Abstract

Abstract: : Purpose:To investigate the effect of cataract surgery on the results of FDT perimetry. Methods:Subjects who were scheduled to undergo cataract surgery were prospectively identifed. Subjects underwent FDT perimetry in both eyes using the C-20 full threshold algorithm. Visual field testing was performed within one month before, and within three months after cataract surgery. The eye that did not undergo surgery served as a control. Results:49 eyes of 49 patients were included in this study. A mean improvement in mean deviation (MD) of 4.15 dB (P<.0001) was observed in the eyes that underwent cataract surgery. A mean improvement in MD of 1.33 dB (P=.13) was observed in the control eyes. The mean improvement in MD attributable to cataract surgery (improvement in surgical eye - improvement in control eye) was 2.82 dB (P<.008). Conclusion:Cataract removal does result in an improvement in the MD using FDT perimetry.
