Filter by:The purpose of this study is to assess the efficacy and safety of T4020 versus vehicle.
This is a prospective, phase I-II, randomised, open-label clinical trial that will evaluate the safety and feasibility, as well as clinical efficacy evidence, of a bioengineered anterior corneal substitute in adults with severe trophic corneal ulcers. This model of human anterior allogeneic cornea will provide an alternative approach in cases where human donor keratoplasty is not an option.
This study is aimed at assessing the safety and the efficacy of two dose regimens of recombinant human nerve growth factor (rhNGF) eye drops solution compared to vehicle for inducing a complete healing of stage 2 (persistent epithelial defect) and 3 (corneal ulcer) neurotrophic keratitis
Corneal diseases are a major cause of blindness worldwide, and corneal infections are a substantial cause of blindness in Asia. The aim of the Asia Cornea Society Infectious Keratitis Study (ACSIKS) is to study infectious keratitis (corneal infections) in Asian countries, so as to improve strategies for prevention and treatment, and to reduce the burden of blindness in Asia. The first phase of ACSIKS is an 18-month observational study involving 11 eye hospitals in 8 Asian countries; these hospitals manage more than 6700 cases of corneal infections every year. From the first quarter of 2012, all patients with a corneal infection will be recruited and a standard ACSIKS protocol will be applied; this protocol includes the use of a common set of study forms and a suggested panel of microbiological examinations. However, each centre will be continue to treat their patients with the anti-infective therapy standard for their centre. Data will be recorded for each patient for a period of six months, including their medical and surgical management, the final clinical outcome and vision. Bacterial and fungal growths from patients will also be stored for further research during a second phase of ACSIKS. These studies will focus on evaluating the resistance of the most common bacterial infections to the current available antibiotics, performing DNA testing to compare our strains with bacterial infections in the West, and to developing new diagnostic tests and anti-infective therapies tailored to corneal infections in Asia.
This study is to develop a lamellar keratoplasty method for corneal ulcer using acellular corneal matrix (ACM) and to make an analysis among patients for its therapeutic effect.
CACICOL20 is a biodegradable nanopolymer engineered to mimic glycosaminoglycans such as heparan sulfates. Applied to the corneal lesion, it replaces damaged heparan sulfates in the matrix scaffold. CACICOL20 binds to matrix proteins such as collagen and cytokines or endogenous growth factors of the cellular microenvironment. CACICOL20 provides a protective function and restores the matrix architecture. This produces a suitable spatial environment for cells to respond properly to the cascade of signals needed for tissue regeneration to resume. The ophthalmic solution, CACICOL20, used for corneal ulcers is very well tolerated both locally and generally, as proved by a pilot study which as been conducted at the "Hôpital des XV-XX" in Paris (France). It reduces the pain significantly and increases corneal ulcer healing (all ulcers treated were resistant to all other usual therapies). Therefore, the accuracy of a Randomized multicentric double blinded study to evaluate the efficacy of CACICOL20 versus placebo for chronic corneal ulcer healing has been shown and will begin mid-may 2010. In this study, CACICOL20 will be applied every 2 or 4 days for 3 months. The aim of the study is a double blinded comparison of complete chronic corneal ulcers healing rate within 3 months in 3 groups of patient double blinded randomized between CACICOL20 instillations distribution and physiological salt solution instillations distribution. The main judgment criteria is healing rate within 3 months defined as corneal ulcer complete closure.
The goal of this study is to investigate the overall theory that the use of chemically preserved solutions associated with contact lenses promotes an increase in bacterial infection.
The purpose of this study is to determine if the addition of oral voriconazole to topical treatment regimens results in lower rates of perforation in severe fungal corneal ulcers.
The purpose of this study is to determine if natamycin or voriconazole results in better visual outcomes in fungal corneal ulcers, especially visual acuity.
The propose of this study is to determine the efficacy of 2% xylocaine in reducing pain due to subconjunctival antibiotic and antifungal injection.
