Purpose:
|
To find the best condition of the pupil for tele-screening of DR in eyes with dark irides.
|
|
Methods:
|
45⁰ fundus photographs of diabetic patients taken with a non-mydriatic fundus camera in three conditions of pupil: non-mydriatic, 10 minutes after one drop of mydriatic, and fully dilated, and from two different locations: macula centered and disc centered were graded by 2 vitreoretinal specialists as good, poor and ungradeable according to defined criteria using predesigned software.
|
|
Results:
|
1768 images from 295 patients were included. There were more ungradeable images (38.1% and 50.3% for raters no 1 & 2 respectively) in the non-mydriatic state than partially (4.6% and 11.5 %) or fully dilated images (15.4% and 10.0 %) (p<0.001 for both reviewers). Partially and fully dilated images were similar in this regard (p=0.56 and 0.54). Macula centered images had less ungradeable images than disc centered photographs (14.9% and 16.9% vs. 16.0 % and 31.2% for reviewer no 1 & 2 respectively). Test–retest reliability (repeatability) was 92.5% and 74.3%. The inter-rater agreement was moderate (Kappa=0.50).
|
|
Conclusion:
|
Instillation of one drop of mydriatic 10 minutes before photography is indicated in dark eyes and considerably lowers the percentage of ungradeable images for tele-screening of DR.
