Aim
The study was designed to evaluate if there is any inter-observer variability in the measurement of corneal ulcers between different graders.
Methods
A prospective, observational, blinded study including 50 patients, who were examined by 4 graders [1 cornea consultant (grader 1), 2 cornea fellows (grader 2 and 3) and 1 senior mid-level ophthalmic personnel (grader 4)]. Epithelial defect (ED), stromal infiltrate (SI), depth of ulcer, hypopyon size and location of ulcer were noted.
Results
Inter-class correlation (ICC) for ED height was 0.958, for ED width was 0.927, for SI height was 0.962, for SI width was 0.940 and for hypopyon was 0.988. ED size was significantly different from 0.5 mm for 2 out of 12 grader pairs (Width: Grader 2 vs 3, Grader 2 vs 4) and SI was significantly different from 0.5 mm for 2 out of 12 grader pairs (Width: Grader 1 vs 3, Grader 2 vs 3).
Conclusion
There was good reliability between the four graders, with significant differences for few measurements.
