목적 : To evaluate the effect of cataract surgery on the slow and fast components of
visual field decay in a group of patients with glaucoma.
방법 : Retrospective, interventional, longitudinal study.
Eighty-five eyes of 68 patients with open-angle glaucoma who had cataract extraction were
included. All patients had 5 or more reliable visual field measurements before and after
surgery. A pointwise exponential regression was used to perform trend analysis on
thresholds at visual field test locations before and after cataract surgery. The test locations
were ranked according to the decay rate and were partitioned into slow and fast groups.
결과 : The mean (SD) mean deviation was −5.5 (5.1) dB before cataract surgery and −5.0
(4.9) dB after cataract surgery (P = .002). The mean (SD) Visual Field Index was 86.4%
(13.5%) before cataract surgery and 86.6%(13.3%) after cataract surgery (P = .30). The mean
(SD) slow component rate decreased from 0.48%(0.73%) per year before surgery to 0.26%
(0.42%) per year after surgery (P = .04). No statistically significant difference was identified
in the fast component mean (SD) rate per year before surgery (3.37%[4.05%]) vs per year
after surgery (3.46%[3.56%]) (P = .29).
결론 : Cataract progression seems to be the main determinant for
the slow visual field rate component and does not change the fast visual field rate
component.We conclude that the method used can help reduce the confounding effects of
cataract progression and cataract extraction on measured perimetric progression in
glaucoma.
