Evaluation of the long-term effect of foldable capsular vitreous bodies in severe ocular rupture

AIM:To evaluate the long-term effect of foldable capsular vitreous body(FCVB)in the treatment of severe ocular rupture to provide a practical basis for clinical selection.METHODS:A total of 26 patients(26 eyes),23 men and 3 women,with severe ocular rupture who underwent FCVB implantation between March 2018 and September 2018 were retrospectively analysed.All open ocular wounds located in zone III,with preoperative visual acuity grade IV and above(Snellen less than 4/200).The best corrected visual acuity(BCVA),intraocular pressure(IOP),cornea,anterior chamber,iris,lens,choroid,and retina were evaluated before and after the surgery.The subjective feeling and the location of FCVB were also assessed.RESULTS:The average age of the 26 patients was 36y(20-60y).Postoperative follow-up was from 10 to 14mo.At the end of follow up,BCVA was light perception(LP)in 10 cases,no light perception(NLP)in 13 cases,hand motions(HM)in 3 cases.IOP was 11±5 mm Hg.Corneal degeneration was in 3 cases and corneal endothelial dystrophy was in 7 cases.Shallow anterior chamber was in 8 cases and hyphema was in 8 cases.Organized membrane in the pupil was in 14 cases.Epiphora occurred in 3 cases.FCVB drainage tube exposed in 3 cases.All FCVBs were in their normal location and no rejection occurred.CONCLUSION:FCVB implantation is a long-term effective treatment and may provide a practical selection for severe ocular rupture.

Structure of vitreous body and its relationship with liquefaction

The aim of the study is to clarify the vitreous body structure and liquefaction phenomena. It was found that when melting a frozen rabbit vitreous body, the gel-sol transition phenomenon occurs and the gel structure is broken. This is almost like the liquefaction of the vitreous body in vivo. We try to clarify the liquefaction phenomenon by using this animal model. The native vitreous body has three dimensional meshwork structures. After liquefaction, it is changed into two parts, namely fiber aggregates and soluble amorphous aggregates. The surface of native vitreous body meshwork is mucopolysacharide, but that of fiber aggregates after liquefaction is changed into connective tissue, which means the conformational change of vitreous body in liquefaction. The soluble proteins after liquefaction were analyzed and identified as crystallin family. It is suggested that the liquefaction is induced by detachment of non-collagenous protein beads containing crystallins, resulting in the collapse of the three dimensional structure to release watery liquid trapped within. And the new gel-sol transition model of vitreous bod is proposed.

Clinical Efficacy and Safety of Foldable Capsular Vitreous Body Implant Surgery in 22 Cases of Silicone Oil-dependent Eyes

Objective This study aimed to evaluate the clinical efficacy and safety of foldable capsular vitreous body(FCVB)implant surgery in silicone oil-dependent eyes.Methods A total of 22 participants with silicone oil-dependent eyes who received treatment with FCVB implant surgery between January 2019 and June 2020 were included in this retrospective study.The intraocular pressure(IOP),best-corrected visual acuity(BCVA),demographic data,and any recorded complications were evaluated.Results The postoperative IOP(12.73±4.20 mmHg)was significantly improved(P=0.03)compared to the preoperative IOP(10.23±3.69 mmHg)(the main endpoint).There was no significant difference(P=0.33)in the final BCVA preoperation and 3rd month postoperation(the secondary endpoint).The most common postoperative complication was hyphema.Other common postoperative complications included corneal opacity,a shallow anterior chamber,and a low IOP.Conclusion FCVB implant surgery is a safe and effective method for treating silicone oil-dependent eyes;however,attention should be paid to the prevention and timely treatment of complications.

Vitreous substitutes: challenges and directions

The natural vitreous body has a fine structure and complex functions. The imitation of the natural vitreous body by vitreous substitutes is a challenging work for both researchers and ophthalmologists. Gases, silicone oil, heavy silicone oil and hydrogels, particularly the former two vitreous substitutes are clinically widely used with certain complications. Those, however, are not real artificial vitreous due to lack of structure and function like the natural vitreous body. This article reviews the situations, challenges, and future directions in the development of vitreous substitutes, particularly the experimental and clinical use of a new artificial foldable capsular vitreous body.

Expression levels of ROS and Atg proteins in the vitreous in rhegmatogenous retinal detachment

AIM:To detect the concentrations of reactive oxygen species(ROS),transient receptor potential mucin-1(TRPML1),and autophagy-related(Atg)proteins(LC3-Ⅰ,LC3-Ⅱ,and Beclin1)in vitreous humor of patients with simple rhegmatogenous retinal detachment(RRD).METHODS:RRD patients enrolled as the RRD group,and patients with idiopathic macular hole(IMH)and idiopathic macular epiretinal membrane(IMEM)were enrolled as control group.The levels of ROS,TRPML1,LC3-Ⅰ,LC3-Ⅱ,and Beclin1 in vitreous humor of patients in the RRD and control groups were detected by enzyme-linked immunosorbent assay(ELISA).RESULTS:The RRD group included 28 eyes 28 patients and had a higher concentration of ROS in vitreous humor(631.86±18.05 vs 436.34±108.22 IU/m L,P<0.05).The ROS level in patients with a wide retinal detachment(RD)extent(RD range≥1/2)was higher than that with a narrow RD extent(RD range<1/2,P<0.05).ROS concentration was negatively correlated with RD time(r=-0.46,P=0.01).The expression levels of LC3-Ⅰand Beclin1 significantly decreased in RRD(P<0.05),but there were no correlations with the RD time,RD extent,or macular involvement.CONCLUSION:In eyes with RRD,the concentration of ROS in vitreous humor increases and the expression levels of Atg proteins decrease,reflecting possibly that autophagy is inhibited.

从肺论治内障眼病初探

内障眼病外无见症,在现代眼科中主要包括眼后段疾病,其病因病机十分复杂。“目病常统于肺”是阐述内障眼病病因病机的重要理论。肺为相傅之官,主一身之气,在眼的生理功能和病因病机中具有关键作用。肺对眼内气、血、津液有疏通和调节作用,尤以肺气宣降为要,在视网膜血氧调节中可见一斑;玻璃体属于手太阴肺经,手太阴肺经为阴经气化活动的开始,玻璃体在内眼中亦是如此。在现代研究中也可发现,玻璃体微粒在内障眼病中起着调节和信使的作用。本文分别从理论研究和现代研究2个方面,分析从肺论治内障眼病的依据,着重从经络和藏象的角度进行探讨。

Characteristic analysis on susceptibility weighted imaging of intravitreous foreign body Of autologous eyelashes in rabbits

Objective： To explore the characteristics of susceptibility weighted imaging （SWI） of the intravitreous foreign body of autologous eyelashes in rabbits. Methods： A total of 12 New Zealand white rabbits, either sex, weighing 2.5-3.5 kg, and provided by the Experimental Animal Center of Henan Province were employed in this study. For each rabbit, 5 autologous eyelashes （1 cm in length and 0.2-0.3 mm in diameter） were implanted into the right ocular vitreum, while the left control ocular vitreum received sham operation but nothing was implanted. SWI sequential test was made 2 hours postoperatively. Then the rabbits were killed and the specimens of the vitreous bodies of the rabbits were obtained. Hematoxylin and eosin staining and histological examinations were performed. Results： The autologous eyelashes in 8 ocular vitreums of rabbits showed linear low signal intensity on the magni-tude images and susceptibility weighted images, but linear high signal intensity on the phase images. Among the 12 experimental rabbits, 5 eyelashes in the right vitreum were completely shown in 3 rabbits, partly shown in 5 rabbits （2 eyelashes shown in 3 rabbits and 3 eyelashes shown in 2 rabbits）, and not shown in 4 rabbits. Conelusions： SWI of the foreign body ofintravitreous autologous eyelashes in rabbits has its own characteristics. The combined application of SWI sequential magnitude images, susceptibility weighted images and phase images is helpful to the detection and diagnosis of intravitreous autologous eyelashes in rabbits.
