【Abstract】 Serum zinc of 50 patients with eye-ball contusion was determined from Nov. 1991 to Aug. 1992. It was found that 36 patients (72% of the total) showed abnormality in their zinc values (140.9±43.4μg/dl). Changes in ocular fundus occurred in 75% of the patients. It wasalso found that when optic nerves and retinae were contused, the zinc value increased. Lower zinc value interferes with the metabolism of the retinal rod and cone cells, resulting in lowered eye-sight, and affects the synthesis of visual pigment and the metabolism of the pigment epithelium, leading to retinal pigment disturbance after contusion of eye-ball更多还原
