Abstract：
UNASSIGNED: To study the morphological changes within mature senile cataracts on modified posterior segment optical coherence tomography (OCT).
UNASSIGNED: A cross-sectional observational study recruiting patients of mature cataracts admitted for elective cataract surgery in tertiary eye care. A modified OCT imaging of the lens was done and lenticular findings were noted by a single observer. Corresponding slit-lamp biomicroscopic findings and intraoperative experiences were also noted by a second observer and respective surgeons.
UNASSIGNED: Forty-four eyes of 44 patients were included. The mean age of patients was 65 ± 5.7 years. The intralenticular findings were uniform in groups of eyes, and they were characterized into three stages. First was a stage of early lamellar separation where small intralenticular clefts were noted superficially. Second was the stage of established lamellar separation where crescentic fluid clefts appeared interspersed between the lens fibers, and the depth increased as a function of severity. Both these stages did not show any distinct slit-lamp or intraoperative findings. A third stage of liquefaction identified as extensive lamellar separation with subcapsular fluid pockets. This was also reflected in slit-lamp biomicroscopy, showing the hydrated cortex with intraoperative challenges. Two cases showed peculiar changes, one of a hyperreflective subcapsular sheath and another of superficial nuclear lamellar separation.
UNASSIGNED: Mature cataracts may also show graded progression, which could be delineated on lenticular OCT. This could be of immense help in pre-operative planning and optimal management of these high-risk cases.

摘要：
■在改良的后段光学相干断层扫描（OCT）上研究成熟的老年性白内障的形态学变化。
■一项横断面观察性研究，招募在三级眼科护理中接受择期白内障手术的成熟白内障患者。进行晶状体的改良OCT成像,并且由单个观察者记录双凸透镜发现。第二位观察者和各自的外科医生也注意到了相应的裂隙灯生物显微镜发现和术中经验。
■纳入44例患者的44只眼。患者的平均年龄为65±5.7岁。眼睛群中的晶状体内发现是均匀的，它们分为三个阶段。首先是早期层状分离的阶段，在表面上注意到小的透镜内裂隙。其次是已建立的层状分离阶段，其中新月液裂隙出现散布在晶状体纤维之间，深度随着严重程度而增加。这两个阶段都没有显示任何明显的裂隙灯或术中发现。液化的第三阶段被确定为具有囊下流体袋的广泛的层状分离。这也反映在裂隙灯生物显微镜中，显示术中挑战的水合皮质。两个病例显示出奇特的变化，一种是超反射的囊膜下鞘，另一种是浅层核层状分离。
■成熟的白内障也可能表现出分级进展，可以在透镜状OCT上描绘。这对这些高风险病例的术前计划和最佳管理可能有很大帮助。
