Abstract Details


To evaluate rate of progression (RoP) in treated patients with primary open angle glaucoma (POAG).


Dept Ophthalmology, Medical University, Plovdiv, Bulgaria


Fifty six eyes of 30 glaucoma patients (11 male and 19 female, with mean age in the beginning of the follow up 58.9 �Â�± 9.9 years) were enrolled in this study. Using Humphrey field analyzer (program 30-2) the visual field progression rates were calculated as slopes of mean deviation (MD) over time. The mean follow up period was 7.31 �Â�± 2.00 years. All statistical analyses were performed using SPSS v. 22.0.


Mean MD at the start of the study was -10.35�Â�±8.72dB and MD under -15 dB was observed in 16 eyes (28.6%). Negative slope of MD values showed 30 eyes (55,4%) of 21 patients (70%). There was a positive tail of no progressing of all eyes (44.6%). The mean value of RoP (decibels per year) with negative slope was -0.64�Â�±0.54 dB (ranging from -0.05 to -2.33dB. RoP was independent of the baseline MD (p=0.624). There was no correlation between RoP and age and between baseline MD and age. Slow progression (RoP�â�‰�¤-0.3 dB/year) was found in 11 eyes (20%).


There was a wide range of progression rates in treated patients with primary open angle glaucoma. We observed no progression and slow progression of disease in 64.6% of cases.
