Change in the mean deviation value in both eyes after 8 years of treatment. The central visual field was assessed using the mean deviation (MD) value obtained using the Humphrey field analyser with the 10–2 SITA standard program. The MD values declined similarly in both eyes. The slope of the MD during the 8 years of treatment was − 0.68 dB/year and − 0.32 dB/year in the right eye and left eye, respectively. The results from the first examination for the right eye appear to be an outlier
