Central macular thickness (CMT) modification during the follow-up visits measured with spectral domain optical coherence tomography. At baseline, CMT was 497 μm (a); one week after 3 posterior subtenon injections of natural leucocytic interferon-α 2a. CMT decreased to 237 μm (b); after 1 month (c), 3 months (d) and 1 year (e) CMT was 215, 255 and 299 μm, respectively.
