Abstract

|
Purpose: To compare the Hong`s grading method, utilized for slit-lamp grading of the mid-peripheral angle, with other conventional grading methods. Actual angle was measured by ultrasound biomicroscopy (UBM) for comparison.
Methods: Fifteen eyes with narrow angles and eighteen eyes with wide angles were studied. The average age of thirty-three subjects was 46.8±19.2, and the male to female ratio was 1:3.7. The mid-peripheral angle was graded by Hong`s, van Herick`s and Spaeth`s grading system. The actual anterior chamber angle was evaluated by UBM and the correlation between each grading system and actual angle was investigated.
Results: The results from the Hong`s grading (r=0.802, R2=0.643, p<0.01), Spaeth`s grading (r=0.728, R2=0.530, p<0.01) and van Herick`s grading (r=0.618, R2=0.382, p<0.01) methods correlated significantly with the actual angles.
Conclusions: The Hong`s grading method was an easy and effective tool to evaluate anterior chamber angle. In addition, the results of the Hong`s grading method were closer to the actual angle than the other methods. J Korean Ophthalmol Soc 48(3):399-404, 2007
