The purpose of this study was to identify the differences in corneal parameters between medically treated NTG and POAG subjects.
Department of Ophthalmology, Queen Mary Hospital / The University of Hong Kong
This cross-sectional study from September 2011 to September 2012 included consecutive subjects with POAG and NTG who were receiving topical anti-glaucoma medications at the time of the study. Subjects were excluded if they had pre-existing corneal pathology or scars and previous glaucoma lasers. The following parameters were compared between the NTG and POAG groups: endothelial cell count, central corneal thickness (CCT), spherical equivalent, presenting and current intraocular pressure (IOP), number and type of anti-glaucoma medication, retinal nerve fibre layer (RNFL) thickness, Visual Field Index, visual acuity, and phakic status
Both the NTG and POAG groups had comparable baseline characteristics, post-treatment IOP, and glaucoma severity. The endothelial cell count was significantly lower in the NTG versus the POAG group (2380±315.4 cells/mm2 versus 2530±320.4 cells/mm2, p = 0.039). There were no significant differences in the spherical equivalent or central corneal thickness between the NTG and POAG groups.
A significantly lower corneal endothelial cell count was found in NTG compared to POAG. FINANCIAL INTEREST: NONE
