Abstract

To access the effects of trabeculectomy or medical treatment on automated visual field progression in glaucoma, a retrospective automated visual field data were obtained for those who underwent six Humphrey C30-2 field tests over at least 4 years. The first field data was excluded. Linear regression was performed with respect to mean deviation[MD], corrected pattern standard deviation[CPSD], and mean thresholds of Glaucoma Hemifield test[GHT]. Subjects were classified as progressive or stable based on the slope and statistical significance. There were 19 persons[25eyes]in surgery group and 16 persons [27eyes]in medication group. The levels of IOP in all subjects were maintained under 21 mms of mercury during all follow-up periods. There was no difference in mean postoperative IOP between both groups[p>0.05]. There were no significant dif-ferences in numbers of aggravation respect to MD, CPSD, and GHT between two groups of surgery and medication[p>0.01]. There was no differnce in the visual field outcome between two groups of surgery and medication with same level of IOP.
