Understanding the structure of the human retina is important for understanding normal visual function. The goal of this study is to supply data on the distribution, density and connectivity of nerve cells in the human retina. Our study will provide a foundation for areas of clinical investigation of the human retina.
We will investigate changes in the retina secondary to disease process and try and modify them to allow a longer time frame for intervention. These changes (remodelling) are detrimental to visual function and the effectiveness of measures aimed at restoring vision, eg, bionic eye.

Summary
Our goal is to determine the numbers and types of nerve cells in the human retina: the part of the eye where visual processing starts. This data will serve as a baseline against which effects of visual disease can be measured.

Summary
The development of treatments that restore vision assumes that the output neurons of the retina remain intact. Yet, there is now considerable evidence that the neurons that signal from the retina to the brain are altered in those that have degenerative diseases of the retina. Here, we will examine the cause of these cellular changes in an animal model and seek to prevent the loss of output neurons. This information is crucial for the development of treatments that seeks to restore vision.
The retina lines the back of the eye and sends multiple movies of the visual world to the brain. This project aims to investigate how these multiple information channels are created. Descriptions of the basic pattern of wiring in the healthy retina will help clinical researchers to understand the disruptions that occur in visual disease. The precision of normal retinal wiring also delineates the precision required to restore normal function to a diseased or degenerating eye.
