顫抖症是規則且重複性的動作,以較常見的本態性顫抖症為例,顫抖發生在雙手和頭,甚至聲音,在拿東西時最明顯,例如使用湯匙舀湯或寫字時,常造成生活上的不方便。 發現有1/3的人無法感受到「立體看東西的感覺」後,才了解到「腦內視力」的重要性。 歷經多次摸索試驗,終於完成「改善腦內視力專用的眼鏡」。 2)選擇觀察法:根據嬰兒生後喜歡看圖像畫面的特點,利用各種不同寬度的黑白條紋或棋盤方格作刺激源,顯示于嬰兒前,醫師站在選擇性觀看視表後面,通過小孔觀察嬰兒的反應,以此測量其視力情況。 1.光覺在弱視眼前放置中密度濾光片視力不降低,而器質性弱視視力降低。 在暗淡和微弱的光線下,弱視眼的視力改變不大。 3 外燴 .定期隨訪戴鏡兒童隨年齡增長,遠視度數漸減,因此須1∼1.5年驗光一次,在不影響斜度的原則下,逐漸減少遠視度數。

至於發病年齡各說不一,有說在生後6月∼8歲,有說35%∼70%小於2歲,也說在生後一年內發病甚稱幾乎皆為先天性的。 常見在3歲以後來診治,可能與集合張力隨年齡增長而下降有關,大部分因調節力減退而斜角變大,自感複視及視疲勞才來求治。 眼瞼常見的位置異常有眼瞼下垂、瞼退縮、瞼延滯和瞼痙攣。 視網膜和視路疾病主要表現為視覺障礙,如失明或偏盲等;眼球運動系統疾病則表現為眼球運動障礙,如復視、眼肌麻痹等;自律神經系統疾病多表現瞳孔運動障礙和腺體分泌異常,如視物模糊、羞明、流淚等。

2.治療弱視與訓練雙眼視功能弱視是一種與雙眼有關的病情,是在視覺發育早期,雙眼刺激輸入的競爭失去平衡的結果,佔優勢為健眼,劣勢則為弱視眼。 3)知覺性內斜,因生後早期眼部器質性病變,導致一眼視力低下,如角膜白斑、先天性葡萄膜炎、視神經萎縮或其他眼底病。 因幼兒集合力強,故一眼視力低下易引起內斜。

另一方面,神經病學確實包含視覺和眼球運動等有關的內容。 例如,顱神經的一半以上(Ⅱ、Ⅲ、Ⅳ、Ⅴ、Ⅵ、Ⅶ、Ⅷ)與眼直接相關,中樞神經系統有38%的神經纖維與視覺有聯繫;65%的顱內疾病有眼征。 可是,眼科醫師只熟悉神經性眼征的檢查手段,但對產生眼征的顱內病因和病位,不能作出正確的分析和判斷;同樣,神經科醫師雖對顱內結構(包括視路)比較熟悉,卻不諳眼征的臨床檢查與實驗室檢查,因而影響對檢查結果作出正確分析和判斷。

遮蓋法可在33cm與5m距處相繼檢查,如斜度或眼球轉動性質不同時則判有集合與分開功能不平衡情況。 three.頭顱外傷 眼眶骨折以及眶內出血,可導致眼外肌癱瘓,上、下斜肌最易受損;眶尖骨折能導致動眼、滑車、展神經麻痹以及三叉神經眼支受損,因爲動眼神經與副交感神經均嚴重受損,此時交感、副交感神經功能均出現障礙,可導致瞳孔大小正常,而對光反應消失。 臨牀上表現爲:眶內組織、上下瞼水腫、球結膜水腫,眼球突出,向各個方向運動麻痹,瞳孔散大,對光反射消失或額部疼痛、麻木,伴隨高熱與寒戰。
