外伤及刺囊手术后,或自发的囊膜破裂而造成晶体组织之自行吸收是常见的;在过熟期白内障,囊内皮质之吸收也能见到。但无外伤史而晶体组织自行吸收者则属罕见,作者报导一例如下: 88岁女性患者,20年来左眼患老年性白内障而近失明。近年来左眼视力逐步好转。该眼并无疼痛及炎症,因故未手术。检查见右眼晶体核硬化,前后皮质均混浊。左眼外斜,前房深,眼球运动时上方虹膜有震颤,晶性上半部皮质已完全吸收而透明,下半部呈灰白色三角形膜状,未见残核,下方囊膜上有虹膜后粘连,晶体上方原赤道部位置上有零星之 It is not uncommon for self-absorption of crystalline tissue after trauma and epidural operations, or spontaneous rupture of the capsular membrane. Absorption of intracortical cortex can also be seen in over-mature cataracts. However, there is no history of trauma and self-absorbed crystalline tissue is rare, the authors report an example as follows: 88-year-old female patient with left eye cataract who has been nearly blind for 20 years. In recent years, left eye vision gradually improved. The eye does not have pain and inflammation, because of no surgery. Check see the right eye crystal nucleus sclerosis, before and after the cortex are turbid. Left oblique outside the anterior chamber deep, eye movement above the iris tremor, crystalline upper half of the cortex has been completely absorbed and transparent, the lower half was gray triangular film, no residual nucleus, the lower capsule after the iris Adhesion, the crystal above the original equatorial part of the sporadic
