Exchange contributions wanted

The Community Eye Health Journal would like to invite readers to submit short articles (500 words) for the Exchange section of the journal. For Issue 64 (December 2007) and Issue 65 (March 2008) we are particularly interested in experiences related to advocacy and cataract complications, respectively.


Sue Stevens will be retiring and leaving the International Centre for Eye Health (ICEH) and the Community Eye Health Journal at the end of July. She has been here since 1993, giving professional nursing input to the journal and providing educational information and resource services to eye health workers all over the world. Sue will be sorely missed and we wish her well in her future endeavours. For information please contact Jenni Sandford: [email protected]


Many thanks to the late Dr Hans Hirsch and his family for their support to the Community Eye Health Journal over the next three years. Dr Hirsch and his wife Gertrude had a strong interest in helping those who are blind, both through education and through clinical interventions.
