Predicting the genetic risk of glaucoma

Little is known about the genetics of glaucoma and a more thorough understanding of the biological pathways involved may lead to better risk prediction and treatment options.

Better identification of those people at high risk of glaucoma, through genetic screening, would result in an overall reduction of preventable blindness by identifying those at risk and treating the condition before serious sight loss has occurred.

Congenital glaucoma

A number of genetic variations have been identified - some by our researchers - that are associated with congenital forms of glaucoma. Further identification of these genetic variants will help in early detection and treatment of congenital glaucoma and counselling families about the risk of recurrence and reproductive options.

Glaucoma search filter

Evidence Based Eye Search

Glaucoma is the second most prevalent cause of blindness worldwide. The Flinders Centre for Ophthalmology, Eye and Vision Research engaged Flinders Filters to develop a Glaucoma Search Filter, supporting evidence based research and expanding the knowledge base.

Glaucoma topic searches

These topic searches have been combined with the glaucoma search filter and are focused on areas of interest to glaucoma.
