Abstract
PURPOSE To explore lens capsule pathological characteristics in intraocular lens (IOL) dislocation after cataract surgery in patients with atopic dermatitis (AD). SETTING University hospital department of ophthalmology. DESIGN Case series with clinicopathological correlations. METHODS Lens capsules and surrounding tissues excised during surgery from eyes with AD (AD group) and eyes without AD (non-AD group) with IOL dislocation were histologically evaluated. Hematoxylin and eosin staining was used to assess abnormal changes in lens epithelial cells (LECs). Masson trichrome staining distinguished the fibrous metaplasia around the lens capsule into high-density and low-density fibrosis. Capsular splitting (thinning) was identified in both stained preparations. RESULTS The IOL dislocation morphology in the AD group (10 eyes of 10 patients) included 7 cases of capsular bag dislocation (CBD) and 3 cases of dead bag syndrome (DBS), with an average duration to IOL dislocation of 11.5 ± 5.6 years. All patients in the non-AD group (12 eyes of 12 patients) had CBD, averaging 10.2 ± 5.7 years to dislocation. Abnormal LECs, low-density fibrosis, and capsular splitting were observed in 9 (90), 9 (90), and 6 (60) of the patients in the AD group compared with 6 (50), 3 (25), and 2 (18), respectively, in the non-AD group (total n [%]). CONCLUSIONS Compared with the non-AD group, the AD group exhibited higher frequencies of morphological changes in LECs, low-density fibrosis around the lens capsule, and capsular splitting characteristics of DBS. These results suggest LEC degeneration and increased lens capsule fragility occurred in patients with AD.

Lin X, Ma D, Yang J. Exploring anterion capsular contraction syndrome in cataract surgery: insights into pathogenesis, clinical course, influencing factors, and intervention approaches. Front Med (Lausanne) 2024; 11:1366576. [PMID: 38439904 PMCID: PMC10911763 DOI: 10.3389/fmed.2024.1366576] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/06/2024] [Accepted: 02/05/2024] [Indexed: 03/06/2024] Open
Abstract
Anterior capsular contraction syndrome (ACCS) is a challenging complication that can occur following phacoemulsification cataract surgery. Characterized by capsular bag wrinkling, intraocular lens (IOL) decentration and tilt, ACCS can have negative effects on visual outcomes and patient satisfaction. This review aims to investigate the pathogenesis, clinical course, influencing factors, and intervention approaches for ACCS after cataract surgery. By understanding the underlying mechanisms and identifying factors that contribute to ACCS, surgeons can enhance their ability to predict and manage this complication. Various intervention strategies are discussed, highlighting their importance in reducing complications and improving surgical outcomes. However, further research is needed to determine optimal prevention and management strategies through long-term follow-up and comparative analyses. Advancements in this field will ultimately lead to improved visual outcomes and optimized cataract surgery for patients.

Liu M, Wang YC, Zhou J. Inhibition of suppressor of cytokine signaling-3 affects mesangial cell proliferation and cell cycle in mesangioproliferative glomerulonephritis. Kaohsiung J Med Sci 2021; 37:872-882. [PMID: 34213074 DOI: 10.1002/kjm2.12415] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/24/2021] [Revised: 03/31/2021] [Accepted: 06/07/2021] [Indexed: 11/09/2022] Open
Abstract
To explore the role of suppressor of cytokine signaling-3 (SOCS-3) in mesangial proliferative glomerulonephritis (MsPGN). SOCS-3 expression in kidney tissues from MsPGN patients was detected using immunohistochemistry. Double immunofluorescence staining was performed to investigate the localization of SOCS-3 with α-SMA in glomeruli. Heminephrectomized wild-type (WT) and SOCS-3-/- (KO) mice were injected with Habu-snake venom (HSV) to establish MsPGN models, and renal function were compared. Simultaneously, immunofluorescence, periodic acid-Schiff staining, Picrosirius red staining, as well as immunohistochemistry for PCNA, MAC-2 and type IV collagen in glomeruli were performed. In addition, primary mouse renal mesangial cells and SV40 MES-13 cells were transfected with SOCS-3 siRNA or SOCS-3 lentiviral activation particles, followed by EdU assay, flow cytometry, quantitative reverse transcription-polymerase chain reaction, and Western blotting. Mesangial SOCS-3 expression was enhanced in glomeruli of MsPGN patients, and SOCS-3 was well co-localized with activated α-SMA. After HSV injection, WT and KO mice presented with the increases in the serum creatinine, urea nitrogen, and urinary protein, especially in KO mice. Besides, SOCS-3-/- alleviated the hyperplasia of glomerular MCs in MsPGN mice, with the reductions in PCNA, MAC-2, and collagen deposition. Furthermore, SOCS-3 inhibition reduced the cell proportion at S phase to suppress cell proliferation, with the downregulations of Cyclin A, Cyclin D1, PCNA, and Ki-67. SOCS-3 knockout can alleviate the hyperplasia of glomerular MCs in MsPGN mice via affecting the cell cycle and proliferation of MCs, thus being a potential therapeutic target for MsPGN.
