早中期白內障(一)

西醫的認識:

        凡是各種原因如老化,遺傳、局部營養障礙、免疫與代謝異常,外傷、中毒、輻射等,都能引起晶狀體代謝紊亂,導致晶狀體蛋白質變性而發生混濁,稱為白內障,此時光線被混濁晶狀體阻擾無法投射在視網膜上,就不能看清物體。世界衛生組織從群體防盲,治盲角度出發,對晶狀體發生變性和混濁,變為不透明,以至影響視力,而矯正視力在0.7(4.9)或以下者,才歸入白內障診斷范圍。分先天性和后天性。

中醫的認識:

       中醫古籍中無白內障之名。今之所謂白內障一病,包括在內障眼病這一大類之中,如圓翳內障、如銀內障等。唐代《外臺秘要》將本病稱為“腦流青盲眼”,謂:“無所因起,忽然漠漠,不痛不癢……小珠子里,乃有其障,作青白色,雖不辨物,猶知明暗三光。”癥狀描述頗為仔細。由于各人睛珠混濁的程度、顏色、形態、位置及原因不同,名稱各有所異。宋元時代《秘傳眼科龍本掄》一書,對內障眼病分類有23種之多,每種癥候,均作了具體論述,后世的《世醫得效方》、《審視瑤函》、《證治準繩》、《目經大成》等醫書也多有論及。在病機方面,《龍木論》認為主要由肝風或肝臟積熱所致,元代倪維德則強調“陰弱不能配陽”,腎陰不足為其本。明代《針灸大成》認為其病因為“怒氣傷肝,血不就舍,腎水枯竭,氣血耗散。”在治療方面,古代治法也多種多樣,藥物治療,《千金要方》中的神曲丸(即磁株丸)被后世醫家譽為“開瞽第一品方”,《龍本論》中還載有20首治療內障眼病的專方。針灸治療,早在《針灸甲乙經》就有記載,以后的《千金方》、《龍木論》均有許多介紹。《針灸大成》在提出針灸處方的同時,也客觀地指出“亦難治療”。此外,中醫還較早運用手術治療本病,如《外臺秘要》“用金篦決”,《龍木論》較詳細地論述了金針撥障術。

  

簡要臨床分類:

臨床上將老年性白內障分為皮質性,核心性和囊下三種類型。

1,皮質性白內障(cortical cataract)以晶體皮質灰白色混濁為主要特征,其發展過程可分為四期:初發期,未成熟期,成熟期,過熟期。

2,核心性白內障(nuclear cataract) 晶體混濁多從胚胎核開始,逐漸擴展至成人核,早期呈黃色,隨著混濁加重,色澤漸加深如深黃色,深棕黃色,核的密度增大,屈光指數增加,病人常訴說老視減輕或近視增加,早期周邊部皮質仍為透明,因此,在黑暗處瞳孔散大視力增進,而在強光下瞳孔縮小視力反而減退,故一般不等待皮質完全混濁即行手術。

3,后囊下白內障(posterior subcapsular cataract),因混濁位于視軸區,早期即影響視力。

  

起病要點:

 西醫認為凡是各種原因如老化,遺傳,局部營養障礙,免疫與代謝異常,外傷,中毒,輻射等,都能引起晶狀體代謝紊亂,導致晶狀體蛋白質變性而發生混濁,導致白內障。

 中醫認為本病由年老體衰,或先天稟賦不足,或外傷、暴力等原因引起,其病機主要有以下兩個方面:包括肝腎陰虛和脾胃氣虛。

一、肝腎陰虛:肝開竅于目,目得肝血而能視,瞳神為水輪屬腎,腎精充足則精采光明。若因年老體衰,精氣不充,或因勞心過多,陰血專耗散,或先天稟賦不足,則可導致肝血不足、肝陰虧損及腎精不足,且肝腎同源,精血互生,故肝腎陰虛常同時存在。精血不足,肝腎兩虛,則晶珠失養而成內障。

二、脾胃氣虛:年老體弱,脾胃氣虛,運化失司,氣血生化匱乏,目失濡養,則導致本病的發生,且脾失健運,氣機升降失常,清氣不升,濁氣不降,亦可導致本病。

三、年老之人皆少動多靜之體,血運因之而遲滯緩慢,久而形成瘀血。又因外傷、暴力,晶珠驚震,氣滯血瘀,侵擾神水而逐漸混濁變白。另外,瘀血不去,新血不生,血不充盈,也可使晶珠失榮,以致內障漸生。
