Development of an in vitro model for the anterior region of the eye

Aims

The objective is to develop an in vitro model of the front part of eye (cornea) which will replace a significant number of procedures carried out on live animal eyes worldwide. Live animals are currently used for many investigations on the eye. These include research into diseases causing blindness, such as keratoconus or Fuch's dystrophy, and the tests carried out by commercial companies to test new substances.

Method

In the proposed model, the cornea of cow eyes that are a by-product of the meat industry and would otherwise be thrown away, are maintained in a special chamber. They are supplied with nutrients which allow them to remain alive for several weeks. The model will be rigorously evaluated over a period of 30 days and the evaluation will include all cell types in the cornea. The transparency, thickness and permeability of the cornea will also be monitored and microscopy will be used to evaluate the fine structure of the cells. The results will be compared with currently available information on both human and animal corneas.

Implications for the 3Rs

It is intended that the model will be used for basic corneal research, medical corneal research and for commercial applications including toxicological testing. It is anticipated that the model will replace many procedures currently carried out on live animals.
