MMP-8 concentration and activation degree in tear fluid are increased in OcR, probably reflecting increased inflammatory activity. Doxycycline effectively reduces these pathologically excessive levels and activation of MMP-8, and relieves patients' subjective symptoms.
ABSTRACT.Purpose: To evaluate the efficacy and effect of tacrolimus ointment on conjunctival cytology in patients with atopic blepharoconjunctivitis or keratoconjunctivitis. Methods: Ten patients with severe atopic blepharoconjunctivitis treated with 0.03% tacrolimus ointment once daily as an intermittent treatment were analysed retrospectively. The main outcome measures were clinical response to topical tacrolimus, adverse events and changes in the inflammatory cells obtained from conjunctival brush samples. Results: Marked clinical responses in blepharitis and conjunctivitis symptoms were seen after a mean follow-up time of 6 weeks. Clinical scores decreased by 67% in blepharitis and 74% in conjunctivitis symptoms. No severe adverse events or signs of immunosuppression such as herpes simplex infections occurred. No significant changes occurred in visual acuity, refraction, anterior chamber, retina or intraocular pressure. Median decreases were 85% (p ¼ 0.01) in conjunctival eosinophils, 50% (p ¼ 0.01) in neutrophils and 58% (p ¼ 0.02) in lymphocytes. Conclusions: Tacrolimus ointment is potentially a safe and effective treatment for atopic blepharoconjunctivitis. Regular treatment of the eyelids once daily may also lead to clinical and cytological improvement of the conjunctivitis.
Allergic diseases have greatly increased in industrialized countries. About 30% of people suffer from allergic symptoms and 40%–80% of them have symptoms in the eyes. Atopic conjunctivitis can be divided into seasonal allergic conjunctivitis (SAC) and perennial allergic conjunctivitis (PAC). The treatment of SAC is simple; antihistamines, anti-inflammatory agents, or chromoglycate. In severe cases of SAC, subcutaneous or sublingual immunotherapy is helpful. PAC needs longer therapy, often year round, with mast cell stabilizers, antihistamines, and sometimes local steroids. Atopic keratoconjunctivitis is a more severe disease showing chronic blepharitis often connected with severe keratitis. It needs, in many cases, continuous treatment of the lid eczema and keratoconjunctivitis. Blepharitis is treated with tacrolimus or pimecrolimus ointment. Conjunctivitis additionally needs corticosteroids and, if needed, cyclosporine A (CsA) drops are administered for longer periods. Basic conjunctival treatment is with mast cell-stabilizing agents and in addition, antihistamines are administered. Vernal keratoconjunctivitis is another chronic and serious allergic disease that mainly affects children and young people. It is a long-lasting disease which commonly subsides in puberty. It demands intensive therapy often for many years to avoid serious complicating corneal ulcers. Treatment is mast cell-stabilizing drops and additionally antihistamines. In relapses, corticosteroids are needed. When the use of corticosteroids is continuous, CsA drops should be used, and in relapses, corticosteroids should be used additionally. Nonallergic eosinophilic conjunctivitis (NAEC) is a less known, but rather common, ocular disease. It affects mostly middle-aged and older women. The eye symptoms of NAEC are largely similar to those seen in chronic allergic conjunctivitis. Basic therapy is mast cell-stabilizing drops. Eosinophilic inflammation needs additional corticosteroids. In severe cases, CsA drops are recommended. Antihistamines should be avoided. It is important to recognize the different forms of allergic ocular diseases and to start the treatment early and intensively enough to avoid chronicity of the disease and accompanying tissue destruction.
ABSTRACT.Purpose: To determine the concentration of group IIA phospholipase A 2 (GIIAPLA 2 ) in tears of patients with ocular rosacea, and to compare it with GIIAPLA 2 concentration in tears of age-matched healthy controls. Methods: The GIIAPLA 2 concentration in tears was measured with a timeresolved fluoroimmunoassay in 21 patients with ocular rosacea (mean age 55.6±9.2 years) and in 21 normal subjects (mean age 53.4±8.2 years). Conjunctival brush cytology was carried out and eosinophils, neutrophils, lymphocytes, squamous epithelial cells, columnar epithelial cells, metaplastic changes and goblet cells were calculated separately. Results: The GIIAPLA 2 concentration in tears was statistically significantly lower in patients with ocular rosacea (31.0±18.4 mg/ml, p=0.0099) and, more specifically, in patients who had dry eye (25.8±15.1 mg/ml, p=0.0034), compared to that in normal controls. There was no correlation between the GIIAPLA 2 content of tears and the conjunctival cells collected by the brush cytology. Conclusion: The tears of patients with dry eye symptoms due to ocular rosacea have decreased GIIAPLA 2 content. The pathogenic importance of this finding is discussed.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
