5 Clinical Trials for Various Conditions
This study is a non-interventional, observational study that will evaluate the natural history of corneal abrasions in patients with Dystrophic Epidermolysis Bullosa (DEB).
The researchers are trying to understand if the application of a bandage contact lens results in better relief than usual treatment for a corneal abrasion.
Two percent of all patients presenting to the Emergency Departments have complaints involving the eye. Corneal abrasions are a common diagnosis with patients with eye pain and often cause significant discomfort. Current treatment includes a thorough evaluation of the eye followed by patching, empiric antibiotics, cycloplegics and oral pain medicines. This study will be a randomized controlled trial to determine the safety and efficacy of BCLs. It will involve the initial patient evaluation followed by a return visit to the Emergency Department within 36 hours for re-examination. At each visit, the patient will be assessed for the size and location of the abrasion along with their report of pain using a visual analog scale. Data will be recorded on a standard data collection sheet. Telephone contact will be made at 30 days to ensure resolution of abrasion and that no complications ensued.
Corneal abrasion (CA) is one of the most common eye injuries, accounting for 10% of eye-related emergency visits.1 A 1985 survey showed that around 3% of all visits to US general practitioners were for corneal abrasions. In addition, in 2008, approximately 27,450 work-related eye injuries and illnesses occurred that caused missed time from work.1Due to the large number of nerve endings even small corneal injuries can produce significant pain. The discomfort is typically most pronounced in the first 24-48 hours, and in many cases showed a loss in time at work and disruption of daily activities. The current standard of care in the emergency department includes topical analgesia and antibiotics with a change to oral analgesics upon discharge. Despite the ineffectiveness of oral analgesics in treating CA pain, most physicians do not prescribe topical analgesics based on standard medical teaching. The study's aim is to further investigate the role of tetracaine in the outpatient management of CA utilizing models already established to ensure safety. To accomplish this investigators will employ a prospective, double blind, randomized control model to compare undiluted 1% tetracaine hydrochloride to normal saline in patients presenting to the ED with uncomplicated corneal abrasions. Tetracaine will be supplied in three plastic prefilled, commercially available vials, each containing 0.5 mL of preservative-free, undiluted 1% tetracaine hydrochloride (a total of 1.5 mL or approximately 50 drops will be provide to avoid overuse). Saline will also be supplied in three plastic prefilled, commercially available vials, plastic bullets. Follow up visits or calls will be provide at 48 hour to reevaluate symptoms an asses the patients perceived pain using VAS provided in participant introduction packet during the informed consent process.
The purpose of this study is to identify the incidence of scratches on the surface of the eye in children who cannot blink due to medication use and to identify how best to reduce the risk of a scratch on the surface of the eye when patients are using specific medicines.
