Age and the van Herick ratio in a Chinese population

We derived estimates of the van Herick ratio or grading in a retrospective study using a Chinese clinical population. We found that the van Herick ratio decreased with age and increased with higher degrees of myopia. A lower van Herick ratio was found to be associated with higher intraocular pressure. There are significantly more patients with lower van Herick ratios or grades in our population than in populations described by others.
