In a questionnaire survey we determined the prevalence of visual symptoms and eye strain factors in a group of chronic headache sufferers as compared with age- and sex-matched controls. The visual symptoms studied were those not specific for headache, i.e., sensitivity to light and blurred vision. Sensitivity to light in the absence of headache was reported by 27.8% of controls and 44.7% of headache sufferers (p less than 0.05). The latter figure increased to 71.3% when headache was actually present (p less than 0.001). Blurred vision occurred in 13.5% of controls and 7.4% of headache sufferers (not significant). In the presence of headache, the latter figure increased to 44.7% (p less than 0.01). Of the eye strain factors studied, bright light was reported to precipitate headache in 29.3% and to aggravate it in 73.4%. For reading, these figures were 16.0% and 55.3%, respectively; for working at the computer screen, 14.5% and 31.3%; and for watching television, 6.4% and 27.7%. We conclude that visual symptoms are more common in chronic headache and eye strain factors more important than is generally recognized.
在一项问卷调查中，我们确定了一组慢性头痛患者与年龄和性别匹配的对照组相比，视觉症状和眼疲劳因素的患病率。所研究的视觉症状是那些并非头痛特有的症状，即对光敏感和视力模糊。无头痛时，27.8%的对照组和44.7%的头痛患者报告有对光敏感（p<0.05）。当实际出现头痛时，后一数字增至71.3%（p<0.001）。视力模糊在13.5%的对照组和7.4%的头痛患者中出现（无统计学意义）。出现头痛时，后一数字增至44.7%（p<0.01）。在所研究的眼疲劳因素中，据报告强光可诱发29.3%的头痛并使73.4%的头痛加重。对于阅读，这些数字分别为16.0%和55.3%；对于在电脑屏幕前工作，分别为14.5%和31.3%；对于看电视，分别为6.4%和27.7%。我们得出结论，视觉症状在慢性头痛中更为常见，且眼疲劳因素比一般认为的更为重要。
