Handbook of Retinal Screening in Diabetes

Handbook of Retinal Screening in Diabetes

by Roy Taylor




This book, a successor to the highly popular Practical Guide to Polaroid Retinal Photography, describes the essential components of a retinopathy screening programme, including the criteria for referral to an ophthalmologist, drawing upon the experience of the Newcastle system over the last two decades and the National Screening Committee Report upon Eye screening. It is fully illustrated, featuring a new set of 50 digital colour photographs, showing the normal retina and problems associated with diabetes, with explanatory text.

"[T]he first concise textbook on retinal screening... well structured and written... provide[s] excellent background reading to those entering the new profession of retinal screening." PRACTICAL DIABETES INTERNATIONAL
