Patient age, gender, indication for corneal transplantation and surgical technique were recorded and analyzed. RESULTS: Corneal transplantation were underwent in 1390 eyes of 1278 patients with a mean age of 44.9±18.1y during the period under review. The most common indication was infectious corneal ulcer (n=670; 48.2%), followed by corneal scar (n=333, 24.0% ), corneal dystrophy (n=138, 9.9%) and failed graft (n=112, 8.1%). Nearly all procedures performed were penetrating keratoplasty (n=1300, 93.5% ), with a few lamellar keratoplasty procedures performed: lamellar keratoplasty (n=52, 3.7%), Descemet's stripping automated endothelial keratoplasty (n =27, 1.9% ) and deep anterior lamellar keratoplasty (n =11, 0.8%).CONCLUSION: While the most common indication for keratoplasty was infectious keratitis, nearly all indications for corneal transplantation were managed with penetrating keratoplasty, However, lamellar keratoplasty techniques, including deep anterior lamellar keratoplasty and Descemet's stripping automated endothelial keratoplasty, are being performed with increasing frequency for isolated stromal and endothelial disorders, respectively,展开更多

The residents were randomly separated into two groups, WLT group and SST group. The residents in WLT group were asked to perform 10 trials of chopping using pig eyes and scored by the surgeons, and then they performed and scored using simulator for one time. The residents in SST group underwent 10 trials of chopping using simulator, and the simulator scored each trail. Then, this group were asked to perform the chopping using pig eyes and scored by the surgeons. At last, we investigated the residents’ satisfaction about the training.RESULTS: The demographic characteristics had no significant differences between the two groups. Recorded by the simulator, the residents in SST group got significantly higher overall score(83.90±1.31) than WLT group(78.73±1.92, P=0.03). And the residents in SST group got less corner area injured, and they spend less time than WLT group(P<0.05). Moreover, the residents in WLT group used more ultrasonic energy value than SST group(P=0.03). However, scored by the surgeons, the residents in two groups got nearly the same overall score. The residents in WLT group performed better on the frequencies of posterior capsule torn and incisional stress(P=0.03, 0.008, respectively). In the survey, the residents in two groups held the same opinion that the training was helpful and they strongly recommended this training. And all of them enjoyed the training, and enjoyed being randomized in their own group. However, with respect to the realistic character, the residents thought that WLT was better than SST(P<0.001).CONCLUSION: Both of the Eyesi surgical-stimulator and the wet-lab improve the residents’ chopping ability and each has its own advantages. The combination of the two training ways could be considered to be a part of the training curriculum for new residents.展开更多

文摘The organotypic retinal explant culture has been established for more than a decade and offers a range of unique advantages compared with in vivo experiments and cell cultures.However,the lack of systematic and continuous comparison between in vivo retinal development and the organotypic retinal explant culture makes this model controversial in postnatal retinal development studies.Thus,we aimed to verify the feasibility of using this model for postnatal retinal development studies by comparing it with the in vivo retina.In this study,we showed that postnatal retinal explants undergo normal development,and exhibit a consistent structure and timeline with retinas in vivo.Initially,we used SOX2 and PAX6 immunostaining to identify retinal progenitor cells.We then examined cell proliferation and migration by immunostaining with Ki-67 and doublecortin,respectively.Ki-67-and doublecortin-positive cells decreased in both in vivo and explants during postnatal retinogenesis,and exhibited a high degree of similarity in abundance and distribution between groups.Additionally,we used Ceh-10 homeodomain-containing homolog,glutamate-ammonia ligase(glutamine synthetase),neuronal nuclei,and ionized calcium-binding adapter molecule 1 immunostaining to examine the emergence of bipolar cells,Müller glia,mature neurons,and microglia,respectively.The timing and spatial patterns of the emergence of these cell types were remarkably consistent between in vivo and explant retinas.Our study showed that the organotypic retinal explant culture model had a high degree of consistency with the progression of in vivo early postnatal retina development.The findings confirm the accuracy and credibility of this model and support its use for long-term,systematic,and continuous observation.

文摘The retina,a crucial neural tissue,is responsible for transforming light signals into visual information,a process that necessitates a significant amount of energy.Mitochondria,the primary powerhouses of the cell,play an integral role in retinal physiology by fulfilling the high-energy requirements of photoreceptors and secondary neurons through oxidative phosphorylation.In a healthy state,mitochondria ensure proper visual function by facilitating efficient conversion and transduction of visual signals.However,in retinal degenerative diseases,mitochondrial dysfunction significantly contributes to disease progression,involving a decline in membrane potential,the occurrence of DNA mutations,increased oxidative stress,and imbalances in quality-control mechanisms.These abnormalities lead to an inadequate energy supply,the exacerbation of oxidative damage,and the activation of cell death pathways,ultimately resulting in neuronal injury and dysfunction in the retina.Mitochondrial transplantation has emerged as a promising strategy for addressing these challenges.This procedure aims to restore metabolic activity and function in compromised cells through the introduction of healthy mitochondria,thereby enhancing the cellular energy production capacity and offering new strategies for the treatment of retinal degenerative diseases.Although mitochondrial transplantation presents operational and safety challenges that require further investigation,it has demonstrated potential for reviving the vitality of retinal neurons.This review offers a comprehensive examination of the principles and techniques underlying mitochondrial transplantation and its prospects for application in retinal degenerative diseases,while also delving into the associated technical and safety challenges,thereby providing references and insights for future research and treatment.

文摘AIM:To explore the morphological and functional parameters to evaluate the effectiveness of intravitreal injections of ranibizumab(IVR)in treating macular edema(ME)secondary to retinal vein occlusion(RVO).METHODS:This retrospective study involved 65 RVO patients(65 eyes)who received IVR and were followedup for more than 3mo.ME was categorized into cystoid macular edema(CME),diffuse retinal thickening(DRT),and serous retinal detachment(SRD)according to optical coherence tomography(OCT)images.The comparison of best corrected visual acuity(BCVA;logMAR)and central macular thickness(CMT)among different follow-up points and those among 3 groups were performed by Kruskal-Wallis test.The correlation between BCVA and baseline parameters during treatment was analyzed using Spearman correlation analysis.RESULTS:BCVA tended to improve in all groups,with marked improvement in CME and DRT groups.CMT showed the greatest reduction after 1wk,and remained stable over the following 3mo.DRT patients had the worst BCVA and the highest CMT at baseline,but the differences became smaller after IVR treatment.CMT in SRD group was significantly better than in CME and DRT groups 3mo after IVR.Most patients of CME and SRD groups transitioned to a normal pattern at 3mo follow-up.DRT patients were most likely to transform into the other morphological groups,while SRD patients showed minimal transitions.BCVA at baseline was identified as the most important prognostic indicator in all 3 groups.Additionally,DRT patients with a longer clinical course,higher CMT and central retinal vein occlusion(CRVO)tend to exhibit worse BCVA after treatment.In addition,CRVO patients are more likely to have worse BCVA at 2 and 3mo follow-up compared with branch retinal vein occlusion(BRVO)patients in CME group.SRD patients with higher baseline CMT were prone to experiencing worse BCVA after treatment.CONCLUSION:The effectiveness of IVR is strongly correlated with baseline BCVA in all 3 groups.Baseline parameters including clinical course,CMT,and RVO position are also useful in predicting the BCVA at different time points after treatment.

文摘AIM:To investigate the etiology of ocular pathogens and to establish the various pathogens present in human immunodeficiency virus(HIV)patients with cytomegalovirus retinitis(CMVR).METHODS:A total of 17 HIV-infected patients with concomitant eye disorders were enrolled.Patients were divided into CMVR group(10 patients,18 eyes)and non-CMVR group(7 patients,9 eyes)based on clinical manifestations and the presence of cytomegalovirus(CMV)-DNA in ocular specimens.The viral load of CMV was assessed using polymerase chain reaction in aqueous humor,vitreous fluid,and peripheral blood samples of patients in the CMVR group.Additionally,peripheral blood CD4^(+)T cell counts were measured in both groups.RESULTS:In the CMVR group,the CMV-DNA load in the vitreous and aqueous humor samples was substantially higher than in the peripheral blood samples(P<0.01).CMVDNA load in the aqueous humor and vitreous samples of the two eyes in the CMVR group was determined to be statistically significant(10 patients,16 eyes,P=0.018,0.012).Peripheral blood CD4^(+)T cell counts in the CMVR group were adversely linked with the CMV-DNA load in both the aqueous humor and peripheral blood(P=0.005,0.048).Compared with the non-CMVR group,the peripheral blood CD4^(+)T cell count in the CMVR group decreased significantly(P=0.014).The peripheral blood CD4^(+)T cell count exceeded 300 cells/μL in 85.71%of non-CMVR patients,whereas it was below 100 cells/μL in 90.00%of the CMVR group.The intraocular specimens of the patients who underwent CMVR testing did not include any additional infections.CONCLUSION:In HIV-associated CMVR patients,there may exist alternative,yet unidentified,infection pathways for intraocular CMV in addition to the conventional route.The substantial difference in CMV-DNA load between the eyes of most CMVR patients suggests that CMV may originate from different sources in each eye.The proportion of peripheral blood CD4^(+)T cells in HIV patients is negatively correlated with the quantity of CMV viruses in their eyes.The peripheral blood count of<100 cells/μL indicates a considerable increase in the risk of concurrent CMVR.Multi-ocular pathogen presentations are uncommon in HIV individuals with CMVR.
文摘Dry eye disease(DED)is a multifactorial disorder that disturbs ocular surface equilibrium,considerably diminishing quality of life.Present therapies only offer symptomatic alleviation.Stem cell treatment,especially mesenchymal stem cells(MSCs),has surfaced as a viable approach for tissue regeneration and immunological regulation in DED.Preclinical and early clinical investigations indicate that MSCs can improve lacrimal gland functionality,diminish inflammation,and facilitate corneal regeneration.Nonetheless,obstacles persist in enhancing MSC viability,determining the optimal MSC source,and guaranteeing sustained therapeutic effectiveness.Additional extensive randomized clinical trials are required to confirm the efficacy of MSC-based therapies for severe DED.
