Abstract:
PRECIS:Rabbit model studies suggested better morphology blebs with equal intraocular pressure (IOP) efficacy as a standard mitomycin C (MMC) trabeculectomy using a novel slow-release drug delivery antifibrotic system delivering small quantities of MMC and 5-fluorouracil (5-FU). PURPOSE:To evaluate 2 different concentrations of biodegradable poly(lactic-co-glycolic acid) (PLGA) system with 5-FU and MMC (ElutiGLASS) for their ability to reduce fibrosis and compare the results with standard trabeculectomy with MMC in a rabbit model. MATERIALS AND METHODS:New Zealand albino rabbits (19) were divided into 3 groups (A, B, C) and standard trabeculectomy operation was performed in the right eye of each rabbit.Group (A) had trabeculectomy with MMC (0.4 mg/mL) applied using a Weck cell sponge; (B) trabeculectomy with slow-release ElutiGLASS (0.23 mg, 5-FU/0.33 μg MMC released over 23 to 30 d); (C) trabeculectomy with rapid release ElutiGLASS (0.45 mg of 5-FU/0.65 μg MMC, released over 5 to 7 d). The rabbits were followed for 3 months before euthanasia. RESULTS:Bleb morphology, vascularity, and fibrosis were less pronounced in groups B and C when compared with group A at 3 months. Group B appears to have a lower and more diffuse bleb appearance compared with the other 2 groups with honeycomb appearance on both clinical examination and ultrasound biomicroscopy imaging with higher percentage of maintained bleb space (83%), less fibrosis than group A while maintaining the same low inflammation score as the other 2 groups on histology. At 3 months, the PLGA polymer had completely disappeared in all rabbits. There were no statistical differences in the degree of IOP reduction or histologic inflammation, among the 3 groups. CONCLUSIONS:We successfully created a sustained-release antifibrotic drug delivery system that delivered known dosage of the drugs at doses that are significantly lower than the current standard, and resulted in less fibrosis while maintaining a healthy bleb and equal reduction of IOP. TRANSLATIONAL RELEVANCE:These results are supportive of the antifibrotic effect of the slow-release drug delivery system used in conjunction with trabeculectomy, thus paving the way for human pilot studies to improve and simplify existing surgical techniques for filtering surgeries in glaucoma.
