Evaluation of the optic nerve head and peripapillary retinal nerve fiber layer changes in warplanes pilots

The pilots of aircraft was predispose to various physical forces, such as hypoxia, acceleration and vibration during flight. One of the most important pressures was G force. The changes in intraocular pressure and blood supply of the eye during flight in chronic, long-term period can cause changes in the optic nerve head and retinal nerve fiber layer thickness. To determine changes in the optic nerve head and peripapillary retinal nerve fiber layer thickness in combat pilots 50 cases of military aircraft pilots complete ophthalmic examination was performed and demographic and clinical data were recorded. All samples were then examined using OCT peripapillary retinal nerve fiber layer thickness. To study the characteristics of the optic nerve head imaging was performed using HRT. The final analysis was performed on the data obtained and recorded. In this pilot study, with a mean age of 50 13/4 ± 7/43 years participated. Average years of experience of the pilots were flying combat aircraft, 46/2 ± 84/9 years. In a comparison of optic nerve head parameters measured by OCT included disc, cup, rim, cup and rim volume, cup-to-disc ratio and cup depth, there was no significant difference with normal individuals. In this study, the average RNFL thickness around the optic nerve, which was equivalent to 102.83 ± 9.76 mm, compared with the normal population is 106.59 ± 12.82, is lower, but the difference is not significant. (P = 0.45). There are no any significant side effects in optic nerve head and pri papillary retinal nerve fiber layer thickness.
