Retina Service Acquires ERG machine for clinical practice, first and only in Worcester area

Date Posted: Monday, September 12, 2016

The Department of Ophthalmology & Visual Sciences has officially acquired ERG (electroretinogram) machine. The machine will be utilized in the Retina service and will be the first and only machine in the Worcester area. The ERG test can aid Retina specialist in detecting electrical activity and abnormal function of the retina.

The ERG machine will be a valuable asset in the clinic, consisting of two components Multifocal and  Full field Tests. The ERG provides trivial diagnostic information in a range of retinal diseases. It can be also used for monitoring toxicity of various drugs, one example is (Plaquenil). We believe that the  ERG will be of great benefit and will provide enhanced care for our patients in the community.
