Abstract Details

Purpose:

To assess the rates of visual field progression in exfoliative open angle glaucoma followed more than 5 years with standard automated perimetry (SAP).

Setting:

Department of Ophthalmology, Medical University Plovdiv, Bulgaria

Methods:

Sixty eyes of 39 treated patients with exfoliative glaucoma (14 male and 25 female, mean age at the beginning 67.2 ± 7.2 years) were enrolled in this study. The mean follow up period was 7.31 ± 2.00 years. In 18 patients with unilateral glaucoma the affected eye was selected and in 21 patients with bilateral glaucoma both eyes were analysed. Using Humphrey field analyzer (programme 30-2) the visual field progression rates were calculated as slopes of mean deviation (MD) over time. All statistical analyses were performed using SPSS v. 22.0.

Results:

The mean rate of progression (RоP) in the study group was - 0,51 ± 0.85 dB/year (decibels per year) ranging from +1.9 to - 3.08 dB. Mean MD at the start of the series was -13.54±10.19 dB. Negative slope of MD values was observed in 76.7% of the eyes. RoP was independent of the baseline MD (p=0.648). Slow progression (RoP ≤ - 0.3 dB/year) was found in 13 eyes (21.7%) and moderate to fast progression – in 29 eyes (48.3%). Only 3.3% of the eyes progressed at rates worse than – 2.5 dB/year. There was a positive tail of no progressing of all eyes.

Conclusions:

There was a wide range of progression rates in treated patients with exfoliative glaucoma. We observed fast progression with RoP < 1dB/year in 25% of the affected eyes.
