It is increasingly recognised that many adult eye diseases such as cataract, glaucoma and diabetes are modified byu a person's genetic constitution. There are some aspects of mot genetic eye diseases which can be treated, but as yet treatment to put right the genetic problem itself is not available for thee conditions. There is a great deal of research being done into genetic disorders, and it is reasonable to expect advances in treatment in future years. The ophthalmologist's role in genetic eye disease is to make a specific diagnosis, institute any necessary treatment and register the patient as visually handicapped if appropriate. Once the ophthalmologist has made a diagnosis, the geneticist can then provide an estimate of the risk of future children being affected by the disease.
Prenatal testing is available for some genetic eye conditions.
Some units employ liaison nurses to provide ongoing support and counselling. Genetic eye diseases affect whole families, and the psychological needs of unaffected individuals should not be ignored as there are often significant feelings of guilt and loss.
