Angle-supported anterior chamber IOL and iris-clamp IOL are not standard options due to their associated complications. As a result, scleral fixation of the IOL has become the predominant choice in scenarios without sufficient capsular support. The evolution from sutured scleral suspension techniques for IOL to sutureless interscleral fixation methods and the introduction of novel scleral fixation IOL designs reflects surgeons’ efforts to improve surgical outcomes, streamline procedures and minimize postoperative complications. As a result, surgical techniques for scleral fixation of IOL continue to evolve. This article provides an overview of recent developments in scleral fixation of IOL.展开更多
糖尿病视网膜病变(diabetic retinopathy,DR)是由糖尿病所导致的最典型的微血管并发症之一。以往DR发病机制和治疗的研究主要集中在微血管;近年来,许多学者认为DR不仅仅是一种微血管病变,而且还伴有视网膜神经退行性变。近期研究表明,...糖尿病视网膜病变(diabetic retinopathy,DR)是由糖尿病所导致的最典型的微血管并发症之一。以往DR发病机制和治疗的研究主要集中在微血管;近年来,许多学者认为DR不仅仅是一种微血管病变,而且还伴有视网膜神经退行性变。近期研究表明,自噬与高迁移率族蛋白B1(high mobility group box protein 1,HMGB1)通过多条通路参与到糖尿病视网膜微血管病变和神经退行性变中,通过调控自噬或HMGB1可能为DR治疗提供一种新的思路。本文就自噬与HMGB1在糖尿病视网膜微血管病变和神经退行性变发病中的研究进展进行综述。展开更多
