Effects of Misalignments in the Retinal Nerve Fiber Layer Thickness Measurements with Spectral Domain Optical Coherence Tomography

Table 1

Demographic characteristics of the eyes with complete or partial misalignments included in the study.

	Eyes ()
Age (years; mean ± SD)	49.1 (±13.5)
Gender (male [%] : female [%])	20 [36%]/36 [64%]
Race (Caucasian [%] : African-American [%])	48 [86%]/8 [14%]
Eye (right [%]; left [%])	49 [87%]/7 [13%]
Mean visual acuity (log MAR; mean ± SD)	0.04 (±0.096)
Health [%]; glaucoma [%]	27 [48%]/29 [52%]
Location of the MA (1/2/3/4)	14/16/22/4
Mean spherical equivalent (diopters; mean ± SD)	0.25 (±1.18)
Intraocular pressure (mmHg; mean ± SD)	14.0 (±2.6)
Medications (mean ± SD)	1.0 (±1.3)
MD (dB; mean ± SD)	−3.2 (±5.4)
PSD (dB; mean ± SD)	2.7 (±2.9)

SD = standard deviation; MA = misalignment; MD = mean deviation; dB = decibel; PSD = pattern standard deviation.
