영문 초록

Purpose: To investigate the changes of electroretinogram (ERG) at baseline and during the first 3 injections of intravitreal bevacizumab in central retinal vein occlusion (CRVO) patients. Methods: Thirteen eyes of 13 CRVO patients who received 3 injections of intravitreal bevacizumab at 6-week intervals and who could be examined for visual acuity, optical coherence tomography and ERG at 4 weeks after each injection were included in the present study. In addition, the ERG results of the unaffected fellow eyes group at 4 weeks after each injection were compared with the CRVO eyes group. Results: Amplitudes of rod b wave, a and b waves of maximal combined response and cone response, oscillatory potentials and 30-Hz flicker significantly decreased in the CRVO eyes group than the fellow eyes group at 4 weeks after each injection (p < 0.001). After injection, amplitudes of all the above-mentioned ERG parameters gradually increased during the 1st and the 2nd injection (p < 0.001). However, there was no significant difference at 4 weeks after the 2nd and 3rd injections (p > 0.05). Conclusions: After intravitreal bevacizumab injection, macular functions significantly improved and amplitudes of all ERG parameters gradually increased in CRVO patients.
