The cornea is also photographed whenever the CLEK Photography
Reading Center directs the CLEK Clinic to rephotograph the cornea due to poor
photograph quality.
The fluorescein pattern photography protocol is in Chapter 10, and the
corneal photography protocol is found in Chapter 11 of this Operations Manual.
Both protocols are also in the CLEK Photography Reading Center Operations
Manual.
14.3 CLEK Photography Reading Center Procedures
The CLEK Photography Reading Center Coordinator purchases Kodak
Ektachrome ASA 100 film and stores it in a secure cabinet. Prior to the beginning
of the CLEK Study and at six-month intervals thereafter, or as necessary, the
CLEK Photography Reading Center Coordinator sends rolls of film to each of the
CLEK Clinics. Only film from the CPRC may be used. CPRC film is reserved for
CLEK Study patients. The CLEK Photography Reading Center Coordinator
maintains a log of this activity.
The CLEK Photography Reading Center Coordinator receives film from
the CLEK Clinic, logs the receipt of the film onto the film log, and delivers it to
the processing laboratory within two working days.
The CPRC Director or his designated reader determines if the slides are of
adequate quality to be graded. The CLEK Photography Reading Center
Coordinator or Slide Labeling Technician labels the slides, the CPRC Coordinator
arranges the slides in carousel slide projector trays as directed in the CPRC
Operations Manual. The Coordinator informs a CPRC Reader that the slides are
ready to be read.
The CPRC Readers read the slides, recording slide quality and grading
outcomes on the computer screen. The Reader reads photographs without
knowledge of the patient, condition, Clinic, etc. After determining that all the
data are complete and entered accurately, the Reader stores the results on the
computer. The Reader may also place notes in the file with suggestions to
improve photography that are conveyed to the Clinic by the CPRC Director.
14.4 Repeat Photography
In the event of poor quality fluorescein or corneal photographs, repeat
photography is necessary.
