中文摘要 | 作者以美國費城威爾斯眼科醫院青光眼科長期追�j之青光眼患者為對象,分析視 野缺損與患者自覺之生活不便性之相關程度。在研究過程中利用一特別設計之問卷以評估患 者之自覺之生活不便性( Vision-associated Limitations in daily activities, VALDA ), 問卷所獲得之結果則與患者之視野變化( Humphrey 24-2 program )相比較,結果發 現自覺之生活有不便性的青光眼患者中,大多數的人最感到有問題的是夜間駕車,且除了視 野變化因素之外,年齡與視力亦是決定患者是否感覺有生活不便之重要因素。 另外研究中亦發現, 兩眼視力皆大於 0.5 的青光眼患者之中,患者自覺的生活不便性與視 野指數的平均偏差值( MD )有較大的相關性( P<0.01 ), 而與型態標準偏差值( PSD )較無關( P<0.02 ),至於視野缺損之型式則與患者自覺的生活不便性並無一定之關聯, 惟若患者有雙眼視野中心點缺損或下方弓狀缺損合併殘存中心點視野者, 則大多數患者( 89% )會覺得近距離工作有困難。 |
英文摘要 | Purpose: To explore the relationship between visual field loss and the perception of visual disabilities in patients with glaucoma. Methods: Aquestionnaire designed to identify vision-associated limitations in daily activities (VALDA) was applied to 231 patients with glaucoma who had reliable computerized visual field examination with the Humphrey 24-2 pngram. Visual field loss was quantitatively ("mean deviation" (MD) and "pattern standard deviation" (PSD) and qualitatively (pattern of visual field defect) assessed. The relationship between the presence of VALDA and visual field defects was evaluated. Results: The most frequently reported VALDA was limitation in night driving. Age and visual acuity (VA) were related to the perception of VALDA. The visual field index MD in cases with VA better than 20/40 in both eyes correlated well to the perception of VALDA (P<0.01), but PSD did not (P>0.2). Among the patterns of visual field loss, patients with bilateral fixation involvement, or the presence of inferior arcuate scotomas or central island defects in both eyes were frequently associated with near vision problems (89%). No other combination of visual field patterns was found to correlate with a specific limitation. Conclusion: The presence of vision-associated limitations in daily activities in patienst with good visual acuity was correlated with the MD index but not to the PSD. The perception of VALDA does not necessarily correlate with the pattern of visual field loss. |
