The purpose of this study is to evaluate the efficacy of Blink Tears and Systane used concomitantly with topical cyclosporine for the treatment of dry eye.

Study summary:

Dry eye is a chronic condition that is believed to afflict more than 3 million patients in the United States.1 Symptoms of dry eye are very bothersome and impact quality of life, reduce work capacity, and may result in poorer psychological health. Also, symptoms of dry eye are associated with a decreased ability to perform activities that require visual attention such as reading and driving a car.2 Patients with dry eye complain most frequently of a scratchy or sandy (foreign body) sensation. Other common symptoms are itching, excessive mucus secretion, inability to produce tears, a burning sensation, photosensitivity, redness, pain, and difficulty in moving the lids. In most patients, the most remarkable feature of the eye examination is the grossly normal appearance of the eye.3 Chronic dry eye disease is associated with an inflammatory mechanism mediated by activated T-cell lymphocytes3 which affects the ocular surface and lacrimal gland.4 The damage caused by dry eye disease may be irreversible, and despite the availability of various tear substitutes, many patients with dry eye syndrome experience corneal injuries with a subsequent reduction in vision.5 Cyclosporin A (Restasis®, Allergan, Irvine, CA) has been shown to significantly reduce the number of activated T-lymphocytes within the conjunctiva6, thereby minimizing the inflammation causing dry eye. Topical cyclosporin A 0.05% ophthalmic emulsion (Restasis®, Allergan, Irvine, CA) increases tear production and improves the quality of naturally produced tears and is the first approved therapeutic agent for the treatment of chronic dry eye and the only treatment modality that addresses the underlying pathology. In addition to topical therapy with cyclosporine, some patients continue to use artificial tears for occasional relief of residual symptoms. The choice of concomitant tear is important but little research has been published differentiating between the efficacy of these solutions when used concomitantly with topical cyclosporine.
