title: Central corneal thickness measurements in nonarteritic anterior ischemic optic neuropathy patients: a controlled study.
abstract: 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.
