Active clinical trials for "Conjunctivitis, Allergic"

Evaluating the percentage of patients that suffer from eye allergies and determining whether they also have dry eyes.

Ambrosia is known for its allergenicity in the USA causing hay fever and asthma. Israel has always been considered "clean" of Ambrosia but over the past years growth of Ambrosia plants has been detected in several locations in Israel. In the proposed study, patients referred for routine allergic evaluation will also be skin tested with Ambrosia allergens, in addition to their regular prick skin tests with all other airborne allergens.

The aim of the study is to find out if allergic diseases can be prevented buy giving probiotic bacteria to pregnant mothers and their newborn infants

This study will gather information on allergic rhinoconjunctivitis from surveys completed by adults and children.

By measuring and comparing the corneal biomechanical parameters of normal people, patients with allergic conjunctivitis, keratoconus, whether allergic conjunctivitis causes changes in corneal biomechanics can be explored, and sensitive mechanical indicators of allergic conjunctivitis can be identified. Furthermore, through rubbing frequency, ocular allergic symptom scores and physical sign scores observation, corneal morphological parameters, corneal epithelial thickness, tear inflammatory cytokines levels, and conjunctival microvascular parameters measurements, related factors affecting corneal biomechanics in patients with allergic conjunctivitis can be identified. Otherwise, by comparing corneal biomechanical changes in vernal keratoconjunctivitis before and after drug treatment, biomechanical change tendency during treatment can be clarified.

Background and purpose: Allergic conjunctivitis has increased alarmingly in recent years. The objectives of the study are: 1) To establish the safety and efficacy of applying eyewashes in spray form as monotherapy on the symptoms and signs of allergic conjunctivitis; 2) To establish the comparative efficacy with other eye drops as antihistamines; 3) To measure the modification of immunoglobulin E (IgE) and matrix metalloproteinase 9 (MMP9) levels in the tears.

To evaluate the therapeutic effects of dermatologic tacrolimus ointment on eyelids to treat refractory vernal keratoconjunctivitis and atopic keratoconjunctivitis.

This study is the first multi-center cross-sectional study on the diagnosis and misdiagnosis of allergic conjunctivitis in the ophthalmology clinic in China. It provides a clinical basis for the standardized diagnosis and treatment of allergic eye diseases.

The ocular surface may be the seat of an inflammatory process in many pathology as vernal keratoconjunctivitis. It has been shown that inflammatory cytokines produced by the cells themselves and the constituent cells of the target organ, are the main factors that cause inflammation. The main objective of our study was to compare the concentration of 40 cytokines in vernal keratoconjunctivitis and in control subjects.
