聚合不足患者的閱讀表現及頭痛症狀

聚合不足是一種眼球在看近時，內轉的能力不足的現象。


患者在人群中所佔比例似乎被低估

此研究中，20~49歲被評估為聚合不足的患者中，有百分之四十九的患者，抱怨近方工作時有視力模糊及頭痛現象。而其他的研究中年輕成人約5個中有3個(60%)。
這並不是新聞，因為Kratka 在1956就發現診斷的500位患者中，25%指出有聚合不足。

Forty-nine percent of the patients aged 20-49 years in this study who were evaluated presented with convergence insufficiency. Other studies have found that roughly 3 in 5 (60.4%) of young adult patients complaining of blurring of vision at near work and headache suffered from convergence insufficiency (Dragomir M, Trus L, Chirila D, Stinger C. Orthoptic treatment efficiency in convergence insufficiency treatment.Oftalmologia 2001, 53(3): 66-69.). This is not news since  Kratka found that 25% of a sample of 500 patients had exam findings indicative of convergence insufficiency way back in 1956 (Kratka, Z and Kratka, W. H; Convergence insufficiency: its frequency and importance. Am Orthoptic J 1956; 6: 72 – 73).
