The Sight Loss and Vision Priority Setting Partnership
FORM A: LONG LIST OF UNCERTAINTIES FOR GLAUCOMA AND RELATED SYNDROMES
The uncertainties listed on this form have been gathered from a survey and consultation with people affected by sight loss, their partners, relatives and carers and eye health professionals. The survey submissions relating to glaucoma and related syndromes were checked and formatted into questions. Where there were duplicates, or very similar submissions, these were combined. The questions below are defined as uncertain because they cannot be answered by an up-to-date systematic review of relevant research evidence. You are being asked to choose and rank 10 of the uncertainties below. You may wish to choose 10 from a single category or choose 10 from across a number of different categories. Please see Form B for instructions on this prioritisation exercise.
