Abstract (Summary)
ABSTRACT Purpose: To analyze the visual field in mild brain trauma (MBT) Methods: 36 patients with MBT (GCS among 13-15, without pathology in Computer Tomography, loss of consciousness less than 30 minutes and amnesia less than 24 hours), were examined using the TOP strategy three times (twice a week after the traumatism and once three months later). The results compared with 36 normal controls examined twice. Results: The MD and LV square root (sLV) were significantly higher in the first two examinations (Right eye MD = 3.197 and 3.675 dB, sLV = 2.858 and 2.872 dB; Left eye: MD = 2.994 and 4.130 dB, sLV = 2.664 and 2.986 dB) than in the third one (Right eye: MD = 0.630 dB, sLV = 1.797 dB, Left eye: MD = 1.278 dB, sLV = 1.967 dB) (p<0.01). There were not differences between the MD and sLV of the third exam of the pathological group and the two examinations of the control group (MD = 0.6 and 0.7dB, sLV = 1.9 and 1.8dB) (p>0.05), indicating a complete recovery. The test-retest threshold fluctuation of the pathological group (3.117 +/- 1.101 dB) showed a highly significant difference with regard to the control group (2.909 +/- 1.061 dB) (p<0.01). 28.9% points showed relative scotomas in the first two examinations in MBT group. 52.1% were reproduced in the same position in both examinations and 58.62% coincided in homonimus position. Conclusion: A diffuse and transitory deterioration of the visual sensitivity, with some certain specific topographical preferences, was detected in these patients
