Central corneal thickness of normal-tension glaucoma and non-glaucoma populations in ethnic Chinese.

Background: The variations in central corneal thickness can influence intraocular pressure measurement. The aim of our study was to determine whether there is a difference in the central corneal thickness between normal-tension glaucoma (NTG) and non-glaucoma populations.

Methods: This prospective study included 33 consecutive patients with NTG and 33 age- and gender-matched healthy subjects as control subjects.
