CoDEx: Computerised Diagnostic Expertise


CoDEx is a free online computerised diagnosis system designed to help non-ophthalmologist clinicians (GPs, emergency physicians, optometrists) form a relevant differential diagnosis in cases of acutely red eyes. It also contains information about each condition and is illustrated for ease of use. It relies mainly on directed history taking and artificial intellitence analysis of the user's answers. The system was developed in 2014 by Dr Ehud Zamir at the Centre for Eye Research Australia, using a grant from Melbourne's Lord Mayor Charitable Foundation. Dr Zamir's lecture about this system can be accessed here.

Learn how to measure the anterior chamber depth with a digital camera or your smartphone. The method was invented by A/Prof Ehud Zamir and recently published in TVST by a team of ophthalmologists from the University of Melbourne . 

Relevant for GPs and other non ophthalmologists who assess patients for possible
