VISUAL EVOKED POTENTIALS IN COPD
Monika Kamra, Dr. Sonia Kochhar
Abstract :
Aims and objectives: To evaluate the effect of COPD on Visual Evoked Potential wave latencies and amplitude.
Methods and Material: The study was conducted in the department of Physiology, MMIMSR, MMU, Mullana (Ambala). The study comprised of
100 subjects divided in two groups. Group–1 contains 50 normal healthy subjects. Group–2 contains 50 COPD patients both males and females.The
equipment used was Allengers Scorpio EMG EP NCS system provided by Allengers Medical system Limited, Chandigarh. VEP was evaluated by
voltage changes generated following application of pattern reversal visual stimulus to the visual system. Pulmonary function test was performed to
all the subjects. The parameters assessed were FVC, FEV1 and FEV1/FVC ratio by using computerized, Helios software. Unpaired T–test was used
to evaluate the statistical value.
Results and conclusions: In our study VEP wave latencies i.e N75 wave, P100 wave, N145 wave latencies and P100 wave amplitude in COPD
patients were prolonged highly significantally in both eyes with P value less than .0001 and less than .03 respectively.
