findings were correlated. RESULTS: Lacrimal gland removal resulted in induction of KCS in dogs by 2 weeks, with mean Schirmer tear test (STT) values of 5 mm/min or less occurring in surgically altered eyes compared with STT values of 22.5 mm/min before surgery and 22.9 mm/min in unaltered control eyes at 2 weeks. In surgically altered eyes, STTs remained low during the 6-week study, independent of topical treatment. Intracellular mucin stores were quantified from conjunctival samples collected from each eye at baseline and 2, 4, and 6 weeks. At 4 and 6 weeks (after 2 and 4 weeks of topical treatment), intraepithelial mucin quantities were significantly greater (P: < 0.05) in CsA-treated KCS eyes (14.4 and 13.1 microm(2)/microm, respectively) compared with pretreatment KCS (7.4 microm(2)/microm) eyes and vehicle-treated KCS eyes (7.3 and 8.5 microm(2)/microm, respectively). KCS eyes treated with CsA had lower conjunctivitis and ocular discharge scores than did vehicle-treated KCS eyes. CONCLUSIONS: Topical 2% CsA restored in vivo conjunctival mucin stores to control levels over a 4-week period, determined by computer-assisted morphometry of sequential conjunctival biopsy specimens from eyes of dogs with surgically induced KCS. Degree of conjunctivitis and severity of mucus discharge were decreased in KCS eyes treated with CsA. Because lacrimal tissues were removed from animals in this study, conjunctival responses occurred independent of lacrimogenic effect(s). These results indicate that restoration of conjunctival goblet cell mucin production, i.e., the balance between synthesis and secretion of mucin glycoproteins, may play an important role in the beneficial effect of CsA in treating KCS.

Recurrent phlyctenular keratoconjunctivitis: a forme fruste manifestation of rosacea.

BACKGROUND: Phlyctenular keratoconjunctivitis represents a delayed type hypersensitivity response to a systemic antigen within the body. METHODS: We present a case of symptomatic, recurrent, phlyctenular keratoconjunctivitis in an 8-year-old child. The patient's inflammation responded favorably to topical steroids at each episode, but no specific antigen could be identified. CONCLUSION: After observing the father's erythematous facial lesions, we attributed the child's ocular inflammation to rosacea (as a forme fruste manifestation) and treated her with systemic erythromycin. The symptoms were rapidly relieved and the disease process was arrested.

New genome type of adenovirus serotype 19 causing nosocomial infections of epidemic keratoconjunctivitis in Japan.

Twelve strains of adenovirus serotype 19, isolated from cases of epidemic keratoconjunctivitis in Japan in 1992, 1993, 1997, and 1998, were analyzed by DNA restriction analysis, using restriction endonucleases BamHI, BglI, BglII, EcoRI, HindIII, KpnI, PstI, SacI, SalI, SmaI, and XhoI. Among these 11 restriction endonucleases, EcoRI, PstI, SacI, and SmaI were discriminative enzymes, showing restriction patterns different from those reported previously for the prototype and the variant 19a. This new genome type was isolated in 1997 and 1998, when an increase of epidemic keratoconjunctivitis cases caused by adenovirus serotype 19 was observed for both sporadic and nosocomial infections. Strains from 1992 and 1993 showed restriction patterns similar to those of the worldwide reported variant 19a for all enzymes used. The changes detected in strains from 1997 and 1998 could be the reason for the recent epidemic.

Effects of buprenorphine on immunogenicity and protective efficacy in the guinea pig keratoconjunctivitis model (Sereny test).

Shigellosis is a disease of global proportions, with an estimated 164.7 million episodes annually throughout the world as well as an estimated 1.1 million associated mortalities in developing countries. Due to increasing incidence, and continued emergence of multi-drug resistant strains, Shigella vaccine development is considered a top public health priority. The guinea pig keratoconjunctivitis model, the basis for the Sereny test, remains the most reliable in vivo indicator of virulence of Shigella strains and immunogenicity and protective efficacy of Shigella vaccine candidates. The model is effective in evaluating the ability of Shigella strains to invade the corneal epithelia of guinea pigs and spread to contiguous cells, with the more virulent strains causing ulcerative keratoconjunctivitis. However, analgesia is not routinely used to relieve this painful condition because of potential immunomodulation and confounding of experimental results. The objective of the study reported here was to evaluate use of buprenorphine hydrochloride as an analgesic during the Sereny test. Local and systemic immune responses were measured in guinea pigs given buprenorphine versus those responses in controls. Results of this study suggest that buprenorphine, administered at an analgesic dose of 0.05 mg/kg of body weight twice daily, can be successfully used with the model without significantly affecting immunologic evaluation of Shigella vaccine candidates. However, in buprenorphine-treated animals, there was a significant increase in the amount of mucopurulent ocular discharge, requiring frequent cleaning of the affected eyes. Additionally, animals treated with buprenorphine had significant reduction in body weight, in comparison with saline controls.

Microvascular submandibular gland transfer for severe keratoconjunctivitis sicca: operation key points, prevention and management of complications.

OBJECTIVE: To summarize operation key points, prevention and management of complications in vascularized autotransplantation of submandibular gland for treatment of severe keratoconjunctivitis sicca. METHODS: 23 patients with severe keratoconjunctivitis sicca were treated by this procedure. Postoperative (99m)Tc images, follow-up studies, and management of complications were performed. RESULTS: The transplantations were successful in 19 cases, whose symptoms of xerophthalmia disappeared. The patients could stop applying artificial tears. In 4 patients the transplanted glands did not survive. Epiphora occurred in 5 cases. They were successfully treated by reducing the size of the graft. Obstruction of the Wharton's duct took place in one case and was treated by reconstructing the duct. When the superficial temporal vein was too small, venous bridging was applied. To select a relevant vein for anastomosis, blood oozing from the three veins was carefully inspected prior cutting off the gland when the external maxillary artery was preserved and was infused with heparin after the gland had been freed. CONCLUSIONS: If every point has been properly managed, the successful rate of operation could be warranted.

[Two cases of primary biliary cirrhosis accompanied with severe keratoconjunctivitis sicca due to Sjögren syndrome].

BACKGROUND: Primary biliary cirrhosis(PBC) is occasionally associated with Sjögren syndrome and results in liver cirrhosis. It occurs particularly in women, middle-aged or older, and is characterized by the presence of anti-mitochondrial antibody (AMA). We diagnosed PBC in 2 patients with severe keratoconjunctivitis sicca (KCS). CASE 1: A 45-year-old woman was diagnosed with PBC. A test for the presence of AMA was positive and liver dysfunction was detected. Tests for the presence of anti-SSA antibody and anti-SSB antibody were also positive. Signs of severe sicca syndrome observed in the oral cavity and in the eyes were compatible with signs of Sjögren syndrome. Furthermore, superior limbic keratoconjunctivitis was also observed. CASE 2: A 57-year-old woman was diagnosed with PBC and Sjögren syndrome. She also had thyroiditis and severe KCS. Tests for the presence of AMA, anti-SSA antibody, and anti-SSB antibody were positive. In both cases, eye drops were not effective as a treatment for the KCS, but lacrimal punctal occlusion with cauterization was effective. CONCLUSION: PBC should be looked on as a disease that may possibly promote severe KCS.
