Interobserver agreement in scoring of dual fluorescein and ICG inflammatory angiographic signs for the grading of posterior segment inflammation.

PURPOSE

To test interobserver agreement in the fluorescein/indocyanine green angiography (FA/ICGA) scoring system for uveitis.

METHODS

Four observers scored 32 dual FA/ICGAs. Spearman rank correlation was used to analyze correlation between pairs of observers in scores assigned to angiographic signs. Kappa statistics were used to test agreement between pairs of observers in comparative total FA and ICGA scores.

RESULTS

The authors found a significant correlation between pairs of observers in scores assigned to all FA signs and all except one ICGA sign. The only discordant sign was early stromal vessel hyperfluorescence on ICGA. There was a moderate to substantial agreement between pairs of observers in comparative FA/ICGA total scores.

CONCLUSIONS

The level of agreement between uveitis specialists in scoring of dual FA/ICGA indicates that the scoring system tested in this study will be useful for clinical studies of uveitis. Increased experience with this system may further improve its reproducibility.
