The authors aimed at investigating ophthalmological changes high altitude and correlating this with blood oxidation/antioxidation parameters.There were 40 volunteers who participated in the study. Initial examinations performed 3543 ft (1080 m) repeated on following day after participants climbed to an of 9186 (2800 Mt. Erciyes, Turkey. Venous samples taken both altitudes evaluate total oxidative system (TOS) antioxidative (TAS) levels.IOP-right eyes was 13.23 +/- 0.43 mmHg significantly...
