Central corneal thickness measurements in nonarteritic anterior ischemic optic neuropathy patients: A controlled study

Purpose. to measure central corneal thickness (cct) in patients with history of nonarteritic anterior ischemic optic neuropathy (naion). patients and methods. patients older than 40 years with a history of naion (group 1) were prospectively evaluated including full eye examination and central corneal thickness (cct) pachymetry. patients with a history of intraocular surgery,corneal disease,glaucoma,and contact lens wear were excluded. measurements were also performed in a gender and age matched control group (group 2). results. thirty-one eyes of 31 naion patients in group 1 were included and 30 eyes of 30 participants in group 2. there were 15 men in group 1 and 9 in group 2 p = 0.141,and mean age of the patients was 59 ± 10 years in group 1 versus 61 ± 11 years in group 2 p = 0.708. mean cct was 539 ± 30 microns in group 1 and 550 ± 33 microns in group 2 p = 0.155. conclusion. patients with naion have no special characteristic of cct in contrast to the crowded optic disc known to be a significant anatomic risk factor for naion. more studies should be carried out to investigate cct and other structure related elements in naion patients. © 2014 haneen jabaly-habib et al.
