The serum level of creatine kinase is an indicator of the functional status of muscle tissue and various extensively in both pathological and physiological circumstances. An increase in creatine kinase is also characterized as a guide of cellular necrosis and tissue damage following acute and chronic muscle injuries. Changes in serum levels of creatine kinase are also found in normal subjects and in athletes after exhausting exercises. We present the case report of young highly-trained swimmer who was admitted to the hospital because of transient blurred vision, visual field defects of his left eye, accompanied by headache and nausea. Intracranial expansive process was excluded, ophthalmologic pathology also. Transient hyperCKemia was found without myoglobinuria, not linked to any injury, no muscle disease was detected and there was no cardiomyopathy. We can explain transient blurred vision, visual field defects exclusively on one eye following by headache and nausea by excessive exercise, profound fatigue and extremely high desire for success in school and swimming competitions. A follow up of sport's medicine physician, psychologist and balanced nutrition while continue with undertaking physical activity was recommended for this young swimmer. In case of recurrence, the muscle pathology detection and genetic testing should be considered. |
