Summary on Grant Application Form |

The treatment of complex retinal detachment and related eye conditions currently features a combination of a vitreous substitute and intravitreal drug therapy. Failure inevitably leads to a profound loss of vision. The causes of failure include ineffective drug levels inside the eye and the unsuitability of current materials for prolonged use of vitreous substitutes.This project will result in the synthesis of a 'smart' block copolymer prodrug with drug(s) attached via biodegradable peptide spacers. The polymers will be suitable for use as a long-term vitreous substitute and will possess long-term biocompatibility with a capacity for sustained intravitreal drug delivery. The copolymer will be easily injectable below physiological temperature, but once in the eye, because of its 'smart' temperature responsive behaviour, it will form a gel. Biodegradation of the peptide side chains will result in sustained drug release and lead to the maintenance of therapeutic intravitreal drug levels. Satisfactory techniques for the evaluation of a drug-carrying vitreous substitute do not as yet exist. Therefore, it will be necessary to develop new models early in the project. With this in mind, the programme will develop new methods to evaluate the novel vitreous substitutes using current materials as bench marks.
