PURPOSE
To determine the characteristics of visual field defects in acute primary angle-closure glaucoma and identify risk factors affecting such field defects. METHODS: Automated static perimetry was performed in 60 patients at least 3 months after remission of the acute attack. Glaucomatous visual field defects were defined as 3 or more contiguous points on the pattern deviation plot depressed at p<5% level and one point depressed at a p<1% level. RESULTS: Visual field defects were seen in 40 (67%) of 60 patients. The upper nasal area was most frequently and more severely affected. Only 2 cases (5%) presented a localized type defect. The multiple logistic regression showed that sex (odds ratio=23.1, 95% confidence interval [CI]=3.2 ~ 168.6, p=0.002) and vertical cup to disc ratio (odds ratio=5.5, 95% CI=1.2 ~ 24.8, p=0.03) were significant risk factors for visual field defects. Duration of the acute attack was a marginally significant risk factor (odds ratio=5.2, 95% CI=0.8 ~ 31.8, p=0.08). CONCLUSIONS: The upper nasal visual field was affected most frequently and more severely. The localized defect was rare. Women and the large vertical cup to disc ratio were associated with increased risk for visual field defects. A longer duration of the acute attack seems to more likely develop visual field damage. |
