The Retina Department evolved from the Research Department, and was established as a separate entity in 1962. It now has a staff of seven. The function of the department is to carry out clinical electrophysiological diagnostic tests on pre and post-operative cases suffering from a variety of conditions, and on certain genetic conditions: e.g. retinitis pigmentosa. It is also involved in plotting visual fields, carrying out colour vision analysis and dark adaptation.

In 1972 less than 1,000 patients were seen: by 1982 the number had increased to almost 3,500, more than 550 of these having come from outside the Region

This has been partly due to the advances in technology as a wide range of tests are now available.
