ABSTRACT
OBJECTIVE: To study age-related effects on the retinal nerve fiber layer thickness (RNFLT). METHODS: 75 eyes of 75 normal volunteers were recruited. Their ages ranged from 20 to 66 years. They were divided into five age groups of 15 subjects each. We measured each subject's RNFLT using scanning laser polarimeter. The mean RNFLT within the 1.5 disc diameter ring around the optic nerve papilla and its four quadrants (superior, temporal, inferior and nasal) was calculated. RESULTS: The mean +/- SD of RNFLT was 76.4 +/- 7.50 microm, 71.5 +/- 7.3 microm, 72.1 +/- 3.9 microm, 66.7 +/- 7.2 microm and 67.4 +/- 8.5 microm, respectively. CONCLUSIONS: The RNFLT decreases with aging in the normal healthy eye.
