Film Fluorescein AngiographyFluorescein angiography may be captured on film if digital facilities are not available.• The recommended film is Kodak T-Max or Il<strong>for</strong>d 400 speed film.• The film may be processed by clinic staff or at a local processing laboratory.• The use of Kodak D-11, or similar developer, is recommended.• Any processing procedure that produces good quality negatives may be used.• Proper care should be taken to adequately fix the film to insure archivalstability.The timing <strong>for</strong> analogue fluorescein procedures is the same as <strong>for</strong> digital.Although it is customary to take the left member of a stereo pair first, when shootingwith film you must take the right side first.5. Mounting and Labelling of colour slidesAfter the slides are returned from the processing lab they must be sorted into theirstereo sets and each correctly labelled, with the centre and patient IDs. The labelledslides are then placed into transparent plastic sheets in the correct order <strong>for</strong> eacheye (see diagram below). Use one sheet <strong>for</strong> each eye. An identification label iscompleted and attached to the front of each plastic sheet.• The original negatives are cut into strips of six im<strong>age</strong>s per strip and are placedin a transparent plastic sheet with six strips per sheet (see diagram below).• A p<strong>age</strong> identification label is attached to each p<strong>age</strong> of negatives.• When cutting the film into strips, the photographer should take care not toseparate the members of a stereo pair.• Clinical centres should retain a copy of the angiogram by making a duplicateof the original negatives.As <strong>for</strong> digital files, films must include the following in<strong>for</strong>mation about each patient:• Centre ID• Hospital number• Date of birth• Date of angiogram© Queen’s Printer and Controller of HMSO 2012.
