Filter by:The purpose of this study is to evaluate the efficacy of different concentrations of AC-170 compared to vehicle in the prevention of the signs and symptoms of allergic conjunctivitis in the conjunctival allergen challenge (CAC) Model.
The purpose of this study is to assess the ocular comfort and safety of olopatadine hydrochloride opthalmic solution. 0.7%.
The present study will test if administration of different concentrations of 1334H eyedrops will be effective in treatment of allergic conjunctivitis in people with 10 yrs of age or older.
To evaluate patient perceptions of Al-4943 in subjects with allergic conjunctivitis previously treated with a topical ocular anti-allergy leukotriene-release inhibitor medication.
The objective of this study is to evaluate the dose response, and efficacy of Mapracorat ophthalmic formulation compared to its vehicle for the prevention of symptoms and signs associated with allergic conjunctivitis using a conjunctival allergen challenge (CAC) model.
The purpose of this study was to evaluate ocular responses with different allergen provocation methods.
The purpose of this study is to evaluate the safety, efficacy, and dose response of brimonidine tartrate ophthalmic solution as compared to placebo in the prevention of allergen-induced conjunctival redness using a conjunctival allergen challenge (CAC) model. It is hypothesized that low-dose brimonidine tartrate ophthalmic solution will be more effective than vehicle in the prevention of conjunctival redness induced by conjunctival allergen challenge when instilled prior to the allergen challenge.
The purpose of this study was to evaluate subject perceptions of Olopatadine 0.2%, dosed once-daily, in subjects with allergic conjunctivitis and to record any adverse events as described by the subjects as a part of this post marketing surveillance study.
This study will investigate the safety and efficacy of olopatadine hydrochloride / ketorolac tromethamine fixed dose combination ophthalmic solution compared with olopatadine hydrochloride ophthalmic solution in patients with seasonal allergic conjunctivitis.
Vernal keratoconjunctivitis (VKC) is a bilateral, chronic, external ocular inflammatory disease of unknown cause. It is a fairly common disease in hot, dry environments, representing as much as 3% of severe ophthalmic diseases and up to 33% of all eye pathology seen among young patients in eye clinics in Central Africa. Symptoms and signs can persist for years with an important visual morbidity and social impact. Corneal changes (e.g. corneal ulcers) can be sight threatening, occurring in up to 10% of VKC children. Topical steroid therapy remains the current standard treatment, but in developing countries its use often is chronic and not medically supervised, potentially leading to bacterial infections, steroid-induced glaucoma and cataract. Chromoglycate drops have less side effects but lack the power to control a flare-up. Topical cyclosporine has the potential to offer an efficient but safer alternative to steroid drops in the management of VKC in an African setting. Its safety and efficiency in the management of vernal keratoconjunctivitis have been described in several uncontrolled studies and double-blind, placebo-controlled trials, but those studies were relatively small and involved populations outside Africa with predominantly palpebral and mixed forms of VKC. Controversy still remains on the efficiency of cyclosporine in severe forms of allergic conjunctivitis like VKC. We therefore undertake a larger prospective randomized double-masked, standard treatment controlled clinical trial in Central Africa to compare the short-term efficiency of cyclosporine A (CsA) 2% eye drops, solved in olive oil vehicle, with that of steroid drops in predominantly limbal forms of VKC. During 4 weeks the participants will be randomised to either cyclosporine or dexamethasone as attack treatment for VKC. The 4 weeks thereafter all participants will receive chromoglycate drops as maintenance treatment. Additional objectives are to document any difference in rebound phenomenon while on chromoglycate during the maintenance phase between the 2 treatment groups and to evaluate safety and tolerance of the test medication.
